Y=-3/5x-46/5 or y=-3/5x-9 1/5
Orlov [11]3 years ago

Answer:

y= -3/5x - 46/5

Step-by-step explanation:

Since the line is perpendicular to y=5/3x-5, We can find the gradient since perpendicular lines have negative reciprocal gradients of each other, so in this case the gradient of the line is -3/5. We have a point, we have the gradient, so we can substitute in y=mx+c to find the y-intercept c, so -5 = (-3/5)(-7) + c.

Calculating will give c= -46/5

so the equation is y= (-3/5)x + (-46/5)

How do you determine where to place the decimal point in the product?
frez [133]

Let's look at an example:

2.24 x 21.6

2.24\\ 21.6\\ ______

Do normal multiplication and get

48384   This is not correct, until we put the decimals in. To know how to do this, count the number of decimal spaces from the factors. In 2.24, there are 2, because .24. In 21.6 there are 1 because of .6. This mean three places, so 48384 becomes

48.384

I need help plz.
viva [34]

Answer:

slope = \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

m = \frac{6-0}{4+8} = \frac{6}{12} = \frac{1}{2}

A room has an area of 60 square meters and a perimeter of 32 meters. What are the length and width of the room?
Dominik [7]

Answer:

6 and 10

Step-by-step explanation:

xy=60

2(x+y)=32

x+y=16

y=16-x

Substitute y into area equation

x(16-x)=60

16x-x^2=60

x^2-16x+60=0

(x-10)(x-6)=0

x=10, 6

y=6, 10
