Answer:
C 89a + 2c)
Step-by-step explanation:
The largest factor of both 8 and 16 is 8. So, 8 = GCF
factor out an 8 and you get 8(a + 2c)
To check if you are correct, multiply and see if you get what you started with.
10r² + 3 = 813
10r² = 813 - 3
10r² = 810
r² = 810 ÷ 10
r² = 81
r = √81
r = <u>9</u>
So, the value of <em>r </em>is 9

Answer:
Linear equation: x = -1
Step-by-step explanation:
Vertical lines have undefined slopes, as represented by the linear equation, <em>x = a, </em>where the x-intercept is (a, 0).
A vertical line has <em>undefined</em> slope because all points the line have the same x-coordinate. Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as a finite number. The equation cannot be expressed in slope-intercept form because it has an undefined slope.
Therefore, since you're given the point, (-1, 4), then it means that your equation will be: x = -1.
