Answer:
{3x+2}{x-1} = 3x²-x-2
Step-by-step explanation:
The given expression is :
{3x+2}{x-1}
We can solve it as follows :
{3x+2}{x-1} = 3x(x)+3x(-1) +2(x) +2(-1)
= 3x²-3x+2x-2
= 3x²-x-2
So, the expand form of the given expression is 3x²-x-2.

The point (4,-2) is the vertex of the graph of a quadratic function. The points (8,6) and (2,0) also fall on the graph of the function.
Part A:Complete the graph of this quadratic function by first finding two additional points on the graph.
Part B:What is the y-intercept of the graph?
Part C:What are the x-intercept?
Part D:Find the interval on which the rate of change is always positive.
Part E:What is the sign of the leading coefficient for this quadratic function? How do you know?
Answer:
Step-by-step explanation:
y = ax² + bx + c
~~~~~~~
(4, - 2), (8, 6), (2, 0)
a(4²) + b(4) + c = - 2
a(8²) + b(8) + c = 6
a(2²) + b(2) + c = 0
16a + 4b + c = - 2 .............. (1)
64a + 8b + c = 6 ............... (2)
4a + 2b + c = 0 ................. (3)
a = 0.5 ; b = - 4 ; c = 6
y = 0.5x² - 4x + 6
Part A: (0, 6), (6, 0)
Part B: (0,6)
Part C: (6, 0)
Part D: [ 4, ∞ )
The quadratic function has the form f(x) = ax² + bx + c, where a, b, and c are non-zero values, and the calculation of the values can be defined as follows:
Quadratic function:vertex point of graph function= (4,-2)
points= (8,6) and (2,0)
Using the formula of a quadratic function:
[tex]y = ax^2 + bx + c[/tex]
putting the value into the above-given formula:
[tex]\to (4, - 2), (8, 6), (2, 0)\\\\\to a(4^2) + b(4) + c = - 2\\\\\to 16 a + 4b + c = - 2.........................(a)\\\\\to a(8^2) + b(8) + c = 6\\\\\to 64a + 8b + c = 6......................................(b)\\\\\to a(2^2) + b(2) + c = 0\\\\\to 4a + 2b + c = 0................................(c)\\\\[/tex]
Computing the value of a,b, and c:
[tex]\to a = 0.5\\\\ \to b = - 4 \\\\ \to c = 6\\\\[/tex]
Putting the value of a, b, and c values into the quadratic function:
[tex]\to y = 0.5x^2 - 4x + 6[/tex]
So, the calculated points are:
Part A: (0,6)
Part B: (2,0) and (6,0)
Part C: x>4
Part D: positive the parabola upwards

If y varies directly as x, and y = 7 when x = 3, find y when x = 7
Answer:
AStep-by-step explanation:Direct variation, by definition, has the form shown below:
y=kx
Where k is the constant of proportionality.
Given the information in the problem, you can find k:
7=3k
k=7/3
Now you can find y when x=7 as following:
y=(7/3)x
Substitute values.
y=(7*7)/3
y=49/3

Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15
Answer:
80%
Step-by-step explanation:
0.75 ⇒ 100%
0.15 ⇒ x%
0.75x = 100·(0.15)
0.75x = 15
x = 15/(0.75)
x = 1500/75
x = 20%
100% - (discount) = x%
100% - (discount) = 20%
discount = 100%-20%
discount = 80%
Answer:
60% off

Ms. Cathy bought a package of pencils. Out of every 10 pencils, 8 are black. If there are 30 pencils in the pack, what fraction of the pencing in the pack are black?
What percent of the pencils in the pack are black?
What fraction of the pencils in the pack is black?
Answer:
Fraction: 24/30 Percentage: 80%
Step-by-step explanation:
It might want a simplified version of the fraction, so the answer for that one could be 4/5. I hope this helps :)
The percent of the pencils in the pack are black is,
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 24 / 30
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Ms. Cathy bought a package of pencils.
And, Out of every 10 pencils, 8 are black. .
Since, There are 30 pencils in the pack,
Hence, The percent of the pencils in the pack are black is,
⇒ 24 / 30 x 100
⇒ 2400 / 30
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 8 / 10 = x / 30
⇒ 240 = 10x
⇒ x = 24
Thus, The fraction of the pencils in the pack is black is,
⇒ 24 / 30
Thus, The percent of the pencils in the pack are black is,
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 24 / 30

Draw a model that shows 3 items being divided equally for 4 people. How much will each person have?
Answer:
Each person will get 3 pieces
Step-by-step explanation:
First you separate each item in 4 pieces. Then you get 12 pieces. Since 12 divided with 4 is 3, the answer is 3.
We want to draw a model that shows 3 items being divided equally for 4 people, we will see that each person receives 0.75 of an item.
Drawing the model.Here you just need to create an area that represents 3 elements, then replicate that area but this time with 4 sections, so we can see how much each of the 4 sections takes from the 3 elements.
The model can be seen below. (this is just an example, you should do it with a ruler to have a proper model).
Now to see how much each person haves we just take the quotient:
3/4 = 0.75
Each person receives 0.75 of an item.

A rectangular garden has a perimeter of 36 yards and a width of 8 yards.
What is the area of the garden?
72 square yards
80 square yards
100 square yards
112 square yards
Answer:
80 square yards
Step-by-step explanation:
We know we have a width of 8 yards and a perimeter of 36.
how I figured it out was:
36=(8*2) * (x*2)
8*2=16
36-16=10
So now we know the length and width.
area of a rectangle is lw (length * width)
10*8=80.

6.209 ____ 6.29
Answer:
it would be less than
Step-by-step explanation:
so it would be this <
The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given numbers,
6.209 and 6.29
Since, 6.209 - 6.29 = -0.081
Thus, 6.209 < 6.29.
Hence "The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29".
