Answer:

y = 10x + 30

x = 12

Step-by-step explanation:

The slope-intercept form formula, y = mx + b, can be used to write an equation for the line.

Where,

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

b = y-intercept, which is the point at which the line intercepts the y-axis. At this point, x = 0.

Let's find the slope (m) using the coordinates of the two points given, (0, 30), (3, 60).

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

Let,

(0, 30) = (x_1, y_1)

(3, 60) = (x_2, y_2)

m = \frac{60 - 30}{3 - 0}

m = \frac{30}{3}

m = 10

y-intercept of the line, b = 30

Equation for the line would be:

y = 10x + 30

Using the equation, find x when y = 150.

Simply substitute the value for y in the equation to find x.

150 = 10x + 30

Subtract 30 from both sides

150 - 30 = 10x + 30 - 30

120 = 10x

Divide both sides by 10

\frac{120}{10} = \frac{10x}{10}

12 = x

x = 12

Find the smallest square number that is divisible by each of the numbers 8, 9 and 10
vekshin1

Answer:

Step-by-step explanation:

Find the LCM of 8,9 and 10.

Prime Factorization to find LCM,

8 = 2 × 2 × 2

9 = 3 × 3

10 = 2 × 5

LCM ( 8 , 9 , 10 ) = 2 × 2 × 2 × 3 × 3 × 5 =360

But 360 is not square

Now we make the pairs complete by multiplying same numbers in prime factorization of LCM.

We need one 2 and one 5 to complete the pair.

We get, Least Square number = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 3600

Hope this helps

good Luck

Kryger [21]

Answer:

The answer is below

Step-by-step explanation:

The equation of a linear function is given as:

y = mx + b;

where y, x are variables, m is the rate of change and b is the initial value of variable y.

A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:

T = 25h + B

B) Given that B = 5, h = 6, hence:

T = 25(6) + 5 = 150 + 5 = 155 bacteria

C) The equation of the graph is:

T = 25h + 5

The graph was plotted using geogebra online graphing.
