Solve the quadratic equation below for the exact values of x:<br> 4x^2-5=75
grandymaker [24]

Step-by-step explanation:

4 {x}^{2}  - 5 = 75 \\ 4 {x}^{2}  = 75 + 5 \\ 4 {x}^{2}  = 80 \\  {x}^{2}  =  \frac{80}{4}  \\  {x}^{2}  = 20 \\ x = \pm \sqrt{20}  \\ x = \pm 2 \sqrt{5}

Y= 4/5 x-7 what are the y and x intercepts?
solmaris [256]

The x intercept is (8.75, 0) and y - intercept is (0, -7)

<em><u>Solution:</u></em>

Given that we have to find the x and y intercepts

Given equation is:

y = \frac{4}{5}x - 7

The x intercept is the point where the line crosses the x axis

The y intercept is the point where the line crosses the y axis

<em><u>Finding x - intercept:</u></em>

To find the x-intercept of a given equation, plug in 0 for 'y' and solve for 'x'

Substitute y = 0 in given equation

0 = \frac{4}{5}x - 7\\\\\frac{4x}{5} = 7\\\\4x = 35\\\\x = \frac{35}{4} = 8.75

Thus x intercept is (8.75, 0)

<em><u>Finding y - intercept:</u></em>

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

Substitute x = 0 in given equation

y = \frac{4}{5} \times 0 - 7\\\\y = 0 - 7\\\\y = -7

Thus y - intercept is (0, -7)
