Answer:

1) set H = J

-x + 2 = 3x - 4

so the answer would be the 3rd one

Y= -x + 2 and y= 3x - 4
As these both equal y, you know that they both equal each other so
-x + 2 = 3x - 4
Third option :)

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>

The students that do not ride bus to school

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

The 9th graders

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

The 11th graders

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

The 9th or 10th graders

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

Kate begins solving the equation StartFraction 2 Over 3 EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals StartF

zubka84 [21]

Answer:

(B)The equation has one solution: x = 0.

Step-by-step explanation:

The equation Kate is solving is: $\dfrac{2}{3} (6x-3)=\dfrac{1}{2}(6x-4)$

$\dfrac{2(6x-3)}{3}=\dfrac{(6x-4)}{2}\\\dfrac{2*3(2x-1)}{3}=\dfrac{2(3x-2)}{2}\\4x-2=3x-2\\$Adding two both sides$\\4x=3x\\4x-3x=0\\x=0$

Therefore, the equation has one solution: x = 0.

Aubrey and Charlie are driving to a city that is 120 miles from their house. they have already traveled 20 miles ,and they are d

Phoenix [80]

Answer:

The linear function is $y=50x+20$

The reasonable domain is $0\ hours \leq x\leq 2\ hours$

Step-by-step explanation:

Let

x ----> the time in hours

y ---> the distance in miles

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The slope is $m=50\ \frac{miles}{hour}$

The y-intercept is $b=20\ miles$

substitute

$y=50x+20$

Find the domain for x

For y=120 miles

Find the value of x

substitute the value of y in the linear equation and solve for x

$120=50x+20$

$50x=120-20$

$50x=100$

$x=2\ hours$

therefore

The domain is the interval [0,2]

$0\ hours \leq x\leq 2\ hours$
