Answer:

Step-by-step explanation:

The given equation is,

$\Rightarrow ax = 6$

$\Rightarrow x = \dfrac{6}{a}$

We need to to find all the whole values of a for which the solution of the equation i.e x will be a whole number.

We know that when a number is divided by one of its factor it leaves a remainder of 0 or the result we get is a whole number.

That is why, we need a as one of the factors of 6, i.e 1, 2, 3, 6 in order to get x as a whole number.

Consider the following equation, bh + hr = 25 when solving for h

Eva8 [605]

Answer:

h = $\frac{25}{b+r}$

Step-by-step explanation:

Given

bh + hr = 25 ← factor out h from each term on the left side

h(b + r) = 25 ← divide both sides by (b + r)

h = $\frac{25}{b+r}$

What is -4,2 and -6,0 y= what

elena-s [515]

Hey there! :D

First, find the slope:

m= (y2-y1)/(x2-x1) (-4,2) and (-6,0)

m= (0-2)/(-6-(-4)
m= -2/(-6+4)
m=-2/-2
m=1

Now, plug that into point slope.

y-y1= m(x-x1)

y-2= 1(x-(-4)
y-2=1(x+4)
y-2=x+4

Add two to both sides.

y=x+6

The y-intercept= 6

I hope this helps!

If 5/4x + 1/2 = 2x - 1/2 what is x

stellarik [79]

Answer:

$x=\frac{4}{3}$

Step-by-step explanation:

We can solve the equation by isolating x through order of operations. We use PEMDAS in reverse by undoing SADMEP or subtraction, addition, division, multiplication, exponents, and parenthesis.

$\frac{5}{4}x+\frac{1}{2} =2x-\frac{1}{2}$

1. We simplify any parenthesis. Have none. So move on to the next step!

2. We undo any subtraction or addition by doing the inverse on both sides.

$\frac{5}{4}x+\frac{1}{2}-\frac{1}{2} =2x-\frac{1}{2}-\frac{1}{2} \\\frac{5}{4}x =2x-1$

3. Now subtract an x term from both sides.

$\frac{5}{4}x-2x =2x-2x-1\\\frac{5}{4}x -\frac{8}{4}x =-1\\-\frac{3}{4}x=-1$

4. Divide both sides by the coefficient of x.

$-\frac{3}{4}x =-1\\x=-\frac{4}{3} (-1)\\x=\frac{4}{3}$
