Which of the following values of x will result in a true statement when substituted into the given equation? -3(x – 2) = 9 A. x = 1 B. x = -1 C. x = 3 D. x = -3.

Answers

Answer 1

Answer:

B. x = -1

Step-by-step explanation:

-3(x - 2) = 9

Divide both sides by the coefficient of (x - 2) which is -3

[tex]\frac{-3(x - 2)}{-3} =\frac{9}{-3}[/tex]

x - 2 = -3

Add 2 to both sides of the equation

x - 2 + 2 = -3 + 2

x = -1

Hope this helps :)

It is 270. Multiply 18 by 12 for the square portion of the shape. Then multiply 18 by 6 for the right triangle. I got 6 by subtracting the bottom line by the top line of the quadrilateral.

A quadrilateral has one right angle. The second angle is 95 ^{\circ}
∘
. The third angle is 105 ^{\circ}
∘
.

​What is the measure of the fourth angle?

Answers

Answer : 70°

Explanation :

Quadrilaterals have a total measure of 360°, so by adding the angles you already know - 90 + 95 + 105 - and subtracting that from 360, you get an answer of 70
70 is answer the answer sorry is wrong

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)

Answers

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)

Answer: 101 Degrees for angle BCD

Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

The answer is in the image below.
