No he is not correct. For him to be correct the numbers would have to be the same but the negatives and positives would be different.

I don't know if this helps at all, probably not, but I tried. It made sense in my head but it might not make sense to other people. Sorry! Hope this works!

A graph has a constant of proportionality of 7.2. Let y represent minutes and x represent miles.

vodka [1.7K]

Answer:

7.2 minutes per mile

Step-by-step explanation:

If we assume the description means y = 7.2x, the rate 7.2 means each increase in x of 1 mile results in an increase in y of 7.2 minutes. That is the rate is 7.2 minutes per mile.

Which of the following points IS a solution to the system: y > - 3x + 4 / y > 2x / - y < 7 Selected answer is not corre

Lady bird [3.3K]

Answer:

Solution : Third Option

Step-by-step explanation:

The first step here is to make all the signs uniform. As you can see the third inequality has a less than sign, which we can change to a greater than sign by dividing negative one on either side, making the inequality y > - 7.

$\begin{bmatrix}y>-3x+4\\ y>2x\\ y>-7\end{bmatrix}$

Now take a look at the third option. Of course the y - coordinate, 3, is greater than - 7, so it meets the third requirement ( y > - 7 ). At the same time 3 > 1( 2 ) > 2, and hence it meets the second requirement as well. 3 > - 3( 1 ) + 4 > - 3 + 4 > 1, meeting the first requirement.

Therefore, the third option is a solution to the system.

Given: tangent to Circle O.<br><br> If m C = 57°, then m BDR =

Romashka-Z-Leto [24]

∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)

The segments in each figure are tangent to the circle. Find each length.

zubka84 [21]

The tangents are equal length, so
.. 8x = x^2
We presume their length is not zero, so we can divide by x to get
.. 8 = 2x
.. 4 = x

Then the length of each tangent is 8*4 = 32 units.
