Sam the Hummingbird flies at a rate of 2 yards per minute, as modeled by the equation y = 2x. She
daser333 [38]

Answer:

See attachment for plot

Step-by-step explanation:

Given

y =2x

R =+2 --- increment in the rate

First, we need to model the new rate

A linear equation is:

y = mx + b

Where

m = rate

Compare y =2x and y = mx + b. we have:

m =2

The above represents the previous rate.

The new rate:

R =+2

Rewrite as:

R = m+2

R = 2+2

R = 4

So, the model is:

y = Rx

y = 4x

<u>The plot at 1 and 2 minutes</u>

When x = 1

y = 4x = 4 * 1 = 4

When x = 2

y = 4x = 4 * 2 = 8

So, we have:

(x_1,y_1) =(1,4)

(x_2,y_2) =(2,8)

<em>Whether she moves backwards or forward, the distance covered remains the same</em>

the ratio of red marbles to blue marbles in a bag is 3:4. if there are 42 marbles in the bag, how many of the marbles are red?
AlexFokin [52]

Answer:

18

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 = 7

Divide the amount of marbles by 7 to find the value of one part of the ratio

42 ÷ 7 = 6 ← value of 1 part of the ratio, thus

red marbles = 3 × 6 = 18
