Answer:
y=3.5x
Step-by-step explanation:
Since when x is 0 when y is 0, there is no y-intercept. The ratio with the other values gives the equation y=3.5x, because y is 3.5 times larger than x.

What is the equation of parabola whose vertex is (h, k)?The equation of the parabola whose vertex is (h, k) is
[tex]y = a(x-h)^{2} + k[/tex]
According to the given question.
We have a graph for the function f(x) and g(x).
[tex]f(x) =x^{2}[/tex]..(i)
⇒ the equation of parabola whose vertex is (0, 0)
Since, we know the standard form of the equation of parabola is
[tex]y = a(x-h)^{2} +k[/tex]
Substitute h = 0 and k = 0 in the above equation.
⇒ [tex]y = a(x-0)^{2} +0[/tex]
⇒ [tex]y = ax^{2}[/tex]..(ii) (where, y = f(x))
On comparing the first two equations we get a = 1.
From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).
Therefore, the equation for red graph is given by
[tex]g(x) =a(x-0)^{2} + 2[/tex]
[tex]g(x) = 1x^{2} +2[/tex] (because a = 1)
⇒ [tex]g(x) = x^{2} +2[/tex]
Hence, option c is correct.

Given that slope = -1 and a point (3,-1), write an equation in slope-intercept form of the line?
Answer:
Step-by-step explanation:
point-slope equation of the line: y+1 = -(x-3)
rearrange to solve for y:
y+1 = -x+3
y = -x + 2 slope-intercept form
Answer:
y = -x + 2
Step-by-step explanation:
We are given that a line has a slope of -1 and passes through the point (3, -1)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
As we are already given the slope, we can immediately plug its value into y=mx+b.
Replace m with -1 in y=mx+b.
y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).
Now we need to find b.
As the equation passes through the point (3, -1), we can use it to help solve for b.
Substitute 3 as x and -1 as y.
-1 = -3 + b
Add 3 to both sides
2 = b
Substitute 2 as b in the equation so far.
y = -x + 2

How I got my answer is that you write the numbers and the difference of the each 2 numbers. When you see the pattern is 5, 10, 20, and it might as well be 25 because you are going to start all over with the pattern
Answer:
Cameron will do 79 jumping jacks on Sunday
Step-by-step explanation:
So on Wednesday, he did 4 jumping jacks. On Thursday, he did 5 more jumping jacks than he did on Wednesday (9 total ). On Friday, the difference between Wednesday and Thursday doubled, and it has a difference of 10 new jumping jacks(19 total). On Saturday, the difference between Thursday and Friday doubled from 10 to 20, (39 total). So if the difference keeps up, which it should, The difference between Saturday and Sunday should double from the diffeerence from Friday to Saturday (a difference of 20). So if the difference is doubled, it will be a difference of 40. so 39+40=79.

Which is the correct algebraic expression for "6 less than 3 times a number?
Answer: [tex]\huge\boxed{\ m=7 }[/tex]
Step-by-step explanation: We can break this problem down to understand it. Let the number be m. Three times the number 'm ' is 3.m or 3m. 3 ( m ) - 6 = 15. 3m -6 = 15 add 6 to both sides; 3m -6 + 6 = 15 + 6 3m = 21 dividing both the sides by 3 ,and we get; 3m /3 = 21 / 3 m=7 .

Determine how many cats there will be after 5 years
Answer:
There will be 10 cats in 5 years
Step-by-step explanation:
Since x means the number of years, x = 5
According to PEMDAS, we take care of the exponents first
So the exponent is x, so the exponent is actually 5
So we apply that to 0.28
0.28^5 = 0.002
0.002 x 5719 = 9.84
But... that would be impossible and just plain creepy if there were 9.84 cats lol
So I rounded it to 10 cats
Answer:

Last week, Jack sold x number of hot dogs at the
football game. This week he sold twice as many as
last week, and then he sold 10 more. Write an
expression to show how many hot dogs Jack sold
this week.
Answer:
2x+10
Step-by-step explanation:
Hi there!
To represent last weeks sale, you would have f=x
x= the number of hot dogs he sold last week
Now, to get the expression of this week, you know that he sold TWICE as many as last week, and we know that x represents last week's sale, so you would get 2x.
2 represents twice the sales of the last week, and x represents last week's sales.
But then you also know that he sold 10 more. So he sold twice as many as last week's hot dogs but he also sold 10 more. That's where you get 2x+10
Again, 2x represents twice as many sales this week and the 10 is the 10 more hot dogs he sold.
Really hope this helps!
An expression for hot dogs Jack sold this week is 2x+10.

Write an exponential function in the form y=ab^x that goes through points (0,7) and
(9, 3584).
Answer:y=7(2)^x
Step-by-step explanation:
The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
The general form of exponential function is,
f(x) = abˣ
The function passes through (0,7) and (9, 3584).
Substituting (0, 7),
7 = a b⁰
7 = a (since b⁰ = 1)
So, a = 7
Function is f(x) = 7bˣ
Now Substituting (9, 3584),
3584 = 7 b⁹
b⁹ = 3584 / 7
b⁹ = 512
b⁹ = 2⁹
b = 2
So the function is f(x) = 7(2)ˣ
Hence the function is f(x) = 7(2)ˣ.

When Anthony contracted the flu, he needed tissues and cough drops. Each box of tissues cost $1.69 and each bag of cough drops cost $1.19. By the time he was well again, he had gone through a combined 13 boxes of tissues and bags of cough drops, and he had spent $19.47. How many boxes of tissues did he use? How many bags of cough drops?
Answer:
8 boxes of tissues
5 bags of cough drops
Step-by-step explanation:
You need to write a system of equations.
x = number of tissue boxes
y = number of cough drop bags
x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.
So, your first equation is
x + y = 13
Then, you need to write the second equation.
(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]
That's a lot to read, so here's the equation simplified!
1.69x + 1.19y = 19.47
Now, you have two equations:
x + y = 13
1.69x + 1.19y = 19.47
I would solve with the substitution method.
the first equation can be changed to x = 13 - y by subtracting y from both sides.
Then, your two equations are:
x = 13 - y
1.69x + 1.19y = 19.47
Now, you can plug in that value of x into the second equation!
1.69(13 - y) + 1.19y = 19.47
21.97 - 1.69y + 1.19y = 19.47
subtract 21.97 from both sides
-1.69y + 1.19y = -2.5
Add the y values
-0.5y = -2.5
divide both sides by -0.5
so, y equals 5 bags of cough drops
now that you know what y equals, plug it back into your original equation to find x!
x + y = 13
plug in y
x + 5 = 13
x = 8
so, x = 8 boxes of tissues
Hope this helps! Let me know if you have any questions!

The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month. The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month. Write a system of equations to model th situation. If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month? How many each disc is sold in that month?
Answer:
11 months
788 disc
Step-by-step explanation:
Let
x = number of months
Fry's Electronics;
= 920 - 12x
Blu-ray discs:
= 502 + 26x
Equate both equations
920 - 12x = 502 + 26x
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
number of months = 11
Substitute 11 into any of the equation
Fry's Electronics;
= 920 - 12x
= 920 - 12(11)
= 920 - 132
= 788 disc sold in that months
