-2x+y=1 solve with steps

Answers

Answer 1

Answer:

x=1 and y=3

Step-by-step explanation:

-2x1=-2

-2+3=1

So this answer makes sense

Answer 2

Answer:

y = 2x + 1

Step-by-step explanation:

Given: -2x+y=1

Add 2x to both sides: y=1+2x

Reorder: y = 2x + 1

I am not sure exactly what you need for this point, but here is the equation in y=mx+b form aka slope-intercept form

m = slope = 2

b = y-intercept = 1

Hope this helps, have a nice day :D

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?

Answers

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

A wheel rotates 15 times each minutes. How many degrees will it rotate in 1 second of time?​

Answers

Answer:

In 1 second it Rotates 15× 360 / 60

Step-by-step explanation:

Wheel Rotates 15 times in 60 seconds

This implies that the wheel completes

15 × 360 degrees in 60 seconds

therefore,

In 1 second it Rotates 15× 360 / 60

=> 15×6 = 90 °

in 12 seconds , 12×90 = 1080°.

Two rules for creating a pattern are given below.

Rule 1: Multiply x by 5 to get y.

Rule 2: Add 12 to x to get y.

Which ordered pair, (x,y), works for both rules?

Choose 1 answer:

(Choice A)

(5,25)

(Choice B)

(3,15)

(Choice C)

(0,12)

Answers

Choice B

First make an equation for both rules.
Rule 1: y=5x
Rule 2: y= x+12

Then plug in each ordered pot to find which one works

Choice A (5,25)
Rule 1: 25=5(5)
25=25
Rule 2: 25=5+12
25=17
Choice a works for rule 1 but not rule 2 therefore it does not work

Choice b (3,15)
Rule1: 15=3(5)
15=15
Rule 2: 15=12+3
15=15
Choice be works works for both equations therefore it is the answer

Choice c (0,12)
Rule 1: 12=5(0)
12=0
Rule 2: 12=12+0
12=12
Choice c works for rule 2 but not 1 do it cannot be the answer.

Find intercepts of: 3x-3y+9=0
X-intercept as a ordered pair
Y-intercept as a ordered pairr

Answers

3x - 3y + 9 = 0

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). It is also the value of y when x = 0.

To solve for the y-intercept, set x = 0:

3(0) - 3y + 9 = 0
3(0) - 3y + 9 = 0

Subtract 9 from both sides:
- 3y + 9 - 9 = 0 - 9
- 3y = -9
Divide both sides by -3 to solve for y:

-3y/-3 = -9/-3
y = 3

Therefore, the y-intercept is (0, 3).

The x-intercept is the point on the graph where it crosses the x-axis, and has coordinates of (a, 0). It is also the value of x when y = 0.

To solve for the x-intercept, set y = 0:

3x - 3(0)+ 9 = 0
3x -0 + 9 = 0

Subtract 9 from both sides:
3x + 9 - 9 = 0 - 9
3x = -9

Divide both sides by 3 to solve for x:

3x/3 = -9/3
x = -3

Therefore, the x-intercept is (-3,0).

The correct answers are:
Y-intercept = (0, 3)
X-intercept = (-3, 0)

A machine can blow up 20 balloons in 4 min.
How many balloons can it blow up in 60 min?

Answers

Answer:

120

Step-by-step explanation:

all you have to do is multiply 20*60

Answer:

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.

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.

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.

Hey can anyone help with this question please and thank you

Answers

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).

Find: 11/3 divided by 2/3
The quotient is 5 and ______

Answers

Answer:

1/2

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.

What is a Vector?

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.
