a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.

Answers

Answer 1

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is  [tex]length\times width[/tex]

Area= [tex](3x+3)x<90[/tex]

[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Step-by-step explanation:

Answer:

y= -5x+8

Step-by-step explanation:

So frstt you gotta know the form

y= mx+b

y= random Y-coordinate (not useful in this situation)

m= slope

x= random X coordinate (not useful in this situation)

b= y-intercept (the first point of the line that hits the y axis)

So first lets find the slope

sure we can use the slope formula between 2 points but I just did rise over run since this is an easy graph

Rise 5 and go Left 1 so the slope is -5/1 or -5 (negative due to the run going left instead of right plus the line is negative since its falling from left to right)

The y intercept is 8 becuase its the first point where the line crosses the Y axis

ANd thats it!

Plug it in

y= -5x+8

if 1/2x^2 - 1/4 x + 3 what is the value of x = 8 ?

Answers

Answer:

If x=8 then the equation is equal to 33

If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35

Step-by-step explanation:

Given:

1/2x^2-1/4x+3

Two solutions possible:

If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33

If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0

factoring:

(.707x+2.11)(.707x-2.37)=0

.707x=-2.11 and .707x=2.37

x=-2.98 and x=3.35 rounded to 2 places

GIVING BRAINLIEST SYSTEM OF EQUATIONS!!!!!!!!

Answers

Answer:

the grid supports the answer

Answer:

Step-by-step explanation:

The given equations are in standard form, first write them in slope-intercept form.

"p" is the variable in the x-axis

"g" is the variable in the y-axis

First equation

[tex]4p+2g=96\\2g=96-4p\\\frac{2g}{2} =\frac{96}{2} -\frac{4p}{2} \\g=-2p+48[/tex]      

Second equation

[tex]3p+1g=60\\g=60-3p \\[/tex]

Next you have to determine two points for each equation, the easiest point to determine is the y-intercept, just replace the formula with p=0

First equation

for p=0

[tex]g=-2p+48\\g=-2.0+48\\g=48[/tex]

The  first point is (0,48)

For p=10

[tex]g=-2.10+48\\g=-20+48\\g=28[/tex]

The second point is (10,28)

Plot the points and link them with a line.

Second equation

For p=0

[tex]g=-3p+60\\g=-3.0+60\\g=60\\[/tex]

The first point is (0,60)

For p=10

[tex]g=-3.10+60\\g=30\\[/tex]

The second  point is (10,30)

Plot both points and link them to determine the line.

7x - 2x = 2y + 7y
