What are the slope and y-intercept of y + x?

Mathematics
1 answer:
Vesnalui [34]2 years ago
4 0

Answer: m=-1; b=0

Step-by-step explanation:

I am assuming the equation is y+x=0. In this case, change it to y=mx+b to get y=-x.

This shows that the slope is -1, and there is no y intercept.

Which equation represents the graphed function?
scoundrel [369]

Solution:

we have been asked to find

Which equation represents the graphed function?

As we can see in the graph, the line is passing through the point (2,0) and (0,-3).

As we know the equation of the passing through two points is given by the formula

(y-y_1)=m(x-x_1)\\
\\
m=slope=\frac{y_2-y_1}{x_2-x_1}=\frac{-3-0}{0-2}=\frac{3}{2}  \\

So the equation of the line will be

y-0=\frac{3}{2}(x-2)\\
\\
y= \frac{3}{2}x-3\\
\\

The second on a watch is 14mm long. What area does it sweep through in 30 seconds
skad [1K]

Exact Area = 98pi  

Approximate Area = 307.8760800518 (use calculator stored version of pi)

Approximate Area = 307.72 (using pi = 3.14)

Units are in square millimeters

======================================================

Explanation:

In 60 seconds, the hand sweeps out a full circle of radius 14. The area of this circle is

A = pi*r^2 = pi*14^2 = 196pi

Half of this is what the hand sweeps out in 30 seconds, so A/2 = (196pi)/2 = 98pi is the exact area it sweeps out. Your calculator would then show 98pi = 307.8760800518 approximately

If instead you use pi = 3.14, then the approximate area is 98*3.14 = 307.72

Find the value of x. I WILL GIVE YOU BRAINLIEST!!!!​
Elan Coil [88]

Hi there!

\large\boxed{x = 40}

We can solve for x knowing that the sum of interior angles in a triangle is 180°.

The square at the bottom indicates a right angle, or 90°. Therefore:

180 = 90 + x + (x + 10)

Combine like terms:

180 = 100 + 2x

Subtract 100 from both sides:

180 - 100 = 2x

80 = 2x

Divide both sides by 2:

x = 40.
