Answer: -2x(5y+6)
Step-by-step explanation:
If x and y vary directly, and x = 12 when
y = 4, what is the value of x when y = 1 ?
Answer:
3
Step-by-step explanation:
Answer: x = 3
Step-by-step explanation:
y for x
4 for 12
1 for ?
Cross multiply
4? = 12 x 1
4? = 12
Divide both sides by 4
? = 3
When y = 1, x = 3.

Hey! I need some help with this question I'm not very good with math so if anyone would be willing to help me out id be grateful thx.
An asteroid is 10^{8} miles away from earth, and it is traveling at a speed of 10^{5} miles per day.
How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
1,000 is equal to 10^3

The m
Write in slope intercept: slope=2/3 y-intercept =-1
Answer:
y=2/3-1.
Step-by-step explanation:
Slope intercept is the easiest out of the forms because you just plug in what is given. Here you are given 2/3 for the slope and the y-int Is -1.
The formula for slope intercept is y=mx+b
m= slope
b= y-int
And you just plug it in.
so the answer would be: y=2/3-1. Hope this helps!
2) divide 54kg in the ratio 1:5=
Answer:
9:45
Step-by-step explanation:
1:5= 6 parts
54/6=9
9*1=9
9*5=45
9:45
Answer:
9kg and 45kg
Step-by-step explanation:
In fraction from 1:5 is equivalent to 1/(1+5) = 1/6 and 5/(1+5) = 5/6.
So the answer is 54 * 1/6 and 54 * 5/6.
= 9 and 45.

What is the image of (2, 1) after a dilation by a scale factor of 4 centered at the
origin?
HELP
Answer:
The image of the point is (8, 4)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)
Let us solve the question
∵ The point is (2, 1)
∴ x = 2 and y = 1
∵ The point dilated by a scale factor of 4 centered at the origin
∴ k = 4
→ By using the rule above multiply each coordinate of the point by 4
∵ The image of the point is (kx, ky)
∵ kx = 4 × 2
∴ kx = 8
∵ ky = 4 × 1
∴ ky = 4
∴ The image of the point is (8, 4)

if AB= 5 what is the exact length of BD in square ABCD
Answer:
sqrt 50
Step-by-step explanation:
First of all this is a square so if AB = 5, then AD is also 5.
Let's get rid of the other triangle and only focus on triangle ABD.
Using Pythagorean theorem we are able to solve this problem.
The Pythagorean Theorem basically states that:
a^2 + b^2 = c^2
Where a and b are the legs and c is the hypotenuse, aka the thing that we are trying to solve for right now.
Substitute these numbers in: 5^2 + 5+2 = c^2
Solve: 50 = c^2
c= sqrt 50
^ and that is our answer!
