-2x+y=1 solve with steps

Answer: f(x) is an odd function

Step-by-step explanation: The major characteristic of odd functions is that one end of the graph goes down to negative infinity, the other end goes up to positive infinity.

Answer:

-4[tex]\leq[/tex]x<3

Step-by-step explanation:

1)Break this into 2 case, equal to 0 and and less than 0.

2)The number equals zero if its numerator is 0 which happens when x=-4.

3) A fraction is less than 0 it is negative. Negative fractions are either +/- or -/+,  so we have two subcases.

3a) For +/- the numerator is positive when x>-4 and denominator is negative when x<3. Putting those two together we have -4<x<3.

3b)For -/+ the numerator is negative when x<-4 and the denominator is positive when x>3 however those two values don't overlap.

4) Putting this together we have -4[tex]\leq[/tex]x<3

Step-by-step explanation:

11/3 divided by 2/3

=5.5

11/3 divided by 2/3 , the quotient is 5 and remainder is 1.

The divisor is the integer that divides a given number. The resultant number is sometimes referred to as the quotient. The residual is the number that the divisor leaves after partially dividing the original integer.

Let,  first number is x and second number is y

On dividing given two number

Division=x/y

[tex]x/y=\frac{11/3}{2/3}[/tex]

[tex]x/y=11/2[/tex]

It is given that the quotient for dividing two numbers is 5.

Using,

Dividend = Divisor x Quotient + Remainder

Here,

Dividend =11

Divisor =2

Quotient =5

On, substituting these values to get Remainder

11=2 x 5+ Remainder

Remainder=1

Thus, remainder is 1.

Answer:

0.75

Step-by-step explanation:

I hope this helps!

We must do rise over run to find the slope.

First find 2 points that cross the corner of the grid as shown in the attached image.

Then count how many units up and over it takes to connect the 2 points. For this example, there are 3 up and 4 across.

ΔX = 0 – -4 = 4

ΔY = 1 – -2 = 3

Slope (m) = ΔY/ΔX = 3/4 = 0.75

To solve for slope, it would be [tex]\frac{rise}{run}=\frac{3}{4} =0.75[/tex] is the slope.

Answer:

Step-by-step explanation:

because 4 times 8 is 32 and .5 times 8 is 4 so 32 plus 4 is 36

Answer:

(7x-4)°= (3x+28)°. ( :. m || n, so it is alternate angle)

7x° - 4° = 3x° + 28°

4x° = 32°

x = 32/8

x = 4°

Answer:

x = 8

Step-by-step explanation:

< (7x - 4)° and < (3x + 28)° are Alternate interior angles that do not have a common vertex on alternate sides of the transversal, t. Therefore, they have the same measure.

We can establish the following equality statement to solve for x :

< (7x - 4)° = < (3x + 28)°

Subtract 3x from both sides:

7x -3x - 4 = 3x - 3x + 28

4x - 4 = 28

Add 4 to both sides:

4x - 4 + 4 = 28 + 4

4x = 32

Divide both sides by 4 to solve for x:

4x/4 = 32/4

x = 8.

To verify whether the value of x is correct, substitute x = 8 into the equality statement:

< (7x - 4)° = < (3x + 28)°

< [(7(8) - 4]° = < [3(8) + 28]°

< (56 - 4)°  = < (24 + 28)°

< 52° = < 52° (True statement. Therefore, the correct answer is x = 8).

Answer

Step-by-step explanation:

Answer:

the magnitude of the vector is given by the √(px^2+py^2) so the value is 5.65

The magnitude of the given vector (4, -4) in the simplified form will be 5.65.

A vector is a quantity with both magnitude and direction in physics. It is often depicted by an arrow with the same direction as the amount and a length proportionate to the size of the quantity.

A vector lacks position, but has magnitude and direction. A vector is therefore unaffected by displacement parallel to itself as far as its length is unaltered.

As per the given data in the question,

4² + (-4)² = 16 + 16

= 32

Magnitude = √32

Magnitude = 5.65

Answer: 76 hamburgers

Step-by-step explanation:

first we will write an equation:

x+3x=304

which simplified turns in 4x=304

x=76

now go back to our equation and solve.

3x is cheese burgers= 228 cheeseburgers

x is hamburgers =76 hamburgers

Answer:

The numbers are 24, 16 and 48

Step-by-step explanation:

For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.

88=x+(x+8)+3x

Now you simplify the equation,

88=5x+8

Now get the x and it’s coefficient alone on one side

80=5x

Now divide both sides so the x is alone

x=16

Since the second number was x you know the second number

the first number is x+8 since x is 16 the first number is 24

The third number is 3 * x so the third number is 48.

So the numbers are 24, 16 and 48

The machine can blow up 300 balloons in 60 min.

Step-by-step explanation:

60 ÷ 4 = 15. 15 x 20 = 300. We know it takes 4 minutes to blow up 20 balloons. 4 minutes is only 1/15 of 60, so that means you have to blow up 20 balloons 15 times, which will take 60 minutes, and in that 60 minutes, you blew up 300 balloons.
