Answer:
x=13,y=0
Step-by-step explanation:
We are given a system of equations
For equation 1,square all terms to reduce it
√x²+√y²=169
x+y=13
Make x the subject as required by the question to use substitution method
x=13-y
Plug x=13-y into eqn 2
3(13-y)+2y=39
39-3y+2y=39
39-y=39
y=39-39=0
Plug y=0 into equation 1
x+0=13
x=0
Answer:
y = -1/3x - 5/3
Step-by-step explanation:
The slope of a line is the ratio of vertical distance to horizontal distance between the points. Since the line has to cross through the point (-5,0), count out the slope -1/3 by moving down 1 unit and to the right 3 units. This places the line between -1 and -2 on the y-axis. Looking at the options listed for b in y = mx + b. b = -5/3 is the best option and is between -1 and -2.
Answer:
Step-by-step explanation:
To solve this, you want to isolate h. Start by subtracting 9 from both sides: 16 = -3.2h. Divide by -3.2: h = -5
Answer:
Interior Angle Theorem
x=5
measure of angles: 46, 46, 134
Step-by-step explanation:
Interior angle theorem
12x-14=5x+21
7x=35
x=5
12x-14=12(5)-14=46
5x+21=5(5)+21=46
20x+34=20(5)+34=134
