[tex] \red{ \boxed{ \bold{2x - 3y + 15=0}}}[/tex]
Explanation
[tex] slope \:of \:the\: required\:\: line \implies\\\frac{9-6}{6-(-3)}=\frac{6}{9} [/tex]
[tex] equation \:of \:the\: required\:\: line\implies\:\\y - 3 = \frac{6}{9} (x + 3)[/tex]
[tex] \implies \: 9y - 27 = 6x + 18[/tex]
[tex] \implies \: 6x - 9y + 45=0[/tex]
[tex] \implies\:2x-3y+15=0[/tex]
Hence the equation of the line is

Answer:
55 i believe
28 + 27 = 55
Answer:
a = 7.4
Step-by-step explanation:
Since this is a right triangle, we will use the Pythagorean theorem:
c^2 = a^2 + b^2
28^2 = a^2 + 27^2
784 = a^2 + 729
55 = a^2
a = 7.4
Find FH
FH = {Blank}
Answer:
22
Step-by-step explanation:
[tex]FH=8+14=22[/tex]
Answer:
FH = 22
Step-by-step explanation:
The equation will be,
→ FH = FG + GH
Then the value of FH will be,
→ FH = 8 + 14
→ [ FH = 22 ]
Hence, the value of FH is 22.

Answer:
3/12 or 1/4
Step-by-step explanation:
To do this you can just increase the denominator by 1, at least for this question
3/11 is around 0.27, while 3/12 is 0.25. 2/11 is 0.19, which is smaller than 0.25, so
3/12 is a justificable answer.

Answer:
Step-by-step explanation:
In order to determine the information you're being asked for, you need to complete the square on that quadratic. The first step is to move the constant over to the other side of the equals sign:
[tex]x^2-2x=3[/tex]
Here would be the step where, if the leading coefficient isn't a 1, you'd factor it out. But ours is a 1, so we're good there. Now take half the linear term (the term with the single x on it), square it, and add it to both sides. Our linear term is a -2. Half of -2 is -1, and -1 squared is +1. We add +1 to both sides giving us this:
[tex]x^2-2x+1=3+1[/tex]
Now we'll clean it up a bit. The right side becomes a 4, and the left side is written as its perfect square binomial, which is the whole reason we did this. That binomial is
[tex](x-1)^2=4[/tex] (set equal to the 4 here). Now we'll move the 4 back over and set the whole thing back equal to y:
[tex]y=(x-1)^2-4[/tex]
From this it's apparent what the vertex is: (1, -4),
the axis of symmetry is x = 1, and
the y-intercept is found by setting the x's equal to 0 in the original equation and solving for y. So the y-intercept is (0, -3).
Your choice for the correct answer is the very last one there.
Does (2,2) make the inequality 5x+4y>20 true?
Answer:
No
Step-by-step explanation:
substitute the coordinates of the point into the left side of the inequality and check the value obtained against the right side.
5(2) + 4(2) = 10 + 8 = 18 < 20
then (2, 2 ) does not make the inequality true
Asap answer plssss!, John can do a piece of work in 6 days. When he and Marsha work together, it takes only 4 days. How long will it take Marsha to do the work if she works alone? asap answer plssssss
Answer:
12 days
Step-by-step explanation:
Let the amount of work be x.
John:
6 days = x
1 day = [tex]\frac{1}{6}[/tex]x
Together:
4 days = x
1 day = [tex]\frac{1}{4}[/tex]x
Marsha:
1 day = [tex]\frac{1}{4}[/tex]x - [tex]\frac{1}{6}[/tex]x
= [tex]\frac{6}{24}[/tex]x - [tex]\frac{4}{24}[/tex]x
= [tex]\frac{2}{24}[/tex]x
= [tex]\frac{1}{12}[/tex]x
Marsha can do [tex]\frac{1}{12}[/tex] of the work in 1 day.
No. of days taken (Marsha) = x ÷ [tex]\frac{1}{12}[/tex]x
= 12

