HI PLS HELP!!! A student scored 83 and 91 on their first two quizzes. Write and solve a compound inequality to find the possible values for a third quiz score that would give them an average between 85 and 90, inclusive.

Answer:

Step-by-step explanation:

Slope of this line will be= m= (600-200)/(1-5)

m = 400/-4 = -100

Eq of line will be:

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

y-200=-100(x-5)

y-200+100x-500=0

100x+y-700 = 0

To write equation in slope-intercept form

y=mx+c

just seperate "y"

y=-100x+700

Hey there!

The answer to your question is [tex]y = -100x + 500[/tex]

To write this equation in slope-intercept form, first we must figure out the slope. We can do this using the formula

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]:

[tex]\frac{200-600}{5-1}[/tex]

[tex]\frac{-400}{4}[/tex]

[tex]-100[/tex]

Now, we have part of the equation: y = -100x + b. We have to find b, and we can do so by plugging in one of the points into the equation, like so:

[tex]600 = -100(1) + b[/tex]

[tex]600 = -100 + b[/tex]

[tex]500 = b[/tex]

Now, we have our equation:[tex]y = -100x + 500[/tex]

Hope it helps and have an amazing day!

Answer:

Neither

Step-by-step explanation:

The slope of PQ is -3.

The slope of RS is 3.

Parallel lines have the same slope. The slopes for perpendicular lines are the opposite of the reciprocal. PQ and RS are intersecting lines, but not parallel or perpendicular.

Answer:

20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).

Step-by-step explanation:

The day of the week is a distraction.  All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.

Answer:

After paying her suppliers, she made $4,575.

Step-by-step explanation:

First, you have to multiply the number of pounds purchased for the price:

$1.29*1250=$1,612.5

$1.50*1500=$2,250

Now, you can add both amounts to find the total cost:

$1,612.5+$2,250=$3,862.5

Now, you have to find the total amount of lb purchased and determine the kg they represent given that 1 kg is equal to 2.20 lb:

1250+1500=2750

2.20 lb  →  1 kg

2750 lb →    x

x=(2750*1)/2.20= 1250 kg

Now, you can find the total amount sold by multiplying the price per kilogram for the amount of kg:

$6.75*1250=$8,437.5

Finally, you have to subtract the total cost from the total amount sold:

$8,437.5-$3,862.5=$4,575

According to this, the answer is that after paying her suppliers, she made $4,575.

Answer:

Slope/m=1/2, y-intercept=-4

Step-by-step explanation:

Y=mx+b is slope-intercept form. So in the equation y=1/2x-4, m stands for the slope, and in the equation 1/2 is in the place of m. B stands for the y-intercept, and in its place is -4.

Ahem, I'm writing with a mouse, excuse the scraggly lines and writing on the graph.

Soil is often considered an abiotic factor since it is mostly made up of small particles of rock (sand and clay) mixed with decomposed plants and animals. Plants use their roots to get water and nutrients from the soil.

Also just a tip, make sure to put it in the correct category next time cause someone can report it :(

Anyways hope this helps!! :D

Answer:

8. 7

9. 9

Step-by-step explanation:

27/12 times 4 is 9, 9-2 is 7

3x-18=x

2x=18

x=9

Step-by-step explanation:

Decreased by 92% = 8% of original

8% of original value = New value = 13.12

100% of original value = 13.12 * (100/8) = 164.

The original value is 164.

Step-by-step explanation:

becuase I need pointssss

Answer:

y=5/3x+7/3

Step-by-step explanation:

Here are the points: (1,4) and (-2, -1)

let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)

label the points:

x1=1

y1=4

x2=-2

y2=-1

now subsitute into the equation

m=(-1-4)/(-2-1)

m=-5/-3

m=5/3

the slope of the line 5/3

Here's the equation so far:

y=5/3x+b (b is a place holder)

we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>

let's use (1,4) as an example

4=5/3(1)+b

4=5/3+b

subtract 5/3 from both sides

7/3=b

Now, put it all together:

y=5/3x+7/3

Hope this helps!

Answer:

(-2, 1) and (0, 3) has the slope of m = 1 and the equation is y = x + 3

(0, -2) and (3, -5) has the slope of m = 1 and the equation is y = -x - 2

Answer:

256 m and 3840 m²

Step-by-step explanation:

The 3 part of the ratio represents 48 m , then

48m ÷ 3 = 16 m ← value of 1 part of the ratio, so

5 parts = 5 × 16 m = 80 m

Then breadth = 48 m and length = 80 m

perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m

area = lb = 80 × 48 = 3840 m²

Answer:

[tex]5\ \text{ft}[/tex]

Step-by-step explanation:

Perimeter of rectangular lot = [tex]448\ \text{ft}[/tex]

The width of the easement is [tex]x\ \text{ft}[/tex]

Buildable area 140 ft by 64 ft

[tex]2(140+2x)+2(64+2x)=448\\\Rightarrow 140+2x+64+2x=\dfrac{448}{2}\\\Rightarrow 204+4x=224\\\Rightarrow x=\dfrac{224-204}{4}\\\Rightarrow x=5\ \text{ft}[/tex]

The width of the easement is [tex]5\ \text{ft}[/tex].

Answer:

Andy's claim is incorrect

Step-by-step explanation:

Given

Mike:

[tex]Tuesday = \frac{2}{4}[/tex]

[tex]Wednesday = \frac{1}{3}[/tex]

Andy:

[tex]Tuesday = \frac{1}{2}[/tex]

[tex]Wednesday = \frac{1}{5}[/tex]

Required

Is Andy correct?

First, we need to calculate the fraction of book read by Mike.

[tex]Mike = \frac{2}{4} + \frac{1}{3}[/tex]

Take LCM

[tex]Mike = \frac{6+4}{12}[/tex]

[tex]Mike = \frac{10}{12}[/tex]

Convert to decimal

[tex]Mike = 0.833\\[/tex]

Next, we perform the same calcuation for Andy

[tex]Andy = \frac{1}{2} + \frac{1}{5}[/tex]

Take LCM

[tex]Andy = \frac{5+2}{10}[/tex]

[tex]Andy = \frac{7}{10}[/tex]

Convert to decimal

[tex]Andy = 0.70[/tex]

Andy's claim that he read more of the book is incorrect because 0.833 (for Mike) is greater than 0.70 (for Andy)
