M= 6 so 2m would be 12 and 12-3=9

Answer:

Step-by-step explanation:

First, you solve the initial equation 3m+5=23.

3m+5-5=23-5

3m=18

3m/3=18/3

m=6

Second, you input the answer 6 into m in the second equation.

2(6)-3

12-3

replace the value of x int eh equation

so 23x-1 becomes

23(1.1478)-1

23*1.1478 = 26.3994-1 = 25.3994

If you knew that the vertical intercept for a straight line was 150 and that the slope of the line was 4, then the dependent var

Maslowich

Answer:

Value of the independent variable = 25

Step-by-step explanation:

y-intercept form of a straight line is represented by the equation,

y = mx + b

here y = dependent variable

m = slope

b = y intercept or vertical intercept

x = independent variable

In our question,

y-intercept 'b' = 150

slope of the line 'm' = 4

dependent variable y = 250

We will plug in these values in the equation of the line to get the value of the independent variable.

250 = 4x + 150

250 - 150 = 4x

x = $\frac{100}{4}$

x = 25

Therefore, value of the independent variable is 25.

For the experimental probability you must record the data that you collect by flipping your own coin, then you must find the probability of landing on either side. For example, the theoretical probability for the coin toss it will be 50% chance for either side. For the experimental it depends on your own results.

$HEY MATE !!$

Secx = $\frac{25}{24}$

As we know secx = hypotenuse/ perpendicular

And cotx = Base / perpendicular

So now we have to find BASE .

${25}^{2}= {B}^{2}+ {24}^{2}$
625= ${B}^{2}$ + 576
${B}^{2}$ = 625 - 576
${B}^{2}$ = 49

Taking squre root on both sides.

B = 7

Now cotx = 24/ 7

SO YOUR ANSWER IS OPTION . (C)

HOPE YOU LIKED.
