On a coordinate plane, a square has points A (negative 5, 2), B (1, 2), C (negative 4, 1), and D (negative 5, negative 4). If a translation of is applied to square ABCD, what is the y-coordinate of B'?
Answer:
The y coordinates of B' is: 8
Step-by-step explanation:
Given
[tex]A = (-5,2)[/tex]
[tex]B =(1,2)[/tex]
[tex]C = (-4,1)[/tex]
[tex]D = (-5,-4)[/tex]
Translation of (x, y) → (x + 6, y – 10) ---Missing from the question
Required
Determine the y coordinates of B'
We have:
(x, y) → (x + 6, y – 10)
And
[tex]B =(1,2)[/tex]
So the translation from B to B' is:
[tex]B (1,2) \to B'(1+6,2-10)[/tex]
[tex]B (1,2) \to B'(7,-8)[/tex]
So, we have:
[tex]B' = (7,-8)[/tex]
The y coordinates of B' is: 8
Answer:
-2

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.
Answer:
So the next time they will leave together is 4:24 pm
Step-by-step explanation:
Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.
The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.
Factors of 6 = 2*3
Factors of 8= 2*2*2
In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M
L.C.M= 2*2*2*3= 24 minutes
So the next time they will leave together is 4:24 pm
Mhanifa can you please help? Look at the picture attached. I will mark brainliest!
Answer:
a) Opposite sides are congruent and all interior angles are right angles, hence the quadrilateral is a rectangle
yesb) Opposite sides are parallel and all sides are congruent, hence the quadrilateral is a rhombus
yesc) All sides are congruent and all interior angles are right angles, hence the quadrilateral is a square
yesd) m∠AEB = 90° as the diagonals are perpendicular to each other
90°e) m∠EAD = 90°/2 = 45° as the diagonals of a square are bisectors of the angles at the vertices
45°The temperature drops to a rate of five degrees per hour. Be d the number of degrees that lowers the temperature. Be the number of hours you spend. What is the dependent variable?
Answer:
d, the number of degrees that the temperature was lowered by
Step-by-step explanation:
The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.
pls help with these math problems
Answer:
Step-by-step explanation:
1)
First we add what we know for y into the second equation.
5x - 4(x +2)= -3
From there, we simplify it
5x-4x-8= -3
x-8=-3
Now we get the x on its own
x=5
and now we add x=5 into the first equation that we had and simplify to find y
y=5+2
y=7
So the answer is x=5, y=7 or (5,7)
2)
For this one we do the same thing as with 1.
Add what we know for y (bottom equation) to the top equation
3x-8(x-8)=24
Now we simplify
3x-8x+64=24
-5x+64=24
And now solve for X
-5x=-40
x=8
And then substitute x=8 to find y
y=8=8
y=0
So the answer is x=8, y=0 or (8,0)

The formula for finding the volume of a cone is V=
nur?n. The radius of a cone is 5 cm and the height of a cone is 10
cm. What is the approximate volume of the cone?
Answer:
261.8 cm^3
Step-by-step explanation:
1) find the base area
base area = radius^2 x pi = 5^2 x pi = 25 x pi = 78,539816 cm^2
2) find the volume
V = (base area x height)/3 = (78.539816 x 10)/3 = 785.3/3 = 261.8 cm^3

Answer:
Negative
Step-by-step explanation:
On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.
Example:
-1 + .5 = -.5
-2 + .5 = -1.5
-3 + .5 = -2.5
Answer: Negative
Step-by-step explanation: the b we can see is far away from -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5

Answer:
d) [tex](9*3/4)+y[/tex]
Step-by-step explanation:
b) [tex]9+y*(3/4)[/tex]
This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.
c) [tex](y+9)(3/4)[/tex]
This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].
[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]
d) [tex](9*3/4)+y[/tex]
This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:
[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]
I hope this helps!

7x + 2y - 3 = 0 in slope intercept form.
Answer:
y=(-7/2)x+3
Step-by-step explanation:
7x+2y-3=0
7x+2y=3
2y=-7x+3
y=(-7/2)x+3
Answer:
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y - 3 = 0 ( subtract 7x - 3 from both sides )
2y = - 7x + 3 ( divide each term by 2 )
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

Find the value of x: 3x−7=8x+23
Answer: x=6
Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
Subtract 3x from both sides to get -7=5x+23.
Subtract 23 from both sides to get -30=5x.
Divide 5 from both sides.
x = -6.
