What number must you add to complete the square? x2 + 10x = 37

1 answer:

8 0

Take 1/2 of x coeficient and square it
10/2=5
5^2=25
you has to add 25 to both sides to complete the square
(x+5)^2=25+37

Find the whole quantity if 5 percent of it is 500

liq [111]

Answer:

10,000

Step-by-step explanation:

500/0.05= 10,000

You take the amount you are given divided by the decimal form of the percentage you are given to find the answer. It's a reverse from the way you find 5% of 10,000.

0.05=5%

Check your work: 10,000*5%= 500

What is the equation in slope-intercept form of the line that passes through the points(-4,2) and (12,6)?

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

Slope intercept form is y = mx + b

First find the slope or m with this equation $\frac{y2 - y1}{x2 - x1}$ (plug in) $\frac{6 - 2}{12 + 4}$ = $\frac{4}{16}$ = $\frac{1}{4}$

So your slope is $\frac{1}{4}$

To find the y-intercept you use y= mx + b and plug in.

6 = 1/4(12) + b

6 = 3 + b (minus 3 on both sides)

3 = b

so 3 is the y-intercept

So the answer is A.

Use the formula for the difference of cubes to show that 125 - 27 = 98

IrinaVladis [17]

The formula is

a^3 - b^2 = (a - b)(a^2 + ab + b^2) so plugging in the given values:-

a = cube root of 125 = 5 and b = cube root of 27 = 3 , we get:-

125 - 27 = (5 - 3)(5^2 + 5*3 + 3^2)

= 2 * 49

= 98 answer
