Answer:

Step-by-step explanation:

y=-2x

x y

0 0

1 -2

2 -4

3 -6

4 -8

or if it's just y=-2 then it's just a horizontal line going through -2 on the y axis

but it's a table so i'm assuming there's another variable that would indicate the usage of a table

What is the slope and y intercept of X=-13/2 - 2/7y

Zigmanuir [339]

Answer:

Slope = -7/2

y intercept = -91/4

Step-by-step explanation:

Given the line

x = $\frac{-13}{2}$ - $\frac{2}{7}$ y

We know that in the equation y = mx + c, m is slope and c is y intercept,

So bring the given equation to above form,

x = $\frac{-13}{2}$ - $\frac{2}{7}$ y

x = $\frac{-91-4y}{14}$

14x = -91 -4y

4y = -14x-91

y = $\frac{-14x}{4}$ $\frac{-91}{4}$

comparing above equation with y= mx+c

slope, m = $\frac{-14}{4}$ = $\frac{-7}{2}$

y intercept, c = $\frac{-91}{4}$

A spinner is divided into 10 congruent sections.Each section is labeled with a number as shown.What is the probability that the

Rufina [12.5K]

Answer:

50%

Step-by-step explanation:

The only numbers that are multiples of 2 are all even numbers. From 1 to 10 there are a total of 5 even numbers, meaning that only 5 sections are multiples of 2. Therefore, the probability of the arrow landing in a section that is labeled with a number that is a multiple of 2 would be

5/10 if we simplify this it would be 1/2 or 50%

Finally, we can say that the probability of the arrow landing on one of these sections is 50%

Geometry help PLZ!!!

alisha [4.7K]

Answer:

Step-by-step explanation:

The similar triangles are shown in the attached photo.

Triangle ABC is similar to triangle XZY. Therefore,

AB/XZ = BC/ZY = AC/XY

From the dimensions given,

(x-8)/45 = (2x - 8)/24

Cross multiplying,

24(x-8) = 45(2x - 8)

24x - 192 = 90x - 360

Collecting like terms and making the terms containing the variable, x be on the left hand side and the constants be on the right hand side,

24x - 90x = -360+92

-66x = -268

x = 268/66

x = 4.06

x = 4

(10 points)I REALLY NEED HELP NOW!! (A) positive (b)negative (c)zero

tatyana61 [14]

Hello from MrBillDoesMath!

Answer:

Cchoice B is the correct answer.

Discussion:

As stated by an earlier respondent, choice B is the correct answer. But why?

From the diagram, point B lies between 0 and 1 which means B is positive

From the diagram, point C lies between -1 and -2 which means C is negative

The quotient of a negative number by a positive number is negative, giving the answer as choice c

Regards,

MrB

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

if anyone can solve this gets a $10 gamestop card i already got the codeSolve for x. Show each step of the solution. 2.5(10 - x)

schepotkina [342]

Remark

Forget the Gamestop. I'd never use it. This one is on the house.

Solution

2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12) The first step is to remove the brackets. Be very careful you understand the bracket on the right.

25 - 2.5x + 10 = 72 - 7.5x - 18 Study the signs carefully. Collect like terms.

35 - 2.5x = 54 - 7.5x Add 7.5x to both sides.

35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x

35 + 5x = 54 Subtract 35 from both sides.

5x = 19 Divide by 5

x = 19/5

x = 3 4/5 = 3.8

Check

When you numbers are so cumbersome, you should check the answer.

LHS

2.5(10 - 3.8) + 10

2.5(6.2) + 10

15.5 + 10

25.5

RHS

72 - 1.5(5*3.8 +12)

72 - 1.5(19 + 12)

72 - 1.5(31)

72 - 46.5

25.5

RHS = LHS The solution checks.
