Match the graph of:<br><br> please help it’s for a midterm exam

nadezda [96]

Answer:

B

Step-by-step explanation:

Since the inequality sign is greater than or equal to, we need a solid line with the color filled at the top of the graph. This already eliminates answer choice A or D.

Since we know it has to have a solid line, the answer is B.

<h2>For x=2</h2>

$- 10(2) + y = 4$

$- 20 + y = 4$

$y = 24$

<h2>For x=1</h2>

$- 10( 1) + y = 4$

$- 10 + y = 4$

$y = 14$

<h2>For x=0</h2>

$- 10(0) + y = 4$

$0 + y = 4$

$y = 4$

<h2>For x=-1</h2>

$- 10( - 1) + y = 4$

$10 + y = 4$

$y = - 6$

<h2>For x=2</h2>

$- 10( - 2) + y = 4$

$20 + y = 4$

$y = - 16$

An airplane started at point K, travelled 560 miles to point L, adjusted its route and travelled another 575 miles to point M. I

S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

$c^{2} =a^{2} +b^{2} -abcos\beta$

$952^{2} =560^{2} +575^{2} -560*575cos\beta$

$\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2} }{2*560*575} )$

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees

7th grade math help me plzzzz

siniylev [52]

Answer:

17 degrees

Step-by-step explanation:

So to find the answer you need to subtract. If the temp went down 22.1 degrees and it is -5.1 degrees you will subtract 22.1 - 5.1. This equals 17 degrees. You know the answer is correct because you can check your answer by adding: 5.1 + 17 = 22.1. We are disregarding the negative sign.
