spin [16.1K]3 years ago

6 0

Answer:

x=.6

Step-by-step explanation:

Combine like terms on the same side

.2x and .8x

1x+3.4=4

subtract 3.4 from both sides

1x=4-3.4

x=.6

What is Y=2(3x+6)(5x-4)

Sliva [168]

Answer:

y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

Step-by-step explanation:

Given: y=2(3x+6)(5x-4)

Use the distributive property!: y=(6x+12)(5x-4)

Use the distributive property!: y=(5x(6x+12)-4(6x+12))

Use the distributive property!: y=(30x^2+60x)-(24x+48)

Remove parenthesis: y=30x^2+60x-24x+48y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

How do you rewrite 6/9 in two different ways

Naya [18.7K]

We have to represent the fraction $\frac{6}{9}$ in two different ways.

Let us multiply the numerator and denominator of the given fraction by '2'.

Therefore, $\frac{6}{9} = \frac{6 \times 2}{9 \times 2} = \frac{12}{18}$

Therefore, $\frac{12}{18}$ is the first way to represent the given fraction.

Now, Let us multiply the numerator and denominator of the given fraction by '3'.

Therefore, $\frac{6}{9} = \frac{6 \times 3}{9 \times 3} = \frac{18}{27}$

Therefore, $\frac{18}{27}$ is the second way to represent the given fraction.

Therefore, $\frac{12}{18}$ and $\frac{18}{27}$ are the different ways to represent the fraction $\frac{6}{9}$ .

What is the equation of the line passing through the points (–25, 50) and (25, 50) in slope-intercept form?

allochka39001 [22]

The equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form is y = 50. Hence, 4th option is the right choice.

The slope-intercept form of a line is written as y = mx + b, where m is the slope of the line, and b is the y-intercept.

The slope of a line passing through the points (x₁, y₁) and (x₂, y₂) can be calculated using the formula, slope (m) = (y₂ - y₁)/(x₂ - x₁).

Therefore, slope of the line passing through the points (-25, 50) and (25, 50) can be calculated as m = (50 - 50)/(25 - (-25)) = 0/(-50) = 0.

We can find the equation of the line using the point-slope formula, according to which, a line having a slope m and passing through the point (x₁, y₁) can be written as y - y₁ = m(x - x₁).

Therefore, the equation of the given line can be written as:

y - 50 = 0(x - 25)

or, y - 50 = 0,

or, y = 50.

Therefore, the equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form is y = 50. Hence, 4th option is the right choice.

Find limit as x approaches two of quantity x squared minus four divided by quantity x minus two. You must show your work or expl

Brut [27]

Answer:

Step-by-step explanation:

lim (x^2 - 4) / (x - 2)

x --> 2

When we plug x =2, we get

(2^2 - 4) / (2 - 2)

= (4 - 4)/(2 - 2)

= 0 /0

Which is undefined.

Now we have to use L'hospital rule. Which says we need to differentiate the numerator and the denominator and apply the limit.

When we differentiate x^2 -4, we get 2x

When we differentiate x -2, we get 1

lim 2x/1

x --> 2

Now apply, the limit x = 2

2(2)/1

= 4/1

= 4

Therefore, limit of this function is 4, when x tends to 2.

Hope you will understand the concept.

Thank you.
