f(x) = 2(x – 1)– 5 and g(x) = – 2x + 1 , determine the x-values of the points of intersection.

Answers

Answer 1

Answer:

             x = 2

Step-by-step explanation:

These are equations of lines with different slopes, so there is only one point of their intersect.

The point of intersect is where f(x) = g(x).

2(x - 1) - 5 = - 2x + 1

 +2x            +2x

2x - 2 - 5 + 2x = 1

       +7               +7

          4x = 8

        ÷4     ÷4

          x = 2

Answer 2

Answer: x = 2

Explanation:

From the way you were referring to the x-values as plural, I assumed there were multiple x-values and multiple points of intersection, but these are linear equations, so one x-value it is!

Simply f(x)=2(x-1)-5 into f(x)=2x-7. Just plug in 2x-7, in order to make it equal to -2x+1. That would make the equation 2x-7=-2x+1. Add 7 to both sides to make it 2x=-2x+8. Add 2x to both sides to make it 4x=8. Divide 4 to both sides and that results with x=2.

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y

Answers

Answer:

The product will be less than the second factor.

Step-by-step explanation:

Given the expression

[tex]\frac{4}{5}\:\times \:1\frac{2}{5}\:=y[/tex]

solving to determine the product value

[tex]y=\:\frac{4}{5}\times \:\:1\frac{2}{5}[/tex]

  [tex]=\frac{4}{5}\times \frac{7}{5}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]

  [tex]=\frac{4\times \:7}{5\times \:5}[/tex]

  [tex]=\frac{28}{5\times \:5}[/tex]

  [tex]=\frac{28}{25}[/tex]

As the value of the second factor is:

[tex]1\frac{2}{5}=\frac{7}{5}=1.4[/tex]

And the product value is:

[tex]y=\frac{28}{25}=1.12[/tex]

It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.

i.e. 1.12 < 1.4

Thus, the product will be less than the second factor.

Determine the value of x.
