Answer:

4x-15=y

Step-by-step explanation:

The higher the rise over the run the more steep your slope will be thus 4x is less steep than 8x because it does not rise as much.

The y intercept shifted downward means anything (-10>b) can be plausible for b.

A 100-foot cable is cut into two pieces. The first piece is 18 feet longer than the second. How

Archy [21]

Answer:

first cable- 59ft

second cable-41 ft

Step-by-step explanation:

so you have x+18 which is the first cable and x which is the second cable

x+18+x=100

2x+18=100

2x=82

x=41

plug in x

first cable- 59ft

second cable-41 ft

Please help me with this and dont get any wrong!!!!!

Marianna [84]

1. The answer is A.

Based on the line plot, we can see that Sandy drank 12 juice boxes on October 12th. Each X on the plot represents 2 juice boxes, and there are 6 of them, meaning she drank 12. October 2nd has 1 X, meaning she drank 2 that day.

2. The answer is A.

On a graph, the point (1, 3) would mean that 1 is on the x-axis, and 3 is on the y-axis. Therefore, point B is correct because it is 1 space to the right, and 3 spaces up from the origin.

3. The answer is C.

If the coordinate we're looking for is (4, 0) then on a graph you would move 4 spaces to the right, and 0 spaces up or down. Therefore, point B is the correct choice.

Helpppppp me pleaseeeeeee!!!!!!!!

Answer:

Step-by-step explanation:

think of the flight of a small rocket.. what does it seem like the parabola would look like? down means it looks like a cup or glass , upside down , up mean a cup or glass right side up.

when t = 0 the rocket is at 25, so that's the initial height

it's velocity is initially 200 m/s

put equation from std. form to vertex form

y = a $x^{2}$ + bx +c => y = a(x - h ) ^2 + k

h = -4.9 $t^{2}$ + 200t + 25 =>h = -4.9(t - 20.41)^2 + 2,065.82

(h,k) = (20.41 , 2065.82)

Can you think of any 2x2 matrices d for which cd = dc for all 2x2 matrices c? give 2 different examples of such matricesd.

Ksju [112]

For any arbitrary 2x2 matrices $\mathbf C$ and $\mathbf D$ , only one choice of $\mathbf D$ exists to satisfy $\mathbf{CD}=\mathbf{DC}$ , which is the identity matrix.

There is no other matrix that would work unless we place some more restrictions on $\mathbf C$ . One such restriction would be to ensure that $\mathbf C$ is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking $\mathbf D=\mathbf C^{-1}$ we'd get equality.
