Answer:

y=-\frac{1}{3}x+7

Step-by-step explanation:

The slope-intercept form is: y=mx+b; where <em>m </em>is the slope, and <em>b </em>is the <em>y-axis </em>interception.

So, the problem is asking for a line that it's perpendicular to y=3x-5. This perpendicular relation means that the line we have to find have an inverse and opposite slope than the given line, that's expressed like this:

m_{1}m_{2}=-1

That expression is the condition to have perpendicular lines. So, the given line has a slope of 3, now we can find the slope of the new line:

m_{1}m_{2}=-1\\m_{1}=\frac{-1}{m_{2}}=-\frac{1}{3}

Now we have the slope of the new perpendicular line, we use the point-slope formula to find its equation:

y-y_{1}=m(x-x_{1})\\ y-7=-\frac{1}{3}(x-0)\\y=-\frac{1}{3}x+7

Therefore, the slope-intercept form of the new perpendicular line is:

y=-\frac{1}{3}x+7

How you solve this ?
jonny [76]
You have to use Pythagorean theorem

12^2+20^2 = x^2

sqrt(144*400) = x^2
sqrt(544) = x

X = 4  sqrt(34)

7. The following clues are given about a bucket of bubble gum.
scZoUnD [109]

There were 472 pieces of bubble gum in the bucket

Step-by-step explanation:

The following clues are given about a bucket of bubble gum

1. There are between 400 - 500 pieces of gum in the bucket

2. The bubble gum was purchased in 4 equally-sized bags

3. The product of all the digits is 56

Let us explain how to solve the problem

∵ The number of the pieces of gum is between 400 and 500

∴ The number of pieces is 3-digit number and its hundred digit is 4

∵ The product of all digits is 56

∵ One of the digit is 4

∵ 56 ÷ 4 = 14

∴ The product of the ten digit and the one digit is 14

∵ 14 = 2 × 7

∴ The ten digit and the one digit are 2 and 7 or 7 and 2

- If the ten digit is 2 and the one digit is 7

∴ The number of pieces is 427

∵ The bubble gum was purchased in 4 equally-sized bags

- That means there were 4 pieces of bubble gum in each bag

∴ The number of pieces must divisible by 4

- The number is divisible by 4 if it is an even number and the number

 formed from the ten digit and one digit is divisible by 4

∵ 427 is an odd number

∴ 427 not divisible by 4

- If the ten digit is 7 and the one digit is 2

∴ The number of pieces is 472

∵ 472 is an even number

∵ 72 divisible by 4

∴ 472 is divisible by 4

∴ There are 472 pieces of gum in the bucket

There were 472 pieces of bubble gum in the bucket
