factor the equation a² - a - 12

Answer:

the square root of 20 could be between 4 and 5 OR -4 and -5.

Step-by-step explanation:

plus or minus 4 squared is 16 and plus or minus 5 squared is 25. finally, 20 is between 16 and 25.

Answer:

[tex]6mx - 3nx + my[/tex]

Step-by-step explanation:

2my - my = 1my (1 can also be omitted).

Answer:

6mx-3nx+my

Step-by-step explanation:

Collect like terms:

6mx-3nx+2my-my

subtract: 2my-1my

= 1my

since you cant add any more like terms your answer would be

6mx-3nx+my

Answer:

Yes, all equilateral triangles are acute.

Step-by-step explanation:

yea

hope this helps :)))

Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

Answer:

5

Step-by-step explanation:

Because -5 is a negative number and the opposite of negative is positive and 5 is positive.

Final Answer: [tex]5[/tex]

Steps/Reasons/Explanation:

Write down [tex]-5 + x = 0[/tex] because this is our equation with [tex]-5[/tex] plugged in to get an additive inverse. We will have to add [tex]5[/tex] to both sides. This means our additive inverse is positive [tex]5[/tex].

Question: Which number is the additive inverse of [tex]-5[/tex]?

[tex]-5 + x = 0[/tex]

Step 1: Regroup terms.

[tex]x - 5 = 0[/tex]

Step 2: Add [tex]5[/tex] to both sides.

[tex]x = 5[/tex]

Step-by-step explanation:

The zeros of 3x+1

3x=-1

x=-⅓

plug in -⅓ into the trinomial. if it gives an answer of 0 then it's a factor

Answer:

8

Step-by-step explanation:

simplify the expression

3x - 4x+8 = 0

put like terms together 3x-4x = -x

-x + 8 = 0

add x on both sides

x = 8

Step-by-step explanation:

STEP 1:

Equation at the end of step 1

 (3x - 4)2  = 0

STEP 2:

Solving a Single Variable Equation:

2.1      Solve  :    (3x-4)2 = 0

 (3x-4) 2 represents, in effect, a product of 2 terms which is equal to zero

For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means :   3x-4  = 0

Add  4  to both sides of the equation :

                     3x = 4

Divide both sides of the equation by 3:

                    x = 4/3 = 1.333

One solution was found :

x = 4/3 = 1.333

Answer:

984 adults

281 teens

492 children

Step-by-step explanation: Multiply the total by the corresponding percentage to find the number. We assume the percentages have been rounded, so some adjustment is needed in the result of the multiplication.

{adults, teens, children} = 1757 × {.56, .16, .28} = {983.92, 281.12, 491.96}

 ≈ {984, 281, 492}

Answer:

984

because x should not be the same in more than one pair

Answer:

-½(30) = -15

Step-by-step explanation:

Marta's pool decrees ½ inch each day, so that would be -½ each day. You would take that -½ and multiply it by 30 so you can find out the decrees in inches over 30 days so the equation would be -½ × 30 = -15 (im sorry if that didn't make sense)

Answer:

$2800.00

Step-by-step explanation:

A total accrued amount 800 = principal (P) $2000 + interest (I)

R Rate of interest per year decimal - 0.08

X Rate of interest per year percentage - 8%

T time period months or years - 5 years

Equation will be A = P (1 + RT)

first convert X to R = percentage to decimal

X = R/100 = 8%/100 = 0.08 per year

Solving:

A = 2000 (1 + (0.08 x 5)) = 2800

A = $2800
