x(x-7)=0
x=0 or 7
Answer:
x=0 x=7
Step-by-step explanation:
x^2 -3x = 4x
Subtract 4x from each side
x^2 -3x-4x=0
x^2 -7x = 0
Factor out an x
x(x-7) =0
Using the zero product property
x=0 x-7 =0

The Coffee Counter charges $11
per pound for Kenyan French Roast coffee and $10
per pound for Sumatran coffee.
How much of each type should be used to make a 20 pound blend that sells for $10.60
per pound?
Answers
Answer:
12 pounds of Kenyan French Roast coffee
8 pounds of Sumatran coffee
Step-by-step explanation:
if you use x pounds of Kenyan French Roast coffee and y pounds of Sumatran coffee then you know that
11x + 10y = 10.6 * 20
x+y=20
10x+10y=200
11x+10y=212
x=12
y = 20-x = 20-12 = 8
so you want to use
12 pounds of Kenyan French Roast coffee
8 pounds of Sumatran coffee

STEM The diagram shows the structure of a molecule of sulfur dioxide. The ratio of oxygen atoms to sulfur atoms in sulfur dioxide is always the same. How many oxygen atoms (O) are there when there are 6 sulfur atoms (S)? Explain how you got your answer.
Answers
The ratios of oxygen atom and sulfur atom is an illustration of equivalent ratios.
There are 12 oxygen atoms, when the number of sulfur atom is 6.
From the diagram, we have:
[tex]S = 1[/tex]
[tex]O_x = 2[/tex]
So, the ratio is:
[tex]S : O_x = 1 : 2[/tex]
When there are 6 sulfur atoms, the equation becomes
[tex]6 : O_x = 1 : 2[/tex]
Express as a fraction
[tex]\frac{O_x}{6}= \frac{2}{1}[/tex]
Multiply both sides by 6
[tex]O_x = 2 \times 6[/tex]
[tex]O_x =12[/tex]
Hence, there are 12 oxygen atoms

Answer:
x = -7
Step-by-step explanation:
y = (x+7)^2 -3
This is in vertex form
y =a(x-h)^2+k where (h,k) is the vertex and the line of symmetry for a vertical parabola is x=h
y = (x- -7)^2 -3

If 4x – 5 = 96, what is the value of 4x + 12?
Answers
Answer:
113
Step-by-step explanation:
Solving the first equation, 4x - 5 = 96, we get x = 25.25:
4x - 5 = 96
add 5 to both sides
4x = 101
divide both sides by 4
x = 25.25
Then we plug that into 4x + 12.
We already know 4x = 101, so 101 + 12 = 113
The value of the expression will be equal to 113.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Solving the first equation, 4x - 5 = 96, we get x = 25.25:
4x - 5 = 96
Add 5 to both sides.
4x = 101
Divide both sides by 4.
x = 25.25
Then we plug that into 4x + 12.
4x = 101,
Substitute the value of 4x into the expression.
101 + 12 = 113
Therefore, the value of the expression will be equal to 113.

Mr lim had just enough money to buy 6 similar lamps. However, he bought 3 such lamps and had $950 left. How much money did mr lim have at first?
Answers
Let the cost of a lamp = x
6 lamps would cost 6x
He bought 3 lamps at 3x plus Thad 950 left.
3 lamps plus the 950
Would be the same amount as 6 lamps:
Set up an equation and solve for x:
3x + 950 = 6x
Subtract 3x from both sides:
950 = 3x
Divide both sides by 3:
X = 316.67
Each lamp was $316.67
Multiply the price of a lamp by 6:
316.67 x 6 = 1900
He had $1900
Answer: $1900
Step-by-step explanation:
Mr Lim had enough money to buy 6 similar lamps. However he only bought 3 such lamps. That means he had only spent half of his money (6-3=3).
So, if he take money remaining with him = x = $950
Amount of money he first had = 2x =$950×2 = $1900

Question 5
Part A
if Sin(x) = - 3/5 and tan(x) < 0
you are told 3 things
cos(x) must be plus because there are 4 quads. Everybody is plus in quad 1. Sin and tan are <0 so you must be in quad 4 where cos(x) => 0From sin^2(x) + cos^2(x) = 1, we get that cos(x) = 4/5Tan(x) = sin(x) / cos(x)tan(x) = Sin(x)/cos(x)
tan(x) = -3/5 // 4/5
Tan(x) = -3/4
Part B
cos(2x) = cos^2(x) - sin^2(x)
cos(2x) = (4/5)^2 - (-3/5)^2
cos(2x) = 16/25 - 9/25
cos(2x) = 7/25

x + y = 90
sin(x +y) = 1
