Answer:
(1/3)(9x+27) > x + 33
multiply out the 1/3
3x + 9 > x + 33
subtract x and 9 from both sides
2x > 24
x > 12
D) because you dont include the 12

Given A(-2,8) and B(4,14), what is the y-intercept of the line AB?
A:-2
B:1
C:10
D:14
Answers
Answer: C:10
Step-by-step explanation:
Equation of a line passes through (a,b) and (c,d) :
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
Equation of line passes through A(-2,8) and B(4,14) will be :
[tex]y-8=\dfrac{14-8}{4-(-2)}(x-(-2))\\\\\Rightarrow\ y-8= \dfrac{6}{6}(x+2)[/tex]
[tex]\Rightarrow\ y-8=x+2\\\\\Rightarrow\ y= x+2+8\\\\\Rightarrow\ y=x+10[/tex]
For y-intercept , put x= 0 , we get y= 10
So, the y-intercept = 10
Thus , correct option = C:10
Anna wants to add compatible numbers to find the following sum. 27.95 + 19.37 + 34.05 + 21.63 Which pairs of numbers are compatible? Choose Yes or No for each pair. 27.95 and 34.05 Choose.. 27.95 and 21.63 Choose... 19.37 and 34.05 Choose... 19.37 and 21.63 Choose...
Answers
Answer:
27.95 and 34.05 are compatible because when you add up the decimals, the equal 0, which makes it easier to add. 27. 95 + 34.05 = 61.00.
Same with 19.37 and 21.63, it adds up to 40.00
The answer to all of this would be 101.00
can someone one please explain this to me and what to do it say combing like trems
Answers
Answer:
A. 5x+y+3
Step-by-step explanation:
to combine like terms you get the numbers that have the same variable. you will combine 2x and 3x and to combine them you add them 2x+3x and it equals 5x. you will do the same for the numbers left... -2y and 3y = 1y or y and 3 is left so we dont do nothing and after you do that you will put it in an equation variables go first and you order them in alphabetical order so 5x will go first then y and lastly the 3
so
2x+3-2y+3x+3y
you would add the like terms
by the way, each one keeps the sign before it and if it doesent have a sign for example at the beginning, its positive
2x+3x= 5x
3 (theres only one without a variable so no need to add)
-2y+3y= 1y aka y
sooo
your answer is 5x+3+y
or 5x+y+3 cuz the order doesnt matter for addition

Answers
Answer:
1) Solving the term [tex](3x + 5)(2x - 3)[/tex] using F.O.I.L we get [tex]\mathbf{6x^2+x-15}[/tex]
2) solving the term [tex](x + 2)(x - 13)[/tex] using F.O.I.L we get [tex]\mathbf{x^2-11x-26}[/tex]
3) Solving [tex](x+5)^2[/tex] using square of binomial we get [tex]\mathbf{x^2+10x+25}[/tex]
4) Solving [tex](x+5)^2[/tex] using square of binomial we get [tex]\mathbf{x^2-6x+9}[/tex]
Step-by-step explanation:
1) (3x + 5)(2x - 3). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have [tex](3x + 5)(2x - 3)[/tex]
First: 3x(2x)
Outer: 3x(-3)
Inner: 5(2x)
Last: 5(-3)
Solving we get:
[tex](3x + 5)(2x - 3)\\=3x(2x)+3x(-3)+5(2x)+5(-3)\\=6x^2-9x+10x-15\\=6x^2+x-15[/tex]
So, solving the term [tex](3x + 5)(2x - 3)[/tex] using F.O.I.L we get [tex]\mathbf{6x^2+x-15}[/tex]
2) (x + 2)(x – 13). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have [tex](x + 2)(x -13)[/tex]
First: x(x)
Outer: x(-13)
Inner: 2(x)
Last: 2(-13)
Solving we get:
[tex](x + 2)(x - 13)\\=x(x)+x(-13)+2(x)+2(-13)\\=x^2-13x+2x-26\\=x^2-11x-26[/tex]
So, solving the term [tex](x + 2)(x - 13)[/tex] using F.O.I.L we get [tex]\mathbf{x^2-11x-26}[/tex]
3) (x + 5)^2. Solve using the square of Binomial.
The square of binomial is: [tex](a+b)^2=a^2+2ab+b^2[/tex]
Solving:
[tex](x+5)^2\\=(x)^2+2(x)(5)+(5)^2\\=x^2+10x+25[/tex]
So, solving [tex](x+5)^2[/tex] using square of binomial we get [tex]\mathbf{x^2+10x+25}[/tex]
4) (x -3)^2. Solve using the square of Binomial.
The square of binomial used is: [tex](a-b)^2=a^2-2ab+b^2[/tex]
Solving:
[tex](x-3)^2\\=(x)^2-2(x)(3)+(3)^2\\=x^2-6x+9[/tex]
So, solving [tex](x+5)^2[/tex] using square of binomial we get [tex]\mathbf{x^2-6x+9}[/tex]

