Answer:

-12,0

Step-by-step explanation:

i took the quiz

Answer:

The x intercept is -12

Step-by-step explanation:

Because we need to find the x intercept (x,0)

We can substitute y or F(x) into 0

0=x+12

Subtract 12 on both sides

x=-12

so (-12,0) or -12

Answer:

11a−29b−50

Step-by-step explanation:

Hope this helps brodie

The simplified expression for ‐3 + 7(a – 3b – 1) – 4(10 – a + 2b) is 11a - 29b - 50.

To simplify the expression -3 + 7(a - 3b - 1) - 4(10 - a + 2b), we can apply the distributive property and combine like terms:

-3 + 7(a - 3b - 1) - 4(10 - a + 2b)

= -3 + 7a - 21b - 7 - 40 + 4a - 8b

= (7a + 4a) + (-21b - 8b) + (-3 - 7 - 40)

= 11a - 29b - 50

Therefore, the simplified expression is 11a - 29b - 50.

Answer:

7 counselors

Step-by-step explanation: 39 cannot be broken into 6 evenly, so you would either have 3 extra students without a counselor, or half of a counselor walking around, so 7.

Step-by-step explanation:

we are to first collect like terms here I mean all numbers that look alike are to be out on the same side so we are now going to have.

[tex]2 - 8x > 34[/tex]

[tex] - 8x > 34 - 2[/tex]

[tex] - 8x > 32[/tex]

now we are to divide both sides with the coefficient of x and we are to get

[tex] - 8x \div - 8 < 32 \div - 8 = x < 4[/tex]

At 2:25, the distance between the tip of the hour hand and the minute will be greater.

The distance between the hour hand and the minute hand is measured in degrees and the higher the degree, the greater is the distance between the tip of the hour hand and the tip of the minute hand.

From an hour to another;

So, starting from 12 toward the clockwise direction, the tip of the hour shift twice; i.e.

= 2 × 30°

= 60°

Now, in 2hr : 20 minutes, the distance is:

[tex]\mathbf{= 60+(\dfrac{20}{60})\times 30^0}[/tex]

= 70°

In 2hr : 25 minutes, the distance is:

[tex]\mathbf{= 60+(\dfrac{25}{60})\times 30^0}[/tex]

= 72.5°

Thus, at 2:25, the distance between the tip of the hour hand and the minute will be greater.

Answer: 1,409.737566825

1.785 * 789.768945 = 1,409.737566825

Step-by-step explanation:

Answer:

3x was subtracted from the left side, but 3x was subtracted from the right side. The Subtract Property of Equality states that you can subtract the same number from each side and the equation will remain true. But 3x and 3 are not the same number (unless x is 1).

x = -8/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 12 from both sides.

Step 3: Divide both sides by 10.

9514 1404 393

Answer:

Step-by-step explanation:

You answer this sort of question by comparing each line to the line above to see what the differences are. In the second line, the term 3x is missing from the left side of the equal sign, and the value 5 has been changed to the value 2 on the right side. The wording of the statement you're to fill in tells you that it should read ...

  3x was subtracted from the left side, but 3 was subtracted from the right side.

  ... 3x and 3 are not the same number (unless x is 1 .)

__

The correct solution is ...

  7x +21 +3x = 5 . . . . . . given

  10x +21 = 5 . . . . . . . . . collect terms

  10x = -16 . . . . . . . . . . . subtract 21 from both sides

  x = -1.6 . . . . . . . . . . . .  divide both sides by 10

Additional comment

It can often work well to "read ahead" when answering a question or series of questions. The later questions or comments often provide clues that help you understand how to answer the earlier questions.

Here, for example, it becomes clear that 3x and 3 were subtracted from the different sides of the equation. You can find that out simply by reading the rest of the statement you're to fill in. These are the answers to the questions asked in the first part of the statement.

Answer:

y = 4x + 17

Step-by-step explanation:

y = 1 - 1/4x = - 1/4 x + 1 .... slope -1/4

perpendicular line slope = - (1 / (-1/4) = 4

pass (-3,5): (y-5) / (x - -3) = 4

y-5 = 4x + 12

y = 4x + 17

It's not entirely clear to me what you're trying to solve, but it looks like the initial equation is

[tex]\dfrac{a-2}{a+3} -1 = \dfrac3{a+2}[/tex]

First convert each term into a fraction with the same (i.e. the least common) denominator. The first term needs to be multiplied by a + 2; the second term by (a + 3) (a + 2); and the third term by a + 3 :

[tex]\dfrac{a-2}{a+3}\cdot\dfrac{a+2}{a+2} -1\cdot\dfrac{(a+3)(a+2)}{(a+3)(a+2)} = \dfrac3{a+2}\cdot\dfrac{a+3}{a+3} \\\\ \dfrac{(a-2)(a+2)}{(a+3)(a+2)} - \dfrac{(a+3)(a+2)}{(a+3)(a+2)} = \dfrac{3(a+3)}{(a+3)(a+2)}[/tex]

Now that everything has the same denominator, we can combine the fractions into one. Move every term to one side and join the numerators:

[tex]\dfrac{(a-2)(a+2)-(a+3)(a+2)-3(a+3)}{(a+3)(a+2)} = 0[/tex]

Simplify the numerator:

[tex]\dfrac{(a^2-4)-(a^2+5a+6)-(3a+9)}{(a+3)(a+2)} = 0 \\\\ \dfrac{-8a-19}{(a+3)(a+2)} = 0[/tex]

If neither a = -3 nor a = -2, we can ignore the denominator:

[tex]-8a-19 = 0[/tex]

Solve for a :

[tex]-8a = 19 \\\\ \boxed{a = -\dfrac{19}8}[/tex]

Answer:

[tex]\sqrt{4x^2}=2|x|[/tex]

Step-by-step explanation:

We are given the radical [tex]\sqrt{4x^2}[/tex] and we have to simplify it down as much as possible.

We first will have to find out what numbers are inside the square root, we can see that there is a 4 and an [tex]x^2[/tex], of which both can be taken out of the square root by simplification.

The square root of 4 is 2, and the square root of [tex]x^2[/tex] is [tex]x[/tex].

Due to how radicals work, we have to multiply 2 and [tex]x[/tex], but before that, we have to preserve how the radical was beforehand. We know that a radical cannot have a negative radicand, and due to that we must add absolute value to keep the equation's original status the same.

To sum it all up, our answer is [tex]2|x|[/tex], due to us simplifying it down, and applying absolute value to preserve the answer before it was simplified.

Cheers!

Answer:

x = 20

Step-by-step explanation:

I just plugged in the x possibilities until they both matched, and because they are on opposite sides, as in if they were in the same grid they would be right across from each other, they represent the same angle.

You could also set them equal to each other.

As in:

3x + 32 = 5x - 8

This would simplify (after isolating x) to:

40 = 2x

Divide by 2

20 = x

Answer: 1 problem per day

Step-by-step explanation:

m/5 problems completed in 5 days.

substite m with 5 because 5 days

5/5

5/5=1

Therefore Jack solved 1 question per day.

The number of problems Jack solve per day is 4 problems.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Number of days= 5days

Now,

To find how many problems Jack solved per day, we need to divide the total number of problems by the number of days. This is because he solved the same number of problems every day. So, we can write an equation as:

m / 5 = p

where m is the total number of problems and p is the number of problems per day.

To solve for p, we need to multiply both sides of the equation by 5 and get:

p = m

This means that Jack solved m problems per day.

For example, if m = 20, then Jack solved 20 / 5

= 4 problems per day.

Therefore, by algebra the answer will be 4.
