The value of the function [tex]f(x)=7+2x[/tex] for [tex]f(7)[/tex] is 21.
The given functions are [tex]f(x)=7+2x[/tex] and [tex]g(x)=5x-2[/tex].
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.
To find [tex]f(7)[/tex], substitute [tex]x=7[/tex] in [tex]f(x)=7+2x[/tex], we get
[tex]f(7)=7+2(7)[/tex]
[tex]f(7)=21[/tex]
Therefore, the value of the function [tex]f(x)=7+2x[/tex] for [tex]f(7)[/tex] is 21.

Answer:
Y intercept = (0,-6)
X intercept = (9,0)
Step-by-step explanation:
To find the y-intercept of an equation, let x = 0 and then solve for y
6(0) - 9y = 54 (6 times 0 gives us 0)
0 - 9y = 54 (subtract 9y from 0 gives you -9)
-9y = 54 (divide both sides by -9, the left side cancels out and the right side gives you -6)
y = -6 and x = 0
To find the x-intercept of the equation just let y = 0 and then solve for x
6x - 9(0) = 54 (9 times 0 gives us 0)
6x - 0 = 54 (subtract 0 from 6x gives us 6x)
6x = 54 (divide both sides by 6, left side cancels, right side gives 9)
x = 9 and y = 0

The length of a rectangular hall exceeds its breadth by 7 m. If the breadth is decreased by 1 m and the length increased by 2 m, the area remains the same. Find the length and breadth of the hall.
Answer:
Step-by-step explanation:
Let the length be :x+7
Let the breadth be:x
After addition and subtraction
Length:x+7+2=x+9
Breadth:x-1
A.T.Q
x(x+7) = (x+9)(x-1)
x²+7x = x(x-1)+9(x-1)
x²+7x = x²-x+9x-9
x²+7x-x²+8x = 9
8x-7x = 9
So, Breadth: 9m
So, Length :16m

Suppose you know the area of the yard is 7,500 square feet. How can you find the value of a?
—help and it comes with a picture
Answer:
a = 50
Step-by-step explanation:
From the introduction, you know that the area is 3a^2
You also know that it is 7500 square feet. \
So the two must be equal
3a^2 = 7500 Divide by 3
a^2 = 7500/3
a^2 = 2500
The square root of 2500 is 50
sqrt(a^2) = sqrt(2500)
a = 50

which statement describes the solution to the system of equations?
Answer:
The solution is (3, 5).
Step-by-step explanation:
The solution to a system of equations is a point that satisfies both equations - that is, a point that you can input to both equations that makes both of them true. On a graph, you can find this solution by searching for the place where the lines intersect.
In this case, it looks like the lines intersect at the point (3, 5), so this is our final answer. Hopefully that's helpful! :)
The solution is (3, 5), this statement describes the solution to the system of equations.
Option B is correct.
Here, we have,
The statement that describes the solution to the system of equations where two lines intersecting at (3, 5) is:
"The point of intersection of the two lines is (3, 5)."
When two lines intersect at a single point, that point is the solution to the system of equations.
In this case, the coordinates (3, 5) represent the x and y values where the two lines cross each other.
This means that both equations are satisfied when x = 3 and y = 5.
The solution to a system of equations is a point that satisfies both equations - that is, a point that you can input to both equations that makes both of them true.
On a graph, you can find this solution by searching for the place where the lines intersect.
"The point of intersection of the two lines is (3, 5)."
Option B is correct.
