Answer: x=3.6; y=-2.5
Step-by-step explanation:
To solve this pair of equations, we can use elimination method.
5x+4y=8
10x-4y=46
Add both equations together to cancel out 4y.
15x=54 [divide both sides by 15]
x=3.6
Now that we know x, we can plug it back into any equation to find y.
5(3.6)+4y=8 [multiply]
18+4y=8 [subtract both sides by 18]
4y=-10 [divide both sides by 4]
y=-2.5
Now, we have x=3.6 and y=-2.5.
Answer:
3x=10+13x
We simplify the equation to the form, which is simple to understand
3x=10+13x
We move all terms containing x to the left and all other terms to the right.
+3x-13x=+10
We simplify left and right side of the equation.
-10x=+10
We divide both sides of the equation by -10 to get x.
x=-1
Answer:
Infinite
Step-by-step explanation:
A triangle that has all 60-degree angles is equilateral, which means that all side lengths are the same. However, there are infinite possibilities for the side lengths!
I hope this helped, please give brainliest if this is correct! Thank you!
You need to translate each function statement into a point.
If f(0)=2, then (0,2) has to be on the graph of f. It's not, so that rules out option #1.
Do the same for the other statements to figure out which one correctly identifies a point on each graph.
Answer:
c=1/8
Step-by-step explanation:
2c-1/4=0
2c=1/4
2c/2=1/4/2
c=1/4x1/2
c=1/8
