Answer:
12
Step-by-step explanation:
Answer:
93
Step-by-step explanation:
if m = 0
11m2 would equal 0
0 - 18m
18m would = 0
so 0 + 93 = 93
Answer:
The lengths that represent the legs of tri ABC are AC and BC
Step-by-step explanation:
AB is the hypotenuse as it is the side opposite to 90°
Answer:
b. 3/1 c. -1/3
Step-by-step explanation:
When a line is parallel to another they don't intersect and instead go in the same direction. Therefore they have the same slope
b. 3/1
When a line is perpendicular it has to be the negative reciprocal. This means that it you have to flip the numbers in the fraction and make it negative (unless it is already negative, then it becomes positive)
c. -1/3
The ordered pair (-1, 6) is the solution to the system of equations.
Step-by-step explanation:
Given equations are;
3x+2y=9 Eqn 1
y=4x+10 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
![3x+2(4x+10)=9\\3x+8x+20=9\\11x=9-20\\11x=-11](https://tex.z-dn.net/?f=3x%2B2%284x%2B10%29%3D9%5C%5C3x%2B8x%2B20%3D9%5C%5C11x%3D9-20%5C%5C11x%3D-11)
Dividing both sides by 11
![\frac{11x}{11}=\frac{-11}{11}\\x=-1](https://tex.z-dn.net/?f=%5Cfrac%7B11x%7D%7B11%7D%3D%5Cfrac%7B-11%7D%7B11%7D%5C%5Cx%3D-1)
Putting x=-1 in Eqn 2
![y=4(-1)+10\\y=-4+10\\y=6](https://tex.z-dn.net/?f=y%3D4%28-1%29%2B10%5C%5Cy%3D-4%2B10%5C%5Cy%3D6)
Solution: (-1, 6)
The ordered pair (-1, 6) is the solution to the system of equations.
