Answer:
y = 2x + 3
Step-by-step explanation:
y = ?x + 3
(0,2)
+4 +2
(4,5)
mx = 4/2 = 2
y = 2x + 3
hope this helps :)
Answer:
The Width = 65.44 inches
The Height = 36.81 inches
Step-by-step explanation:
We are told in the question that:
The width and height of an newer 75-inch television whose screen has an aspect ratio of 16:9
Using Pythagoras Theorem we known that:
Width² + Height² = Diagonal²
Since we known that the size of a television is the length of the diagonal of its screen in inches.
Hence, for this new TV
Width² + Height² = 75²
We are given ratio: 16:9 as aspect ratio
Width = 16x
Height = 9x
(16x)² +(9x)² = 75²
= 256x² + 81x² = 75²
337x² = 5625
x² = 5625/337
x² = 16.691394659
x = √16.691394659
x = 4.0855103303
Approximately x = 4.09
For the newer 75 inch tv set
The Height = 9x
= 9 × 4.09
= 36.81 inches
The Width = 16x
= 16 × 4.09
= 65.44 inches.
A = LW
W = L + 6
A = 160
160 = L(L + 6)
160 = L^2 + 6L
L^2 + 6L - 160 = 0
(L + 16)(L - 10) = 0
L + 16 = 0
L = -16 (extraneous solution...not ur answer)
L - 10 = 0
L = 10 <====the length (L) = 10 yds
W = L + 6
W = 10 + 6
W = 16 < ==== width (W) = 16 yds
The answer is 1 inch equals 8
Answer:
y = 4x - 1
Step-by-step explanation:
slope: 7-3/2-1 = 4
y= mx+b
7= 4(2) + b
b= -1
y = 4x - 1
