What is the value of t in the equation?
-3t – 4 (t – 5) = 48
Step-by-step explanation:
-3t-4t+20=48
-7t=28
t=-4
Answer:
t = -4
Step-by-step explanation:
-3t – 4 (t – 5) = 48
Distribute
-3t -4t +20 = 48
Combine like terms
-7t +20 = 48
Subtract 20 from each side
-7t +20-20 = 48-20
-7t = 28
Divide by -7
-7t/-7 = 28/-7
t = -4

Evaluate each function. Drag the correct solution to each problem. Not all responses will be used.
Answer:
a) 1
b) 2
c) -1
Step-by-step explanation:
Choose the equation of a line parallel to the graph of 2y - 6x = 8.
a
y = - x + 1
b
y = 3x + 5
c
y = - 3x + 4
d
y = - 1/3x + 4
Answer-A
Step-by-step explanation:
Reason- in order to have two lines be parallel they must have the same slope, in this case the slope has to be 3x. If you look at A it is 2y=6x+8 and to graph it, y has to be by itself. so you divide both sides by two making it y=3x+4, and as you can see it now has a slope of 3x.

Answer: 3n+21
Step-by-step explanation: it’s the distributive property so you multiply the number outside the parentheses times the numbers or number inside the parentheses
Answer:
3n+21
IF the question required =0 then move the 21 to the other side
and divide both sides by 3 and x would equal to -7
Step-by-step explanation:
3(n+7)
use the distributive property, so multiply 3 with n and 7

An athlete eats 55 grams of protein per day while training. How much is this in milligrams?
Answer:
55,000 milligrams
Step-by-step explanation:
........
Answer:
55,000 milligrams (mg) is equal to 55 grams (g)
Step-by-step explanation:
(55 g/1 )* (1000 mg/1 g)
Multiply the top to get 55,000 and the bottom to get 1.
55,000/1
The gram units cancel out, leaving you with milligrams.
55,000 mg

Find the area for the given circle. Round to the nearest tenth.
113.0 ft^2
124.8 ft^2
37.7 ft^2
452.2 ft^2
Answer:
The answer is 113.0 ft^2
Step-by-step explanation:
To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.
The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that, the diameter of circle is 12 feet.
Here, radius = 12/2
= 6 feet
Now, area of a circle = 3.14×6²
= 3.14×36
= 113.0 square feet
Therefore, option A is the correct answer.

HELP PLEASE. What is true about the domain and range of the function?
O The domain is all real numbers less than or equal to
4, and the range is all real numbers such that -3 sXs
1.
O The domain is all real numbers such that -3 sxs1,
and the range is all real numbers less than or equal to
4.
O The domain is all real numbers, and the range is all
real numbers less than or equal to 4.
O The domain is all real numbers less than or equal to
4, and the range is all real numbers.
Answer:
Step-by-step explanation:
This equation is y=4-(x+1)^2, there is no restriction upon x and y has a max value of four and approaches negative infinity as x moves away from -1 in either direction. So the domain is all real numbers and the range is all real numbers less than or equal to four.
The domain and range of the quadratic function are:
Domain: Set of all real numbers.Range: y ≤ 4.How to get the domain and range?
For a function y = f(x), we define the domain as the set of the possible inputs x, and the range is the set of the possible values y.
On the graph, we can see a quadratic function.
For the domain, we usually start assuming that the domain is the set of all real numbers, and then we remove problematic points. Where a problematic point can be a zero on a denominator or something like that.
In the case of a quadratic, there are no problematic points, then the domain is the set of all real numbers.
For the range, we can see that the function has a maximum at y = 4, and then it goes down, so the range is just:
R: y ≤ 4.

OB. It is the graph of f(x) translated 3 units down.
OC.
It is the graph of fx) translated 3 units up.
OD. It is the graph of f(x) where the slope is decreased by 3.
Answer:
It is the graph of f(x) translated 3 units down.
Step-by-step explanation:
The graph of r(x) = x was translated 3 units down to form g(x) = r(x) - 3.
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Translation is the movement of a point either up, left, right or down.
