7 x 0.04=7 x 4 x Write a decimal to complete the equation

Mathematics
1 answer:
S_A_V [24]3 years ago
6 0
Solution:

1) Cancel 7 on both sides
x\times 0.04=x\times 4x

2) Regroup terms
0.04x=x\times 4x

3) Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}
​​
0.04x={x}^{2}\times 4

4) Regroup terms
0.04x=4{x}^{2}
​​
5) Move all terms to one side
0.04x-4{x}^{2}=0

6) Factor out the common term xx
x(0.04-4x)=0

7) Solve for x
x=0,0.01

Done!

Can anyone help me ? I just need the numbers

Answer:

<em>(-6, 0) and  (0, 1.5)</em>

<em></em>

Step-by-step explanation:

The equation of the line in pint slope form is expressed as;

y-y0= m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given

m = 1/4

(x0, y0) = (6,3)

Substitute into the formula;

y - 3 =  1/4(x-6)

4(y-3) = x - 6

4y - 12 = x-6

4y - x = -6+12

4y - x = 6

x = 4y - 6

To get the points to plot, we will find the x and y-intercept of the resulting expression.

For the x-intercept,

at y = 0

x = 4(0) - 6

x = -6

Hence the x-intercept is at (-6, 0)

For the y-intercept,

at x = 0

0 = 4y - 6

4y = 6

y = 6/4

y = 3/2

y = 1.5

Hence the y-intercept is at (0, 1.5)

<em>Hence the required points to plot to get the required line are  (-6, 0) and  (0, 1.5)</em>

How do I do #1 ? Help!!
juin [17]

1) First find the multiplier.

Look at the 0 and 1st term you have 5 as the 0 and 3 as the 1st term.

2)Ask how do we get from 5 to 3?

  • We subtract 2 so the multiplier is -2

3)Lets make a linear equation: y=mx +b

  • m= multiplier or slope
  • x= Just equals x value
  • b= your starting value or the 0 term which is 5

4)Use the values that you have to create your equation.

  • y=-2x +5

Note:For the x value just plug in the x value from your table.

Ex.

  • y=-2(-10)+5
  • y=20+5
  • y=25
