Answer:
f( - 4) = 21Step-by-step explanation:
[tex]f(x)=-2x+13[/tex]
To find f(-4), substitute the value of x that's - 4 into f(x). That is for every x in f(x) replace it with - 4
We have
[tex]f( - 4) = - 2( - 4) + 13 \\ = 8 + 13 \\ = 21 \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
f(-4) = 21Hope this helps you
I already got 842 squared=c2 I just need help with simplest radical form
Answer:
The answer is 29.
Step-by-step explanation:
The steps to do this :
[tex] {c}^{2} = {20}^{2} + {21}^{2} [/tex]
[tex] {c}^{2} = 841[/tex]
[tex]c = \sqrt{841} [/tex]

I need this 6 questions by tomorrow
Answer:
The answwer for question 6 is -3x+10xw
Step-by-step explanation:
When given a question like this, you have to separate the variables by adding the one with the same variable together. If you add 5x and -8x you will get -3x and if you add 7w with -7w, you'll get 0w which isn't needed in the equation. 20xw would be alone.
find the y-intercept of the graph of 2x-5y=10
Answer:
y-intercept: ( 0 , − 2 )
Step-by-step explanation:
To find the y-intercept, substitute in 0 for x and solve for y
Answer:
(0,-2)
Step-by-step explanation:
Start with:
[tex]2x-5y=10[/tex]
We are going to want this equation in slope-intercept form.
[tex]y=mx+b[/tex]
[tex]mx=slope[/tex]
[tex]b=y-intercept[/tex]
To get the equation in slope intercept from, start by subtracting [tex]2x[/tex] from both sides of the equation:
[tex]-5y=-2x+10[/tex]
Now, divide both sides of the equation by [tex]-5[/tex]:
[tex]y=-\frac{2}{5}x -2[/tex]
[tex]b=-2[/tex]
[tex](0,-2)[/tex]
What is 713.49 written in standard form as powers
Answer:
one hundred seven thirteen and forty nine hundreds standard form
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Mr. Gaines is catering his company picnic. He will pay $18.45 for 3 people to eat the barbecue lunch. At this rate, how many people can Mr. Gaines afford to feed on a budget of $1850.00? (Will give brainliest)
Answer: 300
Step-by-step explanation:
From the question, we are informed that Mr Gaines is catering his company picnic and that he will pay $18.45 for 3 people to eat the barbecue lunch. This means each person spends:
= $18.45/3
= $6.15
With a budget of $1850.00, the number of people that he'll be able to feed will be:
= $1850/$6.15
= $300 people

Tom is 4 more than twice andrews age. Sara is 8 less than 5 times ANdrews age. If tom and sara are twins how old is andrew
Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Given the function f defined by the formula f(x)=2x+1 find the following:
(a) f(4)
(b) f(-5)
(c) f(0)
(a) f(a)
Answer:
BELOWStep-by-step explanation:
[tex]f(x)=2x+1[/tex]
Substitute values into given equation :
[tex]f(4) = ?\\\\f(4) = 2(4)+1\\\\f(4) = 8+1\\\\f(4)=9[/tex]
(b).
[tex]f(-5) =2(-5)+1\\\\f(-5) = -10+1\\\\f(-5) = -9[/tex]
(c) .
[tex]f(0) =2(0)+1\\\\ f(0) = 0+1\\\\ f(0) =1[/tex]
(d) .
[tex]f(a) =2(a)+1\\\\ f(a) = 2a+1[/tex]

Answer:
56cm
Step-by-step explanation:
5488 is the area of the rectangle.
we know that length x width = area
so to find the with we do area/length
so, 5488/98 =56
Answer: 56 cm
Step-by-step explanation:
Area (A) = Length (L) × width (w)
Given: A = 5488 cm², w = 98 cm
A = L × w
5488 = L × 98
56 = L Divided 98 from both sides

If point (a,b) lies on the graph y=f(x), the graph of f^-1 (x) must contain point:
Given:
Point (a,b) lies on the graph [tex]y=f(x)[/tex].
To find:
The point which is must be lies on the graph of [tex]y=f^{-1}(x)[/tex].
Solution:
According to the definition of an inverse function, if a function is defined as
[tex]f=\{(x,y):x\in R,y\in R\}[/tex]
then, its inverse is defined as
[tex]f^{-1}=\{(y,x):x\in R,y\in R\}[/tex]
It means, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
We have a point (a,b) lies on the graph [tex]y=f(x)[/tex]. So, (b,a) must be lies on the graph of [tex]y=f^{-1}(x)[/tex].
Therefore, the correct option is (1).
By the definition of inverse function,the point (a,b) lies on the graph [tex]\bold{y= f(x).}[/tex] So, (b,a) must be lies on the graph of [tex]\bold{y=f^{-1} (x)}[/tex].
Given:
Point (a,b) lies on the graph y= f(x).
Find:
The graph of [tex]\bold{y=f^{-1} (x)}[/tex] must contain that point.
As per the definition of inverse function, if two one-to-one functions f(x) and g(x). If (f∘g)(x)=x and (g∘f)(x)=x. Then, we say that f(x) and g(x) are inverses of each other.
[tex]\bold{f=\{ (x,y):x\epsilon R,y\epsilon R\}}[/tex]
Then, its inverse is defined as
[tex]\bold{f^{-1} =\{ (y,x):x\epsilon R,y\epsilon R\}}[/tex]
Therefore, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
Thus, the point (a,b) lies on the graph [tex]y= f(x).[/tex] So, (b,a) must be lies on the graph of [tex]y=f^{-1} (x)[/tex].
