x+10y
Step-by-step explanation:3x+2y+(-2x)+8y
First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + & - equals to -(minus) :-
3x-2x+2y+8y= x+10y
I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.
Hope it helpsWhy might you expect most absolute value equations to have two solutions? Why not three or four?
Answer:
If the absolute value expression is not equal to zero, the expression inside an absolute value can be either positive or negative. So, there can be at most two solutions. Looking at this graphically, an absolute value graph can intersect a horizontal line at most two times.

What is the value for X, Y, and Z?
Answer:
_________
z is 48
x is 48
y is 132
_________
Answer:
x+132=180 [ linear pair]
x=180-132=48
y=132[ opposite angles]
z=x=48 [ opposite angles]
if we add all these four angles we get 360 degree.

Solve the quadratic equation by completing the square.
x2 + 8x + 19 = 0
What’s the answer ? Math algebra 2
Answer: x= 4 ± [tex]\sqrt{-3}[/tex]
Step-by-step explanation:
[tex]x^{2}[/tex] + 8x + 19 = 0 First subtract 19 from both sides
-19 -19
[tex]x^{2}[/tex] + 8x = -19 Now to complete the square on the left side you will divide 8 by 2 and square the number that you will get and add it to both sides. If you divide 8 by 2 you get 4 and 4 squared is 16 .So add 16 to both sides.
x^2 + 8x + 16 = -19 + 16 Now factor the left side
(x+4)^2 = -3 Take the square root of both sides
(x+4) = ±[tex]\sqrt{-3}[/tex]
Subtract 4 from both sides
x = ±[tex]\sqrt{-3} - 4[/tex]
Explain how solving -7y > 161 is different from solving 7y > -161
Answer:
Sample response:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>
Which graph correctly shows the solution of the compound inequality 3x 2 -12 and 8x < 16?
Answer:
8x < 16 it shows the solution of the compound inequality
The area common to both the graph inequalities represent the solution set.
What is inequality? Differentiate between equation and expression? inequality : An inequality is used to make unequal comparisons between two expressions or numbers.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the compound inequality as -
3x > -12
and
8x < 16
Refer to the graph of the inequalities attached. The area common to both the graphs represent the solution set.
Therefore, the area common to both the graph inequalities represent the solution set.

Find the value of x of this triangle.
Answer:
12x
Step-by-step explanation:
Answer: x = 35°
Step-by-step explanation:
A triangle adds up to 180°. Therefore, the equation to find the value of x is 110+2x = 180.Subtract 110 on both sides. 2x = 70Divide by 2 on both sides. x = 35°Does anyone know the answer to this?

The formula a = m – n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon n. A. n = a + m B. n = m – a C. n = a – m D. n = – m – a
Answer:
n = m - a
Step-by-step explanation:
Given that:
The expression of the formula a = m - n
where;
a = actual cost of an item
m = original price
n = amount of coupon in dollars
The objective is to solve for the amount of the coupon.
In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.
So if a = m - n
a + n = m
n = m - a

Estimate the number of school-aged children in the city where the population is approximately 60,000, if 1 of every 10 citizens is a school-aged child. If 500 children can attend each school, about how many schools will the city need?
1 out of 10 are school aged.
Divide total population by 10:
60,000 / 10 = 6,000 are school aged.
Each school holds 500, divide school aged by 500:
6,000 / 500 = 12
They would need 12 schools.
The number of schools the city with the population 60,000 requires are 12.
Given that, the number of school-aged children in the city where the population is approximately 60,000.
In population 1 out of 10 are school aged.
Divide total population by 10
60,000/10 = 6,000 are school aged
Each school have 500 children, so the number of schools are
6,000/500 = 12
Therefore, the number of schools the city needs are 12.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The correct option is C.
What is a line segment?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. A line segment is a straight line with finite length, and thus, has two endpoints(points on either end).
The diagram for the given condition can be made as shown below. Now, from the image, the following conclusion can be made,
The two lines w and n are parallel to each other.The line m is perpendicular to n, this is because the angle between the two lines is equal to 90°. The two lines k and line n are also parallel to each other.Further, if all the options are observed.
A.) k Parallel to n and w Perpendicular to m
The first half of the given statement is correct but the second half of the equation is completely wrong. Therefore, not the correct option.
B.) k Parallel to n and w Perpendicular to m
The first half of the given statement is correct but the second half of the equation is completely wrong. Therefore, not the correct option.
C.) w Parallel to n and n Perpendicular to m
Since both the parts of the statement are correct, therefore, it can be concluded that the given statement is correct.
D.) w Parallel to n and w Perpendicular to m

Newton is thinking of a 6-digit number in which all of the digits are the same. The value of the digit in the thousands place is 8,000. What is Newton's number?
Answer:
Newton’s number is 888888
Step-by-step explanation:
Here, we want to write the Digit in which Newton is thinking of.
The information we have at hand is that, there are 6 numbers which are the same in this digits.
Now let’s look at the other information. The value of the thousand figure is 8,000. What this practically means is that the digit at the thousand place is simply 8.
Since all the digits are same, the digit he is thinking of will be 888888
