3x-6+4=-20
I need a break down on how to solve it
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
P is directly proportional to u.
Answer:
?????????????????????????
Step-by-step explanation:
????????????????????????
Answer:
[tex]\frac{p}{u} =k[/tex]
Step-by-step explanation:
A direct proportion means the ratio of p:u is a constant numberThis constant number is denoted by kan example of this is, say for every 1 chicken you buy there are 2 legs which is ratio 1:2 which is [tex]\frac{1}{2}[/tex] so if you add more chickens, you add more legs, 2 chickens means 4 legs, 8 chickens means 16 legs, which is [tex]\frac{1}{2}= \frac{2}{4} =\frac{8}{16} =0.5[/tex] so the constant number is 0.5, so this a direct proportionThe two values grow at the same rateUse partial products and the distributive property to calculate the product.

What is the result when 3x^3-x^2-4x+20 is divided by x+2?
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.

For an activity in class, students used pieces of string to measure roads on a map. They used a map scale to determine the
distance between two cities. One group measured the distance between Fort Myers and Miami on a Florida state map. The string
distance was 7 inches, which represents a real-life distance of about 154 miles. Another group measured the distance between
Tampa and Orlando on the same map and found that distance to be 4 inches.
The students need to figure out what the distance is from Tampa to Orlando. They begin to set up the following table. Complete the
table for them.
Inches
Miles
What is the real-life distance to the nearest mile between Tampa and Orlando?
2 3 4 5 6
Next
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

How would you find the solutions to this quadratic equation y=2x^2-6x-8
Answer:
Factoring.
General Formulas and Concepts:
Algebra I
FactoringFinding roots of quadraticsStep-by-step explanation:
Step 1: Define
y = 2x² - 6x - 8
0 = 2x² - 6x - 8
Step 2: Find roots
Factor 2: 0 = 2(x² - 3x - 4)Factor: 0 = 2(x - 4)(x + 1)Find roots: x = -1, 4And 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
A comer store sells two kinds of baked goods: cakes and pies. A cake costs $8 and a pie costs $11. In one
day, the store sold 11 baked goods for a total of $112. How many cakes did they sell?
a. 3 cakes
c. 2 cakes
b 11 cakes
d. 8 cakes
Answer:
8 number of cakes were sold.
Step-by-step explanation:
Out of 12 baked goods sold , let the number of cakes sold be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8 Therefore, 8 cakes were sold [Ans]
Answer:
3 cakes
Step-by-step explanation:
3x8=24
112-24=88
88/11=8
3cakes +8 pies= 11 baked goods

Two pizza parlors in town are offering special rates to attract group reservations. Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered. Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered. Compare the costs of holding an event at the two pizza parlors.
Write and solve a system of linear equations to model the cost of an event at each pizza parlor.
a. Write an equation to represent the cost for a party at Stella’s Pizza.
b. Write an equation to represent the cost for a party at Napoli’s Pizza.
c. What is the solution to the system of equations? (label your answers)
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
What is the sum of the roots of the quadratic $4x^2 - 4x - 4$?
9514 1404 393
Answer:
1
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 $\boxed{\dfrac 1 2}$.

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
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

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
