What is the base of a triangle with an area of 30 square inches and height of 10 inches.

Base = 6 inches

Step-by-step explanation:

30 divided by 1/2 equals 60. 60 divided by 10 equals 6.

To check:

A = 1/2bh

30 = 1/2 x 6 x 10

30 = 30 ✅

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
