Answer:
B
Step-by-step explanation:
For quadratic expression in this form, the first step is to multiply the number in front of
with the last term, the constant (with the sign in front as well). This is the "multiplied number".
Step 2 is to come up with 2 numbers which when multiplied is equal to the "multiplied number" in step 1 above and also add to the number in front of
.
For this problem, we would need 2 numbers that
- Add up to 27, and
- When multiplied, comes to -90 <em>(18 * -5 = -90)</em>
They already found the 2 numbers as expressed in the form shown
. The 2 numbers are +32 and -5.
<em><u>Do they add up to 27, as required?</u></em>
Yes, 32-5=27
<u><em>Do they come to -90 when multiplied?</em></u>
No, 32 * -5 = -160
Hence, they add up, BUT NOT multiplied.
So the answer choice B is right.
Answer:
100x +150y ≤ 1200
Step-by-step explanation:
The amount Isabel will spend on 5 oz cups is 100x. The amount she will spend on 8 oz cups is 150x. In order to stay within her budget she must have the total be less than or equal to the budget amount:
