How can you tell if a graph is linear or non-linear?
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
Solve the equation for x
wx = y
Answer:
x = y/w
Step-by-step explanation:
wx = y
Divide each side by w
wx/w = y/w
x = y/w
Find the range of the relation {(–2, 3), (–1, 3), (–1, 5)}. Then determine whether the relation is a function.
Answer:
Range{ 3,5}
This is not a function
Step-by-step explanation:
The range is the output values
Range{ 3,5}
This is not a function since x = -1 goes to two different output values of 3,5

Tim completely covered a square table using 75.3 in^2 of table cloth without any overlap. Which measurement is closest to the side length of the table?
Answer:
[tex]Length = 8.7\ in[/tex]
Step-by-step explanation:
Given
Shape: Square
[tex]Area = 75.3in^2[/tex]
Required
Determine the Length of the table
This is calculated using:
[tex]Area = Length^2[/tex]
Substitute 75.3 for Area
[tex]75.3 = Length^2[/tex]
Take square roots of both sides
[tex]\sqrt{75.3} = Length[/tex]
[tex]Length = \sqrt{75.3}[/tex]
[tex]Length = 8.67755725997[/tex]

The required decimal form of two hundred five thousandths is 0.205.
Given that,
To determine the Two hundred five thousandths in decimal form,
Decimal value is defined as showing the place value of the digits in a decimal number. If any proportion of the digit is lower than 1 it would be represented after the dot right to the absolute value,
For example= 0.25 where the absolute value is zero and 25 is the proportion less than 1.
Here,
Two hundred five thousandths imply,
Dividing the number 205 by 1000
= 205 / 1000
= 0.205
Thus, the required decimal form of two hundred five thousandths is 0.205.

Answer:
51°
Step-by-step explanation:
Remember, all 3 angles must add up to 180°
We can tell that this triangle is a right triangle, or a triangle that has a 90° angle. We also have another angle given, which is 39°. Currently we have two angles given.
Since all 3 angles have to add up to 180°,
90 + 39 + x = 180°
129 + x = 180°
180 - 129 = x
x = 51°
The missing angle is 51°
To see if your calculation is correct, you could add all 3 angles, and it should give you 180 as a sum.
90 + 39 + 51 = 180
Correct!

The solution of the given equation 4x² - 100 = 0 will be x = 5.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
4x² - 100 = 0
4x² = 100
Taking square root on both sides;
4x² = 100
√4x² = √100
2x = 10
So,
x = 5

Answer:

I hope this helps!
The equivalent expression is 6.
Option B is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex]216^{1/3}[/tex]
6 x 6 x 6 = 216
This can be written as,
6³ = 216
Now,
[tex](6^3)^{1/3}[/tex]
= [tex]6^{3\times1/3}[/tex]

a) Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? Show your work.
b) If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price.
c) The shoe store clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon?
Answer:
A) 37+42=79(1.07)=84.53
B) you would take off the discount and that equals 59.25 then you would apply taxes 63.40
C)9.48 and 7.11
Step-by-step explanation:
Answer:
a) $84.53
37+42=79
79(0.07)=5.53
79+5.53=84.53
b) $56.50
You have to multiply the cost of both shoes by 0.25 to get the amount of money that Isaac gets discounted. Then you subtract that amount from the cost of the shoes to get the new price. Then you multiply the new price by 0.07 to get how much he will be taxed. Finally, you add the tax to the total.
c) Before the coupon is applied: $10.08
After the coupon is applied: $9.48
84(0.12)=10.08
79(0.12)=9.48
