Simple....

you have:

(-15,70) and (5,10)

Using-->>

\frac{  y_{1} -y_{2} }{ x_{1}-  x_{2} }

\frac{70-10}{-15-5} = \frac{60}{-20} = -3

Using y=mx+b...and any of the coordinates....

70= -3(-15)+b

70=45+b

70=45+b
-45  -45

25=b

y=-3x+25

Thus,your answer.

M angle JKL=<br> Help me please! Asap thanks so much :)
Lunna [17]

The measure of the angle <JKL is 56 degrees

<h3>Tangent secant theorem of a circle</h3>

The theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

Given the following parameters

m<IL = 112 degrees

Since the measure of the vertex is half the measure of its intercepted arc, hence;

<JKl = 1/2(m<IL)

Substitute the given parameters into the formula to have;

<JKl = 1/2(112)

<JKL = 56 degrees

Hence the measure of the angle <JKL is 56 degrees

Which of the following is an example of a proper fraction? A. 4 /3 B. 4 /4 C. 3 /4 D. 7 /6
puteri [66]
<span>The proper fraction is c. 3/4. A proper fraction is a fraction that is less than one. A fraction is less than one if its denominator, the number below the line, is larger than its numerator, the number above the line. 4/3 and 7/6 are both greater than one and 4/4 is equal to one, thus none of them are proper fractions.t</span>

Help Please! Thanks so much if u do
Sati [7]

Answer:

$65

Step-by-step explanation:

Let's add up the flat rate and the cost of four tires:

flat rate + 4($122.57/tire) = $555.28

We are to solve for "flat rate."  First, multiply out 4($122.57/tire), obtaining a tire cost of $490.28 total.  Subtracting this tire cost from the $555.28 Janette paid the shop, we get "flat rate" = $555.28 - $490.28, or $65.

Thus, the installation charge ("flat rate") must have been $65.
