Hey Brion,
1) <span>Evaluate 2A - 3B for A = 7 and B = -2.
To solve this start by filling in the variables.
2(7) - 3(-2)
Now multiply, remember that a positive times a negative is a negative.
14 - (-6)
Finally, subtract. Remember, Keep, Change, Change (KCC). Keep the first number, change symbol (for subtraction use addition), and change the negative number to a positive number.
14 + 6 = 20
</span><span>2) If x = -3, then x 2-7x + 10 equals
Start by filling in the variables.
-3(2) - 7(-3) + 10
Now follow PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction) to solve. Remember K.C.C (no. 1 above)
</span>-3(2) - 7(-3) + 10
<span>(-6) - (-21) + 10
(-6) + (21) + 10
15 + 10
25*****See NOTE!***
</span><span>_____________________________________________________________
Note: For #2 you may be missing a symbol between the first "x" and "2" because the answer I got above (25) is not one of your choices. Let me know what symbol is missing in the equation: </span><span>x 2-7x + 10, and I will help you solve it.</span>
Well the answer couldn’t be C because the arrow has to go to the right not left because for the > in the equation
So the answer has to be D because the dot it on -.5 and the arrow is going right
Answer:
<h2>A</h2><h2 />
Step-by-step explanation:
m (slope) =<u> rise </u> = <u> y </u> = <u> y₁ - y₁ </u>
run x x₁ - x₁
to get y = mx
therefore, the answer to the question is :
A. The slope m is rise over run, so y over x =m.
Solve for y to get y=mx.
Answer:
Have a great day
Step-by-step explanation:
=3 1/2÷1/4
=7/2×4
=7×2
=14
It is 20% because it is 20 out of 60%
