Elimination: 

3x - 9y = 3
6x - 3y = -24

3x - 9y = 3
18x - 9y = -72
(subtract)
-15x = 75
÷ -15
x = -5

(3 × -5) - 9y = 3
-15 - 9y = 3
+ 15
-9y = 18
÷ -9
y = -2

Substitution:

6x - 3y = -24
+ 3y
6x = -24 + 3y

÷ 6
x = 4 + 0.5y

3(4 + 0.5y) - 9y = 3
12 + 1.5y - 9y = 3
12 - 7.5y = 3
- 12
-7.5y = -9
÷ -7.5
y = 1.2

x = 4 + (0.5 × 1.2)
x = 4 + 0.6
x = 4.6

So this one didn't fail as much, but I got different numbers. If you have to give in values, I'd give in the values from the elimination because I don't trust myself when it comes to the substitution

If cos Φ8/17 find the other five trigonometric ratios​
NeX [460]

Answer:

cos theta=8/17

8/17=A/H

finding O,

O ² + A² =H ²

(8)²+O²=(17)²

64+O²=289

O²=289-64

O²=225

O=√225

O=15

we know that H=17, A=8, O=15

therefore, the other trigonometric ratios are

sinФ=O/H=15/17

tanФ=O/A=15/8

cosecФ=H/O=17/15

secФ=H/A=17/8

cotФ=A/O=8/15

hope it helps u!

If a=5+2i, b=-3+i and c=4i(2+3I), determine ab+c in simplest a+bi form
Nady [450]

Answer:

-29+7i

Step-by-step explanation:

(5+2i)(-3+i)

-15+5i-6i+2i²

i²=-1

Simplify

-17-i

Add c

c=4i(2+3i)

=8i+12i²

=8i-12

-17-i+8i-12

-29+7i
