which of the lines graphed has a slope of -2 and a y-intercept of 3
Answer:
I think b
Step-by-step explanation:
need a better quality photo
Answer:
B
Step-by-step explanation:
It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

Pairs of shoes are manufactured for $24. They are sold to a warehouse with a mark-up of 15%. The warehouse sells the shoes to a distributor after charging a holding fee of $10 per pair. The distributor sells them to ‘Fine Shoes’ for a percentage profit of 12%. The store then marks them up by 30%.
a. Determine the price of a pair of shoes if you buy it from one of the ‘Fine Shoes’ stores (round to the nearest 5 cents). Show working out.
Answer: $54.75
Step-by-step explanation:
The price the shoes are sold to the warehouse is:
= 24 * ( 1 + 15%)
= 24 * 1.15
= $27.60
The price the warehouse sells it is:
= 27.60 + 10
= $37.60
Price distributor sells is:
= 37.60 * 1.12
= $42.112
Fine shoes will then sell at 30% profit:
= 42.112 * 1.3
= $54.7456
= $54.75
Help sir! Thank you, Mr Thompson
Problem 1
To find the y intercept, plug in x = 0 and simplify
f(x) = (x-2)(x+4)
f(0) = (0-2)(0+4)
f(0) = (-2)*(4)
f(0) = -8
We have x = 0 pair up with y = -8
The y intercept is (0,-8)
Answer: Choice D
========================================
Problem 2
(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.
The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.
Answer: C) Parabola opens upward
========================================
Problem 3
Answers:
A = h(x)B = f(x)C = g(x)Explanation:
Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).
Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.
The volume of a cube related to the area of a face by the formula V =A^3/2. What is the volume of a cube whose face has an area of 25mm^2.
Answer:
Volume = 125 mm^3
Step-by-step explanation:
Here, we want to get the volume of the cube
What we have to do here is to substitute the value of the area
We have this as
:
V = 25^(3/2)
V = (√25)^3
V = 5 * 5 * 5 = 125 mm^3

you just do 5 * 6 to get 30 and since there isn't anything under the 6, you put an imaginary 1 to get you 7 so your answer will be 30/7

The LCD PLEASEEEE
EEEEE
Answer:
-2
Step-by-step explanation:
(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4
lcm is 6
(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4
(x + 2) × 3 + ( x + 4) × 2 = 4
3x + 6 + 2x + 8 = 4
correct like terms
3x + 2x + 6 + 8 = 4
5x + 14 = 4
5x + 14 - 14 = 4 - 14
5x = - 10
5x ÷ 5 = -10 ÷ 5
x = -2

Answer:
3 3/5
Step-by-step explanation:
Answer:
Your answer would be 3.6, or 3 3/5
Step-by-step explanation:
We need to isolate x, so start by subtracting 50 from both sides: 450 = 125x
Next, divide each side by 125:
3.6 = x, or x = 3 3/5

Your mother is 25 years older than you. Your father is 3 years older than your mother. The product of all three ages are 32,130. How old is your father?
Explanation would be appreciated!
My father is 42 years old as obtained from the cubic polynomial's real root.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
let my age be x years.
So, My mother is (x + 25) and my father is (x + 28) years.
∴ {x(x + 25)(x + 28) = 32130.
(x² + 25x)(x + 28) = 32130.
x³ + 53x² + 700x = 32130.
x³ + 53x² + 700x - 32130 = 0.
Now solving this has only one real solution x = 17.
So, My father is (17 + 25) = 42 years old.

Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2
