Answer:
we can determine whether a function is linear or nonlinear simply by looking at its graph! Because the rate at which y is changing with respect to x is constant in a linear function, the graph of a linear function is a line, as the name implies.
Step-by-step explanation:
Answer:
Basically a Linear function is a function that has at least both of these:
Step-by-step explanation:
1. A slope, Requirement: rate of change stays constant)
2. One input goes to goes to only one output(however a output can have two different inputs but they must only go to that one output).
example:
x | y
________
0 | 25
2 | 85
4 | 145
6 | 205
The slope for that example was 60.
you can use slope intercept form to find your answer equation being:
Y = mx + b
y = total
m = slope
x = domain
b = y- intercept

x-y=3. 2x-3y=4
Answer:
x - y = 3
2x - 3y = 4
Igualación
Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)
3y + 4
x = y + 3 x = ---------------
2
3y + 4
y + 3 = ---------------
2
2 (y + 3 ) = 3y + 4
2y + 6 = 3y + 4
se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo
3y - 2y = 6 - 4 ⇒ y = 2
sustituimos el valor de y en cualquiera de las dos para obtener el valor de x
x - 2 = 3 ⇒ x = 5
Solución
x = 5
y =2
Find (9.3 × 106) + (1.8 × 104). Express your answer in scientific notation.
Answer:
(9.3 × 106) + (1.8 × 104) =
985.8 + 187.2 =
1173
Step-by-step explanation:
The required scientific notation of (9.3 × 10^6) + (1.8 × 10^4) is 93.18E+5.
To find (9.3 × 106) + (1.8 × 104) and express the answer in scientific notation.
An expression in the form of abE+5 is scientific notation.
To Write the expression in the scientific notation, for example, 12.34 * 10^6
First, put the non-zero digit with desired decimal points in order to show a more simple value, and Put E after the digit and add + and - sign after it which shows the 10 exponents of the digit positive or negative. Then put the value of the exponent. eg 12.34E+6.
⇒(9.3 × 106) + (1.8 × 10^4)
⇒ (9.3 × 106) + (0.018 × 10^6)
⇒ (9.3 + 0.018)× 10^6
⇒ (9.318)× 10^6
For scientific notation
=93.18E+5
Thus, the required scientific notation of (9.3 × 10^6) + (1.8 × 10^4) is 93.18E+5.

Ann will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $43.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $57.98 and costs an additional $0.12 per mile driven. How many miles would Ann need to drive for the two plans to cost the same?
Answer:
700 miles
Step-by-step explanation:
Let's write the expressions for each plan.
Plan 1 has an initial fee of $43.98 and an additional $0.14 per mile m.
So, we can write the following expression:
[tex]43.98+0.14m[/tex]
Plan 2 has an initial fee of $57.98 and an additional cost of $0.12 per mile.
So, we can write the following expression:
[tex]57.98+0.12m[/tex]
We want to find after how many miles Ann needs to drive for the two plans to cost the same. So, let's set the two expressions equal to each other and solve for m:
[tex]43.98+0.14m=57.98+0.12m[/tex]
Subtract 43.98 from both sides:
[tex]0.14m=14+0.12m[/tex]
Subtract 0.12m from both sides:
[tex]0.02m=14[/tex]
Divide both sides by 0.02:
[tex]m=700[/tex]
So, after 700 miles, the price of the two plans will cost the same.
Further notes:
This means that if Ann is driving for less than 700 miles, Plan 1 is the cheaper choice since it costs the least to begin with.
However, if Ann is going to drive for more than 700 miles, Plan 2 is the cheaper choice since it has a lower cost per mile additional cost.
28. Kay is saving $200 a month into an account earning 5% interest. How long will it
take her to save $20,000?
Step-by-step explanation:
Accumulated value = $20,000.
A = P + I, P = principal, I = Interest.
I = 200*5*t/100
I = 1000t/100 = 10t
2000 = P + I = 200 + 10t
2000 - 200 = 10t
1800 = 10t, t = 180.
Therefore, it would take her 180 years to save $20,000.

