Answer:

Use the two points of a linear function to write an equation in slope-intercept form by first finding the slope of the function, and then using a point and the slope to determine the y-intercept. Write the equations in slope-intercept form.

An artist wants to frame a square painting with an area of 400 square inches she wants to know the lenth of the wood trim that i

Jet001 [13]

Answer:

The formula for the area of a square with sides of length x is A = x2 so

x2 = 400 is the equation

This equation has 2 solutions, namely x = ±√400 = +20 or -20

The negative solution does not make sense because a length cannot be less than 0.

The total length needed to go around the painting is the perimeter of the square, which is

P = 4*x = 4*20 = 80 inches

I need help setting up this problem. Please help me out.

Ilia_Sergeevich [38]

Answer:

12 pounds

Step-by-step explanation:

One quantity is asked for, so it is convenient to let a variable represent that. We can use x to represent pounds of chocolate. Then the total cost of the mix is ...

19.30·x + 3.50·18 = 9.82·(x +18) . . . . cost of chocolate + cost of trail mix

9.48·x = 113.76 . . . . . . simplify, subtract 63+9.82x

113.76/9.48 = x = 12 . . . . . . divide by the coefficient of x

The owner needs to mix 12 pounds of chocolate. (no rounding necessary)

Which number line shows the solution to the inequality? y - 2 < -5

Tatiana [17]

For this case we have the following inequality:
$y - 2 \ \textless \ -5
$
We will solve the inequality algebraically.
We have then:
We add 2 to both sides of the inequality:
$y - 2 + 2 \ \textless \ -5 + 2
$
Rewriting we have:
$y \ \textless \ - 3
$
Therefore the solution is:
(-inf, -3)
Answer:
(-inf, -3)
See attached image.
