Write a linear equation that goes through the points (0,4) and (4,10). A. y =3⁄2x + 4 B. y =3⁄2x – 4 C. y =2⁄3x – 4 D. y =2⁄3x +
Elena L [17]

Answer:

A

Step-by-step explanation:

To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.

\frac{y_2-y_1}{x_2-x_1} = \frac{10-4}{4-0}=\frac{6}{4}=\frac{3}{2}

Write the equation using the slope m=3/2 and the point slope form.

y-y_1=m(x-x_1)\\y-10=\frac{3}{2}(x-4)

This is the equation of the line. You can convert it to slope intercept form:

y-10=\frac{3}{2}(x-4)\\y-10 = \frac{3}{2}x - 6\\y=\frac{3}{2}x +4

The base of a triangle is 7 inches more than 4 times the height. If the area of the triangle is 93 square inches, find the base
Galina-37 [17]

Answer:

Step-by-step explanation:

Let the height = h

Let the base = 4h + 7

Area of a triangle = 1/2 * b * h

Area = 93 square inches

1/2 * (4h + 7)* h = 93            Multiply both sides by 2

(4h + 7) * h = 93*2

(4h + 7)*h = 186                    Remove the brackets

4h^2 + 7h = 186                   Subtract 186 from both sides.

4h^2 + 7h - 186 = 0

Use the quadratic formula to solve

a = 4

b = 7

c = - 186

x1 = (-7 + sqrt(7^2 - 4*4*(-186) ) /2*4

x1 = (-7 + sqrt(49 - 16*(-186)) / 8

x1 = (-7 + sqrt(49 + 2976)) / 8

x1 = (-7 + sqrt(3025)) / 8

x1 = (-7 +55 ) / 8

x1 = (48)/8

x1 = 6

There is another root, but it has to be minus and therefore cannot be used as a length. x2 = - 7.75

h = 6

b = 4*6 + 7 = 31

Check

Area = 1/2 * b * h

Area = 1/2 * 31 * 6

Area = 1/2 *186

Area = 93 which is what we were given so the answer is correct.
