Answer:
(-3, 0), (0, -9)
Step-by-step explanation:
x-intercept: Let y = 0 and find x: 0 = -3x - 9), or 3x = -9. Then x = -3, and the x-intercept is (-3, 0).
y-intercept. Let x = 0 and find y. y = -3(0) - 9 = -9. The y-intercept is (0, -9).
Answer:
y = -2x + 3
Step-by-step explanation:
The given equation is:

First we need to find the slope of the tangent line. This can be done by finding the derivative of the given function.

Slope of the tangent will be the value of the derivative at the given point. So the slope of tangent is:

Now we have slope of the tangent line and a point (0, 3) on the tangent. The point (0,3) is the y-intercept of the tangent line. So we can use slope-intercept form to directly write the equation of the line.
The slope intercept form of an equation is:
y = mx + c
where m is the slope and c is the y-intercept.
Using the values: m = -2 and c = 3, we get:
y = -2x + 3
This equation represents the tangent line
Answer:
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.
When you're converting from a smaller unit to a larger unit, divide.
When you're converting from a larger unit to a smaller unit, multiply.
W +Y =5000
20/100 x W= 30/100 X Y
W/5=3Y/10
10W=15Y
W=15Y/10=3Y/2
3Y/2+Y=5000
3Y+2Y=10,000
