Find the values of x and y if (x+2,y)=(3,4).

Answers

Answer:

x = 1 and y = 4

Step-by-step explanation:

Solution,

(x+2,y) = (3,4)

Now,

Comparing corresponding elements,

x+2 = 3 , y = 4

or, x = 3 - 2 , y = 4

or, x = 1 , y = 4

Therefore, the value of x is 1 and y is 4.

Helen is merging images from her two favorite movies so that the characters from the different movies appear to be dueling with each other. The editing program she is using has a virtual protractor, which tells Helen that the character in the first picture is holding her sword at a 43 angle and that the character in the second picture is holding his sword at a 107 angle. In the merged image that Helen creates, what will the angle between the characters’ swords be?

Answers

Answer:

[tex]the \: angle \: between \: the \: characters’ \: swords\: \\will \: be \: 30[/tex]

find the distance traveled in 15 seconds by an object traveling at a constant velocity of 20 feet per second

Answers

The distance travel by the object would be 300 feet

The distance covered by the object is 300 feet's.

We have - object traveling at a constant velocity of 20 feet per second.

We have to calculate the distance traveled in 15 seconds by the object.

What is the formula to calculate the distance covered by the object ?

The distance covered by the object can be calculated using the formula -

d = v x t

Where -

v - it is the velocity of object

t - time taken by object

According to question -

v = 20 feet/sec

t = 15 seconds

Hence, the distance covered will be -

d = 20 x 15 = 300 feet's

Hence, the distance covered by the object is 300 feet's.

Cant really show you how to do it but the graph would start at the y axis at (0,-2) then from there each point would move to the left 4 and up 7 or back 4 and down 7. It would form a straight line.

can somebody simply explain a unlinear functions???

Answers

Answer:

The graph of a linear function is a line. ... Linear functions have a constant slope, so nonlinear functions have a slope that varies between points. Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions.

nonlinear functions are functions that are not linear functions. Therefore, they have the opposite properties of a linear function. The graph of a linear function is a line. Thus, the graph of a nonlinear function is not a line.

True or false: When you multiply or divide an inequality by a negative, you flip the inequality sign
Plz tell me

Answers

Answer:

[tex]\boxed {\tt True}[/tex]

Step-by-step explanation:

This is true. Whenever you divide or multiply an inequality by a negative number, you must flip the inequality sign.

Here is an example:

[tex]-9x>27[/tex]

We have to divide both sides of the inequality by -9. Since it is a negative number, flip the inequality sign.

[tex]\frac{-9x}{-9} <\frac{27}{-9}[/tex]

[tex]x<\frac{27}{-9}[/tex]

[tex]x<-3[/tex]

So, it is true that you must flip the inequality sign when multiplying or dividing by a negative number.
