Answer:
The answer is
<h2>3x - 10</h2>
Step-by-step explanation:
(5x - 3) - (2x + 7).
<u>Remove the brackets</u>
That's
5x - 3 - 2x - 7
<u>Group like terms and simplify</u>
That's
5x - 2x - 3 - 7
We have the final answer as
<h3>3x - 10</h3>
Hope this helps you

1/4 * 1/8 * -1024
= 1 / ( -32)
= -1/32
C
Answer:
10
Step-by-step explanation:
Rounding to the nearest 100 miles gives you 800 and rounding to the nearest 10 miles gives you 790.
1)
A)
f(x) has a slope of +5 (change with each x step), g(x) of +2 (m of y=mx+b), so f(x) rises 2.5 times faster than g(x)
B)
y intercepts are at x=0
f(x) has its intercept at -10
for g(x) it is the b value of y=mx+b, so 8
so the g(x) intercept is greater/above the one of f(x)
2)
A)
y intercept is at x=0 -> 12
When we started measuring the bird was already 12 miles away from its nest.
B)
average rate=(f(3)-f(1))/(3-1)
=16/2=8 [mph]
The bird moved on average with a speed of 8mph away from the nest.
C)
f(x)=8x+12
insert the 172 miles distance:
172=8x+12
160=8x
20=x
so after 20 hours it would be at a distance of 172 miles
this means we know the value from x=0 to 20 so its domain is/it is defined for x values of [0,20]
3)
A)
f(2)=225
f(5)=480
calculate slope m:
m=(f(5)-f(2))/(5-2)=(480-225)/3=255/3=85$/day
b=f(0)=f(2)-2*m=225-2*85=55
y=85x+55
B)
f(x)=85x+55
C)
Your x label is the amount of days rented, the y label the total cost/rent to pay, because y has larger values decide on some scale and the range of x values you want to draw, which should be x>=0.
Draw the points which were given, (2,225) and (5,480) and draw a line through them from one end of the diagram to the other.
Answer:
21x+4
Step-by-step explanation:
X’s: 21x
#’s: 4
So it will be 21x+4
