How do i do substitution if x is on the same side as y

1 answer:

5 0

Cancel out one kind of variable from that side and put it on the other side.

Examples:

5x + 5y = 15
---- - 5y ------- - 5y

5x = 15 - 5y

6c - 2b = 48
---- +2b -------- + 2b

6c = 48 + 2b

Hope this helps!

A line with a slope of 3 passes through the points (-8,f) and (-9,7). What is the value of f

larisa [96]

Answer:

Step-by-step explanation:

Slope can be calculated by:

$m = \frac{y_2-y_1}{x_2-x_1}$

We know M, y1, x2, and x1. We want to calculate for y2

$\frac{f-7}{-8-(-9)} = 3\\\frac{f-7}{1} = 3\\f-7 = 3\\f = 10\\$

Find an equation of the circle having the given center and radius.<br> Center ( - 1, 1), radius 7

suter [353]

Answer:

(x+1)^2 + (y+1)^2 = 49

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x- -1)^2 + (y- -1)^2 = 7^2

Simplifying

(x+1)^2 + (y+1)^2 = 49
