Answer:
The answer is incorrect; the plus sign should be a minus sign (apex)
Step-by-step explanation:
Problem 3: Let x = price of bag of pretzels Let y = price of box of granola bars
We have Lesley's purchase: 4x+2y=13.50
And Landon's: 1x+5y=17.55
We can use the elimination method. Let's negate Landon's purchase by multiplying by -1. -1x-5y=-17.55
We add this four times to Lesley's purchase to eliminate the x variable.
2y-20y=13.50-70.2
-18y=-56.7
y = $3.15 = Price of box of granola bars
Plug back into Landon's purchase to solve for pretzels.
x+5*3.15=17.55
x+15.75=17.55
x = $1.80 = price of bag of pretzels
Problem 4.
Let w = number of wood bats sold
Let m = number of metal bats sold
From sales information we have: w + m = 23
24w+30m=606
Substitution works well here. Solve for w in the first equation, w = 23 - m, and plug this into the second.
24*(23-m)+30m=606
552-24m+30m=606
6m=54
m=9 = number of metal bats sold
Therefore since w = 23-m, w = 23-9 = 14. 14 wooden bats were sold.
Answer:
B
Step-by-step explanation:
The domain is the set of x values for which the function is defined.
The range is the set of y values for which the function is defined.
Attached is the graph of the exponential function.
It is the basic graph of exponential function of y = 5^x which is shifted 6 units above (because of +6 at the end).
<em><u>Looking at the graph, the domain is the set of all x values.</u></em>
<em><u>The range is anything above 6.</u></em>
Correct answer is B.
I believe it’s AB AND DF, ZBAC = ZDEF
<span>-12 = pico(p)
So 10^-12 L = 1 pL
Use following to find the count of 10^-12 L are there in 2.3×10^-10 L
2.3×10^-10 / (10^-12) = 2.3×10^2 = 230 pL
-6 = micro (µ)
4.7×10^-6 g = 4.7 µg
1.85×10^-12 m = 1.85 pm
6 = Mega (M)
16.7×10^6 s = 16.7 Ms
So the answer is 16.7 Ms</span>
