Answer:

3ax−11a−9x

Step-by-step explanation:

3ax+4a−(9x+15a)

Distribute the Negative Sign:

=3ax+4a+−1(9x+15a)

=3ax+4a+−1(9x)+−1(15a)

=3ax+4a+−9x+−15a

Combine Like Terms:

=3ax+4a+−9x+−15a

=(3ax)+(4a+−15a)+(−9x)

=3ax+−11a+−9x

OLga [1]

Answer:

Notebook = $2.75

Pencil = $1.25

Markers = $ 0.50

Step-by-step explanation:

Stan:

n + 3p + 2m = 7.5

Jan:

2n  + 6p + 5m = 15.50

Fran:

n + 2p + 2m = 6.25

Stan - Fran:

p = 1.25

Lets replace p with 1.25

n + 3(1.25)  + 2m  = 7.5

2n + 6(1.25) + 5m = 15.50

n + 2(1.25) + 2m = 6.25

Simplify

n + 3.75 + 2m = 7.5

2n + 7.5  + 5m = 15.50

n + 2.50 + 2m = 6.25

n + 2m = 3.75     stan

2n + 5m = 8       jan

n + 2m = 3.75     fran

stan = fran

jan - 2(stan)

m = 0.5

n = 2.75

at least one y-intercept  - where it crosses the y axis- they both have at least one

an oblique asymptote  or slant asymptote- when the degree of the polynomial in the numerator is higher than the denominator - this is true

a vertical asymptote  - they both have a vertical asymptote

Simplify the following expression
shepuryov [24]
The Answer would be 2.8 because when you subtract -16 - 8 you get -24... then you divide that by 2 and you should have -12 + 25 / 5 + 1.... from there you can move the one from the end and add it to 25 and you get -12 + 26 / 5.... and all you have to do is simple math there... -12 + 26 = 14... and 14 / 5 == 2.8

ANSWER == 2.8

Hope that Helped

Solve the system of linear equations by graphing. y = –5/2x – 7 x + 2y = 4 What is the solution to the system of linear equation
muminat

ANSWER

(–4.5, 4.25)

EXPLANATION

The first equation is

y =  -  \frac{5}{2}x - 7

This function is in the slope-intercept form

The second equation is:

x + 2y = 4

2y =-x+ 4

y =  -  \frac{1}{2}x + 2

The graph of the two functions are shown in the attachment.

The point of intersection represents the solution to the system of equations they represent.

The solution is

(–4.5, 4.25)
