Answer:
7,460
Step-by-step explanation:
Whole numbers are counting numbers like 0, 1, 2, 3, . . .. Whole numbers are positive integers including 0
When rounding a number to the nearest whole number, firstly check the first digit after the decimal point. If the first digit is less than 5 we don't round up, but if the first digit is 5 or greater we round up.
Given the number 7,459.82
We check, the first digit after the decimal point, since this digit is greater than 5 (i.e. 8) we round u to get 7,460
The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 3x + 1
How much more is the rate of change of function 2 than the rate of change of function 1? (5 points)
1
2
3
4
Answer:
The rate of change of function 1 = 0The rate of change of the function 2 = 3Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.
Step-by-step explanation:
Function 1
A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).
Given the points
(0, 3)(4, 3)It means
at x = 0, y = 3
at x = 4, y = 3
Since the y-values are same, it means the points lie on a horizontal.
The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).
Therefore, the rate of change of function 1 = 0
Function 2
y = 3x+1
comparing with the slope-intercept form
y = mx+b
here m is the rate of change or slope and b is the y-intercept
so the rate of change of the function 2 = m = 3
Conclusion:
The rate of change of function 1 = 0The rate of change of the function 2 = 3Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.

Step-by-step explanation:
a sales person at a jewelry store earns 3% commission each week. Last week, Heidi sold $680 worth of jewelry. How much did she mKe in commission? How much did the jewelry store make from her sales?
Heidi earned $20.4 in commission
The store made __ from her sales
Answer: $659.60
Step-by-step explanation:
Heidi commission = 3% * 680
= $20.40
The amount the Jewellery store made will be what she sold less the commission owed to her:
= 680 - 20.40
= $659.60
Given that the highest common factor (HCF) and the lowest common multiple (LCM) of 20 and p are 10 and 60 respectively.
Answer:
Value of p = 30
Step-by-step explanation:
Given:
Two number = 20 , p
Highest common factor (HCF) = 10
Lowest common multiple (LCM) = 60
Find:
Value of P
Computation:
Product of two number = HCF x LCM
20 x p = 10 x 60
20 p = 600
p = 600 / 20
Value of p = 30

The y value in the table gets multiplied by 4 every time the x value goes up by 1. You can check your work using the values in the table given to you. 0.25 times four is 1. 1 times four is 4, and so on as the table goes.
The ratio would be written as 1:4

Answer:
Step-by-step explanation:
ln(x-2)^5
ln(x + 3)^8
ln(x + 3)^3
(x - 2)^5 * (x + 3)^8
================ Cancel the (x + 3)s
(x + 3)^3

Find the solution set of the inequality. \qquad16x - 7 \leq -7116x−7≤−71
Answer:
[tex]x \le -4[/tex]
Step-by-step explanation:
Given
[tex]\qquad16x - 7 \leq -71[/tex]
Required
Solve
Start by adding 7 to both sides
[tex]\qquad16x - 7 + 7 \leq -71 + 7[/tex]
[tex]\qquad16x - 7 + 7 \leq -64[/tex]
[tex]\qquad16x \leq -64[/tex]
Divide both sides by 16

Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?
because if you add 18x to both sides of the equation and simplify, you get −18=−18
because if you add 18 x to both sides of the equation and simplify, you get - 18 = - 18
because if you add 18x to both sides of the equation and simplify, you get 0=−18
because if you add 18 x to both sides of the equation and simplify, you get 0 = - 18
because if you subtract 18x from both sides of the equation and simplify, you get −18=−18
because if you subtract 18 x from both sides of the equation and simplify, you get - 18 = - 18
because if you subtract 18x from both sides of the equation and simplify, you get 0=−18
Answer:
Because if you add 18x to both sides of the equation, you get 0 = -18
Step-by-step explanation:
When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.

A lent B rs 32500 to purchase a car at 12.5% p.A
Answer:
6,483.75
Step-by-step explanation:
Calculation to find the interest paid by B after 3/2 year
First step is to calculate the Compound interest amountUsing this formula
Interest paid= P(1 + r/100)^Time
Where,
P represent principal=32,500
r represent Rate of interest = 12.5%/2 = 6.25%
T represent Time=3/2 years
Let plug in the formula
Compound interest amount= 32,500(1 + 6.25/100)^2*3/2
Compound interest amount= 32,500([1+.0625)^3
Compound interest amount= 32,500(1.0625)^3
Compound interest amount= 32,500 *1.1995
Compound interest amount= 38,983.75
Now let calculate the Interest paid by B
Interest paid by B = 38,983.75 - 32,500
Interest paid by B = 6,483.75
Therefore the interest paid by B after 3/2 year will be 6,483.75

Step 1: Define
y = 3x - 2
Step 2: Rewrite
Add 2 to both sides: y + 2 = 3xDivide 3 on both sides: (y + 2)/3 = xRewrite: x = (y + 2)/3Answer:
x = [tex]\frac{y+2}{3}[/tex]
Step-by-step explanation:
Given
y = 3x - 2 ( add 2 to both sides )
y + 2 = 3x ( isolate x by dividing both sides by 3 )
[tex]\frac{y+2}{3}[/tex] = x

= In a 12-egg carton, 1/6 equals 2 eggs. Use the grids below to help you
und draw cartons where:
Answer:
given below
Step-by-step explanation:
These are fractions problems .
If you have 12 eggs and you need 1/6 then
12* 1/6= 12/6= 2 eggs
Similarly if you need 1/3,1/4, 1/2
12 * 1/3= 12/3= 4 eggs
12 * 1/4 = 12/4= 3 eggs
12 * 1/2 = 6 eggs
These can be drawn in sets of 12.
from the picture we see that dividing the 12 eggs in two parts and coloring one part gives 6 eggs.
Similarly dividng the 12 eggs in three parts and coloring one part gives 4 eggs.
The fractions 1/3,1/4,1/2 or 1/6 means dividing the 12 eggs into 3,4,2, or 6 parts and obtaining 1 part out of it.

-0.45x + 0.33 = -0.66
What is the solution?
x = -2.2
x = -1.4
x = 1.4
x = 2.2
Answer:
LAST ONE: x=2.2Step-by-step explanation:
-0.45x + 0.33 = -0.66
Hope this helps
Answer:
x = 11/5 or 2.2Step-by-step explanation:
-0.45x + 0.33 = -0.66 subtract 0.33 both sides
-0.45x = -0.66 - 0.33 simplify
-0.45x = -0.99 multiply both sides by 100
-45x = -99 divide -45 both sides
x = -99 / -45 simplify
x = 11/5 or 2.2

expression?
Answer:
d^5
Step-by-step explanation:
Given the indicinal expression
d^8/d^3
Based on the law of indices, if the base are the same, subtract the powers. This is as shown:
d^8/d^3 = d^{8-3}
d^{8-3} = d^5
Hence the solution is d^5

log (x2 - 1) - log (2x + 2) = 0
Answer:
x=3
Step-by-step explanation:
log (x^2 - 1) - log (2x + 2) = 0
Add log (2x + 2) to each side
log (x^2 - 1) = log (2x + 2)
Since the logs with the same base are equal the x^2 -1 must equal 2x+2
x^2 -1 = 2x+2
Subtract 2x+2 from each side
x^2 -1 -2x-2 = 2x+2 -2x-2
x^2 -2x-3 = 0
