Answer:
77.77 or 78%
Step-by-step explanation:
She got 35/45 so
35 divided by 45 is 0.777777778
0.777777778 x 100 = 77.7777778
77.77% or 78%
Answer:
8x^2 + 5y + 1
Step-by-step explanation:
1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y
group like terms
= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 5y + 1 - 3 + 3
= 8x^2 + 5y + 1
add them both then you get the awnser if the four is not a negative. if the four is a negative use division.
To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5
The answer is 0 because it isn't above 49 and therefore can't be rounded to 100.
Hope this helps :)
