Cy+4=d−9y solve for y
tiny-mole [99]

Answer:

Answer:

y= d−4 /c+9

Step-by-step explanation:

cy+4=d−9y

Step 1: Add 9y to both sides.

cy+4+9y=d−9y+9y

cy+9y+4=d

Step 2: Add -4 to both sides.

cy+9y+4+−4=d+−4

cy+9y=d−4

Step 3: Factor out variable y.

y(c+9)=d−4

Step 4: Divide both sides by c+9.

y(c+9)  c+9 = d−4 /c+9

y= d−4 /c+9

Consider two unique parallel lines. What aspects of these two lines are the same? What aspects of these two lines would have to
scoray [572]
Parallel lines must have the same slope.  However for them to be UNIQUE lines, ie different lines, they must have a different y-intercept.

So if we say generally that a line is y=mx+b where m is the slope and b is the y-intercept then these two unique parallel lines would be:

y1=mx+h and y2=mx+k

Where m is the same for both and each have unique constants h and k where they cross the y-axis

Hi! please help! thank you
Leno4ka [110]

Answer:

1) p≥2

2) e-9=13

3) f<5

Step-by-step explanation:

1) If there are at least two slices left, there could be more, so use p≥2, meaning p is greater than or equal to 2.

2) e is your starting amount, so put that first, then it says it decreases by 9, so it is e-9=13.

3) If there are fewer than 5, it can not be 5 so you use <.

f<5 or gallons is less than 5.

25 x (5 - 2) ➗ 5 - 12
joja [24]

Answer: 3

Step-by-step explanation:

25 x (5 - 2) ➗ 5 - 12

Applying the rule of BODMAS

- Solve task in bracket first

25 x (5 - 2) ➗ 5 - 12

= 25 x (3) ➗ 5 - 12

= 75 ➗ 5 - 12

- Solve task of division next

75 ➗ 5 - 12

= 15 - 12

= 3

Thus, the answer is 3
