Marysya12 [62]

Answer:

210 candy bars

85 gum

Step-by-step explanation:

$200=0.75cb+0.50gum

cb+gum=295

gum=295-cb

substitute

$200=0.75cb+0.50(295-cb)

$200=0.75cb+147.5-0.50cb

$200=0.25cb+147.5

0.25cb=52.5

cb=210

gum=295-210=85

Find the equation of the straight line passing through the points (-1,3) and (1,9).

Lena [83]

Answer:

The equation of the straight line is $y=3x+6$

Step-by-step explanation:

Any straight line passing through points $(a_1,b_1)$ and $(a_2,b_2)$ is given by:

$y-b_1=m(x-a_1)$ where m is defined as the slope of the line:

$m=\frac{b_2-b_1}{a_2-a_1}$

In the given question

$m=\frac{9-3}{1-(-1)} =3$

Substituting the values we get:
