2x-3x+5=4x-3
combine terms: -1x+5=4x-3
add across: 5+3=4x+1x
solve: 8=5x
answer: 5/8=x
The amount of money that Davis has in this scenario is; $50
<h3>How to solve algebra word problems?</h3>
Let the amount of money he has be $X.
Now, if he buys 10 notebooks, he will have $10 left. Thus;
X - 10n = 10 -----(1)
If he buys 15 notebooks, he will be $10 short. Thus;
X - 15n = -10 ------(2)
Subtract eq 1 from eq 2 to get;
-5n = -20
n = -20/-5
n = 4
Thus;
X - 10(4) = 10
X = 10 + 40
n = $50

A(8) = A(1) * 1.75^(8-1) = 10 * 1.75^7 = 502.65
Answer:
An exponential model can best describe the data
Step-by-step explanation:
The graph of the data set is shown in the attachment below. An exponential model can best describe the data. The respective equation can also be found in the graph
Answer:
12
Step-by-step explanation:
while f(x) = f(-1) then we can solve the equation
Y=-3(x-4)+3x
f(x)=-3(x-4)+3x
f(-1)=-3(x-4)+3x
=-3((-1)-4)+3(-1) = 12
Y=12
