Answer:
The equation of the line is ![y=x+13](https://tex.z-dn.net/?f=y%3Dx%2B13)
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we have
(-2,11) and (9,22)
substitute
step 2
Find the equation in slope intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
b is the y-intercept
we have
![point\ (-2,11)](https://tex.z-dn.net/?f=point%5C%20%28-2%2C11%29)
substitute in the equation and solve for b
![11=(1)(-2)+b](https://tex.z-dn.net/?f=11%3D%281%29%28-2%29%2Bb)
![11=-2+b](https://tex.z-dn.net/?f=11%3D-2%2Bb)
Adds 2 both sides
![b=11+2\\b=13](https://tex.z-dn.net/?f=b%3D11%2B2%5C%5Cb%3D13)
The equation of the line is
![y=x+13](https://tex.z-dn.net/?f=y%3Dx%2B13)
To do these problems, you need to multiply your (x - 3) by something to make it the same as the first number under your radical sign. For example, for the first step, I multiplied (x - 3) by -2x^2 to get (-2x^3 +6x^2). When you subtract it from the number under your radical like you would in regular long division, you can change its signs to cancel out the first number under the radical. The blocky-looking subtraction signs are ones I changed. Your final answer is (-2x^2-10x-27) with a remainder of -79.
Answer:
I can answer if u post a pic or at least a link
Step-by-step explanation:
<span><span>27≤7x+6</span> </span>
to solve for x you'll have to subtract 6 from both sides then divide both sides by 7
<span><span>21≤7x</span></span>
<span><span /></span>
<span><span><span>3≤x</span> </span></span>
40-20 = 20 meaning your answer is The Temperature Changed 20° That Day.
