3 0

Answer:

3,000 words

Step-by-step explanation:

we know that

Emilio cay type 850 words in 17 minutes

Remember that

1\ h=60\ min

so

using proportion

Find out how many words can Emilio type in 60 minutes (one hour)

Let

x ---> the number of words

\frac{850}{17}\ \frac{words}{minutes} =\frac{x}{60}\ \frac{words}{minutes}\\\\x=60(850)/17\\\\x= 3,000\ words

Find two numbers whose product is -2, and whose sum is -1.​
PIT_PIT [208]

Answer:

x=-2  \ \ \ and \ \ \  y=1

Step-by-step explanation:

Suppose numbers are <em>x</em> and <em>y</em>

<u>Product of </u><em><u>x</u></em><u> and </u><em><u>y</u></em><u> is </u><em><u>-2</u></em>

<u />xy=-2

And sum of <em>x</em> and <em>y</em> is <em>-1</em>

x+y=-1

x=-2  \ \ \ and \ \ \  y=1

Angle <QAB is =15° because the opposite angles of an isosceles triangle are equal.

The length of the straight line AB = 80cm

<h3>Calculation of angle of a triangle</h3>

The angle at a point = 360°

Angle AQB= 360 - 210° = 150

But the angle that makes up a triangle= 180°

180-150= 30°

But <QAB = <QBA because triangle AQB is an isosceles triangle.

30/2 = 15°

To calculate the length of the straight line the following is carried out using the sine laws.

a/ sina, = b sinb

a= 8cm, sin a { sin 15)

b= ? , sin B = 150

make b the subject formula;

8/sin15= b/sin 150

b= 8 × sin 150/sin 15

b= 80cm

What is the domain of the function y = -4x+1 if the range is -11
a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

y=-4x+1

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

x=-\frac{1}{4}(y-1)

If the range of the original function is the set given by the number {
