2x+4y+3z=6
x-2y+z=-5
-x-3y-2z=-7
solve for x,y,z
Answers
Answer:
x = -7 2/3, y = 1 1/3 and z = 5 1/3.
Step-by-step explanation:
2x+4y+3z=6 ..... 1
x-2y+z=-5 ...... 2
-x-3y-2z=-7 .......3
Add equations 2 and 3 to eliminate x:
-5y - z = -12 .....4
Multiply equation 2 by - 2:
-2x + 4y - 2z = 10
Add this to equation 1:
8y + z = 16 ........ 5
Now add equation 4 to equation 5:
3y = 4
y = 4/3 = 1 1/3.
Now find z by substituting for y in equation 4:
-5(4/3) - z = -12
z = 12 - 20/3
z = 36/3 - 20/3 = 16/3 = 5 1/3.
Finally, we find x by substituting for y and z in equation 1:
2x + 4*4/3 + 3*16/3 = 6
2x = 6 - 16/3 - 16
2x = 18/3 - 16/3 - 48/3 = -46/3
x = 23/3 = 7 2/3.

An adult elephant that is 9 ft tall casts a shadow that is 3 ft long. Find the length of the shadow that a 24 ft tree casts and explain your answer.
Answers
Answer:
8 feet
Step-by-step explanation:
First, we need to look at the relationship between the elephant and its shadow. The elephant is 9 ft tall and the shadow is 3 ft long, making the elephant 3 times larger than the shadow. Using this information, we can assume that the tree is 3 times larger than its shadow. To find the answer, divide 24 by 3, giving you a final answer of 8 feet long.
24 / 3 = 8

Graph the given inequality.
-3 > n
How do I do this?
Answers
-3 > n is the same as n < -3 after you flip both sides and flip the inequality.
To graph this, we place an open hole at -3 on the number line. Then we shade to the left to indicate all values smaller than -3. The open hole says "the endpoint is not included". This is because -3 is not smaller than itself.
We would have a filled in circle if we had "or equal to" as part of the inequality, but we don't.
The graph is shown below.

evaluate the function for f(-3), f(x)=3x+5
Answers
Answer:
-4
Step-by-step explanation:
Since we know that -3 takes the place of x in f(x), we can sub in -3 for all x's in the equation.
Using this information, we now have F(-3)=3(-3)+5
Once you solve the right side of the equation, you get f(-3)=-4
if you were to plot this, the points would be (-3,-4), however I believe you're not trying to, so the answer would be -4.
Jackson Elementary School ordered 25 pizzas for an awards ceremony. At the end of the day, the principal found 8 1/4 pepperoni pizzas and 7 3/4 sausage pizzas left over. What is a reasonable estimate for the number of pizzas the students ate at the awards ceremony?

Step-by-step explanation:
From the question, we are informed that Jackson Elementary School ordered 25 pizzas for an awards ceremony and at the end of the day, the principal found 8 1/4 pepperoni pizzas and 7 3/4 sausage pizzas left over.
A reasonable estimate for the number of pizzas the students ate at the awards ceremony will be:

substitute: -3 + 1/2-0
then, solve: -2/2 = -1
so the slope (m) = -1
next, pick any point (i’m going to use (0,-1)) and plug that in along with the slop into the point slop formula: y-y1 = m(x - x1)
y + 1 = -1(x - 0)
then, just solve
y + 1 = -x + 0
y = -x -1
ANSWER: y = -x -1

Are the ratios equivalent? 2/3 and 8/12 Explain.
Answers
Answer:
Yes.
Step-by-step explanation:
2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.
If two ratios are equal then the ratios are said to be in proportion and equivalent.
The ratios 2/3 and 8/12 are equivalent.
The simplest form of both ratios is 2/3.
What is a ratio?The ratio is the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
If two ratios are equal then the ratios are said to be in proportion and the ratios are said to be equivalent.
We have,
Two ratios:
2/3 and 8/12
We will make the ratios in their simplest form:
2/3 is in the simplest form.
8/12 = 4x2/4x3 = 2/3 is the simplest form.
We see that both the ratios are equal so the ratios 2/3 and 8/12 are in proportion.
Thus,
The ratios 2/3 and 8/12 are equivalent.
The simplest form of both ratios is 2/3.

Answers
Given:
A local carpenter uses the function f(x) to determine the amount earned after selling x number of book cases.
[tex]f(x)=180x[/tex]
He has to sell between 5 and 10 bookcases each month in order to meet his sales goal.
To find:
The domain for this situation.
Solution:
We have,
[tex]f(x)=180x[/tex]
where, f(x) is the amount earned be carpenter after selling x number of book cases.
Domain is the set of input values.
Here, input values are number of books he has to sell, which can be a fraction value.
Since, he has to sell between 5 and 10 bookcases each month in order to meet his sales goal, therefore the x values must be integers between 5 and 10.
Therefore, the domain for this situation is set of integers between 5 and 10, i.e., {5,6,7,8,9,10}.
