3) y = 4x + 24
y = x + 9

Answers

Answer 1

Answer:

x= -5

y= 4

Step-by-step explanation:

Substitute the equations for y

x+9=4x+24

Subtract x from both sides of the equation.

9=3x+24

Now subtract 24 from both sides of the equation.

-15=3x

x= -5

y= -5=9=4

Prove each of the following statements about integers by proving thecontrapositive of the statement.A. If 3nis even, thennis even.B. Ifx y zis odd, then at least one ofx; yandzis odd.

Answers

Answer and Step-by-step explanation:

(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.

(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

One-hour carbon monoxide concentrations in air samples from a large city average 12 ppm (parts per million) with standard deviation 9 ppm.

Required:
a. Do you think that carbon monoxide concentrations in air samples from this city are normally distributed.
b. Find the probability that the average concentration in 100 randomly selected samples will exceed 14 ppm.

Answers

Answer:

0.0132

Step-by-step explanation:

No

Carbon monoxide concentrations sample in air from a large city are not normally distributed. This is often so because of the time of the day and that of the night. There exists different concentrations during the day, with respect to during the night. The companies and factories work during the day, so does most vehicles. This means that there tend to be a higher concentration during the day, than there will be during the night.

b)

Assuming that Y' is approximately normal, we can say that

P(Y' > 14) = P(Z > [√100(14 - 12)/9]) and this is equal to

P(Z > 2.22) = 0.013

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly. How much would Brody need to invest, to the nearest hundred dollars, for the value of the account to reach $34,000 in 13 years?​

Answers

Answer:

21000

this is the answer

The value of the account is to reach $34,000 in 13 years with a rate of 3.7 compounded monthly is $ 21,000.

What is compound interest?

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly.

The rate of interest yearly will be

[tex]\rm Yearly \ rate = \dfrac{3.7}{12}\\\\Yearly \ rate = 0.308 \%[/tex]

The value of the account is to reach $34,000 in 13 years.

Amount (A) = $ 34,000

Time (t) = 13 years

Rate (r) = 0.308 %

Then the principal amount will be

[tex]\begin{aligned} A &= P (1 + \dfrac{r}{100})^{12*t}\\\\34000 &= P (1 + \dfrac{0.308}{100}) ^{13 * 12}\\\\34000 &= P (1.00308)^{156}\\\\P &= 21,044 \approx 21,000 \end{aligned}[/tex]

The principal amount is $21,000.

Step-by-step explanation:

First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:

2x + 8 + 6x + 12 = 180

Next, we can combine like terms to simplify the equation:

8x + 20 = 180

Now, we can subtract 20 from each side:

8x = 160

Finally, we divide both sides by 8 to find the value of "x":

x = 20

Jeff divided his 1,200 stamps equally among 7 stamp albums. Were there any stamps left over?
If so, how many?


Yes; there was 1 stamp left over.


Yes; there were 3 stamps left over.


Yes; there were 10 stamps left over.


No; there were no stamps left over.

Answers

Answer:

3 stamps were left over

Step-by-step explanation:

Division

When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.

But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.

Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.

1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.

How many?

Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over

of the rectangle in terms of x.

b. A= 2x - 2
A=x2 + 12x - 35
d. A=x? - 2x - 35

Answers

Answer:

A=x2 - 2x -35

Step-by-step explanation:

x+5 x-7

The solution is Option D.

The area of the rectangle is A = x² - 2x - 35

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the value of A is

The length of the rectangle L = x + 5

The width of the rectangle is W = x - 7

And ,

The area of rectangle = L x W

Substituting the values in the equation , we get

The area of rectangle = Length of rectangle x Width of rectangle

The area of rectangle = ( x + 5 ) ( x - 7 )

On simplifying the equation , we get

The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )

The area of rectangle A = x² - 7x + 5x - 35

The area of rectangle A = x² - 2x - 35

Therefore , the value of A is x² - 2x - 35

Hence , the area of rectangle is x² - 2x - 35

x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.

Step-by-step explanation:

2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2

(2x - 3) • 2 = x + 9

4x - 6 = x + 9 Add 6 to both sides

4x = x + 9 + 6

4x = x + 15 Subtract x from both sides

4x - x = 15

3x = 15 Divide 3 on both sides

x = 15/3
