Answer:

  A.  -3

Step-by-step explanation:

The reduced row echelon form* of ...

  [tex]\left[\begin{array}{ccc|c}4&5&-6&2\\-3&-2&7&-15\\-1&4&2&-13\end{array}\right][/tex]

is ...

  [tex]\left[\begin{array}{ccc|c}1&0&0&-3\\0&1&0&-2\\0&0&1&-4\end{array}\right][/tex]

which tells you the value of 'a' is -3.

_____

* Many scientific and/or graphing calculators and web sites can find the reduced row echelon form of a matrix for you. Or, for a single variable (such as 'a'), you can use Cramer's rule. That requires you compute two 3×3 matrix determinants. Again, there are many calculators, apps, and web sites that will make this calculation for you.

  [tex]a=\dfrac{\left|\begin{array}{ccc}2&5&-6\\-15&-2&7\\-13&4&2\end{array}\right| }{\left|\begin{array}{ccc}4&5&-6\\-3&-2&7\\-1&4&2\end{array}\right|}=\dfrac{147}{-49}=-3[/tex]

Answer:

0 and 2π/3

3rd and 4th

Step-by-step explanation:

Answer:

a is D and b is C

Step-by-step explanation:

Slope is always with an x, b is always alone

Hey there!

Please remember that

Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)

Therefore, the slope, m, is 4, and the y-intercept, b, is -5.

Same with the second equation:

y=2/3-x

or

y=x-2/3

here, the y-intercept, b, is 2/3, and the slope, m, is -1.

Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?

That's right, y=2x-7.

Hope everything is clear.

Let me know if you have any other questions!

Answer:

277 591.1 ft³

Step-by-step explanation:

First, use the formula for circumference to solve for the diameter.

Circumference = πd

295.3 = πd

295.3/π = d

94 ft = d

Then, divide the diameter by 2 to find the radius.

r = d/2

r = 94/2

r = 47 ft

Now, use the value of the radius with the given height in the formula for volume of a cylinder.

V = πr²h

V = π(47²)(40)

V = 277 591.1 ft³

Answer:

1) 8/15

Step-by-step explanation:

When dividing by a number, multiply by its reciprocal.

2/5 ÷ 3/4

2/5 × 4/3

8/15

Answer:

Yes.

Step-by-step explanation:

The expression 2y + 6 could be used to denote the tree's height.

A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.

Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years

Expression = 2y + 6

Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.

therefore, an Expression that represents the height of the tree would be 2y + 6.

Answer:

105

Step-by-step explanation:

Assuming A^2 + B^2 = C^2:

C^2 = 4 + 3 = 7

So,

C^2 * 15 = 49(15) = 105

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

Step-by-step explanation:

there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.

Answer:

123 + (456 + 789)

Step-by-step explanation:

since this is an addition problem, the parenthesis don't matter, and they can be put wherever you want.

(123 + 456) + 789

123 + 456 + 789

(123 + 456 + 789)

123 + (456 + 789)

technically, any of these would work, but I think the kind of answer the problem is looking for is;

123 + (456 + 789)

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the larger number = x

Smaller number = y

6x + 7y = 114 ------------(I)

10x - 9y = 66 ------------(II)

Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x

         (1)*9        54x + 63y = 1026

         (II)*7        70x - 63y  =  462    {Now add}

                        124x           = 1488   {Divide both sides by 124}

                                        x = 1488/124

x = 12

Plugin x =  12 in any of the equation. Here, We are substituting in  equation (I)

6*12 + 7y = 114

  72 + 7y =114

         7y = 114 - 72

         7y = 42

          y = 42/7

y = 6

The numbers are 12 , 6

Answer:

0.3024

Step-by-step explanation:

Given the following :

Probability of breaking pinata on first hit = 0.58;

P(first hit break) = 0.58

P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42

P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72

Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

P(does not break on first hit) * p(2nd hit break)

0.42 * 0.72 = 0.3024

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.
