9. Two homebuilders are in the middle of installing windows on their homes. Tom uses the equation

y = 7x + 2 to model the number of windows he is installing on his home and Suzanne uses the equation

y = 6x + 5 to model the number of windows she is installing on her home. In each formula, x represents the number of days that Tom and Suzanne work on installing windows.


Who is working at a faster rate? How do you know?









Who started with the most windows already installed? How do you know?

Answers

Answer 1

Answer:

Hence, Suzanne is working at a faster rate.

Suzanne started with the most windows already installed

Step-by-step explanation:

Number of windows he's installing :

Tom's equation :

y = 7x + 2

Suzanne's equation :

y = 6x +5

x = number of days used

Let y = 10

Tom:

10 = 7x + 2

10 - 2 = 7x

8 = 7x

x = 8/7 ; x = 1.143

Suzanne :

y = 6x + 5

10 = 6x + 5

10 - 5 = 6x

5 = 6x

x = 5/6

x = 0.833

Since 0.833 < 1. 143

Hence, Suzanne is working at a faster rate.

Intercept in Suzanne's equation = 5

Intercept in Tom's equation = 5

Suzanne started with the most windows already installed

Answers

Answer:

4y^2-24y+36

Step-by-step explanation:

Expand the expression to simplify, which you do by using the FOIL method, then combining like terms.

(a-b)(a-b) = a^2 - 2ab + b^2

(2y-6)^2

= (2y-6)(2y-6)

can someone check behind me if both of these graphs have a slope of 3?

Answers

it looks like it is 5/3 for line E and 2/1 for line D.

Answer:

No. The slope of Line E is 3/2, and the slope of Line D is 6/8.

Step-by-step explanation:

For line E, let's find two points that the lines go through: (0,4) and (30, 24).

m=30-0/24-4

m=30/20

m= 3/2 or 1.5

Line E does not have a slope of 3.

Line D goes through these two points: (8,9) and (16,15).

m=15-9/16-8

m=6/8 or 0.75

Line D doesn't have a slope of 3.

Please help! What are the independent and dependent variables of this problem?

Answers

Answers:

Independent Variable = time = tDependent Variable = height = h(t)

======================================================

Explanation:

The horizontal axis always represents the independent variable. Often it is x, but in this case, it's t. The time value does not depend on the height. Time does it's own thing.

The height depends on the time value. The vertical axis, or y axis, is always representing the dependent variable. The notation h(t) helps us see that h must be paired with t, in order to find the value of h so to speak. As the time value changes, so does the height of the ball.

Solve for the variable
X-11 = 8

Answers

This is pretty easy to do.

First, you have to get x alone by getting rid of the terms next to it. In this case, it’s -11.

To get rid of a term, do the opposite.


So x - 11 + 11 = 8 + 11
Remember to do it on both sides.

x = 19
Answer: 19
Why?
You have to get x alone so you have to add 11 to both sides
X-11+11= 8+11
The 11 cancel out on the left and 8+11 equals 19 so x=19

The answer to this question is 9cm^2, the second answer

Step-by-step explanation:

To find the area of this parallelogram, you have to first find the area of one of the two triangles shown. The formula to solve a triangle is (base * height)/2, so that would be 4.5cm^2 for each triangle, times two for two triangles would be 9cm^2. If you wanted to do it an easier way, just multiply the length of the bottom of the parallelogram with the height. The measures telling you 3.5 are telling you the length of the diagonal line, so don't pay attention to that.

Heights of American adult women are normally distributed with mean 63.6 inches and standard deviation 2.5 inches. Find the height of an adult woman that corresponds to the 80th percentile.

Answers

Answer:

65.7

Step-by-step explanation:

Given ;

Mean, m = 63.6

Standard deviation, s = 2.5

80th percentile = 80 / 100 = 0.8

The Zscore corresponding to the 80th percentile ; Z < P = 0.842 (Z probability calculator)

Zscore = (x - m) / s

0.842 = (x - 63.6) / 2.5

0.842 * 2.5 = x - 63.6

2.105 = x - 63.6

x = 63.6 + 2.105

x = 65.705

Factor 16a + 72 to identify the equivalent expression

Answers

Hey there, thanks for posting your first question!

If you're asked to factor a polynomial, you need to look for the

greatest common factor between the terms that are involved.

The greatest common factor of 16a and 72 is 8 because 8

is the largest number that can divide into both 16 and 72.

The "a" doesn't qualify because it doesn't appear in every term.

So the 8 factors out.

When that happens, we are left with each term divided by that 8

inside a set of parenthses, I'll show you what I mean.

So we have 8(2a + 9).

I divided the 16a by the 8 and 72 by the 8 and if you

distribute it back you will end up with the original polynomial.

So our answer 8(2a + 9).

Grazing is a method of feeding in which herbivores, such as sheep, feed on plants. The intensity in which the herbivores in an ecosystem graze impacts the biodiversity of the plants in that ecosystem, as shown in the graph below. According to the graph, biodiversity is low during low grazing intensities. This is because only a few species of plants are able to outcompete the others and dominate the ecosystem. As the grazing intensity increases, the biodiversity increases because the dominant plant species are kept in check by the grazers. This allows the weaker competitors to grow. At very high grazing intensities the biodiversity decreases because only plants with adaptations to tolerate the effects of grazing are able to survive.Which of the following best explains how plant biodiversity would change if all of the grazers were suddenly removed from an ecosystem experiencing high intensity grazing? A. Plant biodiversity would likely decrease because every species of plant could grow without limitation after the herbivores were removed. B. Plant biodiversity would likely increase because removing one population from an ecosystem would allow more resources for all the others. C. Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others. D. Plant biodiversity would likely increase because only a few of the remaining plant species would be able to thrive without the herbivores.