The temperature unit of Kelvin is used to determine the absolute temperature scale. such as “absolute zero" or “infinite cold." The formula to convert Fahrenheit to Kelvin can be expressed as K = 5/9(F - 32) + 273. where K is the degrees in Kelvin and F is the temperature in Fahrenheit.
Rearrange the formula to find the temperature of Fahrenheit in terms of Kelvin.
Solve for F, keeping the answer in fraction form
Answer:
[tex]F = 32 + \frac{9}{5}(K - 273)[/tex]
Step-by-step explanation:
Given
[tex]K = \frac{5}{9}(F - 32) + 273[/tex]
Required
Solve for F
[tex]K = \frac{5}{9}(F - 32) + 273[/tex]
Subtract 273 from both sides
[tex]K - 273= \frac{5}{9}(F - 32) + 273 - 273[/tex]
[tex]K - 273= \frac{5}{9}(F - 32)[/tex]
Multiply through by [tex]\frac{9}{5}[/tex]
[tex]\frac{9}{5} *(K - 273)= \frac{9}{5} * \frac{5}{9}(F - 32)[/tex]
[tex]\frac{9}{5}(K - 273)= F - 32[/tex]
Add 32 to both sides
[tex]32 + \frac{9}{5}(K - 273)= F - 32 + 32[/tex]
[tex]32 + \frac{9}{5}(K - 273)= F[/tex]
[tex]F = 32 + \frac{9}{5}(K - 273)[/tex]

A. Vertical compress by a factor of 5
B. Vertical shift up 5 units
C. Reflect over x-axis
D. Vertical stretch by a factor of 5
Answer:
The correct answer is A. Vertical compress by a factor of 5
Step-by-step explanation:
When graphed without the 5, the curve is very wide, but when the 5 is added, the curve compresses and narrows itself, therefore a vertical compress occurs by the factor of 5.

If Jay runs for 20 minutes and burns 112 calories. How many calories will he burn if he ran for 45 minutes? Pls help me Imao im dying inside ;_;
Jay burns 252 calories in 45 minutes
Step-by-step explanation:
This is proportions so put 20/45 represents minutes and 112/x represents calories. Jay runs 20 minutes and burns 112 calories. so if Jay runs for 45 minutes so he burns 252. so x=252
20/45 112/x multiply 45 and 112 and then divide 20 and you get an answer of 252. To double check if you got the right answer you multiply 20 and 252 and you get the same answer as 45 x 112
I know this because I am learning about proportions so it is simple to me to answer.
The cost of printing T-shirts is defined by the equation C = 250+5.5n, where C represents the total
cost and I represents the number of T-shirts. If the school paid $965.00, how many T-shirts were
printed?
Answer:
The school paid for printing 130 T-shirts
Step-by-step explanation:
Function Models
We are given the cost of printing n T-shirts as the equation:
[tex]C=250+5.5n[/tex]
For example, if 10 T-shirts were printed, the school would pay:
[tex]C=250+5.5(10)=250+55=\$305[/tex]
We know the school paid $965 and are required to find the number of T-shirts that were printed. If we use the equation with C=965, we can solve it for n:
[tex]965=250+5.5n[/tex]
[tex]965-250=5.5n \Rightarrow 5.5n=715[/tex]
Solving:
[tex]n=715/5.5=130[/tex]
The school paid for printing 130 T-shirts

A goodness of fit test will be conducted for the following hypotheses. This type of test is always an upper tail test. The p-value approach will be used, meaning that the given level of significance, α = 0.01, will be compared to the area under the curve to the right of the calculated test statistic.
H0 : pA = 0.40, pB = 0.40, and pC = 0.20
Ha : The population proportions are not pA = 0.40, pB = 0.40, and pC = 0.20.
The goal of the hypothesis test is to determine if the observed proportions are significantly different from the given proportions. A sample size of 200 yielded 20 in category A, 100 in category B, and 80 in category C. Assuming the hypothesized proportions are true, then the expected frequencies in each category will be the product of the hypothesized proportions and the sample size.
expected frequency = category proportion(sample size)
The proportion for category A is assumed to be 0.40. Use the sample size of 200 to find the expected frequency for this category, eA.
expected frequency = category proportion(sample size)
eA = ( _____ ) (200)
The proportion for category B is assumed to be 0.40. Use the sample size of 200 to find the expected frequency for this category, eB
expected frequency = category proportion(sample size)
eB = ( ______ ) (200)
The proportion for category C is assumed to be 0.20. Use the sample size of 200 to find the expected frequency for this category, ec expected frequency = category proportion(sample size)
eC = ( ______ )(200)
Answer:
1. 80
2. 80
3. 40
Step-by-step explanation:
The question requires us to Use the sample size of 200 to find the expected frequency for categories A, B and C
1. (Category proportion)(sample size)
eA = 0.40x200
= 80
2. (Category proportion)(sample size)
eB = 0.40x200
= 80
3. (Category proportion)(sample size)
eC = 0.20 x 200
= 40
The answers are 80, 80 and 40 respectively.
