Answer:
y=x+7
Step-by-step explanation:
y-7=1(x-0)
y-7=x-0
y=x+7
Answer:
y=x+7
Step-by-step explanation:
You need a slope that is opposite the slope of equation y=-x-5. To do this you need to find the opposite reciprocal. For -1, the opposite reciprocal would be 1. So, your slope is going to be 1.
You need the line to pass through (0,7), which is a point on the y axis. b in y=mx+b is the y-intercept. So, you would make 7 your b.
By plugging in these numbers you end up with y = x + 7

Susan designed a circular pool with a diameter of 25 meters. what is the area of the bottom of the pool? round to rhe nearest tenth.
Answer:
Area is 491.07m to the nearest tenth
Step-by-step explanation:
Solve the quadratic equation: 3x2 + x - 5 = 0
Hey there!
[tex]3x^2 + x -5 = 0[/tex]
This equation is in standard form, which is [tex]ax^2+bx+c=0[/tex].
We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.
a = 3, b = 1, c = -5
Let's plug these values into the quadratic equation:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
[tex]x=\frac{-1\pm\sqrt{1^2-4(3)(-5)} }{2(3)}[/tex]
Multiply 4(3)(-5) together and multiply 2(3). Square 1.
[tex]x=\frac{-1\pm\sqrt{1+60} }{6}[/tex]
Add 1 and 60.
[tex]x=\frac{-1\pm\sqrt{61} }{6}[/tex]
This is our answer in exact form. If you need this as an approximate value, let me know and I will do that for you.

Leah and Christopher work at a dry cleaners ironing shirts. Leah can iron 25 shirts per hour, and Christopher can iron 15 shirts per hour. Leah and Christopher worked a combined 13 hours and ironed 265 shirts. Write a system of equations that could be used to determine the number of hours Leah worked and the number of hours Christopher worked. Define the variables that you use to write the system.
25x + 15y = 265
x+y = 13
Step-by-step explanation:
Step 1:
Given
Number of shirts Leah can iron in an hour = 25 shirts
Number of shirts Christopher can iron in an hour = 15 shirts
Total number of hours worked by both = 13 hours
Total number of shirts ironed by them = 265 shirts
Step 2 :
Let x represent the number of hours Leah works and y represent the number of hours Christopher works
Leah irons 25 shirts in one hour, so in x hours he would iron 25x shirts
Christopher irons 15 shirts in one hour, so in y hours he would iron 15y shirts
Given total shirts ironed by them together is 265 , we have
25x + 15y = 265
They worked a combined of 13 hours, so
x+y = 13
Step 3:
The system of equations that could be used to determine the number of hours Leah worked and the number of hours Christopher worked are ,
25x + 15y = 265
x+y = 13
Answer:
System of Equations:
x + y = 13
25x + 15y = 265
x = number of hours Leah works
y = the number of hours Christopher works

Solve for b.
7b = 35
Answer:
b = 5
Step-by-step explanation:
to get b, you see that is multiplied by 7. to get rid of the 7, you have to divide both sides by 7. this is because 7/7 = 1, so you would just have b. then, 35/7 equals 5, and it is on the other side of the equal sign, so you would have b = 5.
Answer:
[tex]b = 5[/tex]
Step-by-step explanation:
[tex]7b = 35 \\ \frac{7b}{7} = \frac{35}{7} \\ b = 5[/tex]

Two angles are vertical angles. One angle
measure is 68. What is the measure of
the other angle?
A. 22°
B. 68°
C. 90°
D. 112
In the context of geometry, vertical angles are always congruent, which means they have the same measure. If one of the vertical angles measures 68°, the measure of the other angle is also 68°. Therefore, the correct answer is B. 68°.
Explanation:The question is asking for the measure of the second angle, given that two angles are vertical angles and one of them measures 68°. In terms of geometry, vertical angles are the angles that are opposite each other when two lines intersect. An important property of vertical angles is that they are always congruent, which means they have the same measure. So, if one of the vertical angles is 68°, the other angle is also 68°. Hence, the correct answer is B. 68°.

