Amelia was showing off her basketball skills. She scored a total of 14 shots for a total of 32 points. How many 2 point and 3 point shots did she make?
Answer:
Step-by-step explanation:
x+y=14
y=14-x
2x+3y=32, using y=14-x we have
2x+3(14-x)=32
2x+42-3x=32
-x+42=32
-x=-10
x=10, and since y=14-x
y=14-10=4
So Amelia made 10 two-pointers and 4 three-pointers.
Evaluate using the functions f(x) = 3x–8 and g(x) = -x2+ 4x–11.
1 . f(10+10
2. g(-9)+7
3. -2xg(4)
4. f(-4)-g(7)
5. Given f(x)= 9 –2x, if f(x)= 19, find the value of x.
The value of f(10)+10 for the given function is 32.
The given functions are f(x) = 3x-8 and g(x) = -x²+ 4x-11.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) Put x=10 in the function f(x) = 3x-8, we get
f(10)=3(10)-8
= 22
So, f(10)+10
= 22+10=32
2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get
g(-9)=-(-9)²+4(-9)-11
= -81-36-11
= -128
So, g(-9)+7
= -128+7
= -121
3) Put x=4 in the function g(x) = -x²+ 4x-11, we get
g(4) = -(4)²+4(4)-11
=-16+16-11
=-11
Now, -2xg(4) =-2x(-11)
=22x
4) Put x=-4 in the function f(x) = 3x-8, we get
(-4)=3(-4)-8
= -20
Put x=7 in the function g(x) = -x²+ 4x-11, we get
g(7)=-(7)²+4(7)-11
= -49+28-11
= -32
5. Given f(x)= 9 –2x, if f(x)= 19
Now, 9-2x=19
⇒ -2x=10
⇒ x=-5
Therefore, the value of f(10)+10 for the given function is 32.

Line A is represented by the following equation: x + y = 2
What is most likely the equation for line B so the set of equations has no solution? (4 points)
Group of answer choices
x + 2y = 2
2x + 2y = 4
2x + y = 2
x + y = 4
Answer:
x+y=4
Step-by-step explanation:
No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution

Answer:
(x, y) = (3, 7)
Step-by-step explanation:
If you divide the second equation by 2, it becomes ...
-x +2y = 11
Adding this to the first equation gives you the value of y:
(x -y) +(-x +2y) = (-4) +(11)
y = 7 . . . . . . . . simplify
The first equation can be rearranged to give an expression for x:
x = y -4
x = 7 -4 = 3
Then the solution is seen to be (x, y) = (3, 7).

You are taking a trip at the same time as another
family. Your family traveled 1.900 miles in 2 days,
their family traveled 2.700 miles in 3 days. Who is
traveling fastera
Answer:
My family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.
Step-by-step explanation:
Since I am taking a trip at the same time as another family, and my family traveled 1,900 miles in 2 days, while their family traveled 2,700 miles in 3 days, to determine who is traveling faster the following calculation must be performed:
1,900 / 2 = 950
2,700 / 3 = 900
Thus, my family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.

The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.
Calculation of the height:Since
HEIGHT Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow.
So,
6 feet tall = 12
Now for 11 foot it should be half like 5.5

Answer:
a-16cm
b-12cm if not iwill look again
Step-by-step explanation:
Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.
The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units
where b is the length of the base and h is the height or altitude
For parallelogram (a),
length of the base = 4 cm
the height or altitude = 4 cm
Area of parallelogram (a) = b × h = 4 × 4
Area of parallelogram (a) = 16 cm²
For parallelogram (b),
length of the base = 2 cm
the height or altitude = 6 cm
Area of parallelogram (b) = b × h = 2 × 6
Area of parallelogram (b) = 12 cm²

The correct step to translate f(x) = 3ˣ to g(x) = 3ˣ⁺¹ + 4 is:
Shift f(x) = 3ˣ one unit to the right and four units up. So option C is correct
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
This means that for every x value,
we add 4 to the y-value and move the y-value one unit to the right.
To see this graphically, imagine a graph of the equation f(x) = 3x.
This graph will be a line that passes through the origin (0,0) and has a slope of 3.
If we shift this line one unit to the right, then the x-intercept (the point where the line crosses the x-axis) will change from (0,0) to (1,0).
If we also add 4 to the y-value of every point on this line,
then the y-intercept (the point where the line crosses the y-axis) will change from (0,0) to (0,4).
The resulting graph will be the graph of the equation g(x) = 3ˣ⁺¹ + 4.