In City A, the temperature rises 4(degrees)F from 8 A.M. To 9 A.M. Then the temperature drops 7F from 9 A.M. To 10 A.M. In City B, the temperature drops 6F from 8 A.M. To 9 A.M. Then the temperature drops 2F from 9 A.M. To 10 A.M. Write an expression that represents the change in temperature from 8 A.M. To 10 A.M. For each city. Simplify and interpret each sum. Use pencil and paper. Which city has the greater change in temperature?
Answers
Answer:
City A:
[tex]A - 3[/tex]
City B:
[tex]B - 8[/tex]
City B has a greater change in temperature.
Step-by-step explanation:
City A:
Let the initial temperature of city A at 8 AM = [tex]A\ ^\circ F[/tex]
Temperature change from 8 AM to 9 AM: 4[tex]^\circ F[/tex] rise
Temperature at 9 AM = [tex](A+4)\ ^\circ F[/tex]
Temperature change from 9 AM to 10 AM: 7[tex]^\circ F[/tex] drop
Temperature at 9 AM = [tex](A+4 -7 )\ ^\circ F = (A-3)\ ^\circ F[/tex]
Total change in temperature = [tex](A - 3) - A = 3\ ^\circ F[/tex] drop
City B:
Let the initial temperature of city B at 8 AM = [tex]B\ ^\circ F[/tex]
Temperature change from 8 AM to 9 AM: 6[tex]^\circ F[/tex] drop
Temperature at 9 AM = [tex](B-6)\ ^\circ F[/tex]
Temperature change from 9 AM to 10 AM: 2[tex]^\circ F[/tex] drop
Temperature at 9 AM = [tex](B-6 -2 )\ ^\circ F = (B-8)\ ^\circ F[/tex]
Total change in temperature = [tex](B - 8) -B = 8\ ^\circ F[/tex] drop
Therefore, the answer is:
City B has a greater change in temperature.

An angle measures 10 more than four times a number. It’s supplement is two more than three times the number. What is the measure of each angle in degrees
Answers
Answer:
4x +10 + 3x +2 = 180 (since they're supplementary, the angles together =180)
7x +12 =180 (combine like terms on left side, and subtract 12 from both sides)
7x = 168 (divide both sides by 7 to isolate x)
x= 24
angle 1 = 4(24)+10 (plug x into the expression for each angle, and solve)
..................96 +10
angle 1 = 106 degrees (the measure of the first angle)
angle 2 = 3(24) +2
..................72 +2
angle 2 = 74 (the measure of the second angle)
106 +74 =180 (the two add up to 180, so they're supplementary)

Answer: 54/4 or 13 2/4
Step-by-step explanation: So first you have to make both fractions into improper fractions. So 15(4)+3=63 over the denominator which is 4. And 2(4)+1=9 over the denominator which is 4. Then subtract the two fractions: 63/4-9/4, and since the two denominators are the same you keep it as 4. So the answer would be 54/4 or if you need it to be a mixed number, 13 2/4.

Answer:
x = 63; y = 27
Step-by-step explanation:
x + 117 = 180
x = 180 - 117
x = 63
x + y = 90
63 + y = 90
y = 90 - 63
y = 27
Bam! UwU
Lol Hope this helps !
That is a question about angles.
There are two informations in that image that we should to note:
The sum of the angles x and y is a right angle. A right angle is a 90° angle. That is to say [tex]x + y = 90[/tex].The sum of the angle x and the 117° angle is a straight angle. A straight angle is an angle that measure 180°. In other words, [tex]x + 117 = 180[/tex].With these two informations we can solve that question. The first step is solve the second equation, and we will find the x value. Finally, we change the x value in the first equation and we find the y value. Let's solve the equations:
Second equation:[tex]x + 117 = 180\\x = 180 - 117\\x = 63[/tex]
So, the value of x is 63°. Let's replace the x value in the first equation.
First equation:[tex]x+y = 90\\63 + y = 90\\y = 90 - 63\\y = 27[/tex]
Thus, the value of y is 27°.
Therefore, the correct option is the option says x = 63°, y = 27°.

A furnace operates at 2,300°F. Before it can be used to extract metal from an ore, the temperature must be raised to 3,600°F. This takes place at a rate of 250°F per quarter hour. Write an equation that gives the furnace temperature, T, after, q, quarter hours.
Answers
Answer:
T = 2300 + 250q
Step-by-step explanation:
Given that:
Initial temperature = 2300 F
Extraction temperature = 3600 F
Rate of temperature increase = 250 F per quarter hour, q
Temperature of furnace after q quarter hours ;
(Initial temperature + rate of temperature increase * number of quarter hours )
(2300 + 250 * q)

Remember, the sum of all the angles in a triangle equals 180 degrees.
Moreover, looking at the diagram, we can see sides BA and BC are identical. This means this triangle is an isosceles triangle. Remember, all isosceles triangles will also have two identical angles. In this case, angles A and C are identical (meaning A and C are both 73 degrees).
So, if A is 73 degrees, C is 73 degrees, and we know that all the angles must sum to 180 degrees (so A + B + C = 180), then we can construct the following equation to solve for x:
[tex]73+73+6x+4=180\\150+6x=180\\6x=180-150\\6x=30\\x=\frac{30}{6}\\x=5[/tex]
