Answer:
Step-by-step explanation:
Let the amount of flour left be .
Initial amount of flour = 18 cups
Cups used for 1 batch of muffins = 3
∴ Cups used for batches =
Amount left in the container is given as:
Therefore, the equation to show how much flour is left in the container after x batches of muffins is .
The graph of it is shown below.
Find the x and y intercepts and then join the line.
At x intercept,
So, x intercept is
At y intercept, ,
So, y intercept is
Join these two points to plot the graph.
B=s-15 b=boots, s=shoes
2b+3s=120
2(s-15)+3s=120
2s+3s-30=120
5s=150
s=30$. b=s-15
b=15$
Answer:
$1013.42
Step-by-step explanation:
This one would be similar to the previous.
Initial investment, P = 800
Annual Interest rate, r = 12%
Number of compouding in a year, n = 4
Time Period, t = 2 years
Using formula:
Future value,
A = P(1+r/n)^(nt)
= 800 (1+0.12/4)^(4*2)
= 800 (1.03)^(8)
= 1013.42 (to the nearest cent)
Answer:
Slope-intercept form is y=mx+b (m = gradient, b = y-intercept)
So we want to make y the subject.
3x + 4y =-24
4y = -3x - 24
y = (-3/4)x - 6
