-7x-4y=18
y=-5x-24
solve for x and y (show work)
Answer:
ima answer it but first how do i show the work
Step-by-step explanation:
Answer:
(-6, 6)
x=-6, y=6
Step-by-step explanation:
The easiest way to solve for this is by substitution. This means substituting y with -5x-24 in the first equation. It gives you the same variables and is easy to work with.
1. Set up your equation: -7x-4(-5x-24)=18
2. Use the distribution property: -7x+20x+96=18
3. Add like terms: 13x+96=18
4. Subtract 96 from both sides: 13x=-78
5. Divide by 13 to get x alone: x=-6
Now that we have x, we can find y much easier by plugging in -6 for x.
1. Set up your equation: -5(-6)-24=y
2. Multiply: 30-24=y
3. Subtract: 6=y
Check your answers!
-7(-6)-4(6)=18
-5(-6)-24=6
There you go! Hope this helped :)

Explain how to find 40% of a number using friendly percents
Answer:
here's your solution
=> percent means divided by 100
=> to find 40% of a number ,
=> we have to think for a number here it
is not given
=> so, we have to assume it , then let the
number be X
=> now ,. equation= 40/100*x
=> 40/100*X
hope it helps
Four people applied for a job as an assistant manager at a store. Only two of these people will be hired.
Answer:
50% of the applicants will be hired.
Step-by-step explanation:
Given that four people applied for a job as an assistant manager at a store, but only two of these people will be hired, the following calculation must be performed to determine the percentage of people who will enter the job:
4 - 2 = 2
4 = 100
2 = X
2 x 100/4 = X
200/4 = X
50 = X
Thus, 50% of the applicants will enter the job.

1. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on
January 15th. Based on data taken in previous years, the snow pack decreases
about 11 inches a week after January 15th. What would be the rate of change?
Answer:
The rate of change is 10%
Step-by-step explanation:
The computation of the rate of change is as follows:
Given that as on Jan 15, the snow pack is 150 inches
And, the last year, it would decrease by 11 inches a week after jan 15
So, the rate of change is
= 15 ÷ 150
= 10%
. The average life of a certain type of small motor is 10 years with a standard deviation of 2 years. The manufacturer replaces free all motors that fail while under guarantee. If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer
Answer:
She should offer a guarantee of 13.76 years.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The average life of a certain type of small motor is 10 years with a standard deviation of 2 years.
This means that [tex]\mu = 10, \sigma = 2[/tex]
If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?
She should offer the 100 - 3 = 97th percentile as a guarantee, so X when Z has a pvalue of 0.97, that is, X when Z = 1.88.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.88 = \frac{X - 10}{2}[/tex]
[tex]X - 10 = 2*1.88[/tex]
[tex]X = 13.76[/tex]
She should offer a guarantee of 13.76 years.

Answer:
the book has 40 pages
Step-by-step explanation:
so he has read 90 percent and has 4 pages left. So 10 percent is 4 pages.
10 times 10 is 100. 4 times 10 is 40. The entire book is 40 pages.
10 percent equals 4 pages
20 percent percent 8 pages
30 percent is 12 pages
40 percent is 16 pages
50 percent is 20 pages
60 percent is 24 pages
70 percent is 28 pages
80 percent is 32 pages
90 percent is 36 pages
100 percent is 40 pages
solve the equation please
=========================================================
Work Shown:
Let x = log(y+2)
The given equation becomes
4x = 3x-log(13)
Solving for x leads to
4x-3x = -log(13)
x = -log(13)
Then substituting gets us
log(y+2) = -log(13)
log(y+2) = log(13^(-1)) .... use the rule that A*log(B) = log(B^A)
log(y+2) = log(1/13)
y+2 = 1/13 ................. used the rule if log(A) = log(B), then A = B
y = (1/13) - 2
y = (1/13) - (26/13)
y = (1-26)/13
y = -25/13 .... answer is choice E
For each step, the logs are the same base. The base doesn't matter. It can be base 10 or base 2 or base e. As long as the base stays consistent is all that matters. Also, the base cannot be 1, 0 or a negative number. The base can be any other real number.

HELP PLEASE WILL MARL BRANIEST IF right
Answer:
A bit of a doosy, but bare with me: f*g*h(x) = [tex]x^2+54x-12x\sqrt{x} -108\sqrt{x} +90[/tex]
Step-by-step explanation:
So explaining this is a bit awkward as well, but I can try...So
Starting from g(x) working that backwards into f(x), so...
g(x) = [tex]x-3[/tex]
f(x) = [tex](x^4+9)[/tex]
Take your g(x) and plug it into your f(x) into every x you see
f(g(x)) = [tex](x-3)^4+9[/tex] ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...
Now you still have one more step which you still need to include h(x), so
Remember h(x) = [tex]\sqrt{x}[/tex]
Now plug in your h(x) into every x you see from f(g(x)) and it should look like...
[tex](\sqrt{x} -3)^4 + 9[/tex]

The value of [tex]x[/tex] is 16.667.
Step-by-step explanation:
In this exercise, we know that the two triangles described in the figure are similar. If both are similar, the following ratio is constructed:
[tex]\frac{x}{25} = \frac{26}{39}[/tex] (1)
[tex]x = 16.667[/tex]
The value of [tex]x[/tex] is 16.667.

Answer:
1/7
Step-by-step explanation:
1/3 of 3/7 = 1/3 x 3/7
we can cancel out 3 and 3 because they are multipliers of themselves
so now it is 1/1 x 1/7 = 1/7
Or .
1/3 x 3/7 = 1x3/3x7 = 3/21 = 1/7
