Answer:
(x + 2)² = 7
Step-by-step explanation:
We have to complete the square in the given equation
3x² + 12x = 9
3x² + 12x - 9 = 0
3[x² + 4x -3] = 0
3[x² + 2(2x) + 4 - 4 - 3] = 0
3[x² + 2(2x) + 4] - 3 × 7 = 0
3[x² + 2]² - 21 = 0
(x + 2)² = = 7
Therefore, the square form of the equation is (x + 2)² = 7
Hope this helps (:
Step-by-step explanation:
90*8.25=742 rounds to 675 because its the closest. 85-95=10 divided by 2=5+85=90. 9-7.5=1.5 divided by 2=0.75+7.5=8.25. thats how i got those numbers. THE ANSWER IS C
(5x) / (2/11) = 3 / (1/5)
cross multiply
(5x)(1/5) = (2/11)(3)
x = 6/11
Answer:
x + 4y = 20
Step-by-step explanation:
Step 1: Subtract "x" on both sides.
x + 4y = 20
<u>-x -x</u>
Step 2: Simplify --> 4y = -x +20
Step 3: Divide 4 on all sides to leave "y" by itself. 4y = -(1)x + 20
4 4 4
Step 4: Simplify: y = -1/4x + 5
Answr: The Slope is "-1/4". The slope will always be the number in front of the "x".
