Answer:

-9

Step-by-step explanation:

In synthetic division we are multiplying the number -1 with the number written at the last line.

So here first we multiplied -1 with 3 to get -3, write it down below -4.

Now when we add -4 and -3 we get -7.

Again we multiply -1 with -7 , to get 7, writing it down below 2.

Then we add 2 and 7 to get 9.

Again we multiply -1 with 9 , that will give us -9.

So we write -9 below -1 in last column to get -10.

So the missing number is -9.

Answer:

15 165

Step-by-step explanation:

m1 + m2 = 180

x-18 +5x = 180

6x = 198

x = 33

m1 = 15

m2 = 165

Write the equation of a line that meets all the following requirements:
LuckyWell [14K]

9514 1404 393

Answer:

  • x + y = 5
  • y = -x + 5

Step-by-step explanation:

We can start with the point-slope form of the equation for a line. To meet the given requirements, we can use a point of (5, 0) and a slope of -1. Then the equation in that form is ...

  y -0 = -1(x -5)

Simplifying gives the slope-intercept form:

  y = -x +5 . . . . . . . use the distributive property to eliminate parentheses

Adding x to both sides gives the standard form:

  x + y = 5

__

<em>Explanation</em>

We know the line has the required intercept and slope because we chose those values to put into the point-slope form. Conversion from one form to another made use of the rules of equality, the additive identity element (y-0=y), and the distributive property.

A kite on a 100-foot string is fastened to the ground, making a 25° angle with the ground. To the nearest tenth of a foot, how h
lozanna [386]

Answer:  42.3 ft

<u>Step-by-step explanation:</u>

Draw a picture (see attachment)

Given: angle = 25°, hypotenuse = 100, opposite = ???

\sin\theta=\dfrac{opposite}{hypotenuse}\quad \rightarrow \quad \sin25^o=\dfrac{y}{100}\quad \rightarrow \quad 100\ \sin 25^o=y\\

                                                                            \large\boxed{42.3\ ft}=y

Please help I asked this question earlier and nobody answered! :(​
tatiyna

Answer:

B

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form.  That form is usually written y=mx+b where  <em>m</em>  is the slope and  <em>b</em>  is the y-intercept.

Solve the first equation for y.

6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

y+3x=2\\y=-3x+2

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and <u>different</u> y-intercepts.  There is no solution to the system.
