ƒ(x) = x − 9 if the domain is (3, -3, 0)
Answer:
f(3) = -6
f(-3) = -12
f(0) = -9
Step-by-step explanation:
Substitute each number for x.
f(3) = 3 - 9 = -6
f(-3) = -3 - 9 = -12
f(0 ) = 0 - 9 = -9
Answer:
{-6, -12, -9} is the range
Step-by-step explanation:
f(3) = 3 - 9 = -6
f(-3) = -3 - 9 = -12
f(0) = 0 - 9 = -9

Find the answer to the following system of equa
How many solutions are there for this system of
equations?
y= 2x + 3
y = -5x – 2
Answer:
One solution
Step-by-step explanation:
y = 2x + 3
y = -5x - 2
2x + 3 = -5x - 2
Add 5x to both sides;
7x + 3 = -2
Subtract 3 from both sides;
7x = -5
Divide both sides by 7;

Answer:
t=3
Step-by-step explanation:
10/4=5/2t-4
Cross-multiply
10*(2t−4)=(5)*(4)
20t−40=20
Add 40 to both sides.
20t−40+40=20+40
20t=60
Divide both sides by 20
20t/20=60/20
t=3
Hope it's right!
Answer:
t=3
Step-by-step explanation:
[tex]\frac{10}{4} = \frac{5}{2t-4}\\\\[/tex]
cross multiply now,
[tex]10(2t-4)=5(4)\\20t-40=20\\20t=20+40\\20t=60\\t=60/20\\t=3\\[/tex]

Equation of a line in standard formThe equation of line in standard form is expressed as Ax + By = C
Given the equation
y + 3 = 7(x - 2)
Expand
y + 3 = 7x - 14
y -7x = -14 - 3
-7x + y = - 17
7x - y = 17
Hence the standard form of the given expression is 7x - y = 17

Can I please have some HELP!!!
Answer:
-2/3 will be your answer
Step-by-step explanation:
I always like putting standard from into y=mx+b as you can just easily see the slope.
2x + 3y = 10
subtract 2x from each side
3y = -2x + 10
now to single out the 'y' divide by 3 on each side
y = -2/3 + 10/3
Hence, option A is your answer!

Eight more than 2 times a number is 22. Find the number.
Answer:
a number is 7
Step-by-step explanation:
First let's set up the equation:
8 + 2x = 22 (a number is replaced by x in this equation)
Now, to get x by itself and the answer, we need to cancel out the other numbers by adding, subtracting, multiplying, or dividing to both sides. I'm going to start with the eight, because it's the one with least complications.
8-8 + 2x = 22-8
We're left with 2x = 14
Now we divide both sides by two so x is by itself.
2x/2 = 14/2
Result:
x = 7
