Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2x² - x + 5
f(-3) = 2(-3)² - (-3) + 5
= 2(9) + 3 + 5
= 18 + 3 + 5
= 26
B 216 because if you multiply pi with the answer you get 678.58
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).
Step-by-step explanation:
To solve this question, we can represent variables for the length and width in two equations.

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:


Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

This tells us that the width could be either 50 or 30.
Substitute 50 into one of the equations to find the length:
2 (l) + 100 = 160
l = 30.
The length and width are 50 and 30 meters (or 30 and 50 meters).
She can purchase around 3 T-shirts because out of the $200, the ticket is $87.96 which leaves us left with $112.04. Each T-shirt is 30$. You just divide $112.04 by $30.
