HELP PLEASE Sam and George both worked hard over the summer. Together they earned a total of $525. George earned$75 more than Sam.
a. Write a system of equations for the situation. Use s for the amount Sam earned and g for the
amount George earned.
b. Graph the equations in the system. Be sure to label all axes and show your scale.
c. Use your graph to determine how much each person earned.
Answers
Answer:
Step-by-step explanation:
g = s + 75
g + s = 525
That's just the answer for (a). You'll have to graph it yourself.
Guide to the methodology:
You need to plot 2 points for each equation and draw a line between the points. Where the two lines intersect gives you the values that solve the equations.
To get your co-ords,
Let g = 0
s = -75
Create a graph with g as one axis and s as the other. Plot a point of (0,-75)
Let s = 0
g = 75
Plot another point (0,75)
Draw a line between the two points. This is your line for g = s +75
You then need to plot a line for the second equation.
Let g = 0. S = 525. First co-ordinate is (0,525)
Let s = 0. G = 525. Second co-ordinate is (525,0)

(4 + 5) is greater than 3·4 + 5 by 8.
Step-by-step explanation:
- Step 1: Value of (4 + 5) = 9
- Step 2: Value of 3·4 + 5 = 12 + 5 = 17 (as per BODMAS rule)
- Step 3: Find the difference between the two.
⇒ 17 - 9 = 8

Answer:
Height of lamppost would is 12.5 feet.
Step-by-step explanation:
We are given a 5 feet tall boy form shadow with 8 foot.
As we know height is directly proportional to shadow length.
where, h is height of boy, k is constant of proportionality and s is shadow length.
when h=5 , s=8
5=8k
We need to find height when shadow length is 20 feet.
Thus, Height of lamppost would be 12.5 feet.
20*5 = 8x
x = 12,5
Therefore height of the lamp is 12.5 feet :)
b y = 2.65x-2.50
c y = 2.50x+2.65
d y = 2.65x+2.50
Answers
Answer:
d y=2.65x+2.50
Step-by-step explanation:
The correct answer would be d because y is the total cost with a start value of 2.50 and a slope of 2.65x. Then you would just replace the equation y=mx+b with these values
