Answer: C) 5

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

2 + 12a − 7b + 9a + 14

In an expression each term is separated by a + sign or a - sign. A term can be a number, a variable, or a term multiplied by a variable or variables.

In this case there are five terms: 2; 12a; 7b; 9a and 14.

So, the correct option is c) 5.

Write parametric equations of the line with the equation 2x+3y=5
Veseljchak [2.6K]
We have
2x+3y=5

Step 1
find two points of the line
for x=0--------------> y=5/3     point (0,1.67)
for y=0 --------------> x=5/2    point (2.5,0)

The vector between two points is v =(2.5-0,0-1.67)=(2.5.-1.67)

Vector form: r=ro+tv----------> (2.5,0)+(2.5,-1.67)t

Parametric form 
x=2.5+2.5t
y=-1.67t

the answer is 
x=2.5+2.5t
y=-1.67t

X-7=-2x-5 can someone help me with the steps
natima [27]
X-7 - -2x-5

answer is 2/3 

X-7 + 2X= -2x-5+2x

3x-7= -5


3x-7+7= -5+7 (getting x alone)

3x=2 

divide by 3 to get x

3x/3 =2/3

x=2/3
