Nathan and his children went into a grocery store and he bought $12 worth of apples and bananas. Each apple costs $1.50 and each banana costs $0.60. He bought a total of 11 apples and bananas altogether. By following the steps below, determine the number of apples, x,x, and the number of bananas, y,y, that Nathan bought.
Determine three ways to have a total of 11 apples and bananas:
Step-by-step explanation:
X= apple y=banana 1 apple cost $1.50 and a1 banana cost $0.60 nathan buy 11banana and apple 1.50×11 = 16.5 0.60×11= 6.6. 16.5 +6.6 =23.1

Answer:
4, 7, 9, 12, 18, 32
Step-by-step explanation:
The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers. I hope this helps you out :)

Answer:
The slope is -1/2
Answer:
-(1/2) or -0.5
Step-by-step explanation:
select two coordinates. for example, (2,2) and (4,1).
do (y2 - y1) ÷ (x2 - x1).
in this case, (1 - 2) ÷ (4 - 2). you should end up with -(1/2), or -0.5
Identify the solution set 2(-x -9) = -2x + 8
A) infinitely many solutions
B) Only one solution

D) impossible
Answer:
D) impossible
Step-by-step explanation:
y = (x2 - 2x + 1)
y = (x - 1)(x - 1)
Prove that the following functions are equivalent through algebraic and numerical proof
Answer:
see below
Step-by-step explanation:
y = (x² - 2x + 1)
y = (x - 1)(x - 1)
First, recognize that the first equation is fully simplified/expanded already.
Now, we should solve for the second equation.
FOIL the expressions: first–outer–inner–last
(x - 1)(x - 1)
F: x²
O: -x
I: -x
L: 1
Combine these terms.
x² - x - x + 1
x² - 2x + 1
Notice that this equation is identical to our first equation. Therefore, the functions are equivalent.
Hope this helps!
y = (x^2 - 2x + 1)
y = (x - 1)(x - 1)
Algebraic Proof
FOIL y = (x - 1)(x - 1)
y = (x - 1) (x -1 ) = x^2 -2x + 1
Done.
Numeric Proof
Let x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = 2 + 2
y = 0
Let x be 1 again.
y = (x - 1)(x - 1)
y = (1 - 1)(1 - 1)
y = 0
There you have it. Both equations are the same.

The amount y (in dollars) that you earn by working x hours is represented by the equation y = 9x. A) What is the slope? B) What does the slope mean? Interpret! C) How much money would you make if you worked 40 hours?
Answer:
360 dollars
Step-by-step explanation:
Equation;
y = 9x
A) What is the slope?
The slope in an equation is the coefficient of the x variable. In this question, the slope is 9.
B) What does the slope mean? Interpret!
The slope shows the relationship between the x and y values.
This means that for every single unit change of x, y changes by 9 times.
C) How much money would you make if you worked 40 hours?
x = working hours
y = Amount
y = 9 (40) = 360 dollars

The wholesale price for a dozen pairs of socks is $4.30. The retail price for the same dozen pairs of socks is $9.25. What is the mark-up the retailer used? Write your answer as a complete sentence.
Answer:
the mark up used by the retailer is 115.12% of the wholesale price
Step-by-step explanation:
Mark-up is the percentage increase of the retail price over the wholesale price
Mark-up = (difference between retail and whole sale price / retail price ) x 100
difference between retail and whole sale price = $9.25 - $4.30 = $4.95
(4.95 / 4.3) x 100 = 115.12%.
What is n in the equation? 16 = 8 n
Answer:
n = 2
Step-by-step explanation:
16 = 8n
divide by 2 on both sides
2 = n
n equals 2
Answer: n = 2
Step-by-step explanation:
Switch sides:
8n =16
Divide both sides by 8:
8n/8 = 16/8
Simplify:
n =2
1. a circle has a circumfrance 88cm find its radius
2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest
Step-by-step explanation:
Number 1
Circumference = 88cm
Circumference = 2πr
2πr = 88
πr = 88/2
πr = 44
22r/7 = 44
22r = (44 × 7)
r = (44 × 7)/22
r = 2 × 7
r = 14cm
Number 2
Length of arc = 44cm
Angle = 45°
L = ∅/360 × 2πr
44 = 45/360 × 2πr
44 = ⅛ × 2πr
44 = ¼ × πr
πr = 44 × 4
22r/7 = (44 × 4)
22r = (44 × 4 × 7)
r = (44 × 4 × 7)/22
r = 2 × 4 × 7
r = 2 × 28
r = 56cm
Perimeter = L + 2r
P = 44cm + 2(56cm)
P = 44cm + 112cm
P = 156cm

Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utility, use it to graph the function and verify the real zeros and the given function value.
n=3
4 and 4i are zeros;
f(-1)=85
F(x) = ________
Givem that at n = 3: 4 and 4i are zero;
Then;
[tex](x - 4)(x - 4i)(x + 4i) \: (x - 4)( {x}^{2} - ( {4i)}^{2} \\ (x - 4)(x - 4i)(x + 4i) \: (x - 4)( {x}^{2} + 16) \\ (x - 4)(x - 4i)(x + 4i) \: {x}^{3} + 16x - {4x}^{2} - 64 \\ (x - 4)(x - 4i)(x + 4i) \: {x}^{3} - {4x}^{2} + 16x - 64[/tex]
Hence the function is:
