g(x) =
*+
+7
What is the average rate of change of g over the interval —2, 4):
Answer:
[tex]Rate = 1[/tex]
Step-by-step explanation:
Given
[tex]g(x) = x + 7[/tex]
Interval: (-2,4)
Required
Determine the average rate of change
This is calculated using:
[tex]Rate = \frac{g(b) - g(a)}{b-a}[/tex]
Where:
[tex](a,b) = (-2,4)[/tex]
So, we have:
[tex]Rate = \frac{g(4) - g(-2)}{4-(-2)}[/tex]
[tex]Rate = \frac{g(4) - g(-2)}{4+2}[/tex]
[tex]Rate = \frac{g(4) - g(-2)}{6}[/tex]
Calculate g(4) and g(-2)
[tex]g(4) = 4 + 7 = 11[/tex]
[tex]g(-2) = -2 + 7 = 5[/tex]
So:
[tex]Rate = \frac{11 - 5}{6}[/tex]
[tex]Rate = \frac{6}{6}[/tex]
[tex]Rate = 1[/tex]
Hence, the average rate of change is 1

Two trains, Train A and Train B, weigh a total of 389 tons. Train A is heavier than Train B. The difference of their weights is 263 tons. What is the weight of each train? Equation 1: ____________ Equation 2: ___________ Train A weight: ________ Train B weight: ________
9514 1404 393
Answer:
A + B = 389A - B = 263A = 326 tonsB = 63 tonsStep-by-step explanation:
The first equation is an expression of the first given relationship:
A + B = 389 . . . . . . where A and B represents trains weights, respectively
The second equation is an expression of the relationship described in the next two sentences:
A - B = 263
__
These equations can be solved by adding them together:
(A +B) +(A -B) = 389 +263
2A = 652 . . . . . . simplify
A = 326 . . . . . . . .divide by 2*
B = 326 -263 = 63
Train A weighs 326 tons.
Train B weighs 63 tons.

If an investment account starts with $3,900, and grows with 2.1% interest, compounded annually, how much is the account worth after 15 years?
Round your answer to the nearest dollar.
Do NOT round until you have calculated the final answer.
Answer 5327
Answer:
$5327
Step-by-step explanation:
Use the formula for calculating compound interest
A(t)=P(1+r/n)^n⋅t,
where A(t) is the balance of the account, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded each year, and t is the time (in years). We are given that P=$3,900, r=0.021, n=1, and t=15. Substituting the values into the formula and using a calculator to evaluate, we find
A(t)=P(1+r/n)^n⋅t = $3,900(1+0.0211)^(15)(1) ≈ $5,326.61
So the final answer is $5,327.
Answer: 5327
Step-by-step explanation:
Use the formula for calculating compound interest
A(t)=P(1+rn)n⋅t,
where A(t) is the balance of the account, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded each year, and t is the time (in years). We are given that P=$3,900, r=0.021, n=1, and t=15. Substituting the values into the formula and using a calculator to evaluate, we find
A(t)=P(1+rn)n⋅t=$3,900(1+0.0211)(15)(1)≈$5,326.61
So the final answer is $5,327.

-4x = 7y + 13
Find the slope of the line
Answer:
-4/7
Step-by-step explanation:
The first step of this problem would be changing the format of the equation so that it fits into slope-intercept form.
-4x = 7y + 13
-4x -7y = 13 (subtract 7y from both sides)
-7y = 4x + 13 (add 4x to both sides)
7y = -4x -13 (divide both sides by -1)
y = -4/7x - 13/7 (divide both sides by 7)
Now that it is in slope-intercept form, finding the slope is simple as long as you know what to look for.
Remember that y is simply a variable, just because it is at the beginning of the equation does not mean -4/7x - 13/7 is the answer. The question is asking specifically for the slope of the line. Slope in this equation is m. If y = mx + b, then m = -4/7.
The slope of the line is -4/7.

HELP Increase 1 by 10%
Answer:
1.1
Step-by-step explanation:
Answer:
The answer is 1.1
Step-by-step explanation:
To increase 1 by 10%, you have to do this:
1 * 10% = 0.1
The 0.1 is what 10% of 1 is.
You then add that 0.1 to the 1:
0.1 + 1 = 1.1
And that is how you get the answer.

Step-by-step explanation:
Imagine you are hanging two identical picture frames. Each frame is 28 inches wide and the wall you are hanging them on is 10 feet wide. There needs to be 8 inches of space in between the two frames. How far do the frames need to be from the left and right side of the walls in order to be centered?
Answer:
28 inchesStep-by-step explanation:
Sum of the width of the two frames and a gap between them:
28*2 + 8 = 64 inThe gaps from the left and right are equal to x:
x = (10 feet - 64 in)/2 = (120 in - 64 in)/2 = 28 inAny one know the answer for these two it’s OK if you can only do one
Answer:
3) 10
4) 12
Step-by-step explanation:
It’s the Pythagorean Theorem.
3) 6²+8²=c²
36+64=c²
100=c²
√100=c
c=10
4) 7.2²+9.6²=c²
51.84+92.16=c²
144=c²
√144=c
c=12
Answer:
c = 10km
Step-by-step explanation:
This is for #3.
Pythagoream Theoreom formula: a^2 + b^2 = c^2
Plug in the numbers into the formula and simplify.
8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
√100 = 10
c = 10km

Which statement correctly identifies a point on the graph of f–1(x)?
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
Answer:
The point (4, –7) is on the graph of f(x), so the point (7, –4) will be on the graph of f–1(x). (quick answer A)

solve the systems of equations y=2x and y=-x - 6
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4
Hope this helps :)
120 coins what is the ratio if 2/6 is nickels and 2/6 are dimes and the rest is quarters. What is the ratio of nickels to dimes to quarters?
Hi there!
If the nickels and dimes ratioe are both 2:6, then the quarter is also 2:6.
The total of of all together is also 6:6 and 6:6 is also 120 coins.
120 divide by 3 different kinds of coins are 40.
This means that there are 40 of 1 coin out of 3 different kinds of coins. What I really mean is that each coins all have 40 each...
Therefore, the ratios of nickels to dimes and to quarters are 40:40:40...
List three factors that must be considered when designing and building a house? Describe how each factor can influence the design and the building of the house.
I will be giving brainiest to correct and best explained answer! :)
Step-by-step explanation:
I would say the area its getting built. imagine wanting to build a house but you can't dig the sewer (if thats the spelling) pipes bc the area you want doesn't have any water or something like that. definitely money. without it, you can't do anything, you can't buy materials or even hire people to help you because you cannot tell me that you can build a house on your own. Another I would say is Labor cause like I said, if you ain't got nobody to help you, you're probably going to take a few years or more. so if you want to build a house in an area where there is a few architects and designers, you're just going to have to suck it up and get what you get.
