Answer:
Step 2
Step-by-step explanation:
Fiona did mistake step 2.
Use the distributive property to multiply -3 times each term in the trinomial.
The correct result is
-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21
Fiona written -6x instead of + 6x.
That's the error.
The answer is "Step 2"
Hope you will understand the concept.
Thank you.
Step-by-step explanation:
John has borrowed $6.50 from his friends and $11.75 from his sister. To find how much money he needs to repay you can just add up the amount of money he has borrowed.
Make an equation to solve for this, where x = amount of money John needs to repay. Make the amount of money John borrowed add up to x. Your equation should look like:
$6.50 + $11.75 = x
Combine like terms (add 6.50 and 11.75).
$18.25 = x
After solving the equation, you have figured out that John need to repay $18.25 in total.

Answer:</h2>
By process of elimination, we can eliminate:
- <em>A:</em> <em>y = 3x - 1</em>
- <em>C: y = 3x + 1</em>
- <em>B: y = -3x</em>
<em>A and C</em> don't work because the given line has it's y-intercept at the origin, therefore, no y-intercept is written. <em>B </em>is not it either because the line <em>does not</em> go <em>down</em> from <em>left to right</em>, therefore, the slope is <em>not</em> negative.
The answer is <em>D: y = 3x</em> because since the line goes <em>up</em> from <em>left to right</em>, the slope is positive, and the y-intercept is the origin, so the equation will have no b.
