Answer:

-4a + 7a = + 3a

Find the value of r so the line that passes through each pair of points has the given slope.
3241004551 [841]

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

\frac{5-r}{6}=\frac{2}{3}

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

5 - r = 4

subtract 5 from both sides

-r=-1

multiply both sides by -1

r=1

Please help with last 2 domain and range
Strike441 [17]

Answer:

See below for answers and explanations

Step-by-step explanation:

Top left: Since y can't be greater than 0 but is equal to 0, then the range is (-∞,0] and the domain is (-∞,∞) since there are no domain restrictions

Top right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)

Bottom left: Since y cannot be less than 2 but equal to it, and x holds no domain restrictions, then the domain is (-∞,∞) and the range is [2,∞)

Bottom right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)

1. In which quadrant does θ lie given that sinθ>0 and cosθ<0?
expeople1 [14]

Answer:

\theta is in quadrant II

Step-by-step explanation:

Given

\sin(\theta)  > 0 and \cos(\theta)  < 0

Required

Where is \theta

\sin(\theta)  > 0 and \cos(\theta)  < 0 imply that

\theta is in quadrant II

Because that is only quadrant where \sin(\theta)  > 0 and \cos(\theta)  < 0 exist.
