HELP PLEASE WITH MATH

kifflom [539]

14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10

Could someone help i’ll mark brainliest! please explain too

Answer:

C. 8

Step-by-step explanation:

I almost thought this was going to be Pythagorean Theorem, but no.

Use Cosine Law:

cos θ = $\frac{10^2 + 21^2 - 17^2}{2(10)(21)}$

θ = cos−1(0.6)

θ = 53.130...

Now use the SOHCAHTOA ratio for sine ( $\frac{opposite}{hypotenuse}$ ) to find x now that you have one angle:

sin θ = $\frac{x}{10}$

x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)

x = 8

Write the equation of the line that passes through the points (-2,9) and (2,6). Put your answer in fully simplified point-slope

maw [93]

Answer:

4y = -3x +30

Firstly you have to look for the gradient or slope using the points given in the question.

Then substitute the gradient (m) into y= mx+ c
