–0.4(3x – 2) + StartFraction 2 x plus 4 Over 3 EndFraction for x = 4
Nadusha1986 [10]

Answer:

0

Step-by-step explanation:

Given

- 0.4(3x - 2) + \frac{2x+4}{3} ← substitute x = 4 into the expression

= - 0.4(3(4) - 2) + \frac{2(4)+4}{3}

= - 0.4(12 - 2) + \frac{8+4}{3}

= - 0.4(10) + \frac{12}{3}

= - 4 + 4 = 0

lesya [120]

Answer: <em>ok so if 60% is under 25 then we can assume 40% is over 25, and then do 40% of 450,000, which is 180,000 .</em>

<em>so we can say that 180,000 people in the town are over 25 years old</em>

Find the equation of the line. Use exact numbers. y=y=y, equals x+x+x, plus
Nuetrik [128]

The equation of a line that is passing through the points (0, 4) and (1, 6) will be y = 2x + 4.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A coordinate plane. The x-axis and y-axis are each scaled by one.

A graph of a line goes through the points (0, 4) and (1, 6) will be

The equation of a line that is passing through the points (0, 4) and (1, 6) will be

y - 4 = [6 - 4 / 1 - 0] (x - 0)

y - 4 = 2x

    y = 2x + 4

The graph is given below.

More about the linear system link is given below.
