Hi Brainly users! I have an 8th grade math problem for you. 15 points plus Brainiest for the person with the most helpful answer

RUDIKE [14]

Answer:

The answer is D. 14

Step-by-step explanation:

If you were to plug in 14 for x, it would look something like this:

$\frac{14-4}{14}$ = $\frac{5}{7}$

Solve 14-4

$\frac{10\\}{14}$ = $\frac{5}{7}$

if you were to multiply 5 and 7 by 2, you would get

$\frac{10}{14}$ .

This makes the equation true, because

10/14 does equal itself (10/14)

Have a nice day!

How do you find the value of t in -t/7=1/15

kolezko [41]

First, multiply the 7 on both sides.
$\frac{-t}{7} = \frac{1}{15}$
$-t = \frac{7}{15}$
Finally divide by -1 on both sides to get t = -7/15 as your answer.

What are the coordinates of the x-intercepts of the parabola y = x² - 8x + 15?

tamaranim1 [39]

Answer:

(3, 0) and (5, 0)

Step-by-step explanation:

we have

$y=x^{2}-8x+15$

we know that

The x-intercepts are the values of x when the value of y is equal to zero

For y=0

$x^{2}-8x+15=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-8x+15=0$

$a=1\\b=-8\\c=15$

substitute in the formula

$x=\frac{-(-8)\pm\sqrt{-8^{2}-4(1)(15)}} {2(1)}$

$x=\frac{8\pm\sqrt{4}} {2}$

$x=\frac{8\pm2} {2}$

$x=\frac{8+2} {2}=5$

$x=\frac{8-2} {2}=3$

x=3, x=5

therefore

The x-intercepts are (3,0) and (5,0)
