-a^2+7b^4-2c^3
-(-4)^2+7(-2)^4-2(-3)^3
= -(16)+7(16)-2(27)
= -16+112-54
=-70+112

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6? Drag each choice into t

sesenic [268]

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?

Parallel, slope is the same, perpendicular slope is opposite and reciprocal

line n, with slope −6 , same slope -----> Parallel

line p, with slope 1/6 , opposite and reciprocal -----> Perpendicular

line q, with slope −1/6 , -----> Neither

line m, with slope 6, -----> Neither

The baker pays $0.80 per pound for sugar and $1.25 per pound for butter. Write an expression that shows how much the baker will

alekssr [168]

X is sugar
y is butter
z is total money

$0.80x + $1.25y = z

the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

Graph the line passing through the given point and having the indicated slope. through (3, negative 2) with slope minus−three

Alex17521 [72]

Answer:

See the attachment

Step-by-step explanation:

A slope of -3/5 means the line drops 3 units for each 5 units it goes to the right. Then you can find another point on the line by going 5 uints to the left (to x=-2) and 3 units up (to y=1).

Plot the given point and the one just computed and draw the line through them.
