Answer:
A function is a relation that is either
one-to-one, meaning each output only has one inputmany-to-one meaning some outputs can have more that one input, but all inputs only have one outputSo, That pic is cramped, don't even know what functions are being referenced but
from the a, b, c, d relation
It is not a function because some inputs have more that one output, which fails our man-to-one ruleFrom the equations
-3x = 15 is not a function, because it only has one input but more than one output breaking rule 12y=10 is a function because every input x has only one output y, it is many-to-one3x-0.25y=3 is a function, it is one to oneFrom the graph
the line is a function, since it is many-to-oneFrom the points
the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a functionRelated Questions
The school store earned $625.32 one week, and then $98.36, $145.98, and $304.09 during the next three weeks. How much did the school store earn in the four weeks?
Answers
Answer:
The store earned $1173.75 in the 4 weeks
Step-by-step explanation:
To calculate the amount earned by the school in the 4 weeks, we are going to add all what had been earned in the previous weeks;
Mathematically that would be;
$625.32 + $98.36 + $145.98 + $304.09 = $1,173.75

In the rhombus, the measure of angle 1 = 18x, the measure of angle 2 = x + y, and the measure of angle 3 = 30z. Find the value of x + y + z. The diagram is not drawn to scale.
Answers
Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93

Answer:
The required equation of the line is:
[tex]y=\frac{1}{4}x-1[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-4x+3[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1=\frac{1}{4}\left(x-8\right)[/tex]
add 1 to both sides
[tex]y-1+1=\frac{1}{4}\left(x-8\right)+1[/tex]
[tex]y=\frac{1}{4}x-1[/tex]

Answer:
∠KNC = 99°
Step-by-step explanation:
∠JNM + ∠KNC = 180 (it is a straight line)
∠KNC = 180 - ∠JNM
∠KNC = 180 - 81
∠KNC = 99°
Answer: 99°
Step-by-step explanation: They are supplementary so 180 - 81 = 99

there is a certain number. If you add 30 7 to it, then subtract 22 7 from the previous result, and then subtract that difference from 59/7, after that you will get 19 7. What is a certain number?
Answers
Step-by-step explanation:
59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7
59 / 7 - ( x + 8 / 7 ) = 19 / 7
59 / 7 - x - 8 / 7 = 19 / 7
- x = 19 / 7 - 59 / 7 + 8 / 7
- x = - 32 / 7
x = 32 / 7

Since I don't have the numbers to plot, I'll tell you where to begin
Step-by-step explanation:
When plotting temperatures, it's important to remember positives and negatives
It's always a good idea to start by marking the halfway point as zero
Then, if the numbers are in the tens, make each increment an increasing value of ten/-ten in each direction.
If they're low, (in the ones digits) then just mark the numbers on the increments in the positive/negative directions

Mason says you can find an equivalent ratio by adding the same number to both
quantities in a ratio. For example, 2:3 is equivalent to 3:4 because 2 + 1 = 3 and
3+1 = 4. Is Mason correct? Explain your thinking.
Answers
Answer:
No Mason is not correct you would use fractions and find a common denominator such as 12 and 2/3 would be 8/12 and 3/4 would be 9/12 therefore the two ratios are not equivelent
No, the statement is not correct.
What is ratio?Ratio is the comparison of two quantities which is obtained by dividing the first quantity by the other. If a and b are two quantities of the same kind and with the same units, such that b is not equal to 0, then the quotient a/b is called the ratio between a and b. Ratios are expressed using the symbol of the colon (:). This means that ratio a/b has no unit and it can be written as a : b
The example given here is not relevant.
This is because if 2:3 is added by 1/1
gives 3/4 or 3:4
but 3:4 cannot be more simplified.
So, let us make the equivalent denominator for both
2/3*4*4= 8/12
3/4*3/3=9/12
So, 2:3 ≠3:4

Answer:
A, B, C, D, F . . . as written
Step-by-step explanation:
Any mixed number, fraction, or finite or repeating decimal is rational. The only one in your list that is irrational is E, which appears to be a non-repeating, non-terminating decimal.
__
Your B selection appears to be 11² = 121, an integer and a rational number.
If your B selection is supposed to be √11, then that number is irrational, as it is not the root of a perfect square.
E is irrational; B is rational as written, but irrational if it should be √11. All the others are rational.
