A team is playing a game and currently has 43 points. If they lose 56 points and then gain 13 points, what will their score be? Write an expression that models this situation and evaluate the expression.
Answer:
(43 - 56) + 13 = 0 points
Step-by-step explanation:
We start with 43 points and loose 56 -- 43-56
then, 13 points are gained = (43 - 56) + 13
simplify and solve:
-13 + 13 = 0
*Note: you can write the expression without the brackets

two years ago randi earned $18,400. last year she earned $19,700. suppose she earns $21,600 this year. how much would randi have to earn next year so that her four year average is $21,000
Randi earn $24,300 next year.
Here,
Given that;
Two years ago Randi earned $18,400. last year she earned $19,700.
And, she earns $21,600 this year.
The average of four year is $21,000
We have to find, the amount she earn in next year.
What is Average?
A number that is calculated by adding quantities together and dividing the total by the number of quantities.
Now,
Let she earn $ x in next year.
The average of four year is $21,000.
Hence, Average of money for four year is;
[tex]\frac{18,400+19,700+21,600+x}{4} = 21,000[/tex]
[tex]59,700 + x = 84,000[/tex]
[tex]x = 24,300[/tex]
So, She earn $24,300 in next year.

Help!!! What is the equation of the following function? Show any work.
Answer:
[tex]y=-3(x+2)^2-3[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The graph provided in the question, assumed as a parabola, has two clear points:
The vertex, located at (-2,-3)
The point (-1,-6)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-(-2))^2-3[/tex]
[tex]y=a(x+2)^2-3[/tex]
The value of a will be determined by using the other point (-1,-6):
[tex]-6=a(-1+2)^2-3[/tex]
Operating:
[tex]-6=a(1)-3[/tex]
Solving:
a=-3
The equation of the graph is:
[tex]\boxed{y=-3(x+2)^2-3}[/tex]

12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)
Step-by-step explanation:
Length = x
Width = (x-5)
Perimeter = 2 lengths + 2 widths
50 ft = x + x + (x-5) + (x-5)
50 ft = 4x - 10
60 ft = 4x
15 ft = x
length = x = 15 ft
width = (x-5) = (15 -5) = 10 ft
dimensions = length × width
= 15 ft × 10 ft
if you wanna check,
50 ft = x + x + (x-5) + (x-5)
50 ft = 15 + 15 + (15-5) + (15-5)
50 ft = 30 +(10+10)
50 ft = 30 + 20
50 ft = 50

Please help quickly
Let's see what to do buddy...
_________________________________ Step (1)
First we must find the measure of x
[tex](3x - 5) + (x + 1) = 180[/tex]
[tex]4x - 4 = 180[/tex]
Both sides plus 4
[tex]4x = 184[/tex]
Divided both sides by 4
[tex]x = \frac{184}{4} \\ [/tex]
[tex]x = 46[/tex]
_________________________________
Step (2)
Now we must find the RQS Angle measure :
Angle ( RQS ) = 46 + 1 = 47
_________________________________
Step (3)
QT bisects RQS ;
So the resulting angles are :
[tex] \frac{47}{2} = 23.5 \\ [/tex]

And we're done.

Explain how to find the sum −8.46+5.31. a.) Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative. b.) Because |5.31|>|−8.46|, subtract |−8.46| from |5.31| and the sign is negative. c.) Because |−8.46|>|5.31|, add |−8.46| and |5.31| and the sign is negative. d.) Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is positive. HELP!! I am doing my hw for math and I don't get this question!!
Step-by-step explanation:
Sum of −8.46 and 5.31 means we need to add −8.46+5.31.
We know that,
|-8.46| > |5.31|
It means we subtract 8.46 - 5.31
At hundredth place, 6-1 = 5
At tenths place, 4-3 = 1
At ones place, 8-5 = 3
It would mean that, 8.46 - 5.31 = 3.15
8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15
Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".
