It's a linear function: y = mx + b.
The graph of the linear function is a straight line. Two points are enough for plotting a graph of this function.
The domain of this function is
We have the function: y= 3x - 6
We choose any two x and calculate the value of y:
for x = 0 → y = 3(0) - 6 = 0 - 6 = -6 → (0, -6)
for x = 2 → y = 3(2) - 6 = 6 - 6 = 0 → (2, 0)
Answer:
x=260 texts
Step-by-step explanation:
85=0.25x+20
Subtract 20 from each side.
65=0.25x
Divide both sides by 0.25.
260=x
260 texts plus the $20 flat fee will cost $85.
Answer:
17 * 2 = 34
-10 + (-9) = -19 or -29 + 10 = -19
Step-by-step explanation:
For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!
17*2 = 34 ✔
For the second, mess around with a few numbers add +10 and -29, COUNT DOWN from 10 and -29.
since + + + = + then - + - = -
if 10+9=19 then do the same with -
-10 + (-9) =-19

Answer:
(2x - 1)(5x - 2)
Step-by-step explanation:
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 10 × 2 = 20 and sum = - 9
The factors are - 5 and - 4
Split the middle term using these factors
10x² - 5x - 4x + 2 (factor the first/second and third/fourth terms by grouping )
= 5x(2x - 1) - 2(2x - 1) ← factor out (2x - 1)
= (2x - 1)(5x - 2)
Answer:
16)
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
