Slope is -1
Y intercept is 2
Answer:
The two linear equation
x + y = 19.... Equation 1
0.55x + 0.75y = 12.65... Equation 2
Nedra purchased
9 Apples and 11 Oranges
Step-by-step explanation:
Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?
Let the number of apples be represented by x
The number of oranges by represented by y.
Hence,
Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,
Hence:
x + y = 19..... Equation 1
x = 19 - y
$0.55 × x + $0.75 × y = $12.65
0.55x + 0.75y = 12.65.....Equation 2
Hence: we substitute 19 - y for x in Equation 2
0.55(19 - y) + 0.75y = 12.65
10.45 - 0.55y + 0.75y = 12.65
-0.55y+ 0.75y = 12.65 - 10.45
0.20y = 2.2
y = 2.2/0.20
y = 11 oranges
x = 19 - y
x = 19 - 11
x = 8 Apples
So for example B(4,1) so x=4, y=1
->B'(4-2,1-4)
->B'(2,-3)
->A'(1-2,1-4)
->A'(-1,-3)
->C'(4-1,-2-4)
->C'(3,-6)
->D'(1-2,-2-4)
->D'(-1,-6)
so the image of the rectangle ABCD->A'B'C'D'
<span>Answer: 39 quarter
The value of a stock share in a new technology company has been increasing at a rate of 8.6% quarterly. That means the stock will increase by 8.6%/4= 2.15% rate per quarter. The exponent function to find the number of money the investor have would be:
</span>an= $102.15(1.0215)^t
<span>
The time needed for getting </span>$233.10 would be:
an= $102.15(1.0215)^t
$233.10= $102.15(1.0215)^t
2.2819 * $102.15= $102.15( 1.0215)^t
2.2819 = (1.0215)^t
t= log1.0215 2.2819
t= 39
