If f(x) = 3x^2 – 2 and g(x) = 2x + 4, find (f- g)(x).

Answer: There are 11 dimes and 17 nickels.

Step-by-step explanation:

Answer:

c(n) = 4n +20

let m = c(n)

m= 4n +20

make n the subject

m -20 =n

4.

inverse function of c(n)= n-20

4

It is a must that one replaces the m with the n in order to get the final answer

Answer:

(-3,4)

Step-by-step explanation:

x + 2y = 5

-3 + (2*4) = 5

-3 + 8 = 5

5 = 5

2x + 3y = 6

(2*-3) + (3*4)=6

-6 + 12 = 6

6 = 6

Answer:

(-3,4)......... multiply the first equation by the coefficient of y i.e 3 (of 2nd equation)...

again multipy the 2nd eq by the coefficient of y i.e 2 (of 1st eq)

and finally solve the eq 3 and 4 ...(solve the both eq formed by multiplying)

Answer:

Sorry man but I can't see the question : (

Step-by-step explanation:

Answer:

the answer is b

Step-by-step explanation:

they should have the same slope so just looking at that you cancel out d. But since it says has a y-intercept of 1 then it would cancel out the other 2. d is perpendicular to it not parallel

Answer:

b. [tex]y=5x+1[/tex]

Step-by-step explanation:

Slope-intercept form:

[tex]y=mx+b[/tex]

When two lines are parallel, their slopes are the same. Note the slope of the given equation:

[tex]y=5x+7\\\\m=5[/tex]

The slope is 5, so the slope for the parallel equation will also be 5:

[tex]y=5x+b[/tex]

Now insert the given y-intercept:

[tex]b=1\\\\y=5x+1[/tex]

Answer: (Decimal: 0.914214) or -1/2 + √2

Step-by-step explanation:

Answer: X = -50

Step-by-step explanation:

1. 1/5x = -10

1/5x = -10

2.Multiply by 1

3.Multiply all terms by the same value to eliminate fraction denominators.

4.Simplfiy

Answer:  y = 1.2x + 1.4

Step-by-step explanation:

1. Write down the coordinates of the first point. Let's assume it is a point with x₁ = -2and y₁ = -1.

2. Write down the coordinates of the second point as well. Let's take a point with x₂ = 3 and y₂ = 5.

3. Use the slope intercept formula to find the slope:

m = (y₂ - y₁)/(x₂ - x₁) = (5-1)/(3-2) = 4/1 = 1.2

4. Calculate the y-intercept. You can also use x₂ and y₂ instead of x₁ and y₁ here.

b = y₁ - m * x₁ = -1 - 1.2*-2 = 1.4

5. Put all these values together to construct the slope intercept form of a linear equation:

y = 1.2x + 1.4

Answer:

Answer:

101.60

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer:

C is the right answer

Step-by-step explanation:

Answer:

slope(m)=change in y/change in x

-7=y-(-2)/x-(-7)

-7=y+2/x+7

-7(x+7)=y+2

-7x-49=y+2

-7x-49-2=y

-7x-51=y (B)

Answer:

AAS since if one of the side has a right angle that is one a straight line, then the other should be a right angle too. Since they also share a side, they must be congruent also, making it AAS.

Step-by-step explanation:

Answer:

The answer is 5/6

Step-by-step explanation:

7/12 + 3/12 = 10/12

10/12 = 5/6 ( divide the numerator and denominator by 2)

Answer:

0

Step-by-step explanation:

The slope of any horizontal line will be zero.

Answer:

slope = m = rise/run = 0/8 = 0

Step-by-step explanation:

Well rise/run is how much it rises over how much it runs.

Note it rises by 0 so 0 on top,

Therefore;

no matter it be 0/1 or 0/1241213261238126836128361  the rise/run also known as slope is always gonna be 0

Reasoning:

0 divided by anything is always 0

Hope this helps

Answer: The answer is B

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

Answer:

b and c

Step-by-step explanation:

Answer:

m = -1

Step-by-step explanation:

3m + 6 = 5m + 8

-3m        -3m

6 = 2m + 8

-8           -8

-2 = 2m

divided by 2

-1 = 1m

m = -1

Answer:

y-intercept:  ( 0 , − 3 )

x-intercept:  ( 3 7 , 0 )

Step-by-step explanation:

Step-by-step explanation:

. We assume, that the number 10 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 10 is 100%, so we can write it down as 10=100%.

4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.

5. Now we have two simple equations:

1) 10=100%

2) x=0.034%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

10/x=100%/0.034%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.034% of 10

10/x=100/0.034

(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x

10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x

10/2941.1764705882=x

0.0034=x

x=0.0034

now we have:

0.034% of 10=0.0034
