Write an equation for the translation of x^2+y^2=25 by 7 units left and 2 units down

1 answer:

4 0

Your equation is a circle where the center is the origin (0, 0) and the radius is 5. With the translation, the new center is (- 7, - 2). Radius stays the same.

Your new equation is:

(x + 7)² + (y + 2)² = 25

What is the value of x

disa [49]

Answer:

x = 15 degrees

Step-by-step explanation:

This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.

$30+4x=90$

Now, we solve for x.

$-30+30+ 4x = -30+90$

$4x=60$

$\frac{4x}{4}=\frac{90}{4}$

$x=15$

If f(x) = -7x + 5x2 + 10, what does f(-2) equal?

Mkey [24]

F(x) = -7x + 5x² + 10

x = -2

substitute the x by its value

f(-2) = -7(-2) + 5(-2)² + 10
f(-2) = 14 + 5(4) + 10
f(-2) = 14 + 20 + 10
f(-2) = 44
