Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or neither.
Answers
Answer:
Step-by-step explanation:
to know:
-to be paralel the lines have to have the same slope
-to be perpendicular the slope has to be negative invers of thhe other
-to be neither has to be none of the above two
equation to compare to is
y=mx+b where m is the slope
if your equation does not have this form make it have this form
2y=3x+1 so divide by 2
y=[tex]\frac{3}{2}[/tex] x+1 so here the slope is [tex]\frac{3}{2}[/tex]
4x+6y=14 so subtract 4x and then divide by 6 to isolate y
6y= -4x+14
y=[tex]\frac{-4}{6}[/tex] x + [tex]\frac{14}{6}[/tex] symplify
y=[tex]\frac{-2}{3}[/tex] x + [tex]\frac{7}{3}[/tex] so the slope here is [tex]\frac{-2}{3}[/tex]
So if you compare the slopes you can see that are negative reciprocal of eachother so the lines are perpendicular
and so on...

Answer:

divide both sides of the first equation by 2 to get y by itself. this gets you y=x/2-2
then plug that into the other equation:
4x+3(x/2-2)=5
SImplify that to get:
4x+3x/2-6=5
Add 6 to both sides:
4x+3x/2=11
give 4x a denominator of 2 as well:
8x/2+3x/2=11
add them:
11x/2=11
multiply both sides by 2/11 to get:
x=22/11 which simplifies to x=2
plug x into first equation:
2y=(2)-4
simplify:
2y=-2
divide both sides by 2 to get:
y=-2/2 which is the same as -1
x=2
y=-1
answer: (2,-1)

which equation is perpendicular to the graph of 5x - 3y = 12
Answers
Answer:
y = -3/5x + c
Step-by-step explanation:
Re-arrange the initial equation so that the it becomes y =
To do this, you +3y on both sides to get 5x = 3y + 12
And then -12 on both sides to get 5x - 12 = 3y
Divide everything by 3 so you get 5/3x - 4 = y OR y = 5/3x - 4
The gradient of the initial equation is 5/3, to find the perpendicular line, you need the negative reciprocal of it, which is -3/5
Therefore your perpendicular line should be y = -3/5x + c
Because you didn't specify on what point they intersect, i can't find c for you.

In New Salem North Dakota there is a 38-ft-tall statue of a cow named Salem Sue. Suppose the statue's shadow was 57 feet long and a 3.5 foot child was standing next to the statue. How long would the child statue be?
Answers
Answer:
5.25 feets
Step-by-step explanation:
Given that:
Height of Salem Sue = 38 feets
Height of Salem Sue's shadow = 57 feets long
Height of child standing next to the statue = 3.5 foot tall
Length of the child's shadow =?
Let lenght of child's shadow = s
IF;
38 Feets tall = 57 feets lenght
3.5 feets tall = s feets long
Cross multiply :
38 * s = 57 * 3.5
38s = 199.5
38s / 38 = 199.5 /38
s = 5.25
Hence, length of the child's shadow will be 5.25 feets long

h(g(f(x))) = h(g(2x+5)) = h((2x+5)²) = h(4x²+20x+25) = -2(4x²+20x+25)

A. 2x-4
Step-by-step explanation:
2x-4 since when you factor this expression, you get (2x-4)^2. a square has equal sides and is calculated by side length squared, so simply take the square root of the known area (2x-4)^2 and you get 2x-4.

The figure is made from squares of different sizes.Find the area of A if the side of each of the two indentical smallest square is 2cm.
Answers
Answer:
The area of square A is 256 cm²
Step-by-step explanation:
The four sides of a square are equal in lengthArea of a square = side × sideIn the given figure
∵ The sides of the square E = 2 cm each
∵ The sides of the square F = 2 cm each
∵ The side of square D is the sum of the sides of squares E and F
∴ The sides of the square D = 2 + 2 = 4 cm each
∵ The side of square C is the sum of the sides of squares E and D
∴ The sides of square C = 2 + 4 = 6 cm each
∵ The side of square B is the sum of the sides of squares C, E, and F
∴ The sides of square B = 6 + 2 + 2= 10 cm each
∵ The side of square A is the sum of the sides of squares B, F, and D
∴ The sides of square A = 10 + 2 + 4= 16 cm each
∵ Area of square A = side × side
∴ Area of square A = 16 × 16
∴ Area of square A = 256 cm²
∴ The area of square A is 256 cm²

gross pay $23760 married with 3 dependents state income tax rate 4%
Answers
Answer:
950.40
Step-by-step explanation:
The annual amount withheld for state tax would be $950.40.
Given that, gross pay $23760 married with 3 dependents state income tax rate 4%,
We need to calculate, amount withheld annually for state tax.
To calculate the annual amount withheld for state tax, we need to multiply the gross pay by the state income tax rate.
Here's the calculation:
Annual state tax withheld = Gross pay x State income tax rate
Gross pay = $23,760
State income tax rate = 4% (0.04)
Annual state tax withheld = $23,760 x 0.04 = $950.40
Therefore, the annual amount withheld for state tax would be $950.40.
