Evaluate f(x)=7x+7 when x=-9
Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday. What percent of 8th graders did not try out for football?
Answer:
87.5%
Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %

What is the value for A? What is the value for B? What is the value for C? What is the value for D?
Step-by-step explanation:
step 1. we must assume the ratio of flour to sugar is 2:1.
step 2. A = 2(3/4) = 3/2 1-1/2.
step 3. B = 1-3/4(1/2) = 7/4(1/2) = 7/8
step 4. C = 1(2) = 2
step 5. D = 2-1/2(1/2) = 5/2(1/2) = 5/4 = 1-1/4.

Mary is baking cookies, and the recipe calls for 1 1/2 cups of sugar. If she has 6 1/3 cups of sugar left after she bakes the cookies, how much sugar (s) did she have before she started baking cookies? Which equation would you use to solve for (s)? *
s + 1 1/2 = 6 1/3
6 1/3 - s = 1 1/2
s - 1 1/2 = 6 1/3
1 1/2 + s = 6 1/3
Answer: 4 5/6
Step-by-step explanation: 4 5/6+ 1 3/6(aka 1 1/2)= 6 2/6 (aka 6 1/3)
Solve the following equations:
x/3+1=7/5
Answer:
8/5..............…is the answer
Answer:
Standard Form: 6/5 Mixed Number: 1 1/5 Decimal: 1.2
Step-by-step explanation:
1. Subtract 1 from both sides of the equation
x/3 + 1 = 7/5
x/3 + 1 - 1 = 7/5 - 1
2. Simplify
2a.
x/3 + 1 - 1 = 7/5 - 1
x/3 = 7/5 - 1
2b.
x/3 = 7/5 - 1
x/3 = 2/5
3. Multiply all terms by the same value to eliminate fraction denominators
x/3 = 2/5
3 x x/3 = 3 x 2/5
4. Simplify
4a. Cancel multiplied terms that are in the denominator
cross out the threes in 3 x x/3 then you should get x = 3 x 2/5
4b. Multiply the numbers
x = 3 x 2/5
x = 6/5
And your answer should be 6/5|

13.) The leading scorer in your high school's hockey league finished the season with an average of 4 goals per game for 15 games. As the leagues
second leading scorer, you have an average of 4 goals per game for 14 games. You still have to play your last game. How many goals must you
score in the final game to overtake the leagues' leading scorer?
Answer:
5 goals
Step-by-step explanation:
4 goals per game for 15 games means a total of 60 goals in that season. You have 4 goals per game for 14 games meaning you have a total of 56 goals. To overtake the leading team you must score a minimum of 5 goals to become the leading scorer. (Double-check to make sure I am correct)
Angle E and Angle F are Vertical Angles, If measure of Angle E is 3x + 33 and the measure of Angle F is 4x + 8, what is the value of x?
Answer:
Remember vertical angles are congruent so you can set these expression equal to each other and then solve the equation.
Angle F = angle E
4x + 8 = 3x + 33
Now solve for the x variable.

100 POINTS! The midpoint of GH is M(4, -3). One endpoint is G(-2, 2). Find the coordinates of endpoint H.
Answer:
(10, -8)
Step-by-step explanation:
Answer:
solution given:
G(x1,y1)=(-2,2)
H(x2,y2)=(x,y)
Mid point M(a,b)=(4,-3)
we have
(a,b)=((x1+x2)/2,(y1+y2)/2)
(4,-3)=((-2+x)/2,(2+y)/2)
comparing corresponding value
4=(-2+x)/2
8+2=x
x=10
again
(2+y)/2=-3
2+y=-6
y=-6-2
y=-8
So coordinates of H is (10,-8).
x - y = -2
4x - y = 4
[tex] \begin{cases} x - y = - 2 \\ 4x - y = 4 \end{cases}[/tex]
Use the elimination method as it is faster. We have to eliminate the y-term. (You can eliminate the x-term but it takes longer than eliminating y-term.)Simply multiply the negative one in one of the equations.
[tex] \begin{cases} - x + y = 2 \\ 4x - y = 4 \end{cases}[/tex]
We can finally eliminate the y-term by adding both equations.
[tex]( - x + 4x) + (y - y) = 2 + 4 \\ 3x + 0 = 6 \\ 3x = 6 \\ x = \frac{ 6 }{3} \longrightarrow \frac{ \cancel{6}}{ \cancel{3}} = 2 \\ x = 2[/tex]
Substitute the value of x in any given equations. I will substitute in the first equation.[tex]x - y = - 2 \\ 2 - y = - 2 \\ 2 + 2 = y \\ 4 = y[/tex]
Check the answer by substituting the value of x and y in both equations.First Equation
[tex]x - y = - 2 \\ 2 - 4 = - 2 \\ - 2 = - 2 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Second Equation
[tex]4x - y = 4 \\ 4(2) - 4 = 4 \\ 8 - 4 = 4 \\ 4 = 4 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Hence, the solution is (2,4).

the first 4 terms and the 10th term for 3n+4
Answer:
first 4 terms =7,10,13,16
10th term = 34
Step-by-step explanation:
3n+4
3(1)+4=7
3(2)+4=10
3(3)+4=13
3(4)+4=16
7,10,13,16
10th term = 3(10)+4= 34
The first four terms of the sequence having nth term 3n+4, are 7, 10, 13, 16 and the 10th term is 34.
What is arithmetic sequence ?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.
Given that,
The nth term of a sequence is given by 3n+4,
To find the first 4 terms, substitute the values of n,
At n=1, the first term = 3(1) + 4 = 3 + 4 = 7
At n=2, the second term = 3(2)+4 = 6 + 4 = 10
At n=3, the third term = 3(3) + 4 = 9 + 4 = 13
At n=4, the fourth term = 3(4) + 4 = 12 + 4 = 16
For 10th term, substitute n=10.
At n=10, the tenth term = 3(10) + 4 = 30 + 4 = 34
The first four terms are 7, 10, 13, 16 and the 10th term is 34.
