what is the y-intercept for 3x^2 + 2x - 1

Answers

Answer 1

Answer:

y- intercept = - 1

Step-by-step explanation:

To find the y- intercept , let x = 0 in the equation and evaluate for y

y = 3(0)² + 2(0) - 1 = 0 + 0 - 1 = - 1

y- intercept = - 1 or (0, - 1) in coordinate form

Answer 2

Answer:

Plug x=0 into the equation and solve the resulting equation

The y-intercept:

3x^2 + 2x - 1

3(0)^2 + 2x(0)- 1

0+0-1

-1

y=−1 is intercept for y  

(0,−1)

Answer:

x=7+1/2

Step-by-step explanation:

 We move all terms to the left:

3(x+4.5)-(36.)=0

We add all the numbers together, and all the variables

3(x+4.5)-36=0

We multiply parentheses

3x+13.5-36=0

We add all the numbers together, and all the variables

3x-22.5=0

We move all terms containing x to the left, all other terms to the right

3x=22.5

x=22.5/3

The art department at a school sold 323 tickets
to an art show, for a total of $790. Students paid
$2 for tickets, and non-students paid $3.50. The
principal asked how many non-students
attended the art show.

Answers

Answer:

96 students

Step-by-step explanation:

x + y = 323

2x + 3.5y = 790

=> by elimination

2x+3.5y=790

2x+ 2y = 646

__________-

1.5y = 144

y = 144/1.5 = 96

The system of equations are

x + y = 323

2x + 3.5y = 790

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the system of equations be A and B

Now , the number of tickets sold = 323 tickets

Let the number of students be = x

Let the number of non students = y

So , x + y = 323   be equation (1)

The cost for students = $ 2

The cost for non students = $ 3.50

The total cost of all the tickets = $ 790

So , 2x + 3.5y = 790   be equation (2)

On simplifying the equations , we get

Multiply equation (1) by 2 , we get

2x + 2y = 646   be equation (3)

Subtracting equation (3) from equation (4) , we get

1.5y = 144

Divide by 1.5 on both sides of the equation , we get

y = 96

So , the number of non students be y = 96

Substituting the values of y in equation (1) , we get

x = 323 - 96 = 227 students

Now , the graph of the equations is plotted and the point of intersection is the solution ( 227 , 96 )

Hence , the equations are solved

Answers

Answer:

22 days

Step-by-step explanation:

Given data

Number of students= 50

Number of days= 32days

We want to find the number of students that can have food for 14days

If 50 students will have food for 32 days

x students will have food for 14 days

Step-by-step explanation:

Answer:

Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Answers

Answer:

150 degrees

Step-by-step explanation:

I think V and T add up to 180 degrees (and all angles in a whole quadrilateral add up to 360) so if you add them and make it equal 180 you can solve x.

So x + 3x + 60 = 180

4x = 120

x = 30 degrees

So V is 3(30) + 60 = 150 degrees

Answer:

7. x = 38°

8. y = 65°

9. 261° and 81°

Step-by-step explanation:

Finding x:

You can make an equality with (2x +5) and (3x +33) because the value of these angles are the same, so:

2x +5 = 3x -33

2x - 3x = -33 -5

-x = -38

x = 38°

Finding y:

You can find the value of y making another equally, but this time you have to sum (4y -1) with (3x - 33) or (2x +5) and equal it with 180°:

(4y -1)+(2x +5) = 180

4y -1 +2x +5 = 180

4y +2x +4 = 180

We know from the question 7 that x is 38°:

4y +2•(38) +4 = 180

4y - 76 +4 = 180

4y - 80 = 180

4y = 180 + 80

4y = 260

y = 260/4

y = 65

Finding the value of the angles:

You just have to put the value of x and y in their places and make the calculations:

4•65 +1 = 261°

3•(38) -33 = 81°
