Answer:

z=8

Step-by-step explanation:

Answer:

z = 8

Step-by-step explanation:

Given

- 9z - 7 = - 23 - 7z ( add 9z to both sides )

- 2z - 7 = - 23 ( add 7 to both sides )

- 2z = - 16 ( divide both sides by - 2 )

z = 8

Answer:

Growth rate is -0.25

Growth factor is 0.75

Step-by-step explanation:

The general form of an exponential equation is;

y = a(1 + r)^x

Where a is the initial value

r is the growth rate

For x = 3; we have

168.75 = 400(1 + r)^3 •••• (i)

For x = 2, we have

225 = 400(1 + r)^2 •••••(ii)

Divide i by ii

That will be;

168.75/225 = 1 + r

1 + r = 0.75

r = 0.75-1

r = -0.25

The growth rate is -0.25

The growth factor is 1-0.25 = 0.75

Step-by-step explanation:

Solution in y-intercept form y=mx+b

We can calculate the slope of the line using any 2 of the given points: I pick (0,3) and (3,9) . Recall the formula for finding the slope of the line through 2 points (x1,y1) and (x2,y2) as m=(y2-y1)/(x2-x1)

By plugging in the corresponding values, we get (9-3)/(3-0)=6/3=2

Since we now the value of y when x is zero, i.e. the point (0,3) of the table, then the value of b is 3.

Now, putting everything together, we have y=2x+3

Solution in point-slope form y-y1=m(x-x1)

You can proceed the same way above to find the slope m=2

Now use one of the points in the given table to plug into x1 and y1

Doing the last 2 steps will result in y-23=2(x-10) if you use the point (10,23)

Realize that the point slope form of the equation of a line is not unique since using a different point will result in different values of x1 and y1. So the answer is A

Answer:5) x=y=7×6^1/2,6)x=38,y=19×3^1/2

7)m=n=18,8)u= 2×5^1/2,v=3

Step-by-step explanation: use trigonometry laws

The value of x=10 and m∠SOP=50° and m∠ROQ=50°  .

When two straight lines intersect each other at a point then vertical angles are formed , there are two pair of vertically opposite angles and also , the vertically opposite angles are equal.

In the given question

m∠SOP = (5x)°      ...(i)

and

m∠ROQ = (4x+10)°    ...(ii)

and Since the angles m∠SOP  and m∠ROQ are vertically opposite , they will be equal .

On equating we get  ,

m∠SOP=m∠ROQ

Substituting the values  from equation (i) and (ii) we get ,

5x=4x+10

5x-4x=10

x=10.

Substituting the value of x in equation (i) we get ,

m∠SOP = (5*10)° = 50°

Substituting the value of x in equation (ii) we get ,

m∠ROQ = (4*10+10)° = (40+10)° = 50°

Therefore , the value of x=10 and m∠SOP=50° and m∠ROQ=50°  .

Answer:

14

Step-by-step explanation:

Range is, basically, the span of all y-values.

To find range, you take the highest y-value and subtract from it the lowest y-value.

Here the highest "y" is 7 and the lowest is -7, so the range is 14.

Answer:

y= -2/7 +5

Step-by-step explanation:

The equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.

Given that, slope (m) =-2/7 and y-intercept (c) =5.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The standard form of the slope intercept form is y=mx+c.

Put m=-2/7 and c=5 in y=mx+c, we get

y=-2/7 x+5

Therefore, the equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.

Answer:

x = 0.8

Step-by-step explanation:

We are given this equation:
4x+8=7.2+5x

And we want to solve it for x.

To solve equations, we need to isolate the variable (x) on one side, and the numbers on the other side.

First, we can clear the numbers from the right side by subtracting 7.2 from both sides.

4x + 8 = 7.2 + 5x

     -7.2  -7.2

_______________

4x + 0.8 = 5x

Now, we can subtract 4x from both sides.

4x + 0.8 = 5x

-4x             -4x

_______________

0.8 = x

This can be rewritten to be: x = 0.8

The value of x is 0.8

Answer:

x=3,y= -4

Step-by-step explanation:

ii) x-2y=11

x=11+2y-----(i)

Now,

i) -7x-2y= -13

or, -7(11+2y)-2y= -13

or, -77-14y-2y = -13

or -14y-2y = -13+77

or -16y = 64

or y =64÷(-16)

:: y = -4

Again,

(ii) x-2y= 11

or x-2(-4)= 11

or x+8 = 11
