Answer: 1 and 7/15
Step-by-step explanation:
I made the common donominator 15 and then did the problem but the donominator stays the same
1) Area of trapezoid =1/2(base 1 +base 2)* height
Answer:
Step-by-step explanation: The answer for 7: is 7/2
8: 28/5.
9: 9/4
10: 24/5
Answer:
(-1,1)
Step-by-step explanation:
x + 9y = 8
-6x - 9y = -3
Add the two equations together to eliminate y
x + 9y = 8
-6x - 9y = -3
---------------------
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = -1
Now solve for y by substituting into the first equation
x+9y = 8
-1 + 9y =8
Add 1 to each side
-1+1 + 9y = 8+1
9y=9
Divide each side by 9
9y/9 = 9/9
y = 1
Answer:
To determine if an equation is a linear function, it must have the form y = mx + b (in which m is the slope and b is the y-intercept). A nonlinear function will not match this form.
So it is linear.
