Answer:

x $\geq$ 4

Step-by-step explanation:

4x^2 - 64 $\geq$ 0 ; move 64 over

4x^2 $\geq$ 64 ; divide by 4

x^2 $\geq$ 16 ; take square root of both sides

x $\geq$ 4

ANSWER

The correct answer is C

EXPLANATION

We want to find the quotient:

$- \frac{10}{19} \div ( - \frac{5}{7} )$

We multiply by the reciprocal of the second fraction:

$- \frac{10}{19} \times ( - \frac{7}{5} )$

We cancel out the common factors to obtain:

$- \frac{2}{19} \times ( - \frac{7}{1} )$

We multiply to get

$\frac{ - 2 \times - 7}{19 \times 1}$

This simplifies to :

$\frac{14}{19}$

The correct answer is C

What is the solution to 10y=5x+10

mixas84 [53]

The slope intercept form of that equation would be y = 1/2x + 1. 1 would be the y-intercept, and 1/2 would be the slope. If you are looking for the answers to y and x, you would need another equation containing those variables to figure that out.
