Answer:

Step-by-step explanation:

One

The input is the top line. B is the output when multiplied by 4

B = 4A

Input        A       12        15       47        34

Output     B       48       60    188       136

Rule: 12 * 4 = 48;       15*4 = 60  

Check the other two.

Two

B = A/2

Input       A         44         56        18          26           20

Output    B          22        28         9           13            10

Answer:

Pythagorean theorem: a^2 + b^2 = c^2

c is always the hypotenuse (longest side of the triangle)

Plug the numbers in:

17^2 + ?^2 = 19^2

?^2 = 19^2 - 17^2

?^2 = 361 - 289

?^2 = 72

? = 8.48528137424

i hope this helps :)

Answer:

-5 + 8 + 9 = 12

Step-by-step explanation:

To get this, all you have to do is solve the equation.

-5 + 8 = 3

3 + 9 = 12

So, the answer is 12.

Hope this helps! :)

Answer:

The value of a is 6 and the value of b is -12

Step-by-step explanation:

Given identity is:

a(4x – 10) = 24x + 5b

We can use the comparison of coefficients method to find the values of a and b

So,

By simplifying the left hand side of identity

[tex]4ax-10a = 24x+5b\\4ax+(-10)a = 24x+5b[/tex]

Comparing the co-efficient of x

[tex]4a = 24\\a = \frac{24}{4}\\a = 6[/tex]

Comparing the constant terms

[tex]-10a = 5b[/tex]

Putting the value of a

[tex]-10(6) = 5b\\-60 = 5b\\b = \frac{-60}{5}\\b = -12[/tex]

Hence,

The value of a is 6 and the value of b is -12

Answer:

0.833 feets

Step-by-step explanation:

Given that:

Volume of box = 1600

Heigh of box (H) = 8 inches

Let:

Width of box (W) = x

Length of box (L) = 2x

Volume of box = (Height * width * length)

1600 = (8 * x * 2x)

1600 = 16x²

x² = 1600/16

x² = 100

x = sqrt(100)

x = 10 inches

Hence, width of box in feet:

1 inch = 0.0833 feets

10 inches = (10 * 0.0833) feets

= 0.833 feets

Answer:

The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;

p = 1, q = 1

Step-by-step explanation:

The given equation are;

2·x² - 4·x + 3 = 2·(x - p)² + q

By expanding the right hand side of the equation, we have;

2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q

2·x² - 4·x + 3  = 2·x² - 4·p·x + 2·p² + q

Comparing the coefficient of x in both equations, gives;

2·x² + (- 4)·x + 3  = 2·x² + (- 4·p)·x + 2·p² + q

-4 = -4·p

∴ p = -4/(-4) = 1

p = 1

Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;

3 = 2·p² + q

Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;

3 = 2 × 1² + q  = 2 + q

∴ q = 3 - 2 = 1

q = 1.

Answer:

the answer would be p= -4

13-3p = -5(3+2p)

13-3p = -15-10p

13 = -15-7p

28 = -7p

p = -4

Answer:

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

The first option

you read the graph from left to right so x is increasing. If you look at y, it's decreasing.

for each y-value that decreases by 0.5, x-values increase by 1

The first option is correct, As the x- value increases by 1, the y-value decreases by 1/2; the x-intercept is -1.

A function is defined as a relation between the set of inputs having exactly one output each.

we can from the graph from left to right is that x is increasing. If you look at y, it's decreasing.

And for each y-value that decreases by 0.5, x-values increase by 1.

Thus, As the x- value increases by 1, the y-value decreases by 1/2 ; the x-intercept is -1.

Answer: 8 1/20 or 8.05.

Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.

Step-by-step explanation:

-1/3 divided by 3/5 = -5/9

-2/9 - -5/9 = 1/3

Answer:

-1/45

Step-by-step explanation:

Rewrite this as:

-2/9 - (-1/5), or -2/9 + 1/5

Here the LCD is (9)(5) = 45.  Rewriting the above expression, we get:

-10/45 + 9/45 = -1/45
