Answer:

3x - 2y = 10

Step-by-step explanation:

We are given that the sum of two numbers is 0 and twice the smaller number subtracted from 3 times the larger number is 10.

Assuming x to be the large number and y to be the smaller number we can write an equation to represent this.

Sum of two numbers is 0:

$x+y=0$

Twice the smaller number subtracted from 3 times the larger number is 10:

$3x-2y=10$

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

cestrela7 [59]

Let 's x the width of the sidewalk.

Area of the swimming pool= 10*16=160 (ft²)
Area of the sideway+the swimming pool= (16+2x)*(10+2x) =160+155

==>160+20x+32x+4x²=160+155
==>4x²+52x-155=0
Δ=52²+4*4*155=5184=72²
==>x=(-52+72)/2=5/2 or x=a negative to exclude.

Width of the sideway=5/2 ft

Answer:

$y = \frac{4}{3}x - 13$

Step-by-step explanation:

The equation for a line in slope-intercept form is $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept. This means that the slope of $y = \frac{4}{3}x + 5$ is 4/3.

We would like to find a line parallel to $y = \frac{4}{3}x + 5$ which passes through the point (12, 3). Any parallel line must have the same slope, so the equation for the new line will be $y = \frac{4}{3}x + b$ for some number $b$ . We know that $y$ must be equal to 3 when $x$ is equal to 12, so 3 = (4/3)(12) + b. This means that 3 = 16 + b, so b = -13.

Therefore, the equation for the parallel line is $y = \frac{4}{3}x - 13$ .
