Mathematics

Answer:

(x,y) = (2,3)

Step-by-step explanation:

y=5x-7                  (i)

-3x-2y= -12          

-(3x+2y)= -12

3x+2y= 12            (ii)

By putting the value of y from (i) in (ii)

3x+2(5x-7)=12

3x+10x-14=12

13x=12+14

13x= 26

x = \frac{26}{13}

x= 2

By putting the value of x in (i)

y= 5(2)-7

y= 10-7

y= 3

(x,y) = (2,3)

If f(x)=√4x+9+2, which inequality can be used to find the domain of f(x)?
tatiyna
  • y=√4x+9+2
  • y=√4x+11

As it's a square root the underroot value must be greater than or equal to 0

So

let's find out the domain

  • √4x+11≥0
  • 4x+11≥0
  • 4x≥-11
  • x≥-11/4

Domain

  • [-11/4,oo)

If A and B are supplementary angles and A is four times as large as ​B, find the measures of A and B.
lora16 [44]

Answer: Angle A= 135 degrees and Angle B= 45 degrees

Step-by-step explanation:

Supplementary means two angles added together to make 180.

Angle A= 3x  and Angle B= x

So 3x +x =180

4x=180 divide both sides by 4

x =45

So Angle A = 3 times 45 =135 degrees

Angle B= the value of x which is 45 degrees
