Answer:

slope= -¾

y - intercept = 2 \frac{1}{4}

Step-by-step explanation:

3x +4y= 9

Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.

Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.

4y= -3x +9

For the coefficient of y to be 1, divide both sides of the equation by 4.

y =  -  \frac{3}{4} x +  \frac{9}{4}

y =  -  \frac{3}{4} x + 2 \frac{1}{4}

slope =  -  \frac{3}{4}

y - intercept = 2 \frac{1}{4}

A brick has a volume of 2,300 mL and a mass of 3.4 kg. what is the density of the brick
charle [14.2K]
The formula of a density is
p = M/V
where p is a density, M is a mass and V is a volume.
Given M = 3.4 kg and V = 2,300 mL or 2,300 cm<span>³, therefore
</span>p = 3.4 kg / 2,300 cm³ = 1.48 x 10⁻³ kg/cm³

The length of a rectangle is 3 times the width.the permitted of the rectangle is 72ft find the dimensions of the rectangle
ArbitrLikvidat [17]
Lets set up the relationship of the length to width:

l = 3w

Using this, we can make all the variables the same by substitution:

2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9

The width is 9, to the length must be 9*3, or 27.

Hope this helped!
