someone help please

Answer:

y = -2x

Step-by-step explanation

slope intercept form: y = mx + b

m is slope and b is y-intercept

1. lets find y-intercept cuz thats easiest

the line crosses (0,0) at the y-axis so there is no y-intercept

2. to find slope rise/run

we'll start at (0,0) since that's the y-intercept

3. slope is rise/run = -2/1 = -2

it's negative becuase it's going left

_____________________________________________________

another way you can find slope is by the equation y2 - y1/ x2 - x1

take 2 random points from the line, i will use (0,0) and (-2,4)

4 - 0/ -2 - 0 = 4/-2 = -2

slope is -2

Step-by-step explanation:

Answer:

(-2, 3)

Step-by-step explanation:

the point B is

B(x,y)

x

AB (A to B) is twice BC ( B to C )

AB is 2 - x. BC is x - (-4)= x + 4

So

2-x=2 (x + 4)

2-x=2x + 8

3x = -6

x = -2

y

(Same logic as above)

AB is -5 -y. BC is u - 7

-5 -y = 2(y - 7)

-5 - y = 2y - 14

3y = 9

y= 3

the point is (-2, 3)

Answer:

5.6

Step-by-step explanation:

EC = 10

BC = 14

14/10 = 1.4

DE = 4

AB = x = 1.4 * 4 = 5.6

Answer:

[tex]\frac{x}{14} = \frac{4}{10}[/tex]  (set up as a proportion)

10x= 56 (cross multiply and then solve)

x= 5.6

Answer:

10.53%

Step-by-step explanation:

The first step is to divide 2 by 19 to get the answer in decimal form: 2 / 19 = 0.1053 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.1053 * 100 = 10.53%

Answer:

11%

Step-by-step explanation:

Divide 2 by 19 and then move the decimal place twice to the right. It should be 10.5 but if rounded it becomes 11 so 11%

4th answer

Step-by-step explanation:

Answer:

m = 2

Step-by-step explanation:

The given equation is :

8x – 4y - 9 = 0

The general equation of a line is given by :

y = mx+b ...(1)

here m is slope and b is y-intercept

Equation (1) can be written as :

8x – 4y = 9

Dividing both sides by (-4)

[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)

Comparing equation (1) and (2), we get :

m = 2

Hence, the slope of the line is 2.

hey mate I don't know it's answer

Step-by-step explanation:

sorry!

do your homework at your own

Answer:

hope ithelps :)

Step-by-step explanation:

1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.

And horizontal lines go through the y-axis and have equations of y= a #

2)the point on the vertical line is (4,-5), it has a y-value of -5

****Every y value on a horizontal line will be the same

so the equation for a perpendicular line would be y= -5

Answer:

57.6

Step-by-step explanation:

48% is the same as 0.48

so 120 * 0.48 = 57.6

Answer:

Multiply the second equation by -3 to get -3x - 9y = -30.

Step-by-step explanation:

When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.

In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.

3x + 5y = 30

-3x - 9y = -30

3x + 5y -3x - 9y = 30 + (-30)

0 - 4y = 30 - 30

-4y = 0

You can find y and then x later on from here.

Answer:

t=16

Step-by-step explanation:

you have to change the numbers to get just the variable.

we start from -3.

8=t/2

(we multiply by 2 instead of dividing)

8×2=16

t=16

Answer:

1.08 * 10^57

Step-by-step explanation:

Given that:

Number of atoms in the sun = 1.2 * 10^57

Number of atoms in the rest of the solar system = 1.2 * 10^56

About how many more atoms exist in the Sun than in the rest of the Solar System?

Subtract the number of atoms in solar system from number of atoms in sun

(Number of atoms in sun - number of atoms in rest of the solar system)

(1.2 * 10^57) - (1.2 * 10^56)

= 1.08 * 10^57 (using calculator)

Answer:

  (a), (b), (c) are non-proportional

  (d) is proportional

Step-by-step explanation:

An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).

The table of (d) is proportional, with a constant of proportionality of 6.5.

Comment on (c)

In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.

Answer:

(2 n)/3-2/3 = n/6+4/3

(2 n)/3-2/3 = (2 n-2)/3:

(2 n-2)/3 = n/6+4/3

Put each term in n/6+4/3 over the common denominator 6: n/6+4/3  =  n/6+8/6:

(2 n-2)/3 = n/6+8/6

n/6+8/6 = (n+8)/6:

(2 n-2)/3 = (n+8)/6

Multiply both sides by 6:

(6 (2 n-2))/3 = (6 (n+8))/6

6/3 = (3×2)/3 = 2:

2 (2 n-2) = (6 (n+8))/6

(6 (n+8))/6 = 6/6×(n+8) = n+8:

2 (2 n-2) = n+8

Expand out terms of the left hand side:

4 n-4 = n+8

Subtract n from both sides:

(4 n-n)-4 = (n-n)+8

4 n-n = 3 n:

3 n-4 = (n-n)+8

n-n = 0:

3 n-4 = 8

Add 4 to both sides:

3 n+(4-4) = 8+4

4-4 = 0:

3 n = 8+4

8+4 = 12:

3 n = 12

Divide both sides of 3 n = 12 by 3:

(3 n)/3 = 12/3

3/3 = 1:

n = 12/3

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Answer:

d

Step-by-step explanation:

The solution to the equation given as 2x - 3 = 3 is  x = 3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The equation is given as

2x - 3 = 3

The above equation is a linear function

So, we plot a linear equation (see attachment)

On the attached graph, we can see that the solution is a vertical line that passes through x = 3

Hence, the solution to the equation given as 2x - 3 = 3 is  x = 3
