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

Point, Line, and Plane

Step-by-step explanation:

The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.

You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.

Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).

Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)

Snorkel, mask, and flippers Slope intercept form: y = 2x + 10

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

Answer:

The answer is

[tex] - \frac{4}{3} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

[tex]m = \frac{3 - 7}{ - 1 - - 4} = \frac{ - 4}{ - 1 + 4} = - \frac{4}{3} \\ [/tex]

We have the final answer as

[tex] - \frac{4}{3} \\ [/tex]

Answer:

-2

Step-by-step explanation:

Answer:

  1 of 8: (729, 81, 9, 1)

  2 of 8: 1 = (-1)^0 = 2^0

  3 of 8: 1

Step-by-step explanation:

The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.

So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

In the order of the attachments, ...

3) 5^0 = 1

Answer:

60 baskets per hour

Step-by-step explanation:

given that every 2.5 hours, the machine produces 150 baskets

Goal: to express this production rate in number of baskets the machine can produce in 1 hour (i.e obtain the unit rate)

2.5 hours -------> machine produces 150 baskets

1 hour --------> machine produces 150 ÷ 2.5 = 60 baskets

hence the unit rate  of production is 60 baskets per hour

Answer:

The EZ Pay Plan because it would cost less than the 40 to Go Plan.

Step-by-step explanation:

You will have to calculate the amount that you would pay with each monthly plan if you have 200 minutes per month.

-EZ Pay Plan:

$0.15*200=$30

-40 to Go Plan:

$40+($0.05*200)=$40+$10=$50

According to this, the answer is that if you only want 200 minutes per month, you should choose the EZ Pay Plan because it would cost $30 which is less than the 40 to Go Plan that would cost $50.

Inequality Form: -1 < x < 7

Interval Notation: (-1, 7)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

6 more than y :    

3 times a number:

x ← a number    

5 less than the product of 10 and c :

10c   ← the product of 10 and c

14 more than 6 times t :

6t  ← six times t

The sum of x and y is 18:

x+y    ← the sum of x and y

A number minus 12 is y:

x - a number

Answer:

x=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(3x+8)=175

(5)(3x)+(5)(8)=175(Distribute)

15x+40=175

Step 2: Subtract 40 from both sides.

15x+40−40=175−40

15x=135

Step 3: Divide both sides by 15.

15x/15=135/15

x=9
