11) -6x – 9y = 0
-24x = 36y
Answer:
x = 0, y = 0
or
(0, 0)
Step-by-step explanation:
-24x - 36y = 0
divide the equation by 4
-8x - 9y = 0
-6x - 9y = 0
multiply the second equation by -1
6x + 9y = 0
add them together
-8x - 9y = 0
6x + 9y = 0
-2x = 0
x = 0
substitute into the second equation
-8 * 0 - 9y = 0
-9y = 0
y = 0
Write an equation of a line that would be parallel to y = 5x -9
Answer:
x/5+9/5=y or x+9/5=y
Step-by-step explanation:
y= 5x-9
x=5y-9
x+9=5y
x+9/5=y
Find the value of X in this proportion.
- 27/4
- 18
- 9/8
- 9/2
Answer:
the answer is 9/2
Step-by-step explanation:
So you have (x+3)/6=5/4
Cross multiply and it will turn to this
4(x+3)=6×5 which is 30
= 4x+12=30
4x=30-12
4x=18
Divide both sides by 4 to make x subject of the formula
then your answer is 9/2

Jace ordered a banner in the shape of a parallelogram from a print shop. A parallelogram is shown. The length of the sides are 9 feet, and the length of the top and bottom sides are 12 feet. A diagonal is drawn from one point to the opposite side. The length of the diagonal is 19 feet. Heron's formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot The print shop charges $1.10 per square foot for banners of any shape and size. What is the approximate cost of the banner before tax? $41.95 $46.14 $83.90 $92.30
Answer:
92.30
Step-by-step explanation:
The area of the banner is the amount of space on it
The approximate cost of the banner is $92.30
The dimension of the banner is given as:
Length = 9 feet
Width = 12 feet
Diagonal = 19 feet
The figure of the banner is not given.
However, the area of the banner from the complete question is 83.90
Given that the unit cost is $1.10, the total cost would be:
Total = 1.10 * 83.90
Evaluate the product
Total = 92.29
Approximate
Total = 92.30
Hence, the approximate cost of the banner is $92.30

Answer:
B, 4
Step-by-step explanation:
To do this you can use the Pathagaryos thereom a^2+b^2=c^2
So we have (x-2)^2+x^2=20
We can expand (x-2)^2 and get
x^2-4x+4
so we have x^2 -4x +4 + x^2=20
We can combine like terms and subtract 20 from both sides to get
2x^2-4x-16=0
We can factor this and get (2x+4)(x-4)
which means that x=4 and -2
Obviously the length can't be a negative and so we reject x= -2 and we get x=4
We can double check it and see that
(4-2)^2+4^2=20
and it does

A colony of amoebas is being studied. The mass of the colony triples every day. On Day x of the study, the colony has a mass of 3 ^ x mg. a. What is the mass of the colony on Days 3, 2 and 1? What is the mass of the colony on Day 0, when the study begins? Show your work .
Answer:
mass on day 1: 3
mass on day 2: 9
mass on day 3: 27
Step-by-step explanation:
using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)
3^1 = 3
3^2 = 9

k-3k²-3k+2k²
what is the answer
please help me
Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k

Clark Kent and Lois Lane were laying on a blanket, enjoying a relaxing picnic when Clark noticed a giant asteroid approaching Earth. Clark calculates the angle of elevation of the asteroid's approach to be 62°. Lois' penthouse apartment is also in the pathway of the asteroid's approach, 100 feet above ground. Clark's eye is 75 feet from the base of Lois' building. Will the asteroid take out Lois' penthouse apartment?
Answer:
The asteroid will not take out Lois' penthouse.
Step-by-step explanation:
Since the distance between Clark and the base of Lois' building is x = 75 feet and the asteroid is at an angle of elevation of Ф = 62°. These two components form a right-angled triangle with opposite side h which is the height of the asteroid above the ground.
So, by trigonometric ratios,
tanФ = h/x
h = xtanФ
h = 75 ft × tan62°
h = 75 ft × 1.8807
h = 141.1 feet
Since h = height of asteroid above the ground = 141.1 feet is greater than height of the penthouse above the ground = 100 feet, the asteroid will not take out Lois' penthouse.

Move the numbers to the blanks to order them from least to greatest value.
|-2|
9/8
0.4
-0.89
1/2
Answer:
This is from least to greatest.
-0.89, 0.4, 1/2, 9/8, (-2)
Step-by-step explanation:
-0.89 is negative so it is the least because the other numbers are positive.
0.4 is next because 0.4 is smaller than 0.5 because 1/2 = 0.5
Then 1/2 because 9/8 is more than 1/2 of 8 which would be 4, but 9/8 is bigger than 4/8.
Finally the biggest number is (-2) Because the absolute value of -2 is 2, and 2 is a whole number, which is bigger than the decimals and fractions.
And of course 9/8 is equal to 1 1/8 but 2 is bigger than 1 1/8

Find the slope of the line y = 7x – 2.
Answer:
m = 7, b = -2
Step-by-step explanation:
The equation y = 7x - 2 is written in y = mx + b, also known as slope intercept.
In slope-intercept, m is the slope and b is the y-intercept.
m = coefficient of x
b = constant
Similarly,
m = 7
b = -2
Hence, m = 7 and b = -2.
