5.1 x 10^-3 – 1.8 x 10^-3
in scientific notation (evaluate)

Answer:

This system of equations has no solutions

Step-by-step explanation:

in the linear equations, if the variable is disappeared, and

Let us solve the question

∵ x = 2y ⇒ (1)

∵ 6y - 3x = 18 ⇒ (2)

→ Substitute x in equation (2) by the value of x in equation (1)

∵ 6y - 3(2y) = 18

∴ 6y - 6y = 18

∴ 0 = 18

→ 0 can not equal 18

∴ Left hand side ≠ Right hand side

→ From the 2nd note above

∴ This system of equations has no solutions

Answer:

5 1/2 hours

Step-by-step explanation:

by a factor of 5 means times 4

6*4=24

22/4=5.5 hours

It will take 88 hours to complete the homework.

Given is that all of the middle school mathletes solve math problems at the same pace. Working together, 6 mathletes complete all of the summer homework in 22 hours.

6 mathletes complete all of the summer homework in 22 hours.

If the number of mathletes increases by a factor of 4, the number of mathletes will be (4 x 6) = 24 mathletes.

We can write -

1 mathlete will complete all of the summer homework in (22/6) hours.

24 mathlete will complete all of the summer homework in (22/6 x 24) hours.

(22/6 x 24)

(22 x 4)

88

Therefore, it will take 88 hours to complete the homework.

Answer:

8.5>d+10

Step 1: Flip the equation.

d+10<8.5

Step 2: Subtract 10 from both sides.

d+10−10<8.5−10

d<−1.5

Answer:

f(-2)

Step-by-step explanation:

Answer:

- 53, - 207, - 7

Step-by-step explanation:

To obtain f(- 2), substitute x = - 2 into f(x), that is

f(- 2) = - 9(- 2)² + 5(- 2) - 7 = - 9(4) - 10 - 7 = - 36 - 10 - 7 = - 53

(b)

Similarly substitute x = 5 into f(x)

f(5) = - 9(5)² + 5(5) - 7 = - 9(25) + 25 - 7 = - 225 + 25 - 7 = - 207

(c)

f(0) = - 9(0)² + 5(0) - 7 = 0 + 0 - 7 = - 7

Answer:

O1: b) linear, proportional

O2: a) linear, non-proportional

O3: c) nonlinear

Step-by-step explanation:

Recall that a proportional function can be drawn as a straight line (linear function) through the origin (0,0).

O1 is a proportional function since it is linear and goes through the origin.

O2 has a y-intercept of y = 5; therefore, it is not proportional because it does not go through the origin (0,0), although it is linear.

O3 resembles a quadratic function, which means it's not a linear function (nonlinear).

Answer:

Jack is evil.

Step-by-step explanation:

Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.

(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)

Answer:

C - 21:28

Step-by-step explanation:

this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.

For C I did this:

Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.

Let's test it out for the numerator now. 21 ÷ 15 = 1.4.

So there's your answer.

Answer:

Slope: -2/3

Y-intercept: (0, 9)

Equation: y = -x + 9

3 blocks away: 6 visits

Step-by-step explanation:

Calculate slope from point (1, 8) to point (3, 7) on the line.

The y-intercept is where the line meets the y-axis.

The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.

Check the point on the line where x = 3.

Hope this helps!

Erica has 14 cards

Step-by-step explanation:

Answer:

1/1

Step-by-step explanation:

Add: 7/10+3/2

11/5-x       =      6/5

Rearrange: 11/5-x to -x+11/5

Subtract 11/5 of both sides

-x=6/5-11/5

to

-x=-1

x=1

1/1 is the fraction form

Answer:

[tex]y = -2x +7[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-3,13)[/tex]

[tex](x_2,y_2) = (6,-5)[/tex]

Required

Determine the equation in slope intercept form

First, we calculate the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

The equation becomes:

[tex]m = \frac{-5 - 13}{6 - (-3)}[/tex]

[tex]m = \frac{-5 - 13}{6 +3}[/tex]

[tex]m = \frac{-18}{9}[/tex]

[tex]m = -2[/tex]

The equation is then calculated using:

[tex]y -y_1 = m(x - x_1)[/tex]

Substitute values for y1, m and x1

[tex]y - 13 = -2(x -(-3))[/tex]

[tex]y - 13 = -2(x +3)[/tex]

[tex]y - 13 = -2x -6[/tex]

Make y the subject

[tex]y = -2x - 6 + 13[/tex]

[tex]y = -2x +7[/tex]

Answer:

252 cubic cm

Step-by-step explanation:

V = (l x w x h ) / 3

V = (6 cm x 9 cm x 14cm) / 3

V = 756/3 =  252 cubic cm

Answer:

252 cubic cm

Step-by-step explanation:

[tex]B_{p}[/tex]=(1/3)Bh

B=l*w

B=6*9=54

h=14

[tex]B_{p}[/tex]=1/3(54)(14)=252 cubic cm

Hey there!

Formula: πr^2

r = radius

pi = 3.1415926535898 (but we can say it approximately equals 3.14)

Your equation (3.14)(4.2)^2 = answer

4.2^2 = 4.2 × 4.2 = 17.64

New equation: 17.64 × 3.14 = 55.3896

We round our answer to the nearest tenth

Answer: 55.4 ☑️
