The table and the graph below each show a different relationship between the same two variables, x and y: How much more would the value of y be on the graph than its value in the table when x = 12? (1 point) a 20 b 30 c 60 d 70
Answer:
c. 60
Step-by-step explanation:
in the table :
x = 12 , y = 12×25=300
on the graph :
x= 12 , y = 12×30=360
so, the difference is 360-300 = 60
In table
Rate of change
(125-100)/(5-4)25Whne x=12
y=12(25)=300In graph
Rate of change
(120-60)/230When x=12
y=12(30)=360
Difference
360-300=60What are the answers to these

In a study to determine frequency and
dependency of cell-phone usage relative to
students in Grade 11 and Grade 12, there
were 285 students
chosen at random, and
the following results were recorded. What is the probability that a student who does not have a cell phone is from grade 11?
Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:
p = 18/30 = 0.6.
0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

Answer:
x = 1°
Step-by-step explanation:
Bisection means splitting the angle in to 2
So that means 4x-1 = 2x+1
4x-1 = 2x +1
4x = 2x + 2
2x = 2
x = 1°

In the diagram, a∥b and b∥c. Find the values of x. PLEASEEE HELP
The order of the answers doesn't matter.
================================================
Explanation:
a || b means the two lines a and b are parallel
If a || b and b || c, then a || c by the transitive property. Think of it like chaining pieces together.
Since a || c, this means the alternate exterior angles |5x+15| and 100 are congruent, or the same measure.
Solve for x
|5x+15| = 100
5x+15 = 100 or 5x+15 = -100
5x = 100-15 or 5x = -100-15
5x = 85 or 5x = -115
x = 85/5 or x = -115/5
x = 17 or x = -23
The value of x is 17.
What is alternate exterior angle?When a transversal intersects two or more lines, alternate exterior angles are produced. These angles are created on the various transversal sides' outer edges.
Any two parallel lines that cross a transversal produce a few pairs of angles with the transversal. In the area inside the parallel lines, interior angles are generated, whilst alternative external angles are created in the area outside the parallel lines.
Given:
<1 = 5x + 15
<2 = 100
Using alternate exterior angle
5x + 15 = 100
5x = 100- 15
5x = 85
x= 85/5
x= 17
Hence, the value of x is 17.

Step-by-step explanation:
what is the slope of the equation -5x + 8y = 30?
Answer:
The slope is 5/8
Step-by-step explanation:
-5x+8y = 30
Add 5x to each side
8y = 5x+30
Divide by 8
8y/8 = 5/8x+30/8
y = 5/8x + 15/4
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is 5/8
Answer: 5/8
Step-by-step explanation:
You would first need to put the equation into standard form. so you add 5x on both sides
Then you divide 8 on both sides
that would give you y=5/8x+3.75
The slope is 5/8

Suppose a cookie company has found that the number of cookies it sells is inversely proportional to the price of each cookie. If it sells 50 cookies per day when the price of each cookie is $4, how many cookies would it sell per day if the price of each cookie were $2?
Answer:
Step-by-step explanation:
The inverse proportional formula is
[tex]y=\frac{k}{x}[/tex] where y is the number of cookies sold, and x is the price per cookie. If we fill in the info given, we can find what it is we are being asked.
When x = 4 (the price of each cookie is $4), 50 cookies are sold (y = 50). Filling in to solve for k:
[tex]50=\frac{k}{4}[/tex] so
k = 200. Using that value of k along with a price of 2 (x = 2), we can find the number of cookies sold, y.
[tex]y=\frac{200}{2}[/tex] so
y = 100 cookies sold when the price is $2 per cookie.

What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
From the given information we have a reference angle of 52° opposite to it is the height(h) of the pole and a shadow which is the adjacent side is 18 feet.
We know, tan = opposite/adjacent.
Therefore, tan52° = h.18.

What expression is equivalent to 3-(-2+5)
Answer:
Ok ok, I see. So the answer is -9.
Step-by-step explanation:
We know the expresion is:
-3(-2+5)
We need to distrubute the -3 to what is in the parthese.
When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:
-3*-2=6
and:
-3*5=-15
Which we can rewrite as:
(6-15)
Subtract 15 from 6 and you get -9:
6-15=-9

Mary Beth bought 45 oz of flour for her bakery. She used 17.3 oz to make a loaf of bread, and 0.83 oz for each muffin. How many muffins did Mary Beth make if she had 18.57 oz of flour left over?
Answer:
11
Step-by-step explanation:
this equation can be derived from the question
45 oz - 17.3 oz - 0.83x oz = 18.57 oz
where x = number of muffins made
combine like terms
45 oz - 17.3 oz - 18.57 oz = 0.83x
9.13 = 0.83x
x = 9.13 / 0.83
x = 11
