Answer:

8x +4y

Step-by-step explanation:

6x + 3y + 2x + y

1) add similar variables together.

2) 6x + 2x = 8x

3y + (1)y = 4y.

3) y by itself basically means 1y, since in front of every variable theres an invisible 1.

Answer:

$4\frac{1}{4} - 2\frac{7}{8} = 1\frac{3}{8}$

Step-by-step explanation:

Given

$4\frac{1}{4} - 2\frac{7}{8}$ --- proper representation of the question

Required

Evaluate

Convert numbers to improper fractions

$4\frac{1}{4} - 2\frac{7}{8} = \frac{17}{4} - \frac{23}{8}$

Take LCM

$4\frac{1}{4} - 2\frac{7}{8} = \frac{34 - 23}{8}$

$4\frac{1}{4} - 2\frac{7}{8} = \frac{11}{8}$

Convert to improper fraction

$4\frac{1}{4} - 2\frac{7}{8} = 1\frac{3}{8}$

g(x) = 8x² + 9x − 7 ;

g(4) = 8(4²) + 9(4) − 7 ;

= 8(4*4) + 36 − 7 ;

= 8(16) + 36 − 7 ;

= 128 + 36 − 7 ;

= 164 − 7 ;

= 157 .

Answer:

yes

Step-by-step explanation:

youre trying to find when -1/4x + 3/2 = -x+ 3

so if you set it up like that and then solve for x you get 2

then, you know that 2 is your x value so just plug in x into one of the equations to get the y value

(i used -x+3 bc its easier)

-2+3=y

y= 1

so your solution is (2,1)

also heres the graph
