B. is the correct answer. If you think about it in slope-intercept form y = mx + b, remember that m is the slope so it would have to be -2. In this case, B is y = -2x + 1 so -2 is the slope :) Hope this helps!
It’s 19. The absolute value of -7 is 7 and the absolute value of 4 is 4. 7 plus 3 times 4 is 19.
5x + 2y = 13
x + 2y = 9
Subtract :- ( note that 2y - 2y = 0):-
4x + 0 = 4
x = 1
From 2nd equation plug in x = 1
1 + 2y = 9
2y = 8
y = 4
Solution to this equation is x=1,y=4
2x + y = 7
5x - y = 14
Adding eliminates the y terms because y + -y = 0 :-
7x + 0 = 21
7x = 21
x = 3
Plug x=3 into second equation:-
5(3) - y = 14
y = 15-14 = 1
solution is x =3, y = 1
Answer: 66.
explanation: Ok so right triangle: 1 right angle or 90° and 2 acute angles (Less than 90°). We know that one of the angles are equal to 24° and the right angle is equal to 90° degrees. Now what? We add those 2 values together. 90 + 24 = 114. In the background, a triangle is equal to 180°. So now that we have our 2 core values together, we subtract. The reason why is because this is a missing value type equation. In these types, (usually indicated by the word find) we can subtract 2 values. Our 2 values is 114 and 180. When we subtract both, we get 66.
The correct answer to your problem is B , D and G
I hope this helps you in your time with me keep up the good work champ!!!:-) ♡
