Answer:
Look at the explanation.
I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
Answer:
=5/9 or 0.5
Step-by-step explanation:
Answer:
1) x=30 degrees
2)y=20 degrees
1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)
2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20
(I hope this makes sense)
Try this option:
1. according to the condition Kris scored '2x' points, Julio did 'x' points (Kris scored 2 times as many points as Julio).
2. according to the condition Kris'_points+Julio's_points=36_points. It means, that x+2x=36.
3. If to solve this equation (2x+x=36), then Julio scored x=12 points, Kris scored 2x=12*2=24 points.
answer: 12 (Julio); 24 (Kris).
Answer:
A
Step-by-step explanation:
v - 2u
= < - 2, 4 > - 2 < 2.5, - 4 > ← multiply each component by 2
= < - 2, 4 > - < 5, - 8 > ← subtract corresponding components
= < - 2 - 5, 4 + 8 > = < - 7, 12 >
Graph A shows the resulting vector
