What is the coefficient of y in the expression 2 ⋅ 4 + 3y?

2 answers:

5 0

A coefficient is the number that is multiplied by the variable (the letter).
so the coefficient in ur expression is 3.

the 2 and the 4 are constants...because they are numbers with no variables

3 Is your coefficient because what ever in front of your variable is your coefficient

Step-by-step explanation:

step 1

Find out the total ball bearing ordered

Multiply the number of ball bearing boxes by the number of ball bearings in each box.

$17(85)=1,445\ ball\ bearings$

step 2

Find out the total springs ordered

Multiply the number of spring boxes by the number of springs in each box.

$15(90)=1,350\ springs$

step 3

To find out how many more ball bearings than springs did they order, subtract the total number of springs from the total number of ball bearings

$1,445-1,350=95$

A hot air balloon went from an elevation of 5,038 feet to an elevation of 3,403 feet in 30 minutes. What was its rate of descent

jeyben [28]

Answer:

Step-by-step explanation:

In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.

That means that the balloon traveled downward 62.5 feet every minute.

Answer:

Transformation include reflecting and dilating of points

The scale factor from PQR to P'Q'R' is 1/4

The coordinates of P"Q"R" are P"=(-1,0) Q"=(0,-1) R"=(2,-1) .

PQR and P′'Q′'R′' are not congruent

The points are given as:

p=(4,0)

q=(0,-4)

r=(-8,-4)

p'=(1,0)

q'=(0-1)

r'=(-2,-1)

(a)The scale factor from PQR to P'Q'R

To do this, we make use of corresponding sides QR and Q'R

So, the scale factor (k) is:

k=q'r'/qr

k=2/8

k=1/4

(b) The coordinates of P"Q"R from reflecting P'Q'R' about the y-axis

The rule of this transformation is:

(x,y)--------(-x,y)

So, we have:

p"=(-1,0)

q"=(0,-1)

r"=(2,-1)

No they are not

This is so because

PQR was dilated by 1/4 to get P'Q'R

P'Q'R' and P"Q"R" are congruent

Hence, PQR and P′'Q′'R′' are not congruent
