Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Convert into kilometer 213 km 42 m

Answers

Answer:

213.042  km

Step-by-step explanation:

We need to convert 213 km 42 m to km.

We know that,

1 km = 1000 m

or

1 m = (1/1000)km

So,

42 m = (42/1000) km

It means,

[tex]213\ km\ 42\ m=213\ km+\dfrac{42}{1000}\ km\\\\=213.042\ km[/tex]

So, the required answer is 213.042  km.

area = 44 cm²

Step-by-step explanation:

rectangle area = bh = 8 x 4 = 32 cm²

triangle height² = 5² - 4³ = 25 - 16 = 9

triangle height = 3

triangle area = 1/2bh = 1/2(8)(3) = 12 cm²

32 cm² + 12 cm² = 44 cm²

A.
20 cm
B.
21 cm
C.

D.
10 cm

Answers

Answer:

Step-by-step explanation:

You should start with 10. The problem with 10 is that if you add 4 to it, the sum is less than 15, so no triangle will form.

A and B won't work either 4 + 15 is 19. A and B are both longer than 19 so no triangle will form.

The answer has to be C. 4 and 15 make 19. That's more than 17 so a triangle will be formed.

Which of the expressions have like terms? Select all that apply
A. -6m + 4m
B. t + 6.75t
C. 10m + mn
D. 6 - 6p
E. 9xy - 4xy
F. 2y + 5x

Answers

Answer:

A, B, and E

Step-by-step explanation:

When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.

For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.

What would NOT be like terms?

C-- 10m + mn

This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.

Hope this helps!!

Answer:

  Step 2 is where the error lies.

  The solution is x > 6

Step-by-step explanation:

The rules for solving inequalities are substantially similar to the rules for solving equations. If you perform the same operation on both sides of the comparison, the value of the variable does not change. (The exception is when that operation is an "order-reversing" operation. See comment below.)

Kahal's steps would be expected to be the same ones you would use:

  Step 1: 4x -4 > 20 . . . given

  Step 2: 4x > 24 . . . add 4 to both sides

  Step 3: x > 6 . . . . . divide by 4

We note that our Step 2 is different from Kahal's Step 2. In Step 2 is where his mistake was made. He added 4 to one side and subtracted 4 from the other side.

__

Exception (order-reversing operations)

The operation you will usually run across in high-school algebra that will reverse ordering is multiplication (or division) by a negative number. Consider, for example, ...

  1 < 2

  -1 > -2 . . . . . both sides of the inequality multiplied (or divided) by -1

Notice that the order has been reversed: the larger magnitude number is now "less than".

Slope=5/4 y intercept=2 write in slope intercept form then standard

Answers

Note:

Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.

                                         

Answer:

The equation in the standard form is:

2/3x + y = -4

Please also check the attached graph.

Step-by-step explanation:

We know that the equation in the standard form is

Ax + By = C

where x and y are variables and A, B and C are constants

Given

Slope m = -2/3

y-intercept = -4

To determine

Write the equation in the standard form

We know that the slope-intercept form of the line equation

where

m is the slope

b is the y-intercept

In our case:

Slope m = -2/3

y-intercept = -4

substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation

y = mx+b

y = -2/3x  + (-4)

y = -2/3x - 4

Writing the equation in the standard form

2/3x + y = -4

Therefore, the equation in the standard form is:

2/3x + y = -4
