Answer:

x = 2

Step-by-step explanation:

10x + 1 = 2(3x + 5) - 1

mutlipy the 2 to the 3x and the 5
you should get 10x + 1 = 6x + 10 - 1
now you have to add the combine terms
so it will now be 10x + 1 = 6x + 9
now you.have to get the x's on one side and the constants (numbers alone) on the other side
so you can subtract the 6x on both sides
once you do that you wil get 4x + 1 = 9
After you get this equation you will have to subtract the one from both sides.
you will get 4x = 8
All you have to do it divide 4 on both sides. Your final answer is x = 2.

Answer:

x=2

Step-by-step explanation:

First expand 2(3x+5)

6x+10

Which will give you,

10x+1=6x+10-1

then subtract 6x to both sides

4x+1=10-1

then subtract 1 to both sides

4x+2=10

then subtract 2 to both sides

4x=8

then divide them both by 4

x=2

Find the simple interest earned in a savings account that pays 5% interest if $500 is deposited for 4 years. A. $100, B. $1000,

g100num [7]

To calculate simple interest, you first need to multiply the original amount by the percentage of the money which is going to be added.

In this situation, 500 x 0.05 is the interest which will be added each year.
Therefore, $25 will be added each year. Since it is over 4 years, it is (25*4).
So the account will have earned $100 of simple interest.

Although the account will contain $600, it will have EARNED $100 of interest since it started with $500 already.

Answer - A $100 of simple interest will be earned.

ecn 221 The sodium content of a popular sports drink is listed as 206 mg in a 32-oz bottle. Analysis of 14 bottles indicates a s

spayn [35]

Answer:

$H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 206 mg

Sample mean, $\bar{x}$ = 217.5 mg

Sample size, n = 14

Sample standard deviation, s = 14.9 mg

Claim:

The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.

Thus, we design the null and the alternate hypothesis

$H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}$

We use two-tailed t test to perform this hypothesis.

Answer:

Part a)

We need to find the equation of a straight line passing through two given points in slope-intercept form

Part b)

The information given; we are given two points where the line passes through; (0, -4) and (-2, 2)

Part c)

We shall first determine the slope of the line using the formula;

change in y/change in x. Next, we determine the value of the y-intercept using the general form of the equation of a straight line in slope-intercept form; y = mx+c

Part d)

The slope of the line is calculated as;

(2--4)/(-2-0) =6/-2 = -3

The equation of the line in slope-intercept form becomes;

y = -3x +c

We use the point (0, -4) to determine the value of c;

-4 = -3(0)+c

c = -4

Part e)

Final solution thus becomes;

y=-3x-4
