The answer is B
2x+5y=3(1) times it by 1
-x+3y=-7(2) times it by 2
____________________
2x+5y=3
-2x+6y=-14
__________
11y=-11
Y=-1
Now we have to found x..... you have to plug in -1 in 2x+5y=3...
2x+5(-1)=3
2x-5=3
2x=3+5
2x=8
X=8/2
X=4
There are your 2 solutions... hope you understand
1. At the very top is 2 pairs of equal adjacent sides. In top left corner
I hope I helped somewhat!!
Answer:
Step-by-step explanation:
Use this to remember the trigonometry ratios:
SOH-CAH-TOA
Because:
Sine=Opposite/Hypotenuse → SOH
Cosine=Adjacent/Hypotenuse → CAH
Tangent=Opposite/Adjacent → TOA
Use the inverse of the tangent ratio since you need to find the angle measure.

I can't see any slick, easy way to tell without finding
the intercepts, so here goes:
The y-intercept is the value of H(n) when 'n' is zero.
H(0) = -13(0) - 421
= - 421 .
The n-intercept is the value of 'n' when H(n) is zero.
0 = -13n - 421
Add 13n to each side: 13n = - 421
Divide each side by 13 : n = - 421/13 = - 32.4...
Connor should set up the viewing window so that 'n' displays
at least down to - 33 , and H(n) displays at least down to - 421 .
Answer: y =
Step-by-step explanation:
We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.
We could find the points (0,-3) and another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.
(0,-3)
(3,-2)
y -3 - (-2) = -1
x 0 - 3 = -3
-1/-3 = 1/3
so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3
so the equation will be y = 1/3x - 3
