Keith paid 8.44 each for 5 lizard toys and got 5 cages for 8.45 each with 5 20 bills . How much change did Keith recive
Answer:
19.51
Step-by-step explanation:
Answer:
15.55
Step-by-step explanation:
First, find the total cost of the items
8.44 * 5= 42.20
8.45 * 5= 42.25
42.20 + 42.25= 84.45
Then the amount of money given
20 * 5= 100
Last, subtract the cost from the amount given
100 - 84.45 =15.55
Question 7 using substitution if you don’t mind. Help please.
y= -2 and x= 1 according to the solution in the picture
Answer:
x = 1
y = -2
Step-by-step explanation:
3x - 2y = 7
4x + y = 2 then y = 2 - 4x
substitute for y:
3x - 2(2 - 4x) = 7
reduce:
3x - 4 + 8x = 7
11x = 11
x = 1
y = -2

Brian jogged 2 miles in 30 minutes. At this rate, how many miles will he jog in 2 hours?
4 miles
8 miles
6 miles
10 miles
Answer:
8miles
Step-by-step explanation:
If Brian jogged 2 miles in 30 minutes, this is expressed as;
2miles = 30minutes
To calculate the distance covered in 2hrs, we can say
x miles = 2hrs (120minutes)
Divide both expressions
2/x = 30/120
Cross multiply
30x = 2 * 120
30x = 240
x = 240/30
x = 8
hence he covers 8miles in 2hrs
EXAMPLE How many inches are in 6 miles? (1 mile=5280 feet, 1 foot=12 inches)

What is the domain of the function y = log(x + 3)?
O
(-00,00) (-00,00)
(-00, -3)
(0,co)
(-3,0)
DONE
Answer:
the domain for the function y=log(x+3) is (-3,oo).
The domain of the function y = log(x + 3) is (−3, +∞), or in interval notation, (−3, ∞).
The domain of the function y = log(x + 3) is the set of all possible values that x can take without making the expression undefined.
For the logarithmic function y = log(x), the argument of the logarithm (x in this case) must be greater than zero, otherwise the result is undefined.
So, to find the domain of y = log(x + 3), we need to solve the inequality x + 3 > 0, which gives x > -3.
Thus, the function y = log(x + 3) is (−3, +∞), or in interval notation, (−3, ∞) is the answer.

Prove that if a^x=b^y=ab^xy then x+y=1
Answer:
Below.
Step-by-step explanation:
Prove that if
a^x = b^y = (ab)^(xy) then x + y = 1.
From the second equation:
y = 1 - x
So we have:
a^x = b^y = b^(1-x)
Taking logs:
x ln a = (1-x)ln b
x ln a + x ln b = ln b
x = ln b / ( ln a + ln b)
x = ln b / ln ab.
This is true if x + y = 1.
Now consider b^y = (ab)^(xy):
b^(1 - x) = (ab)^(x(1- x)
ln b - x ln b = x(1 - x)ln ab
ln b - x ln b = x ln ab - x^2 ln ab
Now we substitute for x = ln b / ln ab in this expression.
If left side = right side then we have proved this identity and therefore the original one.
Left side = ln b - (ln b / ln ab) * ln b = ln b - (ln b)^2 / ln ab.
Right side = (ln b / ln ab) * ln ab - [(ln b)^2 / (ln ab)^2] * ln ab
= ln b - (ln b)^2 / ln ab.
Left side = right side so this identity is true, and so the original one
( x + y = 1) is true also.

Answer:
y=[(x-6)/5]^(1/3)+4
Step-by-step explanation:
f(x)=5(x-4)^3 +6
trade x and y
x=5(y-4)^3 +6
x-6=5(y-4)^3
(x-6)/5=(y-4)^3
[(x-6)/5]^(1/3)=y-4

Step-by-step explanation:
If g(x) = 3, that means that the output is three.
Outputs are y values.
Look at the graph. When y=3, the x = 9.
So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9

contains some pencils and 11 pens. The
teacher uses a total of 182 pencils and pens.
Determine the number of pencils that are in
each box.
Answer:
26
Step-by-step explanation:
182 pencils devided by 7 identical boxes
182÷7
=26 pencils are in each box
Answer:
15 pencils in each box
Step-by-step explanation:
If each box has 11 pens,then there are 77 pens
In total 182 pencils and pens
182-77 = 105 (105 pencils)
105/7 = 15
15x7 = 105
11x7 = 77
105 +77 = 182
