Answer:

1st box: 1

2nd box: 1

Step-by-step explanation:

1: 3 * 7 = 21, so only put the 1 and carry the 2.

2: 5 * 6 = 30, but we have a 1 from the previous answer given so 31, but only put the 1.

I hope this helps :)

Answer:

Step-by-step explanation:

Original equation

    √x+6-4 = x

   Isolate

    √x+6 = 4+x

Raise both sides to the second power

    (√x+6)2 = (4+x)2

    After squaring

    x+6 = x2+8x+16

Rearranged equation

    x2  + 7x  + 10 = 0

    This equation has two rational roots:

      {x1, x2}={-2, -5}

Original equation, root isolated

    √x+6 = 4+x

    Plug in  -2 for  x  

     √(-2)+6 = 4+(-2)

     Simplify

     √4 = 2

     Solution checks !!

    Solution is:

     x =  -2

Original equation, root isolated

    √x+6 = 4+x

    Plug in  -5 for  x  

     √(-5)+6 = 4+(-5)

     Simplify

     √1 = -1

     Solution does not check

     1 ≠ -1  

The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).

The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].

The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].

Overall, this function has a domain of

[-4, 1) U [-1, 2] U (2, 5]

(where U means "union" in the set-theoretic notion)

But this also simplifies to the interval [-4, 5].

These correspond to the first and last choices.

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

7×3 -4(225÷32)×2

7×3 -4(7.03)×2

21 - 8 (7.03)

21 - 56.25

= - 35.25

A (3)(-17.25) = -51.75

This is the answer because Paul took 17.25 from his saving every week, so that would make 17.25 negative in the equation. 3 is just the number of weeks, there is no need for a negative there.

If Horizontal- 2,3,4

If Vertical- 4,5

Answer:

x = 20

y = 26

Step-by-step explanation:

40 and 2x are vertical angles, so they're equal to each other.

40 = 2x

Divide both sides by 2

x = 20

We see that 40 and 5y + 10 are a linear pair, which means they add up to 180.

5y + 10 + 40 = 180

5y + 50 = 180

5y = 130

y = 26

Answer:

6x² + 15

6

Step-by-step explanation:

Let the number be x.

"the square of a number"

x²

"the product of 6 and the square of a number"

6x²

"the product of 6 and the square of a number plus 15"

6x² + 15

The coefficient is the number that multiplies the variable, so it is 6.

The expression that can represent the given statement is 6x²+15, while the value of the coefficient is equal to 6.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let the unknown number be represented by x. Therefore, the given statement can be broken down and written as shown below,

1. "the product of 6 and the square of a number"

        6x²

2. "the product of 6 and the square of a number plus 15"

        6x² + 15

Thus, the expression that can represent the given statement is 6x²+15.

Now, the coefficient of the expression is the number that is in multiplication with the unknown variable, therefore, x in this case. Thus, the value of the coefficient is 6.

Hence, the expression that can represent the given statement is 6x²+15, while the value of the coefficient is equal to 6.

Answer: four blows of hammer

Step-by-step explanation:

The first blow of hammer drove the 3cm nail into wood by 1.25cm leaving 1.75cm of the nail

3/5 or 0.6cm of the nail was also driven into wood by the second blow of hammer leaving 0.7cm of the nail

The third is also drove 0.6cm of the nail in leaving 0.1cm

since 0.1cm is not up to 0.7cm,it will definitely be driven in completely by the fourth blow of hammer.

Answer:

Sand: 21 parts.

Lime : 14 parts.

Cement: 7 parts.

Step-by-step explanation:

The number of parts is 3 + 2 + 1 = 6.

So for 42 parts we need:

Sand: 3/6 * 42 = 1/2 * 42 = 21.

Lime:  2/6 * 42 = 1/3 * 42 = 14,

Cement: 1/6 * 42 = 7.

Step-by-step explanation:

Let's find the distance between your two points.

D=√(x2−x1[tex])^{2}[/tex]+(y2−y1[tex])^{2}[/tex]

Answer:

y = -2

Step-by-step explanation:

3(y-2)=2y-8

3y - 6 = 2y - 8

y - 6 = -8

y = -2

Answer:

See Below.

Step-by-step explanation:

By definition, if two functions, f and g, are inverses, then:

[tex]\displaystyle f(g(x)) = g(f(x)) = x[/tex]

We are given the two functions:

[tex]\displaystyle g(x) = \sqrt{x + 8} -4 \text{ and } f(x) = x^2 + 8x + 8[/tex]

Find f(g(x)) and g(f(x)):

[tex]\displaystyle \begin{aligned} f(g(x)) &= (\sqrt{x + 8} -4)^2 + 8(\sqrt{ x+ 8}-4) + 8 \\ \\ &= ((x+8) -8\sqrt{x + 8} +16) + 8\sqrt{x + 8} - 32 + 8 \\ \\ &= x + (-8\sqrt{x+8} + 8\sqrt{x + 8}) +(16 - 32 + 8 + 8) \\ \\ &= x \stackrel{\checkmark}{=} x\end{aligned}[/tex]

And:

[tex]\displaystyle \begin{aligned}g(f(x)) &= \sqrt{(x^2 + 8x + 8) + 8} - 4 \\ \\ &= \sqrt{x^2 + 8x+16 } - 4 \\ \\ &=\sqrt{(x+ 4)^2} - 4 \\ \\ &= (x +4) - 4 \\ \\ &= x \stackrel{\checkmark}{=} x \end{aligned}[/tex]

Hence, f and g are indeed inverses of each other.
