Answer:
x = 0, Need the steps?
STEPS:
9x - 7 = -7 (Original Problem)
9x = 0 (Add 7 to both sides)
x = 0 (Divide both sides by 9)
It's is a square and you know just by graphing it
Answer:
The numbers 1 to 12 must be placed in the circles of the star shown on the right. The sums of the numbers in each row, and the sum of the numbers in the six outer circles of the star, must be equal to 26. Arrange the numbers accordingly.
Answer:

Step-by-step explanation:
Line g passes through (-2,6) and (-3,2).
The slope of line g is given by:

Let's substitute the values to get:

The equation that is perpendicular to line g will have a slope that is the negative reciprocal of 4.
i.e -1/4
If this line passes through (P,Q), then the equation is:

You just multiple my guy. 2:3 is like 2/3. What is 2/3 of 39
39*2/3 = 26
