Simplify 10^4 to 10000
8.5x10000-3.0x10^3
Simplify 8.5x*10000 to 85000x
85000x-3.0*10^3
Simplify 3.0x10^3 to 3*10^3
Answer 85000x-3*10^3
Answer:
The scale drawing is 20 units by 4 units
Step-by-step explanation:
20/5 = 4
100/5 = 20
She paid $ 4 for renting a video game for 4 days...that means she paid $ 1 per day.
A horizontal axis is labeled days, a vertical axis is labeled cost of rental.
(x,y)...x is gonna be ur days and y is gonna be ur cost of rental
ur equation is gonna be y = x
points are plotted (1,1) , (2,2), (3,3)
^^ this is the graph u use ...graph B
First do inside the parenthesis first.
When dividing two exponents subtract them.
15-5 = 10
So w^15 / w^5 becomes w^10
Now you have (w^10)^4
Now multiply the exponents:
10 x 4 = 40
Final answer is w^40
Answer:
Step-by-step explanation:
given ,
equation y=ax²+bx+c
passing through points (1,6), (3, 20), and (−2,15).
then these points will satisfy the equation
at (1,6)
y = a x²+b x+c
6 = a(1)² + b (1) + c
a + b + c = 6------(1)
at (3 , 20)
y = a x²+b x+c
20 = a(3)² + b (3) + c
9 a + 3 b + c = 20------(2)
at (−2,15)
y = a x²+b x+c
15 = a(-2)² + b (-2) + c
4 a -2 b + c = 15------(3)
solving equation (1),(2) and (3)
a = 6 - b - c
9 (6 - b - c)+ 3 b + c = 20
6 b + 7 c = 34-------(4)
4 (6 - b - c) -2 b + c = 15
2 b + c = 3----------(5)
on solving equation (4) and (5)
