The equation of the function is f(x) = -5x + 10
How to determine the function equation?The points are given as:
x-intercept at (2,0) and a y-intercept at (0,10)
A linear function is represented as:
y = mx + b
Where b is the y-intercept.
The y-intercept at (0,10) means that:
b = 10
So, we have:
y = mx + 10
The x-intercept at (2,0) means that:
x = 2, when y = 0
Substitute these values in y = mx + 10
0 = 2m + 10
Subtract 10 from both sides
2m = -10
Divide both sides by 2
m = -5
Substitute m = -5 in y = mx + 10
y = -5x + 10
Hence, the equation of the function is y = -5x + 10

Evaluate the functions for the given input values.
f(x) = x² + 1
g(x) = 2f(x)
g(-3) =
g(2) =
g(7) =
Answer:
g(-3) = 20
g(2) = 10
g(7) = 100
Step-by-step explanation:
g(x) = 2f(x) tells us that g(x) is two times f(x). Instead of f(x) we can write (x² + 1).
g(x) = 2f(x)
g(x) = 2(x² + 1)
Multiply.
g(x) = 2x² + 2
Now that we have g(x) we just substitute values in the function.
g(-3) = 2(-3)² + 2
= 2(9) + 2
= 18 + 2
= 20
g(2) = 2(2)² + 2
= 2(4) + 2
= 8 + 2
= 10
g(7) = 2(7)² + 2
= 2(49) + 2
= 98 + 2
= 100

What is the value of x?
(Round your answer to
the nearest tenth.)
Answer:
x ≈ 8.7
Step-by-step explanation:
given 2 secants from an external point to the circle, then
the product of the external part of one secant and the entire secant is equal to the product of the external part of the other secant and the entire secant , that is
6(6 + x) = 4(4 + 18) ← distribute parenthesis on both sides
36 + 6x = 4 × 22 = 88 ( subtract 36 from both sides )
6x = 52 (divide both sides by 6 )
x ≈ 8.7 ( to the nearest tenth )

Answer:
Dimensions: 125 m x 250 m
Area: 31,250 m²
Step-by-step explanation:
Given information:
Total amount of fencing = 500mOnly 3 sides of the land need to be fencedFirst, let us assume that the land is rectangular in shape.
Let [tex]y[/tex] = length of the side opposite the river
Let [tex]x[/tex] = length of the other 2 sides of the land
Therefore, we can create two equations from the given information:
Area of land: [tex]A= xy[/tex]
Perimeter of fence: [tex]2x + y = 500[/tex]
Rearrange the equation for the perimeter of the fence to make y the subject:
[tex]\begin{aligned} \implies 2x + y & = 500\\ y & = 500-2x \end{aligned}[/tex]
Substitute this into the equation for Area:
[tex]\begin{aligned}\implies A & = xy\\& = x(500-2x)\\& = 500x-2x^2 \end{aligned}[/tex]
To find the value of x that will make the area a maximum, differentiate A with respect to x:
[tex]\begin{aligned}A & =500x-2x^2\\\implies \dfrac{dA}{dx}& =500-4x\end{aligned}[/tex]
Set it to zero and solve for x:
[tex]\begin{aligned}\dfrac{dA}{dx} & =0\\ \implies 500-4x & =0 \\ x & = 125 \end{aligned}[/tex]
Substitute the found value of x into the original equation for the perimeter and solve for y:
[tex]\begin{aligned}2x + y & = 500\\\implies 2(125)+y & = 500\\250+y & = 500\\y & = 250\end{aligned}[/tex]
Therefore, the dimensions that will give Christine the maximum area are:
125 m x 250 m (where 250 m is the side opposite the river)
The maximum area is:
[tex]\begin{aligned}\implies \sf Area_{max} & = xy\\& = 125 \cdot 250\\& = 31250\: \sf m^2 \end{aligned}[/tex]

Solve for the width in the formula for the area of a rectangle.
W=A-I
Xw = Al
W = 1/A
W = A/l
The expression w = A/l can be used to find the width of the rectangle if the area and length of the rectangle are given.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let's suppose the width of the rectangle is w and the length of the rectangle is l
Then, the area of rectangle(A) can be given as:
A = lw
divide by l on both the sides:
A/l = lw/l
A/l = w
or
w = A/l
Thus, the expression w = A/l can be used to find the width of the rectangle if the area and length of the rectangle are given.

A grocery store sells a bag of 6 oranges for $2.34. If Mav spent $1.95 on oranges, how many did she buy?
Answer:
5 oranges
Step-by-step explanation:
to solve this problem we need to make a cross-multiplication equation
2.34 is to 6 as 1.95 is to ?
? is the number of oranges that are needed to be found that were bought
2.34/6 = 1.95/?
Now we cross multiply 6 and 1.95 = 11.7
11.7/2.34 = 5
Give brainliest, please!
hope this helps :)
Answer: She bought 5 oranges
Step-by-step explanation:
We need to find out how much one orange costs first, so we do:
$2.34 ÷ 6or = $0.39
Thirty-nine cents is how much one orange cost.
Now you multiply the initial value of 1 orange by 5, so:
$0.39 x 5 = $1.95, $1.95 =5 oranges
You can also do $1.95 divided by $0.39 which is 5.
(you can multiply till you find the number or divide the given number by the other divided number)
Therefore, that means Mav bought 5 oranges.

Choice 4^th
Step-by-step explanation:
Given equation:
5/7 - []/6 = 16/42
To Find:
The missing numerator
Solution:
Let us assume that the missing numerator is x.
Then the equation will be:
[tex] = > \cfrac{5}{7} - \cfrac{x}{6} = \cfrac{16}{42} [/tex]
Solve the equation to get our solution.
[tex] = > \cfrac{5}{7} - \cfrac{1x}{6} = \cfrac{16}{42} [/tex]
You'll need to re-write this equation as:
[tex] = > \cfrac{ - 1x}{6} + \cfrac{5}{7} = \cfrac{8}{21} [/tex]
Subtract 5/7 from both sides:
[tex] = > \cfrac{ - 1x}{6} + \cfrac{5}{7} - \cfrac{5}{7} = \cfrac{8}{21} - \cfrac{5}{7} [/tex]
[tex] = > \cfrac{ - 1}{6} x = \cfrac{ - 1}{3} [/tex]
Multiply both sides by 6/-1:
[tex] = > \cfrac{ \cancel{- 1}}{ \cancel6} x \times \cfrac{ \cancel6}{ \cancel{- 1}} = \cfrac{ \cancel{- 1}}{ \cancel3} \times \cfrac{ \cancel6 {}^{2} }{ \cancel{ - 1} }[/tex]

You are correct.
B: Your slope is correct, 4.5
Equation of height: y = 4.5x + 3
C: It starts at 10 inches, so in y = mx + b, b = 10.
Now we find the slope from points on the graph (0, 10) and (3, 20).
slope = m = (20 - 10)/(3 - 0) = 10/3

A new movie was released over the weekend with 8 show times. 124 people saw the movie during the first 2 show times. If people come to the movie at the same rate, how many saw it over the weekend?
Answer:
496 people
Step-by-step explanation:
If 124 people attend 2 show times, in 8 show times (8 is four times of 2 show times; 8 / 2 = 4) there will be 124 · 4 people.
124 · 4 = 496.
In 8 show times, there will be 496 people who view the movie
(Or, if there are 124 people in 2 shows, it means that there were 62 people in each show [assuming the crowd was split evenly], and if there were 8 shows, there would be 62 · 8 people, 62 · 8 = 496)
