Answer: B) 3+y+3

This can be simplified to y+6, but the current un-simplified expression has 3 terms.

======================================

Explanation:

Terms are separated by a plus sign. If you had something like 10x-5y, then you would write that as 10x+(-5y) showing that 10x and -5y are the two terms.

Choices A and C, xy and 6y respectively, have one term each. They are considered monomials. Mono = one, nomial = name.

Choice D is the product of the constant 3 and the binomial y+3. Binomials have two terms.

Only choice B has three terms, though we can simplify it down to two terms. I have a feeling your teacher doesn't want you to simplify it.

Y= mx + b what is b?

PSYCHO15rus [73]

Y=mx+b is Slope Intercept Form, where m represents the slope and b represents the y-intercept.

The y-intercept is the value of y when x equals 0, and can be visualized on a graph as the point on the line when it crosses the y-axis.

The picture is the answer i forgot it last time

C is your answer

because (4, -6) is true, and it lies on both lines, which makes both equations true

hope this helps

We know that the true value for pi is given as 3.14156.

Now, we have been given that the approximate value for pi is 3.141

We know the formula

Absolute error, $\Delta x = | \text{True value } - \text{ Approximate value} | \\
\\
\Delta x =|3.14156-3.141|\\
\\
\Delta x =0.00056$

Relative error is given by

$\text{Relative error }= \frac{\Delta x}{\text{true value} }\\
\\
\text{Relative error }=\frac{0.00056}{3.14156} \\
\\
[tex]\text{Relative error }=0.000178$

The percentage error is given by

$\text{Relative error } \times 100\\ 
\\ 
0.000178\times 100 
\\ 
=0.0178 \%$

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5

Leto [7]

Answer:

y = $-\frac{1}{2}$ x + 9

Step-by-step explanation:

Given parameters:

Coordinates = (-2,8)

Equation of the line y = 2x + 5;

Unknown:

Linear equation of a line perpendicular = ?

Solution:

From the given expression, a line perpendicular will have a negative inverse of the slope given.

y = 2x + 5

Equation of a line is y = mx + c;

y and x are the coordinates

m is the slope

c is the intercepts

y = 2x + 5 ;

The slope is 2;

A line perpendicular will have a slope of $-\frac{1}{2}$

Since y = 8 and x = -2, let us find c;

8 = 2 x $-\frac{1}{2}$ + c

8 = -1 + c

c = 8+1 = 9

The equation of the line is;

y = $-\frac{1}{2}$ x + 9
