x-5=-y
3x-10=2y
Answers
Answer:
(4,1)
Step-by-step explanation:
Multiply the first equation by -3
(x-5=-y)*-3 = -3x+15=3y
Then combine like terms with the new equation and the second equation
(-3x+15=3y) + (3x-10=2y) = 5=5y
Divide 5 by both sides
1=y
Plug in 1 for y in an equation. Doesn’t matter which one and solve
x-5=-(1)
Distribute the negative sign to the 1
x-5=-1
Add 5 to both sides
x=4
X-5= -y
-X+5=y
-4+5=y
1=y
3X-10=2(-2+5)
3X-10= -2X+10

Answers
Answer:
hope this helps!!...the last one is the last box that's at the top
Step-by-step explanation:
The slope of a graph is the rate of change of the graph
Graphs 3 has a slope greater than 1Graph 2 has a slope less than 0Graph 4 has a slope equal to 0When the y values of a graph with the x values, the graph will have a positive slope.
From the figures, graph 3 follows the above highlight.
Hence, graph 3 has a slope that is greater than 1
When the y values of a graph decreases, as the x values increases, the graph will have a negative slope.
From the figures, graph 2 follow the above highlight.
Hence, graph 2 has a slope that is less than 0
A graph with a horizontal line will have its slope to be 0.
Hence, graph 4 has a slope equal to 0

In ΔFGH, h = 9.6 inches, f = 2.5 inches and ∠G=78°. Find the length of g, to the nearest 10th of an inch.
Answers
Answer:9.4
Step-by-step explanation:
Answer: 9.4
Step-by-step explanation:
S.A.S.→Law of Cosines
a^2=b^2+c^2-2bc\cos A
g^2 = 9.6^2+2.5^2-2(9.6)(2.5)\cos 78
g^2 = 92.16+6.25-2(9.6)(2.5)(0.207912)
g^2 = 92.16+6.25-9.97976
g^2 = 88.43024
g=√88.43024 ≈9.404≈9.4
