8(5g+5−2) Distributive Property to simplify the expression.
Answer:
= 40g -24
Step-by-step explanation:
you would multiply everything in the bracket by 8 to expand this
e.g.
(8x5g )+ (8x5 )+ (8 x -2)
= 40g + 40 - 16
now simplify by subtracting the like terms
= 40g -24

(c^3b^1a^4)^4 + 3a^16b^4c^12
Answer: 4a16b4c12
Step-by-step explanation:
A circle has a radius of 9 cm.
Work out the area of the circle.
Give your answer in terms of pi.
Radius = 9cm
So,
Area of circle = πr²
= π(9)²
= π × 81 cm²
= 81π cm²
Answer:
254.469 cm
Step-by-step explanation:
area = πr^2
π × 81 = 254.469005 rounded to 254.469 cm
in other terms, 81π cm^2

Joseph plots the speed of his car and time on a scatter plot. The equation for the line of best fit on his scatter plot is y = -15x + 60, where x is the time in hours and y is the speed in miles/hour. Which statement describes the situation correctly?
A.
The initial speed is 60 miles/hour, and his speed decreases by 15 miles/hour every hour.
B.
The initial speed is 60 miles/hour, and his speed increases by 15 miles/hour every hour.
C.
The initial speed is 0 miles/hour, and his speed increases by 15 miles/hour every hour.
D.
The initial speed is 5 miles/hour, and his speed increases by 30 miles/hour every hour.
Answer:
A
Step-by-step explanation:
His speed change is the slope or -15, decreases by 15 miles/hour
when he starts, his speed is 0*-15+60 = 60 miles/hour

Hope I helped! Have a nice day! Plz mar as brainliest!!! :D
-XxDeathshotxX
Answer:
This is a nonrigid transformation called a dilation.
Step-by-step explanation:
A dilation is when a pre-image's dimensions are altered in proportion with the pre-image. The image has a proportional relationship with the pre-image. The shape can get larger or smaller in size.
11. Carlos put $100 in a savings account at the beginning of the year. At the end of each month, he added $15 to the account. Ana put $400 in her savings account at the beginning of the year.

X ÷ 7 - 6 = 8
Is your expression.
HURRY PLEASEEEEE I RLLY NEED THISSS
Answer:
Option 2
Step-by-step explanation:
Given function:
x=8 and y=6x=5 and y=20Option 1: ×
Table one: y=8-6
if y is 6 then 8-6 can’t be 6 it is 2.
Option 2: √
Table one:
y=8-2
y would be 6 then this would be correct..
Table two:
y=4x
if y=20 then x would be 5 and if y is 16 then x=4.
Option 3:×
y=4x
this is wrong since table 2 is y=4x..
Option 4:×
Table one
y=x-4
if y is 6 and x is 8 then this is wrong..
Therefore, option 2 is correct..

Which of the following expressions is correctly written in scientific notation?
Answer:
The third one
Step-by-step explanation:
The points (2, 3) and (3, 6) fall on a particular line. What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=3x-3
Step-by-step explanation:
insert the first point into y=mx+b
3=2m+b
----------------
Do it again with the other point
6=3m+b
-------------
Now put both equations in a system of equations
3=2m+b
6=3m+b
solve for m and b
m=3 and b=-3
y=3x-3
m=slope
b=y-intercept
what is the distance between (0.-3) and (9.6)
Answer:
d = 12.7 when rounded to the nearest tenths
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (0, -3) and (9, 6)
d=√((9-0)²+(6-(-3))²)
d=√((9))²+(6+3))²)
d=√(81 + (9)²)
d = √162
d = 12.727...
d = 12.7 when rounded to the nearest tenths
