Lera25 [3.4K]

Answer:

im guessing 6 is your base and your height is 15 3/4.

Formula of a triangle we must remember:

BH x 1/2 (basically dividing by 2)

94.5 (fraction form will be: 94 1/2)

94.5 divided by 2 = 47.25 <---------- decimal form

94 1/2 divided by 2 = 47 1/4 <------- fraction form

The lengths of the sides of a triangle are x,x+1 and 7 centimeters and the perimeter of the triangle is 56 centimeters. The equa
____ [38]

Answer:

the longest side is 25

Step-by-step explanation:

the equation would be x+ x+1 + 7  for the 3 sides of the triangle

x + (x+1) + 7=56

combine like terms

2x+8 = 56

subtract 8 from each side

2x = 48

divide by 2

x = 24

the sides are

x=24

x+1 = 25

7

the longest side is 25

Question 7(Multiple Choice Worth 5 points)
Yuki888 [10]

Answer:

y = -3x

Step-by-step explanation:

Given

The attached graph

Required

Determine the graph equation

To do this, we pick any 3 corresponding points of x and y

(x_1,y_1) = (0,0)

(x_2,y_2) = (2,-6)

(x_3,y_3) = (-4,12)

The equation can then be solved using linear interpolation as follows:

\frac{y-y_3}{x-x_3} = \frac{y_2 - y_1}{x_2-x_1}

This gives:

\frac{y-12}{x-(-4)} = \frac{-6 -0}{2-0}

\frac{y-12}{x+4} = \frac{-6 -0}{2-0}

\frac{y-12}{x+4} = \frac{-6}{2}

\frac{y-12}{x+4} = -3

Multiply both sides by x + 4

(x + 4) * \frac{y-12}{x+4} = -3 * (x + 4)

y - 12 = -3 *(x + 4)

Open bracket

y - 12 = -3x -12

Add 12 to both sides

y - 12+12 = -3x -12+12

y = -3x
