Write a rule for the linear function in the table.
f(x) = x – 4
f(x) = x + 4
f(x) = 3x
f(x) = x – 5
Answer: all on brainly
f(x) = –4x is a function rule for the table.
Step-by-step explanation: all on brainly
f(x)=x-4 is the answer i believe
Answer :
The function is
Step-by-step explanation:
Given values in table :
x f(x)
3 -1
4 0
5 1
6 2
Here we see there is a difference of 4 in the values of x and f(x)
i.e. 3-(-1)=4
or 4-0=4
Similarly 5-1=4
6-2=4
So x-F(x)=4
Adding F(x) -4 both sides
x-F(x) +F(x) -4=4+F(x) -4
We have F(x)= x-4

how do you subtract a power from a power
Answer:
Am not sure if u subtract it cuz
if x^2^2 u multiply instead of subtracting & x = 4
It’s in division where u subtract and if it’s same base like x^2^2 •x^3 then u add & u get 4+3 = x^7

What is the value of (x)
Answer:
x = 7
Step-by-step explanation:
multiply 7 on both sides to get x = 7 x 1. x = 7
Answer:
x=7
Step-by-step explanation:
Because 7*1 equal 7
And 7 divided by 7 is 1

HELPPP!!! ASAP
Answer:
see below
Step-by-step explanation:
x = 3 × 7 - 4
X = 21 - 4
X = 17 simply put the value of y
Answer:
x=17
Step-by-step explanation:
x=3(7)-4
x=21-4
x=17
2x+y+2z=7, 2x-y+2z=1, 5x+y+5z=13
Answer:
y = 3
x = 2 - z
Step-by-step explanation:
We have the system:
2*x+y+2*z=7
2*x-y+2*z=1
5*x+y+5*z=13
In the first and second equations we have the term (2*x + 2*z) = A
Then we can rewrite the first two equations as:
A + y = 7
A - y = 1
isolating A in the first equation, we get:
A = 1 + y
Now we replace this in the other equation:
(1 + y) + y = 7
1 + 2*y = 7
2*y = 6
y = 3.
then:
A + y = 7
A + 3 = 7
A = 7- 3 = 4
A = 2*x + 2*z = 4.
Now let's go to the third equation:
(5*x + 5*z) + y = 13
we can rewrite the thing inside the parentheses as:
(5/2)*(2*x + 2*y) + y = 13
And we know that:
2*x + 2*z = 4
y = 3
then this can be written as:
(5/2)*(4) + 3 = 5*2 + 3 = 13
Then we can conclude that:
y = 3
2*z + 2*x = 4
2*(z + x) = 4
(z + x) = 4/2 = 2
x = 2 - z
Notice that the solution is not only a point, we have infinite solutions for this problem.
1.k + 9c use k = 5 and c = -9*
Step-by-step explanation:
Here
k = 5, c = - 9
Then.
k + 9c
= 5 + 9 * (-9)
= 5 - 81
= -76

Find the coordinates of P so that P partitions segment A to B in the ratio 5:1 with A(2,
4) and B(8, 10).
Answer:
Point P has coordinates (7,9) (last choice)
Step-by-step explanation:
We are given the endpoints A(2,4) B(8,10) and the point P lying on the segment AB with the condition that P partitions it in the ratio 5:1.
This means the distances AP, PB and AB follow the conditions:
[tex]\frac{AP}{PB}=\frac{5}{1}[/tex]
AP+PB=AB
We can work with each coordinate separately. Suppose P has coordinates (x,y), thus:
[tex]x-x_a=5(x_b-x)[/tex]
[tex]x-x_a=5x_b-5x[/tex]
Adding 5x and subtracting:
[tex]6x=5x_b+x_a[/tex]
Dividing by 6:
[tex]\displaystyle x=\frac{5x_b+x_a}{6}[/tex]
Substituting:
[tex]\displaystyle x=\frac{5*8+2}{6}=\frac{42}{6}=7[/tex]
x=7
Now for the y-axis:
[tex]\displaystyle y=\frac{5y_b+y_a}{6}[/tex]
Substituting:
[tex]\displaystyle y=\frac{5*10+4}{6}=\frac{54}{6}=9[/tex]
y=9
Point P has coordinates (7,9) (last choice)
