Answer:
D. (4, 5)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
y = 1/2x + 3
<u>Step 2: Solve for</u><u><em> x</em></u>
- Substitute in <em>y</em>: x + 1 = 1/2x + 3
- Subtract 1/2x on both sides: 1/2x + 1 = 3
- Subtract 1 on both sides: 1/2x = 2
- Divide both sides by 1/2: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = 4 + 1
- Add: y = 5
<u>Step 4: Graph</u>
<em>We can confirm our answer.</em>
Answer:
0.77 M
Step-by-step explanation:
I'm going to assume this is a half-circle
Formula:
A = (πr^2)/ 2
D = 1.4
r = 0.7
A = (π 0.7^2)/2
A = (0.49π)/2
A = 0.7693
A = 0.77
Considering that 160,000 is the y-intercept of the function, it's significance is given by:
the initial population at the time of the estimation.
<h3>What is the y-intercept of a function f(x)?</h3>
The y-intercept is f(0), that is, the value of y when x = 0, which is interpreted as the initial value of the function.
Researching this problem on the internet, it is found that f(0) = 160,000, hence the significance of 160,000 in the function is given by:
the initial population at the time of the estimation.

$4.30X40%=1.72
4.30-1.72=2.58
2.58X6%=.15
2.58+.15=2.73
Final price: $2.73
Answer:
11 pt
Step-by-step explanation:
There are 2 pints in one quart. This means that there are 10 pints in 5 quarts, plus 1 would be 11.
