Intersecting the x axis means y is 0
plug y=0 in the equation and solve for x to see if there are real solutions
x^2-10x+0+0=-30
x^2-10x+30=0
this cannot be factored, so let's see if b^2-4ac is bigger than 0
10^2-4*1*30=-20
so the solutions for this equation are not real numbers, therefore the answer is no.

Answer:
<u>If the amount is P, with the interest rate of 12%, the interest over the year is:</u>
<u>In this case the quarterly interest rate is:</u>
<u>With the same amount and 3% quarterly rate, the yearly interest would be:</u>
<u>The quarterly interest rate in this case is:</u>
If the quarterly interest rate is r, it should be little less than 3% to yield a 12% yearly rate.
So Kraig is wrong.
77 - 2 = 75
75 ÷ 5 = 15
The number is 15.
Hope this helped!
Answer:
Diane had 0.3 grams of pepper left
Step-by-step explanation:
If she had 0.9 grams of pepper, we can subtract the amount of pepper she used (0.6) to find out how much she has left.
0.9 - 0.6 = 0.3
(sorry if this is confusing but I hope it helped)
