Mathematics
1 answer:
Alla [95]1 year ago
5 0

Answer:

Option D, 24

Step-by-step explanation:

<u>Step 1:  Determine the rate of change or slope</u>

m = \frac{y_2-y_1}{x_2-x_1}

m=\frac{32-8}{2-1}

m=\frac{24}{1}

m=24

Answer:  Option D, 24

What is the slope intercept from for 16x+9y=40
Doss [256]

Answer:

y =  (- \frac{16}{9})x +  \frac{40}{9}is the slope intercept form for 16x+9y=40

Step-by-step explanation:

Here, the given equation is 16 x +  9 y = 40

Now, the slope intercept form of an equation is y = mx + c,

here m = slope of the equation,  b  =  y - intercept

So, now 16x +  9y = 40 on simplification gives

9y  = 40 - 16x

or y = \frac{40 - 16x}{9}  = \frac{40}{9}   - \frac{16x}{9}

or, y =  (- \frac{16}{9})x +  \frac{40}{9}is the slope intercept form of the given equation.

Here, m = (-16/9) and y- intercept = 40/9

The linear function f(x) = 0.9x + 79 represents the average test score in your math class, where x is the number of the test tak
Levart [38]

Given:

The linear function for average test score in your math class is

f(x)=0.9x+79

where x is the number of the test taken.

The linear function g(x) in the given table represents the average test score in your science class, where x is the number of the test taken.

To find:

Part A: The test average for your math class after completing test 2.

Part B: The test average for your science class after completing test 2.

Part C: Which class had a higher average after completing test 4?

Solution:

Part A:

We have,

f(x)=0.9x+79

Put x=2 in the above function, to find the test average for your math class after completing test 2.

f(2)=0.9(2)+79

f(2)=1.8+79

f(2)=80.8

Therefore, the test average for your math class after completing test 2 is 80.8.

Part B:

From the given table it is clear that g(x) =79 at x=2.

Therefore, the test average for your science class after completing test 2 is 79.

Part C:

Put x=4 in f(x), to find the test average for your math class after completing test 4.

f(4)=0.9(4)+79

f(4)=3.6+79

f(4)=82.6

From the table it is clear that the value of g(x) is increased by 1 as x is increased by 1. So, the value of function g(x) at x=4 must be 1 more than 80.

g(4)=81

It is clear that,

82.6>81

Therefore, math class had a higher average after completing test 4.

Is there anything bigger than a ton
egoroff_w [7]

Answer:

No

Step-by-step explanation:

Well like how the ounce is the smallest a ton is the biggest.For example, it makes more sense to describe the weight of a human being in pounds rather than tons.
