<h2>Answer:</h2>

y=\frac{1}{3}x+4

<h2>Explanation:</h2>

Slope-intercept form:

What the variables mean:

Y=the y axis

m=the slope

x=the x-axis

b=the y intercept (the point on the line that crosses the y-axis)

To Calculate the Slope:

1. Find any 2 points on the line

2. The number of units the second point is above the first is the numerator

3. The number of units the second point is to the right of the first is a denominator

(Please see the picture attached)

y=\frac{1}{3}x+b

To Find the Y-Intercept:

1. Find the point on the line that crosses the y-axis

(Please see the picture attached)

y=\frac{1}{3}x+4

If a triangle has a height of 14 inches and a base of 9 inches, what is area?
Ugo [173]

Answer:

The area of the triangle is A=63\ in^2

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=\frac{1}{2}(b)(h)

where

b is the base of triangle

h is the height of triangle

we have

b=9\ in\\h=14\ in

substitute in the formula

A=\frac{1}{2}(9)(14)

A=63\ in^2

Given f(x)=3x-2x^2 find f(3)
lilavasa [31]

Answer:

Step-by-step explanation:

Let's solve for f.

y=3x−2x2findf(3)

Step 1: Flip the equation.

−6df2inx2+3x=y

Step 2: Add -3x to both sides.

−6df2inx2+3x+−3x=y+−3x

−6df2inx2=−3x+y

Step 3: Divide both sides by -6dinx^2.

−6df2inx2

−6dinx2

=

−3x+y

−6dinx2

f2=

3x−y

6dinx2

Step 4: Take square root.

f=√

3x−y

6dinx2

or f=−√

3x−y

6dinx2

Answer:

f=√

3x−y

6dinx2

or f=−√

3x−y

6dinx2
