Answer:
150$
Step-by-step explanation:
In order to find the answer to this question you must find twenty-five percent of two-hundred.
50% of 100 = 50
100% of 100 = 100
100% of 200 = 200
50% of 200 = 100
25% of 200 = 150
= 150$

x^2- 11 = 70 I need help on how to solve this
Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ([tex]\sqrt{x}[/tex] this symbol). When you do that, you should get what x is! Let me know if you still need help!

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. Type your answer in the box provided or use the upload option to submit your solution.
Answer:
y = x - 1
Step-by-step explanation:
If it's parallel to x - y = 7, that means the slope of that equation is the slope for the equation you're looking for.
To get the slope, you need to put the given equation into slope intercept form, so move x to the other side. You should get: -y = 7 - x
Then, to get the y positive, divide by -1: y = -7 + x
Slope intercept form is as follows: y = mx + b, so whatever the number is in front of x is your slope. In this instance, your slope is 1.
You now have your slope, and a point in which your new line passed through. Using slope intercept form, y = mx + b, if you substitute in what you know, you can find your answer. Right now you know y, m, and x, and you're looking for b.
x=1; y=0; m=1.
So, substituting, you'd get 0 = (1)(1) + b
0=1+b Solve
You should get b= -1, leaving your final answer as y = x - 1
y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.
The slope will be same as it is parallel.
x - y = 7.
-y=7-x
y=x-7
Slope is 1.
Now equation of line passing through (1,0)
0=1(1)+c
c=-1
y=x-(-1)
y=x+1
Hence y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

Step-by-step explanation:

A triangle has sides which are consecutive odd integers and an
angle of 120°. What is the perimeter of the triangle?
Answer:
Perimeter = 15
Step-by-step explanation:
We are told that the length of each of the 3 sides of the triangle are consecutive odd integers.
Thus means that we can write the 3 terms as;
(x - 2), x, (x + 2)
Thus, perimeter is;
P = (x - 2) + x + (x + 2)
P = 3x
If an angle is 120°, it means that the corresponding side that is directly opposite the angle is the largest side of the triangle.
Thus, this side is (x + 2)
Using cosine rule, we have;
(x + 2)² = x² + (x - 2)² - 2(x(x - 2))cos 120
Expanding, we have;
x² + 4x + 4 = x² + x² - 4x + 4 - (2x² + 4x)(-½)
This reduces to;
4x = x² - 4x + x² - 2x
2x² = 10x
2x = 10
x = 10/2
x = 5
Thus, other sides are;
(x - 2) = 5 - 2 = 3
And (x + 2) = 5 + 2 = 7
So,perimeter is;
P = 3x = 3 × 5 = 15

Which inequalities have no solution? Check all of the boxes that apply. 1. x > x 2. –3x –3x 3. –4 + x > –2 + x 4. x – 2 < x + 3
Answer:
1, 3
Step-by-step explanation:
1. x > x
Technically, one number cannot be more than itself. It can only equal to itself.
3. –4 + x > –2 + x
If you minus x from both sides of the equation, it becomes:
-4 > -2
This is not true no matter what x is, thus it has no solution.
4. x – 2 < x + 3
If you add 2 on both sides, it becomes:
x < x + 5
This inequality is possible and has infinitely many solutions.
Note: I will update this answer and address Question 2 once the inequality sign is given :)

5. What is the solution to the system of equations?
Answer:
4. The solution to the system of equations is: (2,-1)
5. The solution to the system of equations is: (3,5)
Step-by-step explanation:
4. What is the solution to the system of equations?
[tex]2x+3y=1\\-3x+4y=-10[/tex]
Let:
[tex]2x+3y=1--eq(1)\\-3x+4y=-10--eq(2)[/tex]
Multiply eq(1) by 3 and eq(2) by 2 and add both equations
[tex]6x+9y=3\\-6x+8y=-20\\---------\\0x+17y=-17\\y=\frac{-17}{17}\\y=-1[/tex]
So, value of y=-1
Now finding the value of x bu putting value of y in eq(1)
[tex]2x+3y=1\\2x+3(-1)=1\\2x=1+3\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, value of x=2
The solution to the system of equations is: (2,-1)
5. What is the solution to the system of equations?
[tex]y=2x-1\\6x-y=13[/tex]
Let:
[tex]-2x+y=-1--eq(1)\\6x-y=13--eq(2)\\------\\4x=12\\x=\frac{12}{4}\\x=3[/tex]
So, value of x=3
Putting value of x in equation 1 to find value of y
[tex]y=2x-1\\y=2(3)-1\\y=6-1\\y=5[/tex]
So, value of y=5

A clown sells large balloon animals for $25 each. Small balloon animals sell for $10 each. Jordan is buying 2 large balloon animals and x small balloon animals. Let y represent the total cost Jordan must pay in dollars. Part 1: Write an equation in slope-intercept form to model this description. Part 2: What is Jordan’s total cost if she purchases 4 small balloon animals? Show your work.
Answer: Part 1: y =10x+50
Part 2: Jordan’s total cost = $90
Step-by-step explanation:
Given: Price of each large balloon = $25
Price of each small balloon = $10
Price of 2 large balloons = 2 (Price of each large balloon)
= $2 (25)
= $50
Part 1: Total cost = (Number of small balloons)(Price of each small balloon) + (Number of large balloons)(Price of each large balloon)
Let x = Number if small balloons , y= total cost Jordan must pay in dollars.
Then, y= (x)(10)+(2)(25)
⇒ y =10x+50
Part 2: If she purchases 4 small balloon animals, put x=4
Then, y= 10(4)+50=40+50= 90
i.e. Jordan’s total cost = $90
Mr. Schneider paid $2276.35 to have a landscaper build a patio with the dimension below. How much did the landscaper charge for each square metre of patio? 3.2m 5.4m 1.8m 1.2m
Answer:
Step-by-step explanation:
Since we are not given the dimension. Let us say the shape of the patio is a rectangle with length 30m and width 18m.
Area of the rectangle = Length * Width
Area of the rectangle = 30 * 18
Area of the rectangle = 540m²
This means that 540m² of the patio costs $2276.35. To get the cost of each square metre of patio, we will say;
540m² = $2276.35
1m² = x
cross multiply;
540x = $2276.35
x = $2276.35/540
x = $4.22
Hence each square meter of patio will cost $4.22
Note that the dimension of patio was assumed. Same explanation can be employed for any dimension.
