He equation 8 − 4x = 0 has real solution(s)

Mathematics

Rzqust [24]3 years ago

Answer:

1 real solution, x=2

Step-by-step explanation:

Let's solve for x and see how many solutions exist.

To solve for x, we must get x isolated. To do this, perform the inverse operation to both sides of the equation.

8-4x=0

4x is being subtracted from 8. The inverse, or opposite, of subtraction is addition. Add 4x to both sides.

8-4x+4x=0+4x

8=0+4x

8=4x

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.

8/4=4x/4

8/4=x

2=x

x is equal to 2, therefore there is 1 real solution.

Answer:

x=-2

divide by -4

you get x=-2

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

  • (1,3)
  • (2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

<h3><u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> line</u><u> </u><u>is </u><u>y </u><u>=</u><u> </u><u>-2x </u><u>+</u><u> </u><u>5</u><u>.</u></h3>

Help me pleasee!!!!!!!!!!!!
tresset_1 [31]

Answer:

Step-by-step explanation:

Angles 1, 2, and 3 are supplementary (they add up to equal 180). If angles 1 and 3 are 20 each, then their sum in 40, making angle 2

180 - 40 = 140. If this central angle is 140 degrees, then the measure of the arc that it cuts off also measures 140 degrees. This is not to be confused with the arc length, which is not even remotely the same thing!
