Answer:

lakes 24

Step-by-step explanation:

Suppose that 24 inches of wire costs 96 cents.
At the same rate, how much (in cents) will 47 inches of wire cost?

Answers

Answer:

Step-by-step explanation:

24inches = 96 cents

To find the cost of 1 inch, divide 96 cents by 24.

1 inch = 96/24 = 4 cents

Then to find the cost of 47 inches, multiply by 4.

47 inches = 47 x 4 = 188 cents.

If f(x) = 3x + 2, then find the value of x such that f(x) = -4.

Answers

Answer:

See Below

Step-by-step explanation:

Solve by substituting

-4 = 3x + 2

-2          -2

-6 = 3x

3x/3 = -6/3

x = -2

Answer:

x = -2

Step-by-step explanation:

So we are given the function f(x) = 3x + 2 and we are asked to find the value of x that makes f(x) = -4. To do this, we can replace f(x) with -4 in the given function and solve for x.

-4 = 3x + 2

Swap sides.

3x + 2 = -4

Subtract 2 from both sides.

3x = -6

Divide both sides by 3.

x = -2

So we have found that x = -2 when f(x) = -4. This means that when x = -2, f(x) = -4.

How are the slope formula and finding slope using "rise over run" related?

Answers

Answer:

they are the same thing

Step-by-step explanation:

Answer:

They are practically the same thing but if you want to get technical then they are related because A slope  a measure of steepness. A line with a large slope, such as 25, is very steep. A  line with a small slope, such as 1 /10 is very flat. So this means it will rise over run if that makes sense.

1. Solve the system of equations by substitution:
y = x - 2
4x – 3y = 11

Answers

Answer:

x = 5

y = 3

Step-by-step explanation:

y = x - 2

4x - 3y = 11

substitute y in the second equation with x - 2

4x - 3(x - 2) = 11

open the parenthesis

4x - 3x + 6 = 11

x + 6 = 11

subtract 6 from both sides of the equation

x + 6 - 6 = 11 - 6

x = 5

now substitute x for 5 in the original equation.

y = x - 2

y = 5 - 2

y = 3

Answers

Answer:

1) 110*,     2) 84*,       3) 80*

Step-by-step explanation:

         These are intersected parallel lines (with only 1 intersecting line), so having missing angles in the questions 1 and 2 opposite from the shown angle is giving the answer away. However, on answer 3, it is on the same side, so for that angle you will need to subtract the angle of the intersecting line by 100* to get 80*. Check by adding the two. 100* + 80* = 180*.

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelogram is dilated with a scale factor of -1/3

Answers

Answer: [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]

Step-by-step explanation:

Transformation rule for dilation:

[tex](x,y)\to(kx,ky)[/tex] , where k = scale factor

Given : Scale factor = [tex]-\dfrac13[/tex]

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)

Vertices after dilation:

[tex](-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)[/tex]

[tex](0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)[/tex]

[tex](6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)[/tex]

[tex](3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)[/tex]

Hence, the coordinates of the image if the parallelogram = [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]
