Tina planted a tree that was 6 feet tall and grew 3 feet every year her neighbor planted a tree from a seed but it grew 6 feet e
Iteru [2.4K]

Tina planted a tree. It started at 6 feet and every year it grows another three feet. The expression representing this is 6 + 3x, where x represents years.

Tinas neighbor also planted a tree where each year (which we called x) it grows 6 feet. The expression to represent this is 6x.

If you want to know when they’ll be the same height, then you need to set the expressions equal to each other.

6 + 3x = 6x

To solve, first get the variable to one side

6 = 3x

Divide each side by 3

x = 2

The trees wi be the same height the 2nd year.

What is the slope and y-intercept of this graph?​
pantera1 [17]

9514 1404 393

Answer:

  $0 -- y-intercept

  $10 per hour -- slope

Step-by-step explanation:

We would need to see grid lines on the graph, or the point in the upper right corner to be sure. It appears as though the slope is about $40 / 4 h, or $10 per hour.

The y-intercept is the point at lower left, (0, 0).

In triangle RST, the measure of angle T=90°, the measure of angle R=82°, and TR=44 feet. Find the length of ST to the nearest te
ludmilkaskok [199]

Answer:

x=6.183ft

Step-by-step explanation:

From the question we are told that:

Angel of side T=90

Angel of side R=82

Length Side TR=44

Generally the equation for Angle of side ST \theta is mathematically given by

Since Angle in Triangle =180 therefore

 \theta=180-(90+82)

 \theta=8

Therefore Applying sine rule to get Length of ST x

 \frac{x}{sin\theta}=\frac{TR}{sin82}

 x=\frac{44}{sin82}*sin8

 x=6.183ft
