Answer:
t = ±12
Step-by-step explanation:
t^2=144
Take the square root of each side
sqrt(t^2)=± sqrt(144)
t = ±12
x - 3y = 1 ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
-14y = -8
-14 -14
y = ⁴/₇
x - 3y = 1
⁴/₇ - 3y = 1
- ⁴/₇ - ⁴/₇
-3y = ³/₇
-3 -3
y = ⁻¹/₇
(x, y) = (⁴/₇, ⁻¹/₇)
It would be a reflection across the x acess
Answer:
1947 units^2
Step-by-step explanation:
you can split it up into different sections of rectangles.
the first one is 25x39= 975
The second section is the connector which you do
43-25=18
and you do 39-27=12 and then
you multiple 18x12 which equals 216
and the final section you do 24+12=36
and 36x21=756
and finally you add them all up to equal 1947 units^2
Answer:
The number of cases prior to the increase is 50.
Step-by-step explanation:
It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.
We need to find the number of cases prior to the increase.
Let x be the number of cases prior to the increase.
x + 13.6% of x = 57
Divide both the sides by 1.136.
Therefore the number of cases prior to the increase is 50.
