(a) y = 2x + 3
(b) (1,5), (3,3); y = 3x + 3 5 = m1 + b, 3 = m3 + b
(c) coincident i believe, because it is not independent or inconsistent
(d) 2x + 3 = 3x + 3
(-2x)(-3) (-2x)(- 3)
0 = -2x
x = 0
hope this helps
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
The general form of cosine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : 0
In function, 
Amplitude : 
y-intercept : -1
Therefore, the correct options are B and D.
To find the average of the data
Answer:
x = -119/3 = -39 2/3
Step-by-step explanation:
(128 +7x- 12) = (4x - 3)
Combine like terms
(116 +7x) = (4x - 3)
Subtract 4x from each side
116 +7x-4x=4x-4x-3
116 +3x = -3
Subtract 116 from each side
116-116 +3x = -3-116
3x = -119
Divide each side by 3
3x/3 = -119/3
x = -119/3
x = -39 2/3
Answer: 76.2
Step-by-step explanation:
Perimetar of isiscales triangle is calculated using equation;
P=b+2a
b=9
P=49
lets find sides of triangle.
P-b=2a
a=(P-b)/2
a=49-9/2
a=40/2=20
If another triangle is similar that means that his base and sides are proportional to first triangle.
Base of first trianlge b₁=9
Base of similar triangle is b₂=14
use proportion to find out side of similar triangle:
b₁:b₂=9:14
a₁:a₂=9:14
a₁=20
20: a₂=9:14
a₂=14*20/9=280/9=31.1
Perimetar of second triangle is:
P₂=b₂+2a₂
P₂=14+2*31.1=14+62.2=76.2
