Answer: In the math club, there is one nine-year old, one eleven-year old, two twelve-year old, and 4 thirteen year olds.

Step-by-step explanation:

Every dot represents one person in each category. So in order to figure out the math club, you count the dots. For example, in the 12 column. There are 2 dots meaning there are 2 people who are twelve years old in the math club. Hope this helped!

The majority of the members are 13 years old (50/50 13 or younger). Most of the members are on the older side, with the exception of one member, who is significantly younger than the others.

A system of equations consists of a line s of the equation y = x – 5 and a line t that passes through the points (0, 2) and (8,

GenaCL600 [577]

Answer:

$\text{The slope of the line t:}\ m=-\dfrac{3}{4}\\\\\text{The y-intercept of the line t:}\ b=2\\\\\text{The equation of a line t in the slope-intercept form:}\ y=-\dfrac{3}{4}x+2$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (8, -4) and (0, 2) → b = 2.

Calculate the slope:

$m=\dfrac{2-(-4)}{0-8}=\dfrac{6}{-8}=-\dfrac{3}{4}$

Therefore the equation of a line t in the slope-intercept form is:

$y=-\dfrac{3}{4}x+2$

raketka [301]

Answer:

(See explanation below for further details).

Step-by-step explanation:

Let be a parametric curve represented by $x = 3\cdot t - 5$ and $y = 5\cdot t + 1$ , where $t$ is the parametric variable.

The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.

$t = \frac{x+5}{3}$ and $t = \frac{y-1}{5}$
