Answer:

d. a = 39

Step-by-step explanation:

Question:

for which value of "a" will the trinomial be factorizable.

x^2+ax-40

For the expression to have integer factors, a = sum of the pairs of factors of -40.

-40 has following pairs of factors

{(1,-40), (2,-20, (4,-10), (5,-8), (8, -5), (10,-4), (20,-2), (40,-1) }

meaning that the possible values of a are

+/- 39, +/- 18, +/- 6, +/- 3

out of which only +39 appears on answer d. a=39

Ket [755]

Answer:

$\sf 2 \frac14 \ cups$

Step-by-step explanation:

Add the amounts together:

$\sf \implies \dfrac24+1+\dfrac34$

Convert the whole number 1 into a fraction with denominator 4:

$\sf \implies \dfrac24+\dfrac44+\dfrac34$

As all the denominators are the same, we can simply add the numerators:

$\sf \implies \dfrac{2+4+3}4$

$\sf \implies \dfrac94$

Finally, convert the improper fraction into a mixed number:

$\sf \implies 2 \frac14 \ cups$

How to find slope using a graph. <br>

Pani-rosa [81]

Answer:

See below.

Step-by-step explanation:

Find two points on the graph that are easy to read.

Start at one point. You must now go to the other point, but you can only move vertically (up and down) and horizontally (right and left.)

Move vertically toward the other point. Count the number of units you moved. Up is positive, and down is negative. This is the rise.

Now move horizontally to the second point and count the units. Right is positive and left is negative. This is the run.

slope = rise/run
