4x + 6y - z=-18
3x +2y - 4z = -24
- 5x + 3y + 2z = 15
find x y and z
Answer:
x = -2, y = -1, z = 4
Step-by-step explanation:
4x + 6y - z=-18
z = 18 + 4 x + 6 y
3x +2y - 4z = -24
z = 6 + (3x)/ 4 + y /2
- 5x + 3y + 2z = 15
z = 15/2 + (5x)/2 - (3y)/2
18 + 4 x + 6 y = 6 + (3x)/ 4 + y /2 = 15/2 + (5x)/2 - (3y)/2
x = -22y/13 - 48/13
4(-22y/13 - 48/13) + 6y - (15/2 + (5(-22y/13 - 48/13))/2 - (3y)/2) = -18
Compute the output value of the variables x and y with respect to the input values of x, y, and z coefficients.

What is an equation of the line that passes through the point
(6,7) and is parallel to the line
2x−3y=9?
Answer:
The equation of line parallel to given line passing through (6,7) is: [tex]y = \frac{2}{3}x+3[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]2x-3y = 9[/tex]
We have to convert the equation in slope-intercept form. The slope-intercept form is given by:
[tex]y= mx+b[/tex]
Adding 3y on both sides and subtracting 9 from both sides
[tex]2x-3y+3y-9 = 9+3y-9\\2x-9 = 3y\\3y = 2x-9[/tex]
Dividing whole equation by 3
[tex]\frac{3y}{3} = \frac{2x-9}{3}\\y = \frac{2}{3}x - \frac{9}{3}\\y = \frac{2}{3}x-3[/tex]
Let m be the slope of given line then
m = 2/3
Let m1 be the slope of line parallel to given line. Slopes of two parallel lines is equal that means:
m = m1 = 2/3
The equation of line will be:
[tex]y = m_1x +b\\y = \frac{2}{3}x+b[/tex]
Putting the point (6,7) in equation
[tex]7 = \frac{2}{3}(6) +b\\7 = 2(2) +b\\7 = 4+b\\b = 7-4\\b = 3[/tex]
Putting the value of b
[tex]y = \frac{2}{3}x+3[/tex]
Hence,
The equation of line parallel to given line passing through (6,7) is: [tex]y = \frac{2}{3}x+3[/tex]

What is the equation of a line parallel to y=7x-8 that passes through (5, 22)?
Answer:
y = 7x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 8 ← is in slope- intercept form
with slope m = 7
Parallel lines have equal slopes, thus
y = 7x + c ← is the partial equation
To find c substitute (5, 22) into the partial equation
22 = 35 + c ⇒ c = 22 - 35 = - 13
y = 7x - 13 ← equation of parallel line
A factory makes 300 sheets of construction paper per hour. How many sheets of construction paper will the factory make in 2 hours?
Answer: 600 sheets
Step-by-step explanation:
300/1 -> 300 sheets per 1 hour
To find the number in two hours, multiply the numerator and the denominator by 2.
300 x 2 = 600
1 x 2 = 2
Thus, the factor makes 600 sheets in 2 hours.

Which point is the y-intercept of the line represented by the equation y-3=13(x+6)?
(0,9)
(0,5)
(5,0)
(0,2)
Answer:
The equation for a zero slope line is one where the X value may vary but the Y value will always be constant. An equation for a zero slope line will be y = b, where the line's slope is 0 (m = 0).
The y-intercept of the equation will be at (0, 81). Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 3 = 13(x + 6)
Convert the linear equation into slope-intercept form. Then the equation is written as,
y - 3 = 13x + 78
y = 13x + 78 + 3
y = 13x + 81
The y-intercept of the equation will be at (0, 81). Then the correct option is A.

Write the decimal as a fraction or mixed number in simplest form.
9.75
✨Answer:✨
9 3/4 (simplest form)
✨Step-by-step explanation:✨
1. Convert decimal into fraction:
9.75 = 975/100
2. Simplify:
975/100 = 39/4 = 9 3/4
A. Reduce fraction to lowest terms (25 is the greatest common divisor of 975 and 100. Reduce by dividing both numerator and denominator by 25):
975/100 = 975 ÷ 25 = 39/4
100 ÷ 25
B. Convert improper fraction to mixed number:
39/4 = 9 3/4
(39 ÷ 4 = 9 remainder 3)

Tracy is borrowing $10,700 on a six-year, %, add-on interest loan. What will Tracy's monthly payments be?
Answer:
Step-by-step explanation:
Use the formula I=prt. (Interest = principle x rate x time)
So, I = 10700 x 0.07 (7% as a decimal) x 6
So, I = 749(6)
I = 4494
Now, divide 4494 by 6(12)
4494/71
This = 63.3 dollars.
Therefore, she is paying 63 dollars per month.
Tracy's monthly payments is $62.41.
What is Simple Interest?The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.
Amount (A) = Principal (P) + Interest (I)
and, Simple Interest = PRT/100
Given:
P= 10700
Time= 6 year
Interest = 7%
Now, using simple interest
SI = P x R x T/100
SI = (10700 x 0.07 x 6)
SI = $4494
So, Tracy's yearly payments
= 4494/6
= 749
and, Tracy's monthly payments
= 749 / 12
= 62.41
Hence, Tracy's monthly payments is $62.41.
