Answer:

Y=-4x

Step-by-step explanation:

Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x

Simplify the expression 7C4

Nady [450]

To simplify 7C4 we use the combination formula given by:
nCr=n!/[(n-r)!r!]
thus:
In our case we shall have:
n=7 and r=4
7C4
=7!/[(7-4)!4!]
=5040/[6×24]
=5040/144
=35

The answer is 35

The circumference of the circle is 9.42 inches, What is the diameter of the circle?

Elena L [17]

EXPLANATION

Since the circumference of the circle is 9.42, we can get the diameter by applying the following relationship:

$Circumference=2\pi r=2\pi\frac{d}{2}=\pi d$

Isolating the diameter:

$Diameter=\frac{Circumference}{\pi}$

Plugging in the numbers:

$Diameter=\frac{9.42}{3.14}=3$

Therefore, the diameter is equal to 3 inches.

Answer:

10x-2y

Step-by-step explanation:

distribute for both of them then multiply both answers by 2 and add them

2(x+y)= (2x+2y) x2= 4x+4y

3(x-y)= (3x-3y) x2= 6x-6y

4x+4y+6x-6x

10x-2y