Please help math 50 points please dont lie
Answer:
8,250
Step-by-step explanation:
10 to the power of 2 is 100, move the decimal 2 spaces to the right.
Answer:
Hi, i think the answer would be the third option, 8,250.
Step-by-step explanation:
You do the exponents first in this equation according to the acronym PEMDAS. 10 to the second power is 100, so now you have
82.5 × 100
This would be equal to moving the decimal point two spaces to the right, giving us 8,250 as the answer

For the cubic x^3 + 7x^2 + 13x + 3 has only one rational zero, x=-3. Use polynomial long division to show that the remainder is zero when dividing the cubic by x+3. Then use the quadratic formula to find the other two (irrational) zeroes.
The two irrational roots of the cubic equation are - 2 + √3 and - 2 - √3, respectively.
How to find the two remaining zeroes of the cubic equation
In this problem we find the definition of a cubic equation, of which one root is known and we need to find the two missing roots. By algebraic handling, the cubic equation is:
f(x) = x³ + 7 · x² + 13 · x + 3
f(x) = (x³ + 3 · x²) + (4 · x² + 12 · x) + (x + 3)
f(x) = x² · (x + 3) + 4 · x · (x + 3) + (x + 3)
f(x) = (x² + 4 · x + 1) · (x + 3)
Then, the roots of x² + 4 · x + 1 are found by using the quadratic formula:
x² + 4 · x + 1 = (x + 2 - √3) · (x + 2 + √3)

. A electric jug was sold allowing 20% discount
with Profit of Rs.120. If the jug was sold
allowing 30% discount, there would have
been loss of Rs. 270. Find the MP of the jug.
solu
9514 1404 393
Answer:
marked price = Rs. 3900
Step-by-step explanation:
The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.
The marked price is Rs. 3900.
_____
Check
A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf x \approx 9.7}}[/tex]
Step-by-step explanation:
This is a right triangle, which we know because of the square in the corner of the triangle. We can use the right triangle trigonometric ratios.
[tex]sin( \theta) =opposite/hypotenuse[/tex] and [tex]cos (\theta) = adjacent /hypotenuse[/tex] and [tex]tan (\theta)=opposite/adjacent[/tex]
First, identify each side of the triangle as adjacent, opposite, or hypotenuse, relative to the 68 degree angle.
The x is next to, or adjacent, to the angle. The 24 is opposite. We are not given the hypotenuse.
[tex]adjacent= x \\opposite= 24 \\hypotenuse= unknown[/tex]
Since we have the adjacent and opposite, we must use tangent.
[tex]tan (\theta)=\frac{opposite}{adjacent}[/tex]
Substitute the values in. The theta (θ) is the angle.
[tex]tan (68)=\frac{24} {x}[/tex]
Solve for x. One way is by cross multiplying.
[tex]\frac{tan(68)}{1}=\frac{24}{x}[/tex]
Multiply the 1st numerator by the 2nd denominator. Then, multiply the 1st denominator by the 2nd numerator.
[tex]tan (68)*x=1*24[/tex]
[tex]tan(68)*x=24[/tex]
Evaluate tan(68) using a calculator.
[tex]2.47508685*x=24[/tex]
Divide both sides of the equation by 2.47508685. This will isolate the variable x. ( We divide because multiplication is occurring between 2.47508685 and x, and division is the inverse of multiplication).
[tex]\frac{2.47508685*x}{2.47508685}=\frac{24}{2.47508685}[/tex]
[tex]x=\frac{24}{2.47508685}[/tex]
[tex]x=9.69662943[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round up. The 6 becomes a 7.
[tex]x \approx 9.7[/tex]
In this right triangle, x is equal to about 9.7

-4+5x-7=10+3x-2x. Solve for x
Answer:
-4 + 5x - 7 = 10 + 3x - 2x
5x - 3x + 2x = 10 + 4 + 7
4x = 21
x = 21/4
x = 5 1/4 or 5.25
Answer: 5=x
Step-by-step explanation:
-4+5x-7=10+3x-2x
Combine like terms:
-10+5x=10+x
Subtract 10 on both sides:
-10-10+5x=10-10+x
-20+5x=x
Subtract 5x on both sides:
-20+5x-5x=x-5x
-20=-4x
Divide -4 on both sides:
-20/-4=-4x/-4
5=x
