Find the sum of -8x^2+3 and -9x^2+3x-3

Answers

Answer 1

Answer:

-16x, and 3(x−28)

Step-by-step explanation:

-8x^2+3=-16,

Multiply 2 times −8.

which should get you −16x^2−1

Subtract 1 from 2, then you have −16x^1. For any term t, t ^1=t. so then it is -16x.

−9 ^2+3x−3

Calculate 9 to the power of 2 and get 81.

−81+3x−3

Subtract 3 from −81 to get −84.

=−84+3x

Find the equation in slope-intercept form that describes line.
A line through (-1, 1) and (2,3)

Answers

Answer:

y = 2/3 x + 5/3.

Step-by-step explanation:

Slope m = (3-1)/(2-(-1)) = 2/3.

y - y1 = m(x - x1)

y - 1 = 2/3(x - (-1))

y - 1 = 2/3(x + 1)

y - 1 = 2/3 x+ 2/3

y = 2/3 x + 5/3.

Answer:

no solution

Step-by-step explanation:

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7  ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

If Keenan makes a basket with 6 apples, what is the ratio of apples to oranges written as a fraction?

Answers

the answer i believe is 6:4

The ratio of apples to oranges, written as a fraction If Keenan makes a basket with 6 apples, is 5 / 4.

What is a fraction?

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.

Given:

For every 4 oranges, there are 5 apples,

Keenan makes a basket with 6 apples,

Calculate the number of oranges as shown below,

The number of oranges = 4 / 5 × 6 = 24 / 5

Calculate the fraction of apples to oranges as shown below,

Ratio = The total number of apples / The number of oranges

Ratio = 6 / 24 / 5

Ratio = 30 / 24

Ratio = 5 / 4

Thus, the ratio is 5 / 4.
