Answer:
[tex]y=-x[/tex]
Step-by-step explanation:
The slope-intercept form of a line can be written as [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope, [tex]b[/tex] is the y-intercept, and [tex](x,y)[/tex] are the coordinates of any point that this line passes through.
Perpendicular lines have negative-reciprocal slopes. Therefore a line perpendicular to [tex]y=x+2[/tex] will have a slope of [tex]-\frac{1}{1}=-1[/tex].
Now that we have a slope and coordinates of a point that the line passes through, we can solve for the y-intercept and the equation of the line:
[tex]-2=-1(2)+b, \\b=0[/tex]
Thus, the equation of this line is [tex]\fbox{$y=-x$}[/tex].
Hard Equation that equals 1-25

Which one of these transformations would produce an image that is not congruent to its pre-image? (4 points)
A translation of (x − 1, y − 3)
A rotation of 90 degrees about the origin
A rotation followed by a translation
A dilation followed by a reflection
Answer:
A dialation followed by a reflection
Step-by-step explanation:
When you dialate a shape it changes the size which makes the shape similar but not congrouent.
The option “a dilation followed by a reflection” will produce an image that is not congruent to its pre-image option, fourth is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
As we know, the translation will shift the object.
If rotate the image with 90 degree about origin will change the orientation of the image but shape will remains same.
A dilation followed by reflection will change the image because the transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller.
Thus, the option "a dilation followed by a reflection" will produce an image that is not congruent to its pre-image option fourth is correct.

Answer:
Slope/m=1/2, y-intercept=-4
Step-by-step explanation:
Y=mx+b is slope-intercept form. So in the equation y=1/2x-4, m stands for the slope, and in the equation 1/2 is in the place of m. B stands for the y-intercept, and in its place is -4.

What is the area of the figure to the nearest hundredth? Enter the answer in the box.
square meters
Answer:
Step-by-step explanation:
we have a rectangle and a semicircle,
area rectangle=14*4=56
area of semicircle
diameter is 4, than r=2
A of the circle=3.14*r^2=3.14*4=12.56
we have a semicircle so we will divide the area by 2
A=12.56/2=6.28
total area=56+6.28=62.28
At T-Shirts R Us, the cost to make new shirts is $1.50 per shirt plus a $50 set-up fee. At T-Shirt Planet, the set-up fee is $75 and $1 per shirt. Find the number of shirts you can order so that the cost at both companies is the same.
Answer: The number of shirts you can order = 40
Step-by-step explanation:
Let x = Number of shirts
At T-Shirts R Us,
Total cost = 50+1.50x
At T-Shirt Planet,
Total cost = 75+x
As per given, when the cost at both companies is the same then
[tex]1.50x+50=x+70\\\\\Rightarrow\ 1.50x-x=70-50\\\\\Rightarrow 0.50x=20\\\\\Rightarrow\ x=\dfrac{20}{0.50}=40[/tex]
Hence, the number of shirts you can order = 40

What percent of 18 is 24?
Answer:
133.33%
Step-by-step explanation:
you can find this by doing 24/18x100, which is equal to 133.33
Answer:
133%
Step-by-step explanation:
We're going to divide [tex]\frac{24}{18}[/tex].
That equals about 1.33 repeating.
Next, we're multiplying that decimal by 100.
That gets us 133.

Jake said he can find 630 ÷ 10 by taking the 0 off of 630 to get 63. Jake finds 35.270 ÷ 10 using the same method and gets 35.27. Use the drop-down menus to complete the statement about why Jake is correct or incorrect.
Answer:
Jake is incorrect with his methodology for solving these problems
Step-by-step explanation:
Jake is incorrect with his methodology for solving these problems. This is because dividing a number by 10 requires moving the decimal point one digit to the left. When dividing 630 by 10, removing the zero works because by moving the decimal one digit to the left we would simply drop the zero and the decimal would not be needed leaving the answer as 63. However, this does not work on numbers that already have a decimal such as 35.270. This number divided by 10 would be 3.527 but simply removing the 0 like Jake states would give us the incorrect answer of 35.27

Find the simple interest for 3 years at a rate of 5% on $200
Answer:
The simple interest is $30
Step-by-step explanation:
To find this, we use the simple interest formula
Mathematically, this is;
I = PRT/100
P is the principal = $200
R is the rate = 5%
T is the time = 3 years
Substituting these values, we have;
I = (200 * 5 * 3)/100
I = $30

The regular price of a skateboard is p. Which expression represents the price of the skateboard when it is on sale for 25% off? Select all that apply.
Answer: The expression represents the price of the skateboard when it is on sale for 25% off = 0.75p
Step-by-step explanation:
Given: Regular price of a skateboard is p.
Discount = 25% off = 0.25p
Now, the price of the skateboard when it is on sale for 25% off = p - Discount
= p -0.25p
= (1-0.25)p
= 0.75p
Hence, the expression represents the price of the skateboard when it is on sale for 25% off = 0.75p
Answer: The expression represents the price of the skateboard when it is on sale for 25% off = 0.75p
Step-by-step explanation:
On a certain hot summer's day, 263 people used the public swimming pool. The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $437.50. How many children and how many adults swam at the public pool that day?
Answer:
The number of children = x = 176
The number of Adults = y = 87
Step-by-step explanation:
Let us represent
The number of children = x
The number of Adults = y
On a certain hot summer's day, 263 people used the public swimming pool.
x + y = 263.... Equation 1
x = 263 - y
The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $437.50.
$1.25 × x + $2.50 × y = $437.50
1.25x + 2.50y = 437.50.....Equation 2
We substitute 263 - y for x in Equation 2
1.25(263 - y) + 2.50y = 437.50
328.75 - 1.25y + 2.50y = 437.50
- 1.25y + 2.50y = 437.50 - 328.75
1.25y = 108.75
y = 108.75 ÷ 1.25
y = 87
Solving for x
x = 263 - y
x = 263 - 87
x = 176
Therefore:
The number of children = x = 176
The number of Adults = y = 87
