Answer:

Step-by-step explanation:

(4, -8) and (-1, 3), formula used will be $y_{1}-y_{2}$ / $x_{1} -x_{2}$ so:

-1 - (-8)/3 - 4 = -1 + 8/1 = 7/1 = 7

i edited my answer a few times cause i read the points wrongly so just know that this is the correct one.

F(X)=-2x-3 g(X)=3X+1 find (fxg)(X)

Goshia [24]

Answer:

6x² - 7x - 3

Step-by-step explanation:

(f × g)(x) = f(x) × g(x), that is

(2x - 3)(3x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(3x + 1) - 3(3x + 1) ← distribute both parenthesis

= 6x² + 2x - 9x - 3 ← collect like terms

= 6x² - 7x - 3

Why does 10x-1=10x+4 has no solution

Jlenok [28]

Answer:

Simplifying

10x + 1 = 10x + -4

Reorder the terms:

1 + 10x = 10x + -4

Reorder the terms:

1 + 10x = -4 + 10x

Add '-10x' to each side of the equation.

1 + 10x + -10x = -4 + 10x + -10x

Combine like terms: 10x + -10x = 0

1 + 0 = -4 + 10x + -10x

1 = -4 + 10x + -10x

Combine like terms: 10x + -10x = 0

1 = -4 + 0

1 = -4

Solving

1 = -4

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Find the diameter of the circle with the given circumference. Use 3.14 for π(PI).

disa [49]

Answer:

Diameter = 8.28

Step-by-step explanation:

Step 1: Solve for r

2*3.14*r = 26 / 2

3.14r / 3.14 = 13 / 3.14

r = 4.14

Step 2: Find the diameter by multiplying the radius by 2

r = 4.14

d = 4.14 * 2

d = 8.28

Answer: Diameter = 8.28
