Multiply. (x - 7)(x - 10) A) 2x + 70 B) x2 + 70 C) x2 - 70 D) x2 - 17x + 70

1 answer:

3 0

The answer is D. The easiest way to see this is by using the FOIL method.
First
Outside
Inside
Last. So the first is x2, the outside is -10x, the inside is -7x, and the last is 70. So it would be x2-17x+70

What is the equation of the line graphed below?

andrew-mc [135]

Answer: $y=-\frac{1}{3}x$

Step-by-step explanation:

From the origin we can see to get to the point plotted we have to go down 1 and right three giving us the slope $\frac{-1}{3}$

These are in the form of y=mx+b

b is the y-intercept and m is the slope

since the y-intercept is 0 b is 0 and isn't need leaving us with y=mx

We can put our slope into the equation giving us the answer in C

Lyrx [107]

Answer:

133.45

Step-by-step explanation:

They are looking for arc length. The formula is

$\frac{n}{360}$ * 2πr

a quarter circle is 90°, so put 90 for n. 85 is the radius, so put that for r.

$\frac{90}{360}$ * 2 π (85)

Your computer supply store sells two types of inkjet printers. The first, type A, costs $269 and you make a $24 profit on each o

just olya [345]

This is the concept of applications of linear equations; suppose you need x number of type A and y number of type be to make the profits required;
Total number of printers will be:
x+y=120....i
Total amount made will be:
24x+18y=2340....ii
thus solving equations i and ii by substitution we shall have:
x+y=120
x=120-y
thus substituting the above in equation ii we get:
24(120-y)+18y=2340
2880-24y+18y=2340
putting like terms together we get
-24y+18y=2340-2880
540=6y
thus
y=540/2
y=90
hence;
x=120-90=30
Therefore to make the profit of $2340 you must sale 90 type A printers and 30 type B printers
