At a basketball game, a team made 51 successful shots. They were a combination of 1- and
2-point shots. The team scored 83 points in all. Write and solve a system of equations to find the
number of each type of shot.
There were 2-point shots and 1-point shots.
Answer:
19 1-point shots and 32 2-point shots
Step-by-step explanation:
Let x be the amount of 1-point shots they made and y be the amount of 2-point shots they made then...
x+y=51
x+2y=83
We can solve this equation using elimination. In this case, we can eliminate x be subtracting the two equations.
-y=-32
Divide both sides by -1
y=32
Plug this back into the equation to solve for x
x+32=51
Subtract 32 from both sides
x=19
They scored 19 1-point shots and 32 2-point shots.

Answer:
D. 17,15,13,11
Step-by-step explanation:
The expression states that the next term in this sequence is formed by subtracting 2 from the preceding (n-1) result. We know that for n = 1 that f(1) = 17.
f(n) is f(n-1) - 2
so
f(2) = f(1) - 2
f(2) = 17 - 2 or 15
f(3) = f(2) - 2
f(3) = 15 - 2 or 13
f(4) = f(3) - 2
f(4) = 13 - 2 or 11
. . . .
. . . .
. . . .
and so on.
Answer:
D and B
Step-by-step explanation:
using the recursive formula and f(1) = 17 , then
f(2) = f(1) - 2 = 17 - 2 = 15
f(3) = f(2) - 2 = 15 - 2 = 13
f(4) = f(3) - 2 = 13 - 2 = 11
first 4 terms are 17, 15, 13, 11 → D
-------------------------------------------------------
Using the recursive formula and f(1) = 5 , then
f(2) = 4f(1) = 4 × 5 = 20
f(3) = 4f(2) = 4 × 20 = 80
f(4) = 4f(3) = 4 × 80 = 320
first 4 terms are 5, 20, 80, 320 → B

Solve for k in the following equation: E = 2kn
Answer:
(E/2)/n = k
So when doing this you have to isolate K since your solving for “k”.
In order to do this you have to perform the inverse of every variable or number in order to isolate K.
In this case you divide 2 and then N.

a gardener uses a triangular prism shpapped clay pot to plant flowers. the triangular base is 3 units along the base and 5 units high. the pot has a height of 26 units. what is the volume
The volume of the triangular prism clay pot is 195 unit³
Volume of a triangular prism:v = BHwhere
B = base area
H = height of the prism
Therefore,
Base area = area of a triangle
area of a triangle = 1 / 2 × base × height
Therefore,
B = 1 / 2 × b × h
b = 3 units
h = 5 units
B = 1 / 2 × 3 × 5
B = 15 / 2
B = 7.5 units²
Therefore,
H = 26 units
B = 7.5 units²
V = 7.5 × 26
V= 195 unit³

given the diagram below, what is COS(45º)?
Answer:
1 / [tex]\sqrt{2}[/tex]
Step-by-step explanation:
In a 45,45,90 triangle, the two legs of the triangle are equal to each other and the hypotonus being x [tex]\sqrt{2}[/tex]. So that make the unknown sides 6 and 6[tex]\sqrt{2}[/tex]. When solving for cos(45) you divide the leg adjacent to the 45 (6) by the hypotonus (6[tex]\sqrt{2}[/tex]) This gives you 6/6[tex]\sqrt{2}[/tex]. You can simplify the 6s to get 1 / [tex]\sqrt{2}[/tex]
Explanation:
This is a 45-45-90 right triangle, aka isosceles right triangle.
The two legs are 6 units each, because the legs of isosceles triangles are the same length.
The hypotenuse is 6*sqrt(2) through the use of the pythagorean theorem.
From here we can say:
[tex]\cos\left(\text{angle}\right) = \frac{\text{adjacent}}{\text{hypotenuse}}\\\\\cos\left(45^{\circ}\right) = \frac{6}{6\sqrt{2}}\\\\\cos\left(45^{\circ}\right) = \frac{1}{\sqrt{2}}\\\\[/tex]
It turns out that the '6' has nothing to do with the final answer, since the '6's cancel out. So we could change that 6 to any number we want, and the answer would still be the same.
Side note: Rationalizing the denominator will have [tex]\frac{1}{\sqrt{2}} = \frac{\sqrt{2}}{2}[/tex]

Gaming systems are on sale for 20% off the original price (g), which can be expressed with the function p(g) = 0. 8g. Local taxes are an additional 12% of the discounted price (p), which can be expressed with the function c(p) = 1. 12p. Using this information, which of the following represents the final price of a gaming system, with the discount and taxes applied? g[c(p)] = 0. 896g c[p(g)] = 0. 896g g[c(p)] = 1. 92p c[p(g)] = 1. 92p.
Final price of gaming system, with the discount 20% and taxes 12% applied is represented by composite function as,
[tex]c[p(g)] =0.896p \\[/tex]
What is composite function?Composite function is the function in which the one function is dependent on the other function. The one function is written inside the other function to show the such relationship between the two function.
Given information-
The sale on the gaming system are of 20 percent.
The total local tax on the discounted price is 12%.
The function which expressed the sale on gaming system is,
[tex]p(g) = 0. 8g[/tex]
The function which expressed the tax on discounted price is,
[tex]c(p) = 1. 12p.[/tex]
The sale on the gaming system are of 20 percent and The function which expressed the sale on gaming system is,
[tex]p(g) = 0. 8g[/tex]
Now the local tax is applied on the discounted price after the 20 percent sell. Thus the function of discounted price will be a written inside the function of local tax as,
[tex]c[p(g)] =1.12p(0.8) \\c[p(g)] =0.896p \\[/tex]
The above function is the required function, which tales the final price of the gaming system is 0.896 times the original price.
The final price of gaming system, with the discount 20% and taxes 12% applied is represented by composite function as,
[tex]c[p(g)] =0.896p \\[/tex]

Kathrine makes bracelets at a rate represented by a algebraic equation y=4× where x is the number of days, and y is the total number of bracelets made. Katherine also makes necklaces at the rate shown in the graph. How many more days will it take katherine to make 20 necklaces than it will take her to make 20 bracelets?
Using the algebraic equation and the graph given, number of extra days it will take Kathrine to make 20 necklaces than it will take her to make 20 bracelets is: 8 - 5 = 3 days.
What is an Algebraic Equation?An algebraic equation, like the one given, models word problems, and can be used to find unknown numbers.
Thus:
y = 4× represents the rate Kathrine uses to make bracelets, where,
x = number of days
y = total number of bracelets made
Find the number of days (x) it takes to make 20 bracelets.
Substitute y = 20 into y = 4x:
20 = 4x
20/4 = x
x = 5 days.
Create an algebraic equation in the form of, y = kx, for the rate of necklace Kathrine makes using the graph.
Thus, using the point, (4, 10), substitute x = 4 and y = 10 into y = kx and find k.
10 = k(4)
10/4 = k
k = 2.5
The algebraic equation for rate of necklace made is: y = 2.5x
Number of days Kathrine will use to make 20 necklaces would be:
20 = 2.5x
20/2.5 = x
x = 8 days.
Number of days to make 20 bracelets = 5 days
Number of days to make 20 necklaces = 8 days
In summary, using the algebraic equation and the graph given, number of extra days it will take Kathrine to make 20 necklaces than it will take her to make 20 bracelets is: 8 - 5 = 3 days.
