In 1 hour you'll have 4 cells so multiply that by 3 and you will have 12 cells in 3 hours

Pretest: Unit 5 Question 12 of 21 Use the substitution method to solve the system of equations. Choose the correct ordered pair.

Gala2k [10]

Answer:

(10, - 9 )

Step-by-step explanation:

Given the 2 equations

y = - 2x + 11 → (1)

y = - 3x + 21 → (2)

Substitute y = - 2x + 11 into (2)

- 2x + 11 = - 3x + 21 ( add 3x to both sides )

x + 11 = 21 ( subtract 11 from both sides )

x = 10

Substitute x = 10 into either of the 2 equations and evaluate fir y

Substituting into (1)

y = - 2(10) + 11 = - 20 + 11 = - 9

solution is (10, - 9 )

What is the approximate distance between the points (1,-2) and (-9,3) on a coordinate grid

jeka57 [31]

<u>Answer</u>

$5\sqrt{5}$ ≈ 11.1803398874989485

<u>Detailed Explanation </u>

We will be using the distance formula for this problem

$\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

Now, let's input the numbers into the formula.

$\sqrt{\left(-9-1\right)^2+\left(3-\left(-2\right)\right)^2}$

Solve.

Therefore, the distance between the two points is

$5\sqrt{5}$ ≈ 11.1803398874989485

Find the distance between the two points (-10,3) and (0,27)

crimeas [40]

Answer:

26 units

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above,

distance between (-10, 3) and (0, 27)

$= \sqrt{ {( - 10 - 0)}^{2} + {(3 - 27)}^{2} }$

$= \sqrt{ {10}^{2} + ( - 24) {}^{2} }$

$= \sqrt{100 + 576}$

$= \sqrt{676}$

= 26 units
