One number is 6 more than anouther number. the sum of their squares is 90
Flura [38]
Let x = greater number
      y = smaller  number

(1) x = y + 6

(1) y = x-6

(2) x^{2} + y^{2} = 90
We'll substitute y in (1) to (2)
(2) x^{2} +  (x-6)^{2} = 90
     x^{2} +  (x^{2} - 12x + 36) = 90
     x^2 + x^2 -12x + 36 - 90 = 0
     2x^2 - 12x -54 = 0

     2(x^2 - 6x - 27) = 0
     2(x - 9)(x + 3) = 0
 x - 9 = 0        or      x + 3 = 0
      x = 9                        x = -3
and
 y = x - 6                  y = x - 6
 y = 9 - 6                  y = -3 - 6
 y = 3                        y = -9

Therefore, the two numbers can be 9 and 3 or -3 and -9.

Domain: All real values (numbers)

Range: all real values that are less than or equal to 4. y\leq 4

Zeros: x=-2 and x=2 or if you want to write it in an ordered pair, it is (-2,0) and (2,0).

Vertex: (0,4)

Min/Max: 4. or if you want to write in an ordered pair (0,4). In this case, it is a maximum value.

Axis of symmetry: x=0

y-intercept: (0,4)

Which is the equation of the given line? (-10,-7) (3,-7)
Vladimir [108]

Answer:  y=-7

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

m=\frac{y_2-y_1}{x_2-x_1}

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0

Substitute the slope and any point into  y=mx+b and solve for "b":

-7=0x+b\\b=-7

Then, substituting "m" and "b" into the equation  y=mx+b, you get that the equation of this line is:

 y=0x-7

 y=-7

The value of the digit in the hundreths place is how many times as much as the value of the digit in the tenths place. 0.44
Rus_ich [418]

Answer:

Given number = 0.44

Find how many times the value of the hundredths place digit to the value of the tenths place digit.

=> Since this is a decimal number, I believe, the value you mean is tenths and hundredths, not tens and hundreds.

Now, how many times is the value of each digit differs from each other:

The answer is 10 times

=> 4 hundredths x 10 = 4 tenths

=> 0.04 x 10 = 0.4, which is correct

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manag
il63 [147K]
Since 2 cases = $48

÷ 48 by 2 to get the cost of one case of paper

48÷2=$24 per case
and each case has 12 pack of paper

so $24 for 12 packs of paper

180÷12=15, which gives you the number of case you need

15 cases × $24= $360 for 180 packs
