*PLEASE HURRY* WILL GIVE BRAINLIEST* Write the equation in the form ax^2 + bx+c=0 where a > 0, if necessary. Then identify the values of a, b, and c. Do not actually solve the equation
3x^2 = 4x + 8

*PLEASE HURRY* WILL GIVE BRAINLIEST* Write The Equation In The Form Ax^2 + Bx+c=0 Where A > 0, If

Answers

Answer 1

Answer:

a= 3

b=-4

c=-8

Step-by-step explanation:

3x²=4x+8

since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0

3x²-4x- 8= 0

the above equation is now in the form required

ax²+bx+c=0

so substitute the values according and u will see that a= 3

b=-4 and c=-8

hope this helps

Elena wants to make a scale drawing of her bedroom. Her bedroom is a rectangle with length 5 m and width 3 m. She decides on a scale of 1 to 50. Elena's bedroom door is 0.08 m. How wide should the door be on the scale drawing? Elena's bed measures 4 cm by 3 cm on the scale drawing. What are the actual measurements of her bed

Answers

Given:

Bedroom is a rectangle with length 5 m and width 3 m.

Elena's bedroom door is 0.08 m.

Elena's bed measures 4 cm by 3 cm.

Scale of drawing is 1 to 50.

To find:

The width of door on the scale drawing.

Actual measurements of her bed.

Step-by-step explanation:

Scale of drawing is 1 to 50.

It means, the length of sides in drawing is [tex]\dfrac{1}{50}[/tex] of actual.

Elena's bedroom door is 0.08 m.

1 m = 100 cm

0.08 m = 8 cm

Door on the scale drawing [tex]=\dfrac{1}{50}\times 8[/tex]

                                             [tex]=0.16[/tex]

Therefore, the Door on the scale drawing is 0.16 cm wide.

Elena's bed measures 4 cm by 3 cm on the scale drawing.

Elena's bed actual measurements are

[tex]4\times 50=200cm=2m[/tex]

[tex]3\times 50=150cm=1.5m[/tex]

Therefore, the actual measurements of her bed is 2 m by 1.5 m.

8x = 10x + 20


Could you guys explain as well?

Answers

Answer:

x= -10

Step-by-step explanation:

-8x+10x+20=0

2x+20=0

2x=0-20

2x=-20

x=-20/2

x= -10

Answer:

x = -10

Step-by-step explanation:

8x (-10x)= 10x +20 (-10x)

subtract 10x from both sides of the equation

-2x/-2 = 20/-2

divide both sides by -2

x = -10

Answers

Answer:

The slope of the line is  [tex]\frac{-5}{3}[/tex] ⇒ D.

Step-by-step explanation:

The rule of the slope of a line is

m =  [tex]\frac{y2-y1}{x2-x1}[/tex]  (x1, y1) and (x2, y2) are two points lie on the line

Use the given figure to find two points on the line

→ From the given figure

∵ The line passes through points (0, 2) and (3, -3)

∴ x1 = 0 and y1 = 2

∴ x2 = 3 and y2 = -3

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-3-2}{3-0}=\frac{-5}{3}[/tex]

∴ m = [tex]\frac{-5}{3}[/tex]

∴ The slope of the line is  [tex]\frac{-5}{3}[/tex]

Solve 6kx = 4kx + 8 for x.
Start by collecting the variable terms on the same side of the equation.

What is the first step?

Answers

Answer:

x = 4k

Step-by-step explanation:

6kx = 4kx + 8

The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.

2kx = 8

Next, move the 2k to the right side of the = by dividing both sides by 2k

x = 8/2k

The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.

x = 4k
