Answer:
Below
Step-by-step explanation:
● |y+2| > 6
● y+2 > 6 or y+2 < -6
Add -2 in both sides in the two inequality.
● y+2-2 > 6-2 or y+2-2 < -6-2
● y > 4 or y< -8
Answer:
180 cm^2
Step-by-step explanation:
For similar figures the ratio of areas is the square of the ratio of linear dimensions.
We take "tripled in size" to mean that the linear dimensions of the larger rectangle are 3 times those of the smaller rectangle. That means the area of the larger rectangle will be 3² = 9 times the area of the smaller one.
Area = (3²)(20 cm²) = 180 cm² . . . . area after tripled in size
Answer:
I believe that is correct. But there are other ways to define a linear equations along with this one :)
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6

Answer:
1) 5/12
2) 4/3
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the tangent ratio is ...
Tan = Opposite/Adjacent
__
1) For angle Z, the ratio is ...
tan(Z) = XY/YZ = 10/25 = 5/12
__
2) For angle C, the ratio is ...
tan(C) = AB/BC = 20/15 = 4/3
