Answer:
B. b = 3a + 2
Step-by-step explanation:
We can write the equation in slope-intercept form as b = ma + c, where,
m = slope/rate of change
c = y-intercept/initial value
✔️Find m using any two given pair of values, say (2, 8) and (4, 14):
Rate of change (m) = change in b/change in a
m = (14 - 8)/(4 - 2)
m = 6/2
m = 3
✔️Find c by substituting (a, b) = (2, 8) and m = 3 into b = ma + c. Thus:
8 = 3(2) + c
8 = 6 + c
8 - 6 = c
2 = c
c = 2
✔️Write the equation by substituting m = 3 and c = 2 into b = ma + c. Thus:
b = 3a + 2
Answer:1/3
Step-by-step explanation:
5/15
Answer:
C
Step-by-step explanation:
The options are:
<em>A. 4 + (-4) = 0
</em>
<em>B. -8 + (-3) = -3 + (-8)
</em>
<em>C. 2 </em>×<em> 1/2 = 1
</em>
<em>D. 8/5 + 0 = 8/5</em>

The inverse property of multiplication states that the product of a number and its inverse is one.
The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1
, as the property states.
Answer:
The slope is 3/2
Step-by-step explanation:
(3,0) & (1,-3)
m=y²-y¹/x²-x¹
m=(-3)-0/1-3
m=-3/-2
m=3/2
Answer:
<h3>23.5"</h3>
Step-by-step explanation:
Please see attached a sketch of the television
the size of a television is described by the length of its diagonal in inches.
in this case, the diagonal of the television is 48"
we are told that the aspect ratio is 16:9
hence the dimension of the television as seen from the draft is
length= 16x
height=9x
Applying Pythagoras theorem
(16x)^2+(9x)^2= 48^2
256x^2+81x^2=2304
337x^2=2304
divide both sides by 337 we have
x^2=2304/337
x^2=6.8367
x=√6.8367
x=2.6
What is the height
H=9x
=9(2.6)
=23.5"
