Answer:
Step-by-step explanation:
I think the first part of that is asking for the equation for the line of symmetry, although I do not have access to your drop down menu to know for sure! The axis of symmetry is the equation that splits the parabola into 2 parts that are mirror images of each other. In this type of parabola, it will be an "x = " equation. The line that splits the parabola in half is the line x = -2. The function is increasing where the y values are going up. This happens in the interval (-∞, -2].
The function is decreasing where the y values are going down. This happens in the interval [-2, ∞)

Answer:
-10 or (0, -10) as an ordered pair
Step-by-step explanation:
The y-intercept is the value of y when x=0. Using x=0 in the equation gives ...
y -2 = 3(0 -4)
y = -12 +2
y = -10 . . . . . the y-intercept
<span>7x - 2 = 2y
7x = 2y + 2
so
</span>7x = 2y + 2<span>
3x = 2y - 1
----------------subtract
4x = 3
x = 3/4
</span>7x - 2 = 2y
7(3/4) - 2 = 2y
21/4 - 2 = 2y
21/4 - 8/4 = 2y
13/4 = 2y
so
y = 13/4 * 1/2
y = 13/8
answer
<span>(3/4, 13/8)</span>
Answer:
147 degrees
Step-by-step explanation:
all the angles of a triangle add up to 180 degrees. so, you must perform the operation 180-(83+64) which equals 33. this is the angle supplementary to angle 1. to find angle 1, you must subtract 180 and 33 since supplementary angles add up to 180 degrees. this is equal to 147 degrees.
Answer:
$2315.25
Step-by-step explanation:
Given data
Principal= £2000
Time= 3 years
Rate= 5%
The compound interest expression is
A= P(1+r)^t
substitute
A= 2000(1+0.05)^3
A= 2000(1.05)^3
A= 2000*1.157625
A= 2315.25
Hence the Amount is $2315.25
