Write an equation of a line in slope intercept form that is parallel to y = 3x+6 and passes through the point (-10, 2.5)

TiliK225 [7]

1) Line should be parallel to y = 3x+6, so slope of this line should be =3.

y=mx +b

y=3x +b

Now we have to find b (y-intercept), using the point (-10, 2.5).

2.5 = 3*(-10)+b

b=2.5+30=32.5

y=3x + 32.5

2) The line should be perpendicular to y = -4x -2, so its slope is going to be negative reciprocal m= 1/4.

Now we have to find b (y-intercept), using the point (-16, -11).

y=(1/4)x +b

-11=(1/4)*(-16) + b

-11 = -4 +b

b = -7

y=(1/4)x - 7

If f(x) = 3x - 12, what is f(2)?<br>O A. -18<br>O B. -6<br>O c. 6<br>O D. 18

zhannawk [14.2K]

Replace x with 2:

f(x) = 3x -12:

f(2) = 3(2) - 12

= 6 - 12

= -6

Aaaaaa help I’m stuck at F I really need to do this so I could get a D please with explanation

Answer:

$1.51

Step-by-step explanation:

1.25 lb. of dried fruit : $\frac{\$1.84}{lb.}*\frac{1.25\ lb.}{1}=\$2.30$

0.5 lb. of cereal : $\frac{\$2.38}{lb.}*\frac{0.5\ lb.}{1}= \$1.19$

Cost = $2.30 + $1.19 = 3.49

Money = $5

$5 - $3.49 = $1.51 in change
