X + Y = 4
2x - 3Y = 6
Substitution or Elimination?
Answer:
(x, y) = (18/5, 2/5)Step-by-step explanation:
x + y = 4
x = 4 - y
2x - 3y = 6
Substitution x2x - 3y = 6
2(4 - y) - 3y = 6
8 - 2y - 3y = 6
-5y = 6 - 8
-5y = -2
y = 2/5
Substitution yx = 4 - y
x = 4 - 2/5
x = 20/5 - 2/5
x = 18/5
(x, y) = (18/5, 2/5)Find the axis of symmetry and the vertex of the graph of f(x) = 4x^2-8x+3.
Answer:
(1, -1) and x= -1
Step-by-step explanation:
The vertex is (1, -1)
The parabola params are:
a=4, b=-8, c=3
v= −b/2a
- (−8)/ 2 · 4
Simplify
v=1 v=1
Plug in v=1 to find the y value
y=−1
Therefore the parabola vertex is
(1, −1)
The axis of symmetry is the line that passes through the vertex and focus.
Therefore, your axis of symmetry is
x= -1

Back : 40
Right side : 15
Left side : 15
Top : 24
Bottom : 24
Total : 158ft squared
Hope this helps!
The surface area of the rectangular prism 158 square feet.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.
The rectangular prism will have six faces. The surface area will be calculated as:-
Surface area = 2 ( 3x5) + 2 ( 8x3) + 2(8x5)
Surface area = 30 + 48 + 80 = 158 square meters
Therefore the surface area of the rectangular prism is 158 square feet.

11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89

A ladder is leaning on a wall. The ladder is 45 feet long. The angle formed by the ladder and the ground is 32. How far does the ladder reach up the wall?
Answer:
23.85 feets
Step-by-step explanation:
Given that :
Length of ladder, L = 45 feets
Angle formed by ladder and ground, θ = 32°
Using trigonometry :
Sin θ = opposite / hypotenus
Opposite = h
Hypotenus = 45
Sin 32 = h / 45
0.5299192 * 45 = h
23.846366 = h
Hence, height of ladder = 23.85 feets

Fiona races BMX around a circular dirt course. If the radius of the course is 60 meters, what is the total distance Fiona covers in two laps of the race?
Answer:
753.6 meters
Step-by-step explanation:
Given :
Fiona races a BMX in a dirt course.
The course in circular in shape. The radius of the dirt course is 60 meters.
So the circumference of the dirt course is given by :
[tex]$C = 2 \pi r$[/tex]
= 2 x 3.14 x 60
= 376.8 meters
So the total outer distance of the circular dirt course is 376.8 meters.
Therefore, the total distance that Fiona covers in the two laps of the race is
= 376.8 + 376.8
= 753.6 meters

Answer:
m = - 3, c = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2y + 6x = - 4 ( subtract 6x from both sides )
2y = - 6x - 4 ( divide terms by 2 )
y = - 3x - 2 ← in slope- intercept form
with slope m = - 3 and y- intercept c = - 2

Answer:
9p = 81 degrees
Step-by-step explanation:
All the angles in a triangle equal 180 degrees in total.
So the equation would be:
9p + 7p + 4p = 180
20p = 180
p = 9
So just plug it in:
