Explain this algebraic expression in your own words: 3x - y

Answers

Answer 1

Answer:

You have a number multiplied by the variable x, so three times some value x. then you have (-y) taking the value of 3x and subtracting the value of (y) from it. The expression depends on the values of x and y you plug into it.

Step-by-step explanation:

for example, 3(4) - (6) = 12-6 = 6

If two angles are supplementary and one of them is 30 , what is the measurement of the second angle? A. 180
B. 90
C. 60
D. 150

Answers

You just need to know the definition of suplementary angles. Two angles are suplementary if the sum 180°. So, you now can easily deduct that the unkonwn angle is such that when sumed to 30° the result is 180° => x + 30 = 180=> x = 180 - 30 => x = 150°. And the answer is the option D) 150.

Answer: Hello there!

If you have a line (with a plane angle of 180°) and a segment that cuts the line, the two angles generated by the line and the segment are supplementary, and the sum of them should be equal to 180°

if one of the angles is 30°, then the other angle should be:

180° - 30° = 150°

then the right answer is option D.

How many solutions does the following equation have (6x +12) =-18

Answers

( 6 x + 12 ) = -18

6 x + 12 = - 18

6 x = - 18 - 12

6 x = - 30

x = - 30 / 6

x = -5

only 1 solution

Solve each question for X , y=-9+x^2

Answers

so basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
$√(y+9)=x$

x= $√(y+9)$

y = -9 + x^2
y + 9 = -9 + 9 + x^2
y + 9 = x^2
√y+9 = √x^2
√y+9 = x
x = √y+9

√ is the square root symbol
