Answer: (5,10)
Step-by-step explanation:
multiply first equation with 2 and add it to second to eliminate X
7x-5y=-15 //*2
14x-10y=-30
-14x+7y=0
----------------
-3y=-30
y=-30/-3
y=10
7x=50-15
7x=35
x=35/7
x=5
Answer:
Step-by-step explanation:
6/5 + 2x/5= y
3+ 5y/2 = x
Answer:
B
Step-by-step explanation:
A function has at least one output for each input. The inputs can share a number though. For C, it's wrong because one input cannot be used for 3 outputs and D is wrong because there is only one output but there needs to be at least one for each input.
Answer:
y= 4x+1
Step-by-step explanation:
y = mx + b
The b is the y-intercept, so to find it you just need to find where the line is on the y-axis when x is zero
The slope is just rise over run (y2-y1/x2-x1), so the graph in the picture shows us that the line goes up 4 to go over 1. Therefore the slope is 4/1 which is equal to 4.
lol sommet i would do lol but i didnt ahaha
Answer:
follow steps below --------------------------------------(down arrow)
Step-by-step explanation:
to work out the surface area you would do
base times height
length times width
height times width then add all together
