Answer: I think the coefficient is -x

Step-by-step explanation:

A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.

The expression is -x-10. If we go back to the definition, the coefficient combined to the variable is -1.

A variable like the 'x' in this expression can also be written as 1x.

So the answer is -1.

Hope it helps!

Answer:

4

Step-by-step explanation:

If you have 2 lines inter secting you have 4 corners. All these corners are congruent(they are the same). This means if one is 90 they all are 90.

Answer: x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(−2x−4)−2x+2=−42

(5)(−2x)+(5)(−4)+−2x+2=−42(Distribute)

−10x+−20+−2x+2=−42

(−10x+−2x)+(−20+2)=−42(Combine Like Terms)

−12x+−18=−42

−12x−18=−42

Step 2: Add 18 to both sides.

−12x−18+18=−42+18

−12x=−24

Step 3: Divide both sides by -12.

-12x/-12=-24/-12

Answer:

0.04

Step-by-step explanation:

We know that 4% of packages are lost in the mail, but we want to know the decimal.

We must convert 4% to a decimal. There are 2 ways to do this.

1.

Remove percent sign and divide by 100.

4%

4

4/100

0.04

2.

Remove percent sign and move decimal place two spots to the left.

4%

4 = 4.0

4.0  -->  0.4  --> 0.04

0.04 of the packages are lost in the mail.

Answer:

[tex]\frac{48}{49}[/tex]

Step-by-step explanation:

(3/7÷1/2) ÷ 7/8​

[tex](\frac{3}{7} : \frac{1}{2} ) : \frac{7}{8} \\\frac{6}{7} : \frac{7}{8} \\\frac{48}{49}[/tex]

Answer:

12.

Step-by-step explanation:

This equation seems to want you to use the Order of Operations, a.k.a PEMDAS (which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). When you do a problem like this, you use the Order of Operations to figure out the order in which you'd solve your problem.

You would first solve what is in parentheses, since that is the first letter in PEMDAS. 18-6x2 is what we have in our parentheses, but it's too confusing to be solved yet. The next letter is E, a.k.a exponents, but there are no exponents in this equation, so we move on. Next is M, Multiplication. We would multiply 6 by 2, which gives us 12. Moving on, we have D, Division. We would do 36/6, which is 6.

Our 5th letter is A, Addition. We would have to add our 6 to (18-12), but that couldn't work, since our 18-12 is still in parentheses, and those come first. So, we would skip to the last letter, S, Subtraction. 18-12=6, and since we solved all the problems in the parentheses, we remove them, and add both 6's together, giving us 12.

No, the piecewise graph is NOT a function because it does NOT pass the vertical line test.

The vertical line test is where we try to pass a line through more than one point on the curve. If it is not possible to do this, then the graph is said to "pass the vertical line test".

In this case, the given graph fails the vertical line test. Look at something like x = -2. We can draw a vertical line through here to pass through more than one point. One point is on the upside-down V shape, and the other point is on the parabolic shape. Plugging x = -2 into this leads to more than one y outputs.

A function is only possible if any valid x input (from the domain) leads to exactly one output y value (in the range).

Answer:

[tex] \frac{3}{4} [/tex]

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

[tex] f(0) = 0 [/tex] (when x = 0, y = 0)

[tex] f(4) = 3 [/tex] (when x = 4, y = 3)

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

[tex] a = 0, f(a) = 0 [/tex]

[tex] b = 4, f(b) = 3 [/tex]

Plug in the values into the formula for average rate of change.

[tex] = \frac{3 - 0}{4 - 0} [/tex]

[tex] = \frac{3}{4} [/tex]

Average rate of change [tex] = \frac{3}{4} [/tex]

Answer:

Equation is [tex]8M + 7P = 131[/tex]

[tex]M = \$12[/tex]

Step-by-step explanation:

Given

Jason: 6 Movies and 4 popcorn

Michael: 2 Movies and 3 Popcorn

1 Popcorn = $5

Total = $131

Required

- Write an equation to solve

Represent Movie with M and Popcorn with P

For Jason, we have:

6M + 4P

For Michael, we have:

2M + 3P

Add these parameters together

Jason + Michael = $131

[tex]6M + 4P + 2M + 3P = 131[/tex]

Collect Like Terms

[tex]6M + 2M+ 4P + 3P = 131[/tex]

[tex]8M + 7P = 131[/tex]

Hence the equation is [tex]8M + 7P = 131[/tex]

From the question, we have that

[tex]P = \$5[/tex]

Substitute 5 for P

[tex]8M + 7 * 5 = 131[/tex]

[tex]8M + 35 = 131[/tex]

Solve for M

[tex]8M = 131 -35[/tex]

[tex]8M = 96[/tex]

[tex]M = \frac{96}{8}[/tex]

[tex]M = \$12[/tex]

Answer:

A is spanned by vector.

Step-by-step explanation:

The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.

Answer:

52:49

Step-by-step explanation:

pink:green

The ratio of pink to green marbles is

3k:4k

He removes 5 green marbles and adds 8 pink marbles.

Now the ratio of pink to green marbles is

(3k + 8):(4k - 5)

This rario is equal to 29:23.

(3k + 8)/(4k - 5) = 29/23

29(4k - 5) = 23(3k + 8)

116k - 145 = 69k + 184

47k = 329

k = 7

Original amounts:

3 * k = 3 * 7 = 21 pink

4 * k = 4 * 7 = 28 green

Original total = 21 + 28 = 49

Amounts after replacement:

3k + 8 = 3(7) + 8 = 29 pink

4k - 5 = 4(7) - 5 = 23 green

Total after replacement = 23 + 29 = 52

Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.
