C.6y=4x-30


D.(y+3)=2/3(x-3)

Answers

Answer 1
Answer: A is wrong because the Y-Intercept: = −13/3

B is correct because y=2/3x-5

c is correct because 6y=4x-30

and lastly D is correct because .(y+3)=2/3(x-3)
Answer 2
Answer: Answer choice A is incorrect as it is missing the variable 'x' in it.

Let's test answer choice B.

y = mx + b

m is the slope
b is the y-intercept

m = 2/3
b = -5

y = (2/3)x - 5

B is one of the answers.

Let's test answer choice C.

6y = 4x -30

y = (4/6)x - 30/6
y = (2/3)x - 5

Answer choice C is also correct.

Let's test answer choice D now.

y = (2/3)x - 5
Plug in (3,-3)
-3 = (2/3)(3) - 5
-3 = 2 - 5
-3 = -3
This is correct, so therefore D is also one of the answers.

Your answer is B, C and D.

Answers

Answer:

x = (5)/(26)

Step-by-step explanation:

Given equation:

(3)/(4)x + (5)/(8) = 4x

(3(2)x + 5)/(8) = 4x            ∵taking GCF 8

(8 (6x + 5) )/(8)  = 4x × 8

6x + 5 = 32x    ⇒   5 = 32x - 6x   ⇒  5 = 26x   ⇒  x = (5)/(26)

9.64 rounded to the nearest tenth

Answers

Hello,

9.64 rounded to the nearest tenth is 9.6.

Have A Good Day.
Your answer would be 9.6

.6 is a six tenths.

To help you remember to round up or down remember this rhyme: 5 or more raise the score. 4 or less give it a rest.

9.64 is rounded to the nearest hundredth. To get to the nearest tenth you need to get rid of the four. Since it's less than 5, you just knock it away like it wasn't ever there. If it's 5 or above, you would have to round the number up. If you had to round up it'd be 9.7.
