I need help from MATH 9 - Linear Relation 1: The slope and the y-intercept Form <img src="https://tex.z-dn.net/?f=y%3Dmx%2Bb%3A"

SashulF [63]

Answer:i think it is y-y1=m(x-x1)

m is herein undefined.

Slope, m, is defined as change-of-y divided by change-of-x...

m=(y-y1)/(x-x1)

The mathematical concept of undefined means that the denominator is zero. This means that both values of x are equal.

(-4,-8)

This equation is x=-4

It is a vertical line and includes the point of y=-8.

What is the solution to the equation 7^3x ≈ 9 ?

egoroff_w [7]

$7^{3x}\approx9\\\\\log_77^{3x}\approx\log_79\\\\3x\approx\log_79\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{x\approx\dfrac{\log_79}{3}=\frac{1}{3}\log_79=\log_79^\frac{1}{3}=\log_7\sqrt[3]9}$

425 students in the 9th, 10th, and 11th grades were asked if they ride the bus to school. The results are shown in the two-way f

Ipatiy [6.2K]

The true statements are:

44/85 of the student surveyed do not ride the bus to school
About 32% of the students are in the 9th grade

The false statements are:

64% of the students are 11th graders
134/150 of the students surveyed are in 9th or 10th grade

<h3>How to interpret the two-way frequency table</h3>

<u>The students that do not ride bus to school</u>

From the table, 220 students do not ride bus to school.

So, the proportion of students that do not ride bus to school is:

$p=\frac{220}{425}$

Simplify

$p=\frac{44}{85}$

Hence, this statement is true

<u>The 9th graders </u>

From the table, 134 students are 9th graders

So, the proportion of students that are 9th graders is:

$p=\frac{134}{425}$

Divide

$p=0.315$

Approximate, and represent as percentage

$p=32\%$

Hence, this statement is true

<u>The 11th graders </u>

From the table, 141 students are 11th graders

So, the proportion of students that are 11th graders is:

$p=\frac{141}{425}$

Divide

$p=0.331$

Approximate, and represent as percentage

$p=33\%$

Hence, this statement is false

<u>The 9th or 10th graders </u>

From the table, 134 + 150 students are 9th or 10th graders

So, the proportion of students that are 11th graders is:

$p=\frac{134 + 150}{425}$

$p=\frac{284}{425}$

Hence, this statement is false
