Solve the system of equation. Write the solution as a coordinate point
Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16
Answer:
(2,16)
Step-by-step explanation:
Step 1: Substitute -x+18 for y in y=8x:
-x+18=8x Add X to both sides
9x=18 Divide 9 by both sides
x=2
y=8(2)Plug in the new value for x(which is 2) into one of the equations
y=16

x^8-13x^4+36=0
Answer:
Step-by-step explanation:
a = x^4
a^2 - 13a +36 = 0
(a-4)*(a-9)=0
a = 4, a = 9
so
x^4 = 4, x^4 = 9
x = + or - 4th root of 9 and 4

Answer:
43 degrees
Step-by-step explanation:
A line is 180
180-86= 94
Since both angles are equal to each other. Split 94
94/2 = 47
90 degrees for the other side.
one triangle is 180 total.
add it up and subtract 180 to find the missing angle.
180 - 47+90 = 43

What is the Greatest Common Factor of the two monomials?
15a²b, 35ab2
Answer:
5ab
Step-by-step explanation:
To find the greatest common factor (GCF), you will need to find the largest value that both of these monomials can be divided by. There are three different parts to these monomials: the number value, variable a, and variable b.
Find the largest number of each element that can be divided by both.
Numbers: the GCF of 15 and 35 is 5 (15/5 = 3, 35/5 = 7, 3 and 7 are prime numbers and therefore, cannot be divided further)
Variable a: the GCF of a² and a is a
Variable b: the GCF of b and b² is b
Therefore, the GCF is 5ab.
5. Suppose Sal’s total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different
Answer:
Given:
Profit of every sandwich = $2
Profit of every wrap = $3
x = sandwich
y = wrap
Last month: 2x + 3y = 1,470
Next month: 2x + 3y = 1,593
Based on the given equation:
Both still have the same profit. $2 for sandwiches and $3 for wraps.
The only reason why there is a difference in the total amount is the change in the number of sandwich or wrap sold in a given month.
Since, next month's total sale is higher than last month's total sale, it is safe to assume that the sale of sandwich or wrap is higher than last month's sale.
The graph of the functions for the two moths are similar because both conditions have same slope and they are different because they have different [tex]y-[/tex] intercept.
What is slope intercept form?
The graph of the linear equation is a line with [tex]m[/tex] as slope, [tex]m[/tex] and [tex]b[/tex] as the [tex]y-[/tex] intercept. This form of the linear equation is called the slope-intercept form, and the values of [tex]m[/tex] and [tex]b[/tex] are real numbers.
It is given that, the profit amount is [tex]$\$2$[/tex] for each sandwich and [tex]$\$3$[/tex] for each wrap and total profit is [tex]$\$1593$[/tex].
So, the equation is,
[tex]2x+3y=1593[/tex]
Change the equation in slope intercept form [tex]y=mx+b[/tex]
So,
[tex]2x+3y=1593[/tex]
Subtract [tex]2x[/tex] in both sides.
[tex]2x+3y-2x=1593-2x[/tex]
[tex]3y=1593-2x[/tex]
Divide each side by [tex]3[/tex].
[tex]$\frac{3y}{3}=\frac{1593}{3} -\frac{2x}{3}[/tex]
[tex]$\therefore y=-\frac{2x}{3}+531$[/tex]
So, the equation is,
[tex]y=-\frac{2x}{3}+531$[/tex]
The graph of the equation is shown below.
From the below graph, we will have two step down and three step right.
So, slope looks like rise over run.
So, the graphs represents, how many wraps and sandwiches were sold.
Both will have same slope, because if we will make the equation for this, it is like,
[tex]$2x+3y=1593$[/tex]
The calculation is follow for both condition is same.
Since, both conditions have same slope but different [tex]y-[/tex] intercept.
Hence, next month's total sale is greater than last month's total sale, it is safe to consider that the sale of sandwich or wrap is greater than last month's sale.

Answer:
the last one
Step-by-step explanation:
A computer monitor has a width of 12 in. and a height of 9 in. What is the diagonal length of the monitor?
Answer:
15 in
Step-by-step explanation:
Using the formula d² = l² + w², we can substitute the numbers into their correct spots.
d x d = 9 x 9 + 12 x 12
d x d = 81 + 144
d x d = 225
Now we need to figure out what d is
15 x 15 = 225
So
15 squared = 9 squared + 12 squared
Meaning the answer is 15 in.
z=6x-y solve for x i need this for aleks
Answer:
(z+y)/6=x
Step-by-step explanation:
Solve for x: z=6x-y
Add y on both sides: z+y=6x
Divide by 6 on both sides (z+y)/6=x
Hope this helps plz mark brainliest if correct :D
The expression z = 6x - y can be written in terms of z and y as x = (z + y)/6, the answer is x = (z + y)/6.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
z = 6x - y
The linear expression is defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
To solve for x make the subject as x:
z + y = 6x
Divide by 6 on both sides:
x = (z + y)/6
Thus, the expression z = 6x - y can be written in terms of z and y as x = (z + y)/6, the answer is x = (z + y)/6.

The length of a room is 6.25 feet longer than the width, x. Write a expression that represents the perimeter of the room
Answer:
P=4x+12.5
Step-by-step explanation:
Step one:
given data
width W= x
Length L= (x+6.25)
We know that the perimeter of a rectangle is expressed as
P=2L+2W
P=2(x+6.25)+2(x)
P=2x+12.5+2x
collect like terms
P=2x+2x+12.5
P=4x+12.5
Hence the expression for the Perimeter is
P=4x+12.5
