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.

a card is drawn from a well-shuffled deck of 52 cards. Find the probability of drawing a 9 of spades.

Answers

Answer:

1/52

Step-by-step explanation:

To obtain the probability of drawing a 9 of spade from a deck of 52 cards ;

Probability = (number of required outcomes / number of total possible outcomes)

Number of Required outcomes = 1 (there is only one 9 of spade in a deck of 52 cards)

Hence,

P(9 of spade). = 1 / 52

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

Answers

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

[tex]60\:\times 2^{-2}[/tex]

[tex]=60\times \frac{1}{2^2}[/tex]             ∵ [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]

[tex]=\frac{1\times \:60}{2^2}[/tex]

[tex]=\frac{60}{2^2}[/tex]

[tex]=\frac{2^2\times \:3\times \:5}{2^2}[/tex]

[tex]=3\times \:5[/tex]

[tex]=15[/tex] gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

Answers

Answer:

Step-by-step explanation:

since the first equation is already simplifies to y = 2x plug in 2x for the y in the second equation and solve

x = -(2x) + 6

x = -2x + 6

3x = 6

x = 2

plug in our x to the original equation

y = 2(2)

y = 4

so our answer is (2,4)

hope this helps <3

Answer:

x = 2

Step-by-step explanation:

If y is 2x, and x is -y + 6, what's x?

So let's use substitution method. Just replace the -y in x = -y + 6 with 2x:

x = -y + 6

x = -2x + 6

add 2x to both sides

3x = 6

divide by 3

x = 2

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

1)

From the graph, taking the two points

(3, -5)

(-3, 5)

The slope between (3, -5) and (-3, 5) will be:

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{5-\left(-5\right)}{-3-3}[/tex]

[tex]m=-\frac{5}{3}[/tex]

Therefore, the slope is:

[tex]m=-\frac{5}{3}[/tex]

2)

1ST METHOD

We know that the y-intercept of the graph of the linear function can be determined by setting x=0 and solving for y

As the graph crosses the y-axis at x=0

From the graph, it is clear that:

at x=0, y=0

Thus, the y-intercept is: (0, 0)

2ND METHOD

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where 'm' is the slope and 'b' is the y-intercept

substituting the point (3, -5) and m=-5/3 in the slope-intercept form

[tex]y=mx+b[/tex]

[tex]-5=\frac{-5}{3}\left(3\right)+b[/tex]

[tex]\frac{-5}{3}\left(3\right)+b=-5[/tex]

[tex]-5+b=-5[/tex]

[tex]b=0[/tex]

Thus, the y-intercept is: (0, 0)

3)

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

substituting m=-5/3 and b=0 to determine the equation line in the slope-intercept form

[tex]y=\frac{-5}{3}x+0[/tex]

Therefore, the equation line in the slope-intercept form is:

[tex]y=\frac{-5}{3}x+0[/tex]

where m=-5/3 and b=0
