1. Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days. Peter’s Deliveries
(a) What is the equation of the line, first written in point-slope form and then written in slope-intercept form? Show how you determined the equation. (b) Based on the linear model, predict how long it initially took Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences
Answer:
y - 12 = -3 (x - 6)
y = -3x +6
6 minutes
The delivery times decreased by 3 minutes each day
Step-by-step explanation:
Point Slope:
Let's pick a point first (6,12)
The Slope of the line is -3
y - y1 = m (x - x1)
y - 12 = -3 (x - 6)
Slope-intercept:
The y-intercept is not shown on the graph but we can turn the point slope form of the equation to slope-intercept
y - 12 = -3x + 18
y = -3x +6
y-intercept:
y = mx + b
y = -3x + 6
m = 6
6 minutes
Slope:
we already know the slope is 3
The delivery times decreased by 3 minutes each day

A sandwich shop serves 4 ounces of meat and 3 ounces of cheese on each sandwich. After making sandwiches for an hour, the shop owner has used 91 combined ounces of meat and cheese. How many combined ounces of meat and cheese are used on each sandwich?
Answer:
Step-by-step explanation:
Given : For each sandwich:
Quantity of meat used = 4 ounces
Quantity of cheese used = 3 ounces
The combined ounces of meat and cheese are used on each sandwich =
Quantity of meat used + Quantity of cheese used
= 4 ounces + 3 ounces
= 7 ounces
Hence, The combined ounces of meat and cheese are used on each sandwich = 7 ounces
An SUV costs $26,425 and costs an average of $0.18 per mile to maintain. A hybrid model of the SUV costs $33,195 and costs an average of $0.13 per mile to maintain. After how many miles will the cost of the gas-only SUV exceed the cost of the hybrid?
Answer:
135,400 miles
Step-by-step explanation:
SUV cost = $26,425 + $0.18m
= 26,425 + 0.18m
Hybrid SUV cost = $33,195 + $0.13m
= 33,195 + 0.13m
Where,
m = number of miles
Equate the cost of the two SUVs
33,195 + 0.13m = 26,425 + 0.18m
33,195 - 26,425 = 0.18m - 0.13m
6,770 = 0.05m
divide both sides by 0.05
m = 6,770 / 0.05
= 135,400
m = 135,400 miles
The gas-only SUV exceed the cost of the hybrid after 135,400 miles

In this problem, is X 13/21?
If X is 13/21 what is the answer to this problem?
-2/3 x 13/21 + 3/7
If X isnt 13/21, what is X?
Answer:
x = - [tex]\frac{3}{28}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{2}{3}[/tex] x + [tex]\frac{3}{7}[/tex] = [tex]\frac{1}{2}[/tex]
Multiply through by 42 ( the LCM of 3, 7 and 2 ) to clear the fractions
- 28x + 18 = 21 ( subtract 18 from both sides )
- 28x = 3 ( divide both sides by - 28 )
x = - [tex]\frac{3}{28}[/tex]

This question is incomplete
Complete Question
Leah is creating satin bows for a wedding. From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon. How much ribbon does Leah have left?
A.) -12 meters
B.) -5 meters
C.) 5 meters
D.) 12 meters
Answer:
C.) 5 meters
Step-by-step explanation:
From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon.
Step 1
3 4/9 meters + 6 5/9 meters
Least Common Denominator = 9
(3+ 6) + [ 4/9 + 5/9)
9 + [4 + 5/9]
9 + [9/9]
9 + 1
= 10 meters
This means, the total number of ribbons cut is 10 meters
The amount of ribbon Leah has left =
Initial length of ribbon - Amount of ribbon cut
= 15 meters - 10 meters
= 5 meters
Hence, Leah has 5 meters long of ribbon left
Answer:
the answer is 5 meters left

in the diagram O is the center of the circle XY is a diameter
help and explain please
also giving a BRAINLIEST!
Answer:
see explanation
Step-by-step explanation:
The angle at the circumference b , is half the angle subtended at the centre by the arc XZ, that is
b = 0.5 × 72 = 36
OZ and OX are congruent ( both radii of the circle )
Thus Δ OXZ is isosceles with base angles congruent, thus
a = [tex]\frac{180-72}{2}[/tex] = [tex]\frac{108}{2}[/tex] = 54
∠ XZY = 90° ( angle in a semicircle is right )
The domain of a function is given by {-4,2,8}. If the function is defined by y= x +1 /3 ,then which of the following values is a member of the range?
Answer:
{-1, 1, 3}
Step-by-step explanation:
Given the function
y = (x + 1)/3
The domain are the input value x while the range are the output values given the input value x;
Given the domain {-4, 2, 8}
when x = -4;
y = (-4+1)/3
y = -3/3
y = -1
when x = 2;
y = (2+1)/3
y = 3/3
y = 1
when x = 8;
y = (8+1)/3
y = 9/3
y = 3
Hence the member of the range are {-1, 1, 3}

Are the expressions 8a2 - 4b + 7a2 and 5(3a2 - 2b) + 6b equivalent? Explain your reasoning.
Answer:
Yes, The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
Step-by-step explanation:
To answer the question you must simplify each expression, then compare them to find if they are equivalent or not
∵ The 1st expression = 8a² - 4b + 7a²
→ Add the like terms
∴ The 1st expression = (8a² + 7a²) - 4b
∴ The 1st expression = 15a² - 4b
∵ The 2nd expression = 5(3a² - 2b) + 6b
→ Multiply the bracket by 5
∴ The 2nd expression = 5(3a²) - 5(2b) + 6b
∴ The 2nd expression = 15a² - 10b + 6b
→ Add the like terms
∵ The 2nd expression = 15a² + (-10b + 6b)
∴ The 2nd expression = 15a² + -4b
→ Remember (+)(-) = (-)
∴ The 2nd expression = 15a² - 4b
∵ The 1st expression = The 2nd expression
∴ The two expressions are equivalent
∴ The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
