Answer:
y = 8/3x - 4
Step-by-step explanation:
Slope-intercept form is represented by [ y = mx + b ] where m = slope and b = y-intercept.
We are given the slope of 8/3 and a y-intercept of -4. So, we can put this information into the formula shown above.
y = 8/3x - 4

The height of a stack of 12 pennies is 18.24 millimeters. What is the thickness of each penny? Please explain how you got your answer :)
9514 1404 393
Answer:
1.52 mm
Step-by-step explanation:
Let p represent the thickness of one penny. Then a stack of 12 pennies will have a thickness of 12p.
12p = 18.24 mm
p = 18.24 mm/12 = 1.52 mm . . . . divide by the coefficient of p
The thickness of each penny is 1.52 mm.

Step-by-step explanation:
You work in a restaurant. Your hourly wage is $5.25. One evening you work from 5:30 to 9:30 and make $34.20 altogether. How much do you make in tips that evening?
Your answer
9514 1404 393
Answer:
$13.20
Step-by-step explanation:
Working h hours and earning t in tips, your earnings (e) are ...
e = 5.25h +t
Solving for t, we get ...
t = e - 5.25h
Filling in the given values, we have ...
t = 34.20 -5.25(4) = 34.20 -21.00 = 13.20
You made $13.20 in tips that evening.
What is the measure of angle D?
A.45
B.122
C.70
D.32
Answer:
D.32
Step-by-step explanation:
14 + 45 = 59
180 - 59 = 121
The oppisite angle in that shape will be equal
so, E= 121
121+27 = 148
180 - 148 = 32
Answer:
D.32
Step-by-step explanation:
14+45=59
180-59=21
the opposite angle in the shape is equal so , E=21
121+27=148
180-148=32
The function shown is reflected across the y-axis to create a new function. Which is true about the domain and range of each function? Both the domain and range change. Both the range and domain stay the same. The domain stays the same, but the range changes. The range stays the same, but the domain changes.
Answer:
its b friends :)
Step-by-step explanation:
If the function shown is reflected across the y-axis create a new function. Both the range and domain stay the same.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that, the function shown is reflected across the y-axis to create a new function. We have to state the domain and range of each function.
The domain and/or range of a function will change when it is transformed. Only the domain will change if the inputs are only transformed. Only the range will change if the transformation only affects the outputs. The domain and range will change if the inputs and outputs are transformed simultaneously.
Thus, if the function shown is reflected across the y-axis creates a new function. Both the range and domain stay the same.

322 rounded to the greatest place value
Answer:
322 rounded to the greatest place value
320After rounding off 322 to the nearest tenths, the resultant number is 320.
What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. Round the number up if 5, 6, 7, 8, or 9 follow the number you are rounding.For instance, 40 when rounded to the nearest ten is 38.
So, 322 rounded to tenth place:
Since in the tenth place, there are 2.Then after rounding off:
322 ⇒ 320Therefore, after rounding off 322 to the nearest tenths, the resultant number is 320.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Arie makes 3 giant sandwiches to share equally with 8 friends. Each friend gets a fraction of a sandwich.
Each friend will get -
{x} = 3/8
{x} = 0.375
So, we can see that -
0 < 0.375 < 1
Therefore, the answer lies between 0 and 1.

Find −1/5+17/10. Write your answer as a mixed number in simplest form.
Answer:
1 1/2
Hope I helped
Answer:
1 1/2
Step-by-step explanation:
To add fractions together you have to have a common denominator. To do this, I multiplied -1/5 by 2 to get -2/10 which has the same denominator (10) as 17/10. now you add the numerator of both fractions. -2+17 equals 15. so your new fraction is 15/10. 15 divided by 10 is 1.5 which you can write as 1 and 1/2.

Step-by-step explanation:
Hope that helps!
An example of two integers that make a zero pair is 6 and -6.
They are additive inverses because they sum up to zero
For two integers to make a zero pair:
They must be equal in magnitudeThey must have opposite signsLet the first number be represented by x
For one to be the additive inverse of the other, the second number must be -x.
x + (-x)
= x - x
= 0
