Answer:
(x) = 
Step-by-step explanation:
let d(x) = y and rearrange making x the subject, that is
2x - 4 = y ( add 4 to both sides )
2x = y + 4 ( divide both sides by 2 )
x = 
Change y back into terms of x, so
(x ) =
Answer:
y= -1/4x + (-1)
Step-by-step explanation:
(4,-2) (0,-1)
m= y2-y1/x2-x1
m=-2-(-1)/4-0
m= -1/4
y= mx + b
-2= -1/4(4)+ b
-2= -1 +b
+1 +1
-1= b
Answer:
x = 49
Step-by-step explanation:
Let's solve for x in the first triangle by applying the leg rule.
Leg rule is given as: hypotenuse/leg = leg/part
Hypotenuse = x
Leg = 28
Part = 16
Plug in the values into the equation
x/28 = 28/16
Cross multiply
x*16 = 28*28
16x = 784
x = 784/16
x = 49
✔️Let's check our answer to see if we would get the same value of x for the other triangle. Apply the same leg rule.
Hypotenuse = x
Leg = 21
Part = 9
Thus:
x/21 = 21/9
Cross multiply
x*9 = 21*21
9x = 441
x = 441/9
x = 49
✔️We have the same value. Therefore, x = 49 is the correct answer.
Answer:
where r yr series
Step-by-step explanation:
For example, the sequence 3, 5, 7, 9 ... is arithmetic because the difference between consecutive terms is always two. The sequence 21, 16, 11, 6 ... is arithmetic as well because the difference between consecutive terms is always minus five.
