if you knew that f(-4)=8, then what (x,y) coordinate point must lie on the graph of y=f(x?)
Answer:
(-4,8)
Step-by-step explanation:
so f(-4)=8 this is easy
the -4 is the x
beause f(x)=y
so the 8 is the y
when y is f(-4)=8 then the cordinate points are (-4,8)

Calculate the rate of change for the following data:
x y
-1 5
2 -4
7 -19
10 -28
A. 6
B. -9
C. -3
D. 4
Given:
The table of values.
To find:
The rate of change.
Solution:
From the given table it is clear that the rate of change is constant and function passes through two points (-1,5) and (2,-4). So, the rate of change is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-4-5}{2-(-1)}[/tex]
[tex]m=\dfrac{-9}{2+1}[/tex]
[tex]m=\dfrac{-9}{3}[/tex]
[tex]m=-3[/tex]
So, the rate of change is -3.
Therefore, the correct option is C.

For a crafts fair, Charlie made 25 necklaces with 96 beads in each necklace. Shaniqua made 28 necklaces with 84 beads in each necklace. Who used more beads? _____________________ How many more beads? ____________________
Answer:
A. Charlie
B. Charlie used 48 more beads than Shaniqua
Step-by-step explanation:
Charlie:
25 necklaces with 96 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 96 × 25
= 2,400 beads
Shaniqua:
28 necklaces with 84 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 84 × 28
= 2,352 beads
A. Charlie used more beads
B. 2,400 beads - 2,352 beads= 48 beads
Charlie used 48 more beads than
Shaniqua

Find x, y
Answer:
x=1.25, y=1.75
Step-by-step explanation:
The two triangles formed (one triangle with side lengths of 5, 7, 8 and another with sides 5+x, 10, and 7+y) are similar, because they share the same angle measures.
Now, 2 sides given that we can compare ratios with are the side with length 8, and the side with length 10. 10/8= 1.25, which is the ratio of the sides on these 2 triangles.
Now we want to find what the side '5+x' is equal to. To do that we can use our ratio, and multiply 5 by 1.25 to find '5+x'. This is 6.25. To find x, all we need to do is subtract 5 from 6.25, which is 1.25.
Let's find y now. Do the same thing that we did with the side '5+x'; find what '7+y' is by multiplying 7 by 1.25, which is 8.75. 8.75-7= 1.75.
Hope this helps! :)
Find the missing side in the right triangle, Round to the nearest tenth,

Hello!
[tex]\large\boxed{c = 12.65}[/tex]
Use the Pythagorean Theorem to solve for the hypotenuse:
a² + b² = c²
Plug in the given values:
12² + 4² = c²
144 + 16 = c²
160 = c²
Take the square root of both sides:
c = √160
c ≈ 12.65.
Answer:
12.6
Step-by-step explanation:
12 square plus 4 square then the root of that equals 12.6

What is the answer to this question
Answer:
a. 80g fish
b. 200g butter
Step-by-step explanation:
a. you have to divide it by 3 because 2 is 1/3 of 6 so 240/3 = 80g of fish.
b. multiply by 2.5 because 15 is 2.5 times 6 so 80*2.5=200g of butter.
Answer:
a) 80g of fish
b)200g of butter
Step-by-step explanation:
a) 240/6=40g per people
40*2=80
b)80/6=13 1/3g per people
13 1/3*15=200

Find the greatest common factor of 28 and 63
Answer:
The Greatest Common Factor (GCF) for 28 and 63, notation CGF(28,63), is 7.
Step-by-step explanation:
The factors of 28 are 1,2,4,7,14,28;
The factors of 63 are 1,3,7,9,21,63.
So, as we can see, the Greatest Common Factor or Divisor is 7, because it is the greatest number that divides evenly into all of them.

The access code to a houses security system consists of 6 digits. How many different codes are available if each digit can be repeated? Please show work.
Answer:
1,000,000
Step-by-step explanation: Since there are 10 possible digits, we know that there is a 1/10 chance for any possible digit in any slot. So, since there are 6 slots we can do 1/10^6, or 1 in 1 million.
So, 720 ways are available if each digit can be repeated

Is this relation a function? Explain how you know.
Answer:
The relation is a linear function with the equation: y = -6/5x + 3/5
Step-by-step explanation:
Question 5)
The given graph is a straight line.
We know that the graph of a linear function is a straight line that can be written in the form
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
The slope of the line can be determined by taking two points
(3, -3)
(-2, 3)
Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(3,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:3\right)[/tex]
[tex]m=\frac{3-\left(-3\right)}{-2-3}[/tex]
[tex]m=-\frac{6}{5}[/tex]
From the graph, the y-intercept can be obtained by setting x=0 and check the corresponding y-value of y.
or substituting m = -6/5 and (3, -3) in the slope-intercept form to determine y-intercept 'b'.
[tex]y = mx+b[/tex]
[tex]-3\:=-\frac{6}{5}\left(3\right)\:+\:b[/tex]
[tex]-\frac{18}{5}+b=-3[/tex]
[tex]b=\frac{3}{5}[/tex]
now substituting m = -6/5 and b = 3/5 in the slope-intercept form to determine the equation of the linear function
y=mx+b
y = -6/5x + 3/5
Therefore, the relation is a linear function with the equation: y = -6/5x + 3/5

2x^3y + 18xy - 10x^2y - 90y part b: rewrite the expression completely factored.
Answer:
Part A: Factor out the GCF. In this case, the GCF is 2y. So it looks like
2 x^3 * y+18xy-10 x^2 * y-90y=2y (x^3 - 5 x^2 + 9x-45)
Part B: The result from above will need to be factored by grouping.
Part C: If you switch the terms, the factoring will work out differently, but at the end, the factorization will be the same.
