find value of x so that f(x)=7
Answer: -3
Step-by-step explanation:
0,4
2,2
Find slope: 2 - 4 = -2
2 - 0 = 2
-2/2 = -1 is slope
7 = -1x + 4
subsitute -1 for x
7 = -1(-1) + 4
1 + 4
The required simplified value of the x is -3 for f(x) = 7.
Given that,
To determine the value of x so that f(x)=7.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
As shown in the graph,
The slope of the line is m = -1
And points through which the line is passing are (0,4) and (4, 0)
The equation of the line is given as,
(y - 4) = -1 (x - 0)
y -4 = -x
y + x = 4
Now,
y = 4 - x
putting y = f(x)
f(x) = 4 - x
Now,
we have f(x) = 7
7 = 4 - x
x = -3
Thus, the required simplified value of the x is -3 for f(x) = 7.

A quadratic function has a line of symmetry at x = –3.5 and a zero at –9. What is the distance from the given zero to the line of symmetry? What is the other zero of the quadratic function?
Given:
A quadratic function has a line of symmetry at x = –3.5 and a zero at –9.
To find:
The other zero.
Solution:
We know that, the line of symmetry divides the graph of quadratic function in two congruent parts. So, both zeroes are equidistant from the line of symmetry.
It means, line of symmetry passes through the mid point of both zeroes.
Let the other zero be x.
[tex]-3.5=\dfrac{(-9)+x}{2}[/tex]
Multiply both sides by 2.
[tex]-7=-9+x[/tex]
Add 9 on both sides.
[tex]-7+9=-9+x+9[/tex]
[tex]2=x[/tex]
Therefore, the other zero of the quadratic function is 2.
Answer: A=0, B=6, C=4.
The axis of symmetry is x = ½
The smaller zero is -2
The larger zero is 3

value
Answer:
(21.9, 66.3)
Step-by-step explanation:
Given the coordinates A (25.5, 60.1) and C (18.3, 72.5)
The formula for calculating the midpoint is expressed as;
M = {(x1+y1)/2, (y2+y1)/2}
X = (x1+y1)/2
Y = (y2+y1)/2
From the given coordinates A (25.5, 60.1) and C (18.3, 72.5)
x1 = 25.5, y1= 60.1, x2 = 18.3 and y2 = 72.5
X = (25.5+18.3)/2
X = 43.8/2
X = 21.9
Y = (72.5+60.1)/2
Y = 132.6/2
Y = 66.3
The midpoint of the coordinates M will be M(21.9, 66.3)

Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P,P, in terms of x,x, representing Cooper's total pay on a day on which he sells xx dollars worth of computers.
Answer:
P= 0.015x+60
Step-by-step explanation:
thats the right answer
If Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Then P = 0.015x + 60 is total pay.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Cooper's base pay is $60 per day
He gets $60 even for not selling computers,
meaning P= 60 when x=0, which is the y-intercept.
Now if Cooper makes a commission of 1.5% for all sales,
His earning will be increased by 1.5%.
The percentage value should be changed to decimal value. By Dividing 1.5 by 100
1.5/100=0.015
The amount of money earned in a given day increases $0.015 for each $1 of sales made.
Here x, representing Cooper's total pay on a day on which he sells x dollars of worth computers.
P = 0.015x + 60
Hence P = 0.015x + 60 is the total pay of cooper .

Solve: 13x+8 = 4x + 1
Answer:
x = -7/9
Step-by-step explanation:
First, subtract 8 from both sides of the equation.
13x = 4x - 7
Next, subtract 4x from both sides of the equation.
9x=-7
Divide both sides of the equation by the same term
x = -7/9
