Put this into slope form x/2 + 2y= 6

Inga [223]

Answer:

y=-1/4x +3

Step-by-step explanation:

x/2 + 2y = 6

Subtract x/2 from both sides

2y=-x/2 +6

Simplify by dividing by 2

4−(3x−8)=21 solve this pls

riadik2000 [5.3K]

Answer:

4 - ( 3x - 8 ) = 21

break the bracket first ,it gives : 4 - 3x + 8 = 21

12 - 3x = 21

- 3x = 21 - 12

- 3x = 9

-x = 9/3

-x = 3

X = - 3

[ check if the answer is correct, put -3 instead of X in the above equation ! we get 4 - { 3(-3) - 8 } = 21

4 - { - 9 - 8 } = 21

4 - { - 17 } = 21

break the bracket, minus and minus will multiply and will become plus , so we have 4 + 17 = 21 , hence 21 = 21 ! therefore X = -3

Determine the measure of ∠Y. images attached

Gwar [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y

To find the value of ∠Y we use tan

We have

$\tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...$

We have the final answer as

Hope this helps you
