Find the value of x
Answer:
x = 70
y = 110
z = 30
Step-by-step explanation:
all triangles add up to 180
30 + 80 = 110
180 - 110 = 70
x = 70
30 + 40 = 70
70 + 80 = 150
180 - 150 = 30
z = 30
40 + 30 = 70
180 - 70 = 110
y = 110

Describe the graph of y = -|x + 4| - 5.
Answer:
6
Step-by-step explanation:
The graph of the absolute value function is an inverted "V" such that the vertex is at (-4, -5) and opens downwards.
How to calculate the modular function?
Among modular functions, f(x) = |x| has its domain given by the real numbers and its range given by the positive real numbers. This is because the modular function will make |-y| = -(-y) = y given every negative y-value.
Given modular function is :
y = -|x + 4| - 5.
Hence, to plot the graph of a modular function, we need to determine some values for x and then apply them to the function f(x) = | x |.

At a local fitness center, members pay a $10 membership fee and $4 for each aerobics class.
Nonmembers pay $5 for each aerobics class. For what number of aerobics classes will the cost for
members and nonmembers be the same?
Qu
Thus, for aerobics classes, the cost will be the same for members and nonmembers.
(Type a whole number.)
Answer:
If both the members and nonmembers take 5 aerobics classes, they will have paid the same amount of money.
Step-by-step explanation:
To solve this problem, we can create a chart:
Step One: Where x equals the number of aerobics classes,
Members Nonmembers
Cost in Dollars 10+3x 0+5x
Step Two: We create an equation to solve for x.
Member Cost=Nonmember Cost
10+3x= 0+5x
Step Three: Solve for x:
10+3x= 5x Subtract 3 from both sides
10=5x-3x Combine like terms
10=2x
5=x
∴For five aerobics classes, the cost of members and nonmembers will be the same.

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+y=1
-2x -y=-4
Answer:
One solution:(1,2)
Step-by-step explanation:
y = x + 1
/Plug this in for variable y in equation [2]
-2x - (x +1) = -4
-3x = -3
Solve equation [2] for the variable x
3x = 3
x = 1
By now we know this much :
x = 1
y = x+1
Use the x value to solve for y
y = (1)+1 = 2

A triangle with a base of 4 centimeters and height of 3.5 centimeters. She found the area of the enlarged triangle. Her work is shown below. One-half (4) (3.5) (5) = 35 centimeters squared What was Beth's error? She should have divided One-half (4) (3.5) by 5. She should have divided One-half (4) (3.5) by 5 squared. She should have multiplied (4) (3.5) by 5. She should have multiplied One-half (4) (3.5) by 5 squared.
Answer: She should have multiplied One-half (4) (3.5) by 5 squared.
Step-by-step explanation:
The calculation of Beth is wrong. Since Beth enlarged the triangle below by a scale of 5, she should find the area of the traingle and then multiply by 5².
This will be:

The sum of 28 consecutive odd positive integers is a perfect cube. Determine the smallest possible set? What is the first and last terms in the sequence. Plz helppp!
Answer:
71 + 73 + ..... + 125 = 2,744 = [tex]14^{3}[/tex].
Step-by-step explanation:
The smallest set starts at 71. The last term is 125.
The total is 2,744, which is [tex]14^{3}[/tex].
The smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.
What is airthmatic sequence?Geometric sequence is the sequence in which the next term is obtained by adding or substracting the previous term with the same number for the whole series.
The sumation of airthmatic sequence is find out using the following formula.
[tex]S=\dfrac{n}{2}(a+l)[/tex]
Here, (a) is the first term of the sequence, (l) is the last term and (n) is the number of terms in sequence.
Let x is the first and the smallest term of the set. This set consists 28 consecutive odd positive integers. Thus, the sum of this set will be,
[tex]\sum=x+(x+2)+(x+4)+...+(x+54)\\\sum=28x+(2+4+6+....+54)\\\sum=28x+[\dfrac{27}{2}(2+54)]\\\sum=28x+756\\\sum=28(x+27)\\\sum=2\times2\times7(x+27)[/tex]
Now here 7 is prime number. The value of (x+27) should be perfect square of 7 and 2 to make it perfect cube. thus,
[tex]x+27=7^2\times2\\x=98-27\\x=71[/tex]
Put this value to find the sequence as,
[tex]71,71+2,71+4......,71+34\\71,73,75,.......125[/tex]
The first term in this set is 71 and last term is 125.
Hence, the smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.

A line contains the points (4,4) and (5,2). What is the equation of the line
that contains these two points?
Answer:y=-2/1x+12
Step-by-step explanation:
To find slope you need to use slope formula (y2-y1)/(x2-x1)
(2-4)/(5-4)
-2/1 is our slope
Now we need the y-int
Y=-2/1x+b
Take one of the given points and apply it to our equation
2=-2/1(5)+b
2=-10/1+b
2=-10+b
Add 10 to each side
12=b
Our final equation is
y=-2/1x+12

Answer
x=6, y=21/2
Explanation
The 86 degrees is just to make you confused.
Since this is a congruent triangle, you can just follow these steps.
Line AB: To get from 4 to 6, you multiply by 1.5.
Line BC: Divide 9 by 1.5 to get x. 9 divided by 1.5 is 6.
Line AC: Multiply 7 by 1.5 to get y. 7 times 1.5 is 10.5.
So the correct answer is the first choice; x=6, y=21/2 (this is also 10.5).
Mr.Williams, a parking lot owner, sold 20% of his lot to his neighbor. Later that year he sold 20% of the remainder of his lot to another neighbor. What percent of Mr.Williams' original parking lot does he still own?
Answer: He still owns 64% of the Mr.Williams' original parking.
Step-by-step explanation:
Let x = Area of the original parking plot.
First he sold 20% of his lot to neighbor .
Sold plot = 20% of x = 0.20x [Replace 'of' by '×' and divide number by 100 to remove %]
Reminder= x-0.20x= (1-0.20)x=0.80x
Again he sold 20% of the remainder .
Sold plot = 20% of (0.80x) = 0.20 (0.80x)
= 0.16x
Remainder plot = 0.80x-0.16x= 0.64x
Percent of Mr.Williams' original parking lot does he still own = [tex]\dfrac{0.64x}{x}\times100=64\%[/tex]
Hence, he still owns 64% of the Mr.Williams' original parking.
