Answer:
y = 1/3*x -3
Step-by-step explanation:
Method 1:
Grab two random points from the line.
(0,-3) and (3,-2)
Using the Point-Slope Form solve for m.
(-3 - (-2)) = m * (0 - (3))
-1 = m * (-3)
m = 1/3
Turning Point-Slope form into Slope intercept Form.
(y - (-3)) = 1/3 * (x - 0)
y + 3 = 1/3x
y = 1/3 - 3
Method 2:
Look at the y-intercept since y-int becomes our b. b = -3
From the y-int count rise/run as thats our Slope m. m = 1/3
Slope-intecept Form:
y = 1/3*x -3
Answer:
sold 120 chocolate bars
sold 140 peanut butter bars
Step-by-step explanation:
x = peanut butter bars
y = chocolate bars
x + y = 260, total lbs
0.25x + 0.30y = 71, money
solve double variable equation
multiply -4 on both sides for 2nd equation
-x + -1.2y = -284
add both equations together
-0.2y = -24
y = 120
x = 260 - 120
x = 140
sold 120 chocolate bars
sold 140 peanut butter bars

Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
Answer:
<u>Domain = R - {3/2}</u>
Step-by-step explanation:
The domain of a rational function consists of all the real numbers x except those for which the denominator is 0
The given function is :
We need to find the zeros of the denominator
∴ 2x - 3 = 0 ⇒ add 3 to both sides
∴ 2x = 3 ⇒ divide both side by 2
∴ x = 3/2
The domain will be all real number except the zeros of the denominator.
So, Domain = R - {3/2}
Also, see the attached figure that represents the given function.
