The correct answer for the exercise shown above is the first option and the las option, which are:
<span>y = 3x + 20
3x - y = -20
</span>
The explanation is shown below:
1. You have the folllowing expression given in the problem above:
y-2=3(x+6)
2. If you solve it for y, you have:
y-2=3x+18
y=3x+18+2
y=3x+20
3. And if you move the variables to the left member, you have:
3x-y=-20
Therefore, as you can see, the correct answer are the options mentioned above.
Answer:
16.5km
Step-by-step explanation:
Liola drives 17km up a hill that is at a grade of 14 degrees. What horizontal distance, to the nearest tenth of kilometer, has she covered?
We solve using Trigonometric function of Cosine
cos theta = Adjacent/Hypotenuse
Theta = 14°
Hypotenuse = Distance up the hill = 17km
Adjacent = Horizontal distance = x
Hence,
cos 14 = x/17
Cross Multiply
x = cos 14 × 17
x = 16.495027347km
Approximately = 16.5km
The horizontal distance = 16.5km
Answer:
n= 16
Step-by-step explanation:
Answer:
a) 90
b) 256
Step-by-step explanation:
1² + 2³ + 3⁴
= 1 + 2³ + 3⁴
= 1 + 8 + 3⁴
= 9 + 34
= 9 + 81
= 90
4² × 2⁴
= 16(2⁴)
= (16)(16)
= 256
