NARA [144]

Answer:

13divided by 7

Step-by-step explanation:

$4x + 3x - 4 = 17 \\ 7x - 4 = 17 \\ 7x = 17 - 4 \\ 7x = 13 \\ \frac{7x}{7} = \frac{13}{7 } \\ x = \frac{13}{7} or1 \times \frac{6}{7}$

The equation of a circle is x^2 + (y - 10)^2 = 16. What is the radius and center?

gizmo_the_mogwai [7]

Answer:

Center = (0, -10)

Radius = 4 units

Step-by-step explanation:

$x^2 + (y - 10)^2 = 16\\(x-0)^2 + (y - 10)^2 = 4^2\\Equating\: it \: with\: \\(x-h)^2 + (y - k)^2 = r^2\\We\: find:\\-h = 0\implies h = 0\\-k = -10\implies k = 10\\Center = (-h,\:-k) \\Center = (0,\:-10) \\r^2 = 4^2\implies r = 4\\Radius = 4\:units$

Solve the following equation: 8x^2 = 2x

Rzqust [24]

Answer:

x = 0, x = $\frac{1}{4}$

Step-by-step explanation:

Given

8x² = 2x ( subtract 2x from both sides )

8x² - 2x = 0 ( factor out 2x from each term )

2x(4x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

4x - 1 = 0 ⇒ 4x = 1 ⇒ x = $\frac{1}{4}$
