Answer:
f(x+2) = - 6x - 5
Step-by-step explanation:
As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
To 1/2 of 3/4 you multiply the two fractions together (multiply straight across, numerator*numerator and denominator*denominator) which gets you to your answer which is 3/8

Answer:
4. height: 5√3 cm; area: 25√3 cm²
5. 30√2 ft ≈ 42.43 ft
Step-by-step explanation:
4. The height of an equilateral triangle is (√3)/2 times the side length, so is ...
height = (√3)/2 × (10 cm) = 5√3 cm
The area is given by the formula ...
A = 1/2bh
A = 1/2(10 cm)(5√3 cm) = 25√3 cm²

5. The diagonal of a square is √2 times the side length, so the distance from 3rd to 1st base is ...
(30 ft)√2 ≈ 42.43 ft
__
The length of the diagonal of a square is something you should be familiar with. If you're not, you can figure the distance using the Pythagorean theorem.
d = √(30² +30²) = √1800 ≈ 42.43 . . . feet

Answer:
x = 5
Step-by-step explanation:
The arc subtended by the marked angle is ...
360° -226° = 134°
The measure of the marked angle is half this, so we have ...
15x -8 = 134/2
15x = 75 . . . . . . . add 8
x = 5 . . . . . . divide by 15
