Step 1

Let

x-------> represents the number of tubes of paint Catherine can buy

y------> the money to spend for a painting canvas

we know that

y> 20 ------> inequality A

y=54-8.5x ------> equation B

substitute equation B in inequality A

54-8.5x > 20

therefore

<u>the answer part a) is</u>

The inequality that best represents this scenario is 54-8.5x > 20

Step 2

Solve the inequality

54-8.5x > 20

54-20 >8.5x

34 >8.5x

34/8.5 >x

4 >x ---------> x < 4

therefore

<u>the answer Part b) is the option C</u>

less than 4

The answer is B. She is buying 4 paint tubes. 4 x 8.5 = 34. 34 - 20 = 14, which is less than 54.

Write the equation of the line that passes through (3, -2) and has a slope of 4 in point slope form
diamong [38]

y=mx+b is the equation of a line;

m=slope , b= y-intercept

m=4 ; so we have : y=4x+b

We are give a set of points which it passes through, we can simply plug them in:

-2 = 4(3)+b (3 is the x and -2 is the y)

We get -2 = 12 +b .... -14=b

our final equation is : y=4x-14
