Answer:

X=1

Step-by-step explanation:

3x+1=4

3x=4-1

3x=3

x=1

Answer:

x>5

Step-by-step explanation:

If you plug in 5,  5-8>-3 that is -3>-3 so you know that x has to be greater than 5.

Answer:  solutions are the same, just written differently,    inequality sign is reversed when multiplying. Yes, both students are correct. When multiplying by –7, the inequality symbol+ is reversed. The answers are the same, just written differently.

Answer:

[tex]y = 4x - 5[/tex]

Step-by-step explanation:

rewrite the equation

[tex]x + 4y - 8 = 0 \\ 4y = - x + 8 \\ y = - \frac{1}{4} x + 2[/tex]

perpendicular slope is a negative reciprocal. we will use the negative reciprocal to find the y-intercept

[tex]3 = 4(2) + b \\ 3 = 8 + b \\ b = - 5[/tex]

Answer:

$247.50

Step-by-step explanation:

Hope this helps! Thanks.

Answer:

domain is the set of numbers you can use for x

Step-by-step explanation:

log_4(x+3)=y means

I mean it translates to

4^y=x+3

remember that x^m≥0 for all real values of x and m

it actually can equal 0 only when x=0 or when x is very small

so

therefor since 4^y>0, x+3>0 as well

solving we get

x>-3

all real numbers greater than -3

Answer:

30 more red apples

Step-by-step explanation:

let 'a' = # of green apples

let '4a' = # of red apples

a + 4a = 50

5a = 50

a = 10

# of red apples:  10(4) = 40

# of green apples:  10

Answer:

4. Ty    5. Store A

Step-by-step explanation:

4. 750/3 is 250,  800/4 is 200, and 950/5 is 190 so i think it would be Ty

         Andre           Rick                        Ty

5. for Store A- 4 pairs of jeans is $120 so if you divide that which is 120/4 it gives you 30 so it would mean your paying $30 for each pair of jeans

for Store B- 2 pairs of jeans  will cost you $100 so if you add 50+50 it gives you a hundred so it means your paying $50 for each pair of jeans

for Store C- 3 pairs of jeans is $99 so if you divide 99/3 its 33 which means you would be paying $33 dollars for each pair of jeans

so out of all of then Store A gives you the best deal.

Answer:

1 < x < 7

Step-by-step explanation:

1. Solve for 2(x - 3)

Step 1: Simplify both sides of the equation.

Step 2: Add 6 to both sides.

Step 3: Divide both sides by 2.

2. Solve for x + 5 > 6

Step 1: Subtract 5 from both sides.

3. Now that we know x is more than one but less than 7, we can write the solution as this: 1 < x < 7.

Therefore, the answer is 1 < x < 7.

Answer: 1. Solve for 2(x - 3) Step 1: Simplify both sides of the equation. Step 2: Add 6 to both sides. Step 3: Divide both sides by 2. 2. Solve for x + 5 > 6. Step 1: Subtract 5 from both sides.

Answer:

Step-by-step explanation:

8/4=2

6/2=3

The answer is B It basically just expressing the 2×(6+9)

The expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.

The distributive property is the property that expresses the distributive law of algebraic multiplication. Similarly, in polynomial expression we can use the distributive property, for example we can write a(c+b)  in the form of (ac+bc).

We have an expression:

= 2 × (6 + 9)

After applying the distributive property:

= (2 × 6) + (2 × 9)

= (12) + (18)

= 30

Thus, the expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.

Answer:

(n + 6) / -4 = 10

n + 6 = 10 × -4

n + 6 = -40

n = -40 - 6

n = -46

(n - 2) / -3 = -6

n - 2 = -6 × -3

n - 2 = 18

n = 18 + 2

n = 20
