write an equation in slope-intercept form of the line that passes through the given point and given slope, (-5,-3);slope =-3/5

arsen [322]

Answer:

y= $\frac{-3}{5}x-6$

Step-by-step explanation:

Hi there!

We are given the point (-5, -3), and a slope of -3/5

We want to write the equation of the line in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope, and b is the y intercept

As we are already given the slope, we can immediately plug it into the equation

y= $\frac{-3}{5}x$ +b

We need to find b, though

We can use (-5, -3) to help us, as the equation will pass through that line

Substitute the value of x as -5 and the value of y as -3 to solve for b

-3= $\frac{-3}{5}*-5+b$

Now, on the right, multiply -3/5 and 5 together

-3=3+b

Subtract 3 from both sides

-6=b

Substitute 6 as b in the equation

y= $\frac{-3}{5}x$ -6

Hope this helps!

The sum of two numbers is 724. one of the numbers is 217. what is the other number?

Anni [7]

Answer:

507

Step-by-step explanation:

For the Algebraic Expression,

let the two numbers be X and y

lets assume x = 217

From the question,

217 + y = 724

y = 724-217

y = 507

Therefore, the other number is 507

A cylindrical hole is drilled into a piece of wood. The radius of the hole is 8 millimeters less than the height, x, of the hole

ipn [44]

Using the solver function of the calculator, we can find the roots of the polynomial.

x1 = 9.72484

x2 = −5.36242+8.74882i

x3 = −5.36242−8.74882i

<span> Since dimension cannot be imaginary, therefore the height of the cylindrical hole is 9.72 mm. Calculating for radius r: r = 9.72 mm – 8 mm r = 1.72 mm The volume of cylinder is given as: V = π r^2 h V = π (1.72)^2 (9.72) <span>V = 90.34 mm^3</span></span>
