What is the value of X?
Answer:
61 degrees
Step-by-step explanation:
180 - 58 = 122
Since both sides are congruent, 122/2 = 61
Answer:
61
Step-by-step explanation:
Since ED and EF are congruent, Angle D = Angle F meaning angle F is also x degrees.
From here, we can use the total sum of angles in a triangle = 180 to calculate x:
180 = 58 + x + x
180 = 58 +2x
122 = 2x
x= 61 degrees

Determine which equation represents a function.
A. y = -2x + 1
B. x=4
C. x=y²-1
D. y²-x
The equation that represents a function is (A) y = -2x + 1.
A Function is defined as an equation for which any "x" we substitute in the equation will give only one output such as "y"
it is denoted by y=f(x).
In the given question
Option (A)
y=-2x+1
Yes the given equation is a function ,
because when we substitute a value in x ( let x=2) it gives only a single output (y=-3).
Hence , y=-2x+1 is a function .
Option (B)
x=4
No, it is not a function as ,
x=4 is a vertical line parallel to y axis ,
we know that for a function every value of x will have exactly one y .
For x=4 , y can 0 , -9 , 6 .
Hence , x=4 is not a function.
Option (C)
x=y²-1
No. it is not a function ,
we know that for a function every value of x will have exactly one y .
For x=0 , y=+1,-1 .
Hence , x=y²-1 is not a function .
Option (D)
y²-x
No , it is not a function
As y²-x do not have an equal to sign "=" , it cannot be considered as an equation.
Hence , y²-x is not a function .
Therefore , Only y = -2x + 1 represents a function , the correct option is (A) y = -2x + 1

Quadrilaterals ABCD and EFGH are shown in the coordinate plane. Quadrilaterat ABCD will be reflected across the x-axis and then rotated 90 clockwise about the origin to create quadrilateral A^ prime B^ prime C^ prime D^ prime . What will be the y -coordinate of B?
Answer:
Step-by-step explanation:
180 degree rotation about point C prime composition reflected across line m
Transformation involves changing the position of a quadrilateral by reflecting and/or rotating it.
The y-coordinate of B" is 3
The coordinates of vertex B of quadrilateral ABCD is:
[tex]\mathbf{B = (-3,7)}[/tex]
The rule of reflection across the x-axis is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{B' = (-3,-7)}[/tex]
The rule of 90 degrees clockwise rotation across the origin is:
[tex]\mathbf{(x,y) \to (y,-x)}[/tex]
So, we have:
[tex]\mathbf{B" = (-7,3)}[/tex]
Hence, the y-coordinate of B" is 3

Answer: 7 and 8
Step-by-step explanation:
Square root and squared cancel out
Answer:
a=7
b=32
Step-by-step explanation:
The first one (a) is 7 because if you square a square root, you get the number inside the root. Also, technically a square root has an exponent of (1/2) so when you have a power-to-a-power (power rule of exponents) you multiply the exponents. So ([tex]7^{1/2}[/tex])^2 is 7.
For (b) you have to take it in two parts. Square the square root and you get 2. Square the 4 in front, you get 16. Multiply those two numbers (16 and 2) together and you get 32.

Complete Question
For there are 48 apples and 60 bananas and 96 oranges each basket must contain the same number of each type of fruit. Find the greatest number of baskets you can have
Answer:
The greatest number of baskets you can have is 12 baskets.
And each baskets would contain:
4 apples, 5 bananas and 8 oranges
Step-by-step explanation:
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Then the greatest common factor is 12.
Therefore, the greatest number of baskets you can have is 12 baskets.
Each baskets would have
For apples
48 apples
48 apples / 12 baskets = 4 apples per basket
For bananas
60 bananas
60 bananas/12 baskets = 5 bananas per basket
For Oranges
96 Oranges/ 12 baskets = 8 oranges per baskets

find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s.
The central angle in radians is given by θ = s/r, where s is the arc length and r is the radius of the circle
For given question,
we need to find the radian measure of the central angle of a circle of radius r.
The central angle intercepts an arc of length s.
Let θ be the central angle in radians.
We know that the arc length of circle of radius r is,
s = r × θ
where s is the arc length
r is the radius of the circle
θ is the central angle measured in radians
From above equation,
we have, θ = s ÷ r
Therefore, the central angle in radians is given by θ = s/r, where s is the arc length and r is the radius of the circle

Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°

Atticus is examining the equations: 4x + 2y = 10 and y = -2x + 5. He states that the equations are equivalent. Is he correct why or why not?
Answer:
He is correct
Step-by-step explanation:
Put the first equation into y = mx + b by isolating y:
4x + 2y = 10
2y = -4x + 10
Divide each side by 2:
y = -2x + 5
So, putting the first equation into y = mx + b got us the same equation as the second one, y = -2x + 5.
Since they are the same, the equations are equivalent.
Atticus is correct.
slope intercept form
through: (2, 4) and (1, -3)
Answer: I attached a graph below, hope it helps.
Step-by-step explanation:
A line can be written in the form y = mx + b where m is the slope and b is the y intercept.
Since the slope is given as 4, the equation will be y = 4x + b
Plugging in the point (2,1) to the equation we get 1 = 4(2) + b or 1 = b + 8
Solving for b gives b = -7 so the equation will be y = 4x - 7
