General rules for shifting graphs:
Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)Answer:

Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answers
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:
S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16) = 1764 m²Please help me its an easy question and please show steps (will give brainiest)

Answers
Answer:
d
Step-by-step explanation:
not a bc it has to be negative
not c bc its has to be negative
not b bc the slope is -1/2
IT'S D
Answer:
D
Step-by-step explanation:
from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.
Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.
we must then find the show of the line.
let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
so, let's label (0,3) as point 1 and (6,0) as point two. then,
x1 = 0
y1= 3
and
x2= 6
y2=0
Now we just plug in and simplify.
[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]
we now have our slope and y intercept, so we can plug them into our equation
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept.
our equation is thus
[tex]y = - \frac{1}{2} x + 3[/tex]
so, the answer is D

Answer:
The point (Negative 4, negative one-fourth) is a solution to this system of equations
Step-by-step explanation:
y = 8x - 2
y = - 4x - 5
y - 8x = - 2 - - (1)
y + 4x = - 5 - - - (2)
Subtract 1 and 2
-8x - 4x = - 2 - (-5)
-8x - 4x = 3
-12x = 3
x = - 1/4
y = 8(-1/4) - 2
y = - 2 - 2
y = - 4
(-1/4, - 4)

Answer:
x=6
Step-by-step explanation:
x+54+5x=90
6x+54=90
6x=36
x=6
Answer:
x=6
Step-by-step explanation:
So, lets go over what we know.
Angle 5x and angle x+54 make up 90 degrees.
We know its 90 degrees since there is a square like symbol on the side of the line.
To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.
So:
5x+x+54=90
=
6x+54
Now that we combined our two angles, we can solve it like a normal equation:
6x+54=90
subtract 54 from both sides to get 6x alone:
6x=36
Now divide both sides by 6 so x is alone:
x=6
So now we know that x=6.
If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:
Angle 5x:
5*6
=
30
Angle x+54
6+54
=
60
Add the two angles together:
30+60
=
90
So we have checked and the answer is still correct!
Hope this helps! :D

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answers
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

Greg uses a triangular area of his back yard as a garden.If the area if his garden 1.248 square feet,whats the area of the garden?
Answers
Answer:
192 ft²
Step-by-step explanation:
Area of rectangular backyard = 1248 ft²
Width of backyard = 52 ft
Length = x
Area of rectangular backyard = Length * width
1248 = x * 52
x = 1248 / 52
x = 24 feets
Hence, x = height of triangular garden
Area of triangle = 1/2 base * height
Area = 1/2 * 16 * 24
Area = 192 ft²

Answer:
The answers are A, B and C.
Step-by-step explanation:
To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57
Next Divide 21 on both sides. -57/21 is -36
You should have -3k > -57
Divide -3 on both sides. -57/-3 is 12
You should end up with k > 12
And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.
