Please help me find the equation it so hard
nataly862011 [7]

Answer:

y = 4/5x + 3/5  

Step-by-step explanation:

In the slope-intercept form, y = mx + b, we need to find the values of the slope (m) and the y-intercept.

Using points (-7, -5) and (3, 3), we can calculate for the slope of the equation given the formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (-7, -5)

and (x2, y2) = (3, 3).

Plug the given values into the slope formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{3 - (-5)}{3 - (-7)} = \frac{3 + 5}{3 + 7} = \frac{8}{10} = \frac{4}{5}

Therefore, the slope of the line is 4/5.  

Next, we need to find out the value of the y-intercept (b).

We can use one of the given points, (3, 3), along with the slope (4/5) to solve for the y-intercept:

y = mx + b

3 = 4/5(3) + b

3 = 12/5 + b

Subtract 12/5 from both sides:

3 - 12/5 = 12/5 - 12/5 + b

3/5 (or 0.6) = b

Therefore, the y-intercept is 3/5.

We can now establish our linear equation as:

y = 4/5x + 3/5

The tile along the edge of a triangular community pool needs to be replaced. A right triangles, where the hypotenuse is labeled
Anastaziya [24]

Answer:

C. 12x² + 8x + 25

Step-by-step explanation:

A. 12x² + 15

B. 20x² + 25

C. 12x² + 8x + 25

D. 24x² + 16x + 50

Hypotenuse = 8x²

Height = 4x² + 15

Base = 8x + 10

Perimeter of the triangle = hypotenuse + height + base

= 8x² + (4x² + 15) + (8x + 10)

= 8x² + 4x² + 15 + 8x + 10

Perimeter of the triangle = 12x² + 8x + 25

C. 12x² + 8x + 25

What are the solutions to the system?
Klio2033 [76]
Y = x² + 2x – 45
y = -3x + 5

-3x + 5 = x² + 2x – 45
x² + 5x – 50 = 0
x has two values 5 and -10
x = 5 => y = -10
x = -10 => y = 35

Good luck.
