Answer:

Factoring.

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

y = 2x² - 6x - 8

0 = 2x² - 6x - 8

Step 2: Find roots

And we have our final answer!

Answer:

first take 2 out of the equation

y=2(x^2-3x-4)

then factor

y=2(x-4)(x+1)

then solve

(x-4)=0 .  (x+1)=0

x=4 .          x=-1

Answer:

The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Step-by-step explanation:

String distance between Fort Myers and Miami = 7 inches

A real life distance between Fort Myers and Miami = 154 miles

So, 7 inches = 154 miles

[tex]1 inch = \frac{154}{7}=22 miles[/tex]

Scale : 1 inch = 22  miles

String distance between Tampa and Orlando = 4 inches

Using scale

The real-life distance to the nearest mile between Tampa and Orlando = [tex]4 \times 22 = 88 miles[/tex]

Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Answer:

y intercept

Step-by-step explanation:

The [y-intercept] is the point where the line crosses the y-axis. Notice that the y-intercept occurs where x = 0, and the x-intercept occurs where y = 0.

Answer:

x = -6

Step-by-step explanation:

So you need to start by simplifying the equation. Subtract 4 from both sides.

3x - 6 = -24.

Now, you can add the 6 to both sides.

3x = -18.

You can now divide by 3 to get x.

x = -6

Answer:

her fee is $140 and she gets back $60

Step-by-step explanation:

step 1: multiply $20 by 7, which gives you 140

step too if you need how much money she gets back take 140 from 200 and you get $60

Answer:

4 is the maximum number of ride tickets she can buy

Step-by-step explanation:

Here, r represents the number of ride tickets and f represents number of food tickets.

The system of inequalities is given as:

r+f\geq 16                         ....[1]

4r+2f\leq 40                    .....[2]

To solve Mathematically:

Multiply equation [1] by -2 we have;

-2r-2f \leq -32               .....[3]

Add equation [2] and [3] we have;

2r \leq 8

Divide both sides by 2 we have;

r \leq 4

Since r must be less than or equal to 4.

You can also see the graph of the given system of inequalities as shown below.

The intersection point is, (4, 12)

Therefore, the maximum number of ride tickets she can buy is, 4

Answer:

t≤ 9

Step-by-step explanation:

3.5+4t≤ 39.5

subtract 3.5 from each side

4t≤ 36

divide each side by 4

t≤ 9

Answer:

t ≤ 9

Step-by-step explanation:

3.5 + 4t ≤ 39.5

3.5 + 4t - 3.5 ≤ 39.5 - 3.5

4t ≤ 36

4t ÷ 4 ≤ 36 ÷ 4

t ≤ 9

Answer:

Step-by-step explanation:

The sum of roots of quadratic ax^2 +bx +c = 0 is -b/a. Here, that means the sum of roots is ...

  -(-4)/4 = 1

The sum of the roots is 1.

Answer:

1/2

Step-by-step explanation:

By Vieta's formulas, the sum of the roots of $ax^2 + bx + c$ is given by $\dfrac{-b}{a}$. For this quadratic, that value is

\[ \frac{-b}{a} = \frac{-(-4)}{4} = 1.\]

Since the sum of the roots is $1$, the average of the roots is $\boxed{\dfrac 1 2}$.

Alternately, we could factor $4$ out of every term of this quadratic, giving $4(x^2 - x - 1)$. Since $4 \cdot 0 = 0$, any number that is a root of $x^2 - x - 1$ will also be a root of $4(x^2 - x - 1)$. Thus, the problem can change to finding the sum of the roots of $x^2 - x - 1$.

Since the coefficient of the linear term is $-1$ and this is the opposite of the sum of the roots, we find that the sum of the roots is equal to $1$, and the average is $\boxed{\dfrac 1 2}$.

Answer:

x=5 y=130

Step-by-step explanation:

27x-5 and 11x-5 = 180

27x-5 + 11x-5 = 180

38x- 10= 180

38x= 190

x=5

11(5)-5 = 50

50 + y= 180

y= 130

Answer:x=-32

Step-by-step explanation:

Answer

[tex]3x ^{2} - 6x + 8 + \frac{4}{x + 2} [/tex]

Step-by-step explanation:

use synthetic division-

1. but all the coefficients in a box

2. put the divisor term equal to 0 so... x+2=0 ,x would have to equal negative 2 x= -2

3. drop the first coefficient

4. multiply the number outside the box by the number you just dropped and put it under the second coefficient. then subtract

5. keep repeating steps four

6. once youre done the last term below the box is your remainder and should be written as +remainder over divisor which in this case is x-2

7. everything is backwards soo the 8 would be your constant, the -6 is your x and 3 is your x^2 term.

Answer:

Step-by-step explanation:

0.3

Answer:

Step-by-step explanation:

Given the simultaneous inequality

2x+y<10  ....... 1

2x-4y<8  ....... 2

Subtract both equation from each other

(2x-2x)+(y-(-4y))<10-8

0+5y<2

y < 2/5

y < 0.4

Substitute the given value of y into 1;

2x+y<10

2x + 2/5 < 10

2x < 10 - 2/5

2x < 48/5

10x < 48

x < 4.8

Hence the solution to the inequality expressions is (4.8, 0.4)

Answer:

x = 2 pizzas

Step-by-step explanation:

Let

x = number of pizza ordered

Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered.

cost for a party at Stella’s Pizza = 16 + 8x

Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered.

cost for a party at Napoli’s Pizza = 24 + 6x

Equate the cost for a party at Stella’s Pizza and cost for a party at Napoli’s Pizza

16 + 8x = 24 + 6x

8x - 6x = 24 - 16

2x = 8

x = 8/4

= 2

x = 2

Step-by-step explanation:

Starting 3 feet from the motion detector, you will be at the point (0, 3) on the graph.

A normal walking speed is about 3 mph, or about 4.4 feet per second. So, walking slowly may be something less than 2 feet per second. In the attached graph, we show a walking speed of about 4 feet in 10 seconds, a really slow speed. Since you're walking away, the distance is increasing with time.
