Answer:
-3
Step-by-step explanation:
Answer:
x=2/5, y=-3. (2/5, -3).
Step-by-step explanation:
10x+3y=-5
-5x-4y=10
----------------
10x+3y=-5
2(-5x-4y)=2(10)
-------------------------
10x+3y=-5
-10x-8y=20
-------------------
-5y=15
y=15/-5
y=-3
10x+3(-3)=-5
10x-9=-5
10x=-5+9
10x=4
x=4/10=2/5
You’ll need to split the shape into 2 rectangles then find the area of both the rectangles and add them together.
30*10=300
20*10=200
area=500
Answer:
y=20x+25, this equation is linear, the rate of change is constant
Step-by-step explanation:
She starts with 25$, that doesn't change so its our constant. Let x represent each week. Each week she ears 20$
So, let y represent the total amount of money she has
y=20x+25, this equation is linear, the rate of change is constant
14 tens is equal to 140. You get this by multiplying 14 and 10. So the answer to your question is 140.
