Answer:

b. (1.4y)

Step-by-step explanation:

When a variable has no number next to it, it is always going to be 1 multiplied by the variable. adding 1y and 0.4y would make 1.4y.

P(5,3); y=4x<br><br>if you help me I will be thankful forever pls
horrorfan [7]
Y= -1/4x + 4.25, perdendicular then it must be the opposite of 4x which is -1/4. Then you multiply it with 5 and then add or subtract a number so you can find 3. So -1/4× 5 + 4.25= 3. Here you gooo!

-2/3y-3/4=5 <br> What is the answer i need to show my work please
vodka [1.7K]

Answer:

y=  -69/8  (negative 69 over 8)

Step-by-step explanation:

First, you have to simplify both sides of the equation:

-2/3y+ -3/4 =5

Second, add 3/4 to both sides:

-2/3y +-3/4 + 3/4=5 +3/4

-2/3y= 23/4

Next, multiply both sides by 3/(-2) (3 over -2)

(3/-2)*(-2/3y)= (3/-2) * (23/4)

<em><u></u></em>

<em><u>y= -69/8</u></em>
