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:
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:
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
how is energy involved in the process of mountains shaping the earths surface?
Answer:
movement in the tectonic plates in the crust, wind and water erosion, and deposition shapes the earth's surface
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.

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°

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.
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

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
cross multiply
32*x= 14*50
32x= 700
x= 700/32

What is the slope?
m= 1/2
m=2/1
m= -1/2
m= -2/1
Answer:
m = 2/1
Step-by-step explanation:
Slope is rise over run
Looking at the graph we know the slope is positive since it goes up from left to right
We have a point at (2,0)
We have another point at (3,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(3-2)
= 2/1
