Let fat be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 121 + 1.42x?
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
The amount of calories in a cheeseburger increases by 121 for every one gram of fat. The calorie amount estimated by this model is 1.42 if there are zero grams of fat.
The amount of fat in a cheeseburger increases by 121 grams for every one calorie.
The fat amount estimated by this model is 1.42 grams if there are zero calories.
The amount of fat in a cheeseburger increases by 1.42 grams for every one calorie.
The fat amount estimated by this model is 121 grams if there are zero calories.
The amount of calories in a cheeseburger increases by 1.42 when there are zero grams of fat.
The calorie amount estimated by this model is 121 if there is one gram of fat.
Using linear function concepts, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which represents by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The explanatory variable fat is the input.The response variable calories is the output.The equation is:
[tex]y = 121 + 1.42x[/tex]
The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

Part (i)
I'll use H in place of T to represent the heat of the object. That way there isn't a clash of variables lowercase t vs uppercase T.
The equation we're working with is updated to:
H(t) = 22 + a*2^(bt)
Plugging in t = 0 as the initial time value should lead to the temperature being H = 86 degrees Celsius.
So,
H(t) = 22 + a*2^(bt)
86 = 22 + a*2^(b*0)
86 = 22 + a*2^0
86 = 22 + a*1
86 = 22 + a
a+22 = 86
a = 86-22
a = 64
Answer: 64=====================================================
Part (ii)
We'll use the value of 'a' we found earlier. Plus we'll use the fact that H = 28 when t = 0.5 (since 30 min = 30/60 = 0.5 hr).
H(t) = 22 + a*2^(bt)
28 = 22 + 64*2^(b*0.5)
28-22 = 64*2^(0.5b)
64*2^(0.5b) = 6
2^6*2^(0.5b) = 6
2^(6+0.5b) = 6
log( 2^(6+0.5b) ) = log(6)
(6+0.5b)*log(2) = log(6)
6+0.5b = log(6)/log(2)
6+0.5b = 2.5849625
0.5b = 2.5849625-6
0.5b = -3.4150375
b = -3.4150375/(0.5)
b = -6.830075

Complete the sentences to explain how the model on the number line could be used to find the answer. Starting at 0 move twice to the left______ spaces. 2 • (–5) = ______. The answer is the opposite of that value, ______ .
Answer:
Starting at 0 move twice to the left___5___ spaces. 2 • (–5) = ___-10___. The answer is the opposite of that value, ___10___ .
Step-by-step explanation:
The required blank space is filled by the numbers, 5, -10, and 10.
Given that,
Starting at 0 move twice to the left______ spaces. 2 • (–5) = ______. The answer is the opposite of that value, ______ . To determine the solutions for the blank spaces.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
here,
The number line 2(-5), shows that move twice to the left 5 spaces.
And This results in -10 spaces having to move, and the outcome is the opposite of the number 10.
Thus, A complete solution is "Starting at 0 move twice to the left 5 spaces. 2 • (–5) = -10. The answer is the opposite of that value, 10.

no silly answers please
Answer:
Step-by-step explanation:
If x=9, then x^2=81, because 9*9=81. -x^2=81, because -9*-9=81, and (-x)^2=81, because -9*-9=81.
If x=6, then x^2=36, because 6*6=36. -x^2=36, because -6*-6=36, and (-x)^2=36, because -6*-6=36.
Answer:
Keep in mind that x has a coefficient of 1.
x = 9x² = 9² = 81
-x² = - 1 · 9² = -1 · 81 = -81
(-x)² = (-9)² = 81
x = -6x² = -6² = -36
-x² = - 1 · -6² = -1 · 36 = -36
(-x)² = (-1 · -6)² = 36

The total cost after sales tax to fix Azar’s computer is represented by the expression 0.08 (55h) + 55h, where h represents the number of hours it takes to fix Azar’s computer.
What percentage sales tax is Azar being charged? Explain your answer using 1-2 sentences
What part of the expression represents the dollar amount of sales tax Azar must pay?
Answer:
these are 5 points look clearly.XD
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Given,
The total cost after sales tax to fix Azar’s computer is represented by the expression:
- 0.08 (55h) + 55h
where h represents the number of hours it takes to fix Azar’s computer.
We need to find out what percentage of sales tax is Azar being charged.
and what part of the expression represents the dollar amount of sales tax Azar must pay.
What represents sales taxes?It is mostly represented by a percentage.
We have,
100% = 100/100 = 1
50% = 50/100 = 1/2 = 0.5
25% = 25/100 = 1/4 = 0.25
20% = 20/100 = 1/5 = 0.2
We have,
- 0.08 (55h) + 55h
The sales tax is also charged according to the number of hours so,
In the expression 0.08 can be written as a percentage.
0.08 = 8 /100 = 8%
The percentage sales tax is 8%.
Now,
0.08 55(h) means the sales tax Azar must pay.
For 1 hour,
0.08 x 55 = 4.4 is the sales tax.
For 2 hours,
0.08 x (55x2) = 0.08 x 110 = 8.8.
And so on,
So,
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Thus,
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Step-by-step explanation: The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
