How do I solve this and what is the answer?

Answer:

20°

Step-by-step explanation:

Rotation is one of 3 basic rigid transformation, it will not change the original shape and size. Therefore angle B' should be still 20°

The degree measurement of angle B′ will be same as angle B that is 20°. Then the correct option is A.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.

From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.

Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.

If the geometry is rotated, then there is no change in anlges.

Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°.

The degree measurement of angle B′ will be same as angle B that is 20°.

Then the correct option is A.

Answer:

[tex]-x^2+63x-130[/tex]

Step-by-step explanation:

When you put that into an equation:

[tex]x(88-x)-(130+25x)[/tex]

Next, solve.

[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:-\left(a+b\right)=-a-b[/tex]

[tex]-\left(130+25x\right)=-130-25x[/tex]

[tex]=x\left(88-x\right)-130-25x[/tex]

[tex]x(88-x):88x-x^2[/tex]

[tex]=88x-x^2-130-25x[/tex]

[tex]88x-x^2-130-25x =-x^2+63x-130[/tex]

Therefore, the profit if the cost of producing [tex]x[/tex] units is [tex]-x^2+63x-130[/tex], and there may be restrictions depending on conditions.

3 is the slope. Rise 3 run 1 or up 3 right 1.

4 is the y-intercept

If 6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange, one lime costs the same as half of one banana.

Let's assume the cost of one banana is represented by "B" and the cost of one orange is represented by "O". Based on the given information:

6 bananas cost the same as 4 oranges: 6B = 4O

3 lemons cost the same as 1 orange: 3L = 1O

2 limes cost the same as 1 lemon: 2L = 1O

Now, we need to find the cost of one lime in terms of bananas:

From equation 3, we can rewrite it as: L = (1/2)O

Substitute the value of O from equation 2 into the above equation: L = (1/2) * 3L

Now, we have the cost of one lime in terms of lemons. From equation 2, we know 3 lemons cost the same as 1 orange, so we can rewrite it as: L = (1/2) * (1/3)O

Now, substitute the value of O from equation 1 into the above equation: L = (1/2) * (1/3) * 6B

L = (1/2)B

Therefore, one lime costs the same as half of one banana.

Step-by-step explanation:

remember that empty dots mean "exclusive", and dark, filled dots mean "inclusive".

then, regular line functions look like

y = ax + b

with a being the slope (ratio of y/x indicating how much y changes, when x changes), b being the y-intercept (y-value when x = 0).

the left part is simply a line parallel to the x-axis. the slope is 0, as the line is not climbing or declining.

so, it is simply

y = 4

the right part is a line going from (0, 5) to (6, 8).

x changes by +6 (from 0 to 6), y changes by +3 (from 5 to 8). so, the slope is 3/6 = 1/2

and with the starting point at the y-axis we have also the y-intercept.

so, the line equation there is

y = (1/2)x + 5

now together with the proper intervals of validity :

y = 4, -6 < x < 0

y = (1/2)x + 5, 0 < x <= 6

Answer:

x= -4

Step-by-step explanation:

3x-5=7x+11

3x-5+5=7x+11+5

3x=7x+11+5

3x=7x+16

3x-7x=7x+16-7x

-4=7x+16-7x

-4x=16

divided each side by -4

x= 16 over -4

divide them and you get -4.

Step-by-step explanation:

find equations

henry:

y-int is 15 because that is the starting number. the slope is 3 because that is how much his points are increasing for every successful shot. we can use this information to form this equation:

y = 3x + 15

brother:

y-int is 20 because that is the starting number. slope is 3 because that is how many points he gets for each successful shot. using this information, we can form the following equation:

y = 2x + 20

solve

y = 3x + 15

y = 2x + 20
