2/5m - 4 + = 16 + is what?

Mathematics

1 answer:

asambeis [7]3 years ago

8 0

Answer:

2/5m-4=16

We move all terms to the left:

2/5m-4-(16)=0

Domain of the equation: 5m!=0

m!=0/5

m!=0

m∈R

We add all the numbers together, and all the variables

2/5m-20=0

We multiply all the terms by the denominator

-20*5m+2=0

Wy multiply elements

-100m+2=0

We move all terms containing m to the left, all other terms to the right

-100m=-2

m=-2/-100

m=1/50

No because the first nine means 9,000,000 (nine million)and the last nine means just 9 meaning the first"nine's" value is a lot greater

-2 1/4 divided by (-1 1/2) =

Diano4ka-milaya [45]

Answer:

9/22

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

−9/4 ÷ −11/2

Applying the fractions formula for division,

=−9×2 divided by 4×−11

=−18/−44

Simplifying -18/-44, the answer is

=9/22

Explain how the words term and coefficient are used in talking about the algebraic expression.

cupoosta [38]

<h2>Answer:</h2>

The algebraic expressions are composed of several elements: Terms, Coefficients, Signs, Variables and Exponents. In this case we will focus on the first two.

The terms are composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).

For example, in the following expression:

2x-3x

We have two terms separated by the negative sign (-):

2x is the first term

-3x is the second term

Now, the coefficients are the numbers that multiply the variable. Note that if this coefficient is one (1) it is omitted .

For example in the following expression, the variable is x:

2x-3x+x

2 is the coefficient of x in the first term

-3 is the coefficient of x in the second term

1 is the coefficient of x in the third term, but is omitted

In order to understand this in a better way, see the figure attached, where the algebraic expression is composed by one term.

How do i find the x intercet for y=6x−7.

kolezko [41]

Answer:

Step-by-step explanation:

y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-6x+7 = 0 and calculate its properties.

Graph of a Straight Line

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is -7/1 so this line "cuts" the y axis at y=-7.00000

y-intercept = -7/1 = -7.00000

Calculate the X-Intercept :

When y = 0 the value of x is 7/6 Our line therefore "cuts" the x axis at x= 1.16667

x-intercept = 7/6 = 1.16667

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -7.000 and for x=2.000, the value of y is 5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.000 - (-7.000) = 12.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 12.000/2.000 = 6.000

x-intercept = 7/6 = 1.16667

y-intercept = -7/1 = -7.00000
