I don't have the grid, so you'll have to actually plot the points and draw the line yourself. But I can help you calculate some points to plot.
Let's start off with 0 gallons of shampoo. So 0 times $40 = $0 and we have a fixed cost of $400. So the result is $0 + $400 = $400. And there's your first point (0, 400).
Now let's do 1 gallon of shampoo. 1 times $40 = $40 and we have to add the fixed cost of $400, so the result is $40 + $400 = $440. And your second point is (1,440).
In fact, we can create the function
c(x) = 40*x + 400
to express the cost for any amount of shampoo. So let's calculate 3 more points
c(2) = 40*x + 400 = 40 * 2 + 400 = 80 + 400 = 480
c(3) = 40*x + 400 = 40 * 3 + 400 = 120 + 400 = 520
c(4) = 40*x + 400 = 40 * 4 + 400 = 160 + 400 = 560
So 3 more points to plot are (2,480), (3,520), and (4,560).
And you've gotten your 5 points. They are (0,400), (1, 440), (2, 480), (3, 520), and (4, 560). Just plot them on your chart and draw a straight line through all 5 of them. And they will be in a straight line, if they're not, then you plotted them incorrectly.
Let x = cost of mango
y = c of apples
<span>8x+3y=18.
3x+5y=14.5 </span>
<span> </span>
<span>24x+9y=54
24x+40y=116
multiplying them with 3 and 8 resectively. </span>
<span>subtract one from the other we get </span>
<span>40y-9y=116-54 </span>
<span>31y=62 </span>
<span>y=2.
cost of apple=2$ per apple
</span><span>8x+3y=18,
8x+3(2)=18.
8x=12. x=12/8=1.5 </span>
<span>cost of mango i= 1.5 $ per mango
hope this helps</span>
Unclear plssss make it clear
Answer:
.05x+50=55
100 minutes
Step-by-step explanation:
simplify
.05x=5 (subtract 50 on both sides)
5/.05=x
100=x
she can call for 100 minutes
you can compare the length of sides of both the triangles...
