Answer:
y-intercept: 
axis of symmetry: 
vertex: 
Step-by-step explanation:
To find the y-intercept, set x = 0 and solve for y.
I am assuming f(x) = y
The y-intercept of the equation is y = 0.
Now, for the axis of symmetry, you need the equation 
In an equation.. 
In this case, there is only an a, so plug in the values into the equation.
The axis of symmetry is x = 0.
To find the vertex, change the format of the equation from standard form to vertex form.
Vertex form: 
The vertex is 
The vertex in this case is (0,0).
Graphing makes things a lot easier. If you can graph it, all you have to do is look at the graph and the answers are all there!
Hope this helped you!
The volume of the box is
.. V = (90 cm)*(45 cm)*(45 cm) = 182,250 cm³
The empty 15% of the volume is then
.. empty volume = 0.15*182,250 cm³ = 27,337.5 cm³
This will require
.. (empty volume)/(volume / bag) = 27,337.5 cm³ / (28,316 cm³/bag) ≈ 0.97 bag
to fill.
Selection A. 1 bag is appropriate.
Substitute y = 1/5 x + 1 into x + 5y = -15
x + 5y = -15
x + 5(1/5 x + 1) = -15
x + x + 5 = -15
2x = -20
x = -10
Plug in x = -10 into y = 1/5 x + 1
y = 1/5 (-10) + 1
y = -2 + 1
y = -1
(-10 , -1)
Answer is the last one
(-10 , -1)
Answer:
x(3x-6)=0
Step-by-step explanation:
x(3x-6)=0
Two solutions were found :
x = 2
x = 0
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
3x - 6 = 3 • (x - 2)
Equation at the end of step 2 :
3x • (x - 2) = 0
Step 3 :
Theory - Roots of a product :
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
3.2 Solve : 3x = 0
Divide both sides of the equation by 3:
x = 0
Solving a Single Variable Equation :
3.3 Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
Two solutions were found :
x = 2
x = 0
Answer:B is similar
Step-by-step explanation:
Do you know triangles add up to 180°
So...
180-(90+58)= 32°
