Answer:

(-2,10)

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−8x=20

Step 1: Subtract 20 from both sides.

x2−8x−20=20−20

x2−8x−20=0

Step 2: Factor left side of equation.

(x+2)(x−10)=0

Step 3: Set factors equal to 0.

x+2=0 or x−10=0

x=−2 or x=10

Answer:

x=−2 or x=10

Answer:

♡ Hi darling!

~The answer is 800,000.

Here is some explanation on how to round numbers to the nearest hundred thousand easily.

You can just look at the next place value to the right (the thousandths this time). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right. ♡

Hope this helps, have an amazing night/day and remember your loved! Make sure to take care of your mental health and eat food and drink water today.

Answer:

let x be the total amount of gallons he bought

$16.80÷$1.40 = x

16.80÷1.40=12

x=12

Step-by-step explanation:

Complete the square:

2x² + 9x - 18

2(x² + 9/2 x) - 18

2(x² + 9/2 x + 81/16 - 81/16) - 18

2(x² + 2 (9/4) x + (9/4)²) - 81/8 - 18

2(x + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

ax² + bx + c

into its vertex form

a (x - h)² + k

where (h, k) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

a (x² - 2xh + h²) + k

ax² - 2ahx + ah² + k

For the two forms to be equivalent, we must have

-2ah = b

ah² + k = c

which means

h = -b/(2a)

k = c - ah² = c - b²/(4a)

In this case, a = 2, b = 9, and c = -18, so

h = -9/(2 • 2) = -9/4

k = 18 - 9²/(4 • 2) = -225/8

Answer:

About 158 times

Step-by-step explanation:

Represent the rate of human heart with H and sparrow's heart with S

[tex]H = 1,533,000\ times[/tex]

[tex]S = 241,776,000\ times[/tex]

Required

Determine how many times faster is S than H

To do this, we simply divide S by H i.e.

[tex]Number = \frac{S}{H}[/tex]

[tex]Number = \frac{241,776,000}{1,533,000}[/tex]

[tex]Number = 157.714285714[/tex]

[tex]Number = 158[/tex] --- approximated

Hence, the sparrow's heart beats about 158 times faster than the human hearts

Answer:

Slope: 6

Y-intercept: 4

Equation: y=6x+4

Step-by-step explanation:

For slope you do change in y over change in x so its 10-4/1-0 in this case which gets you 6/1 or 6 for your slope

It crosses the y-axis at (0,4) so your y-intercept is 4

The base equation is y=mx+b m is slope b is y-intercept so you plug in your values and get y=6x+4

Step-by-step explanation:

Answer:C 4x-y=2

Step-by-step explanation:

The equation of the line that has a slope of 4 is 4x - y = 10.

Option D is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = 4.

The line contains (3, 2).

The equation of the line.

y = mx + c

m = 4

(3, 2) = (x, y)

2 = 4 x 3 + c

2 = 12 + c

c = 2 - 12

c = -10

Now,

y = 4x - 10

4x - y = 10

Thus,

The equation of the line is 4x - y = 10.

Answer:

-9n+8

Step-by-step explanation:

Answer:

Step-by-step explanation:

we are given that 1 angle equals 27 and the other two are equal.

180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