#SPJ12
Since vertical angles are always congruent, the measure of the other angle is also 68°.
The question involves identifying the measure of the other angle when two angles are vertical angles. Vertical angles are angles that are opposite each other when two lines intersect. They are always equal to each other in measure.
Given that one angle measures 68°, the other angle, being a vertical angle, will also measure 68°.
Therefore, the correct answer is: B. 68°

A square has a perimeter of 32 inches what the length and width of the square
The length and width of square is 8 inches.
Step-by-step explanation:
Given,
Perimeter of square = 32 inches
We know that all sides of square are equal, therefore,
Length = width = s
Perimeter of square = 4s
[tex]32=4s\\4s=32[/tex]
Dividing both sides by 4
[tex]\frac{4s}{4}=\frac{32}{4}\\s=8[/tex]
Therefore,
The length and width of square is 8 inches.
Final answer:
The length and width of the square are each 8 inches, calculated by dividing the given perimeter of 32 inches by the number of sides of a square, which is 4.
Explanation:
To find the length and width of a square given its perimeter, we need to recall that all four sides of a square are of equal length. Since the perimeter of the square is 32 inches, we divide this number by 4 to find the length of one side. So, the length and width of the square are:
32 inches ÷ 4 = 8 inches.
Therefore, each side of the square is 8 inches long.

Answer:
Both [tex]x<-36\quad \mathrm{or}\quad \:x>72[/tex] are the True solutions.
Step-by-step explanation:
Considering the expression
[tex]\left|6-\frac{x}{3}\right|>18[/tex]
[tex]\mathrm{Apply\:absolute\:rule}:\quad \mathrm{If}\:|u|\:>\:a,\:a>0\:\mathrm{then}\:u\:<\:-a\:\quad \mathrm{or}\quad \:u\:>\:a[/tex]
[tex]6-\frac{x}{3}<-18\quad \mathrm{or}\quad \:6-\frac{x}{3}>18[/tex]
solving
[tex]6-\frac{x}{3}<-18[/tex]
[tex]6-\frac{x}{3}-6<-18-6[/tex]
[tex]-\frac{x}{3}<-24[/tex]
[tex]3\left(-\frac{x}{3}\right)<3\left(-24\right)[/tex]

[tex]\left(-x\right)\left(-1\right)>\left(-72\right)\left(-1\right)[/tex]
[tex]x>72[/tex]
also solving
[tex]6-\frac{x}{3}>18[/tex]
[tex]6-\frac{x}{3}-6>18-6[/tex]
[tex]-\frac{x}{3}>12[/tex]
[tex]-x>36[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]
[tex]\left(-x\right)\left(-1\right)<36\left(-1\right)[/tex]
[tex]x<-36[/tex]
[tex]\mathrm{Combine\:the\:intervals}[/tex]
[tex]x<-36\quad \mathrm{or}\quad \:x>72[/tex]
Verifying the solution:
Putting the value x < -36 in [tex]\left|6-\frac{x}{3}\right|>18[/tex]
let suppose x = -37 which is < -36
[tex]\left|6-\frac{x}{3}\right|>18[/tex]
[tex]\left|6-\frac{\left(-37\right)}{3}\right|>18[/tex]
[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]
[tex]=\left|6+\frac{37}{3}\right|[/tex]
[tex]=\left|\frac{55}{3}\right|[/tex]
[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]
[tex]\frac{55}{3}>18[/tex]
[tex]\mathrm{Therefore,\:the\:solution\:is}[/tex]
[tex]\mathrm{True}[/tex]
also putting the value x > 72
let suppose x = 73 which is > 72
[tex]|6-\frac{\left(73\right)}{3}|>\:18[/tex]
[tex]=\left|-\frac{55}{3}\right|[/tex]
[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|-a\right|=a[/tex]

On average, Ainsley and her friends could complete 44 sit-ups in one minute. The number of sit-ups done by each of her friends is listed below. How many did Ainsley complete? *
47, 46, 38, 45, 41
Answer:
47
Step-by-step explanation:
The numbers given as 47, 46, 38, 45, 41 represent 5 people and adding Ainsley, they are 6 people.
The sum of individual sit ups by the 5 will be
47+46+38+45+41=217
Since the mean for 6 people is 44, it means their sum is 6*44=264
Getting the difference between the sum for 6 people and the sum for five people we get that
264-217=47
This is the number of sit-ups for the sixth person who is Ansley

Final answer:
The expression x²−12x+36 is factored as (x-6)(x-6) or (x-6)².
Explanation:
The expression x²−12x+36 represents a quadratic equation. To factor this expression, we look for two numbers that both add to the middle term, -12, and multiply to the constant term, 36. The numbers that fit this requirement are -6 and -6, since (-6) + (-6) = -12 and (-6) × (-6) = 36. Therefore, the expression in factored form is (x-6)(x-6), which can also be written as (x-6)².
