Indicate the equation of the given line in standard form.
Ganezh [65]
Since the slope stays the same as it's parallel, we have y=(3/4)x+b. Plugging (2,-1) in, we get -1=3*2/4+b=6/4+b=1.5+b. Subtracting 1.5 from both sides, we get -2.5=b and our equation being y=(3/4)x-2.5 (since in y=mx+b, y and x remain as variables)

If 6/10 is multiplied by a fraction less than 1,which of these would be an answer 6/10,1/2,3/2,or 5
Pavlova-9 [17]

If \frac{6}{10} is multiplied with a fraction less than 1, out of the given options \frac{1}{2} would be the answer.

Explanation:

  • First, we need to determine what a fraction lesser than 1 is. If the numerator is lesser than the denominator, the fraction will be lesser than 1 whereas if the denominator is higher than the numerator is would equal more than 1.
  • If \frac{6}{10} is multiplied with 1, we get the value \frac{6}{10}. Since the fraction must be lesser than 1, \frac{6}{10} cannot be an answer. So option 1 cannot be the answer.
  • The value of \frac{6}{10} is 0.6. If it is multiplied with any value lesser than 1, the resulting value cannot be higher than the value of 0.6. The value of the fraction \frac{3}{2} is 1.5 and the value of 5 are both greater than 0.6. So the third and fourth options cannot be the answer. So \frac{1}{2} is the answer.

HEY GUYS THIS IS MY FINAL MATH ASSIGNMENT OF THE YEAR... PLS JUST HELP ME FIND THE DOMAIN AND RANGE THANK YOU
Gnom [1K]

Answer:

domain: all real numbers (-∞,∞)

range: y ≤ 64

Step-by-step explanation:

since the domain is arn,

and range is the coordinates

coordniate (top or bottom-most point)

downward facing so the top

(2, 64)

since it is downward facing we use ≤ instead of ≥

y value is 64 (just as x is 2)

your answer is y ≤ 64

hope this helps:)
