Answer:

x = 10

Step-by-step explanation:

=> 4x + 1 + 2x = 61

=> 6x = 61 - 1

=> 6x = 60

=> x = 60/6

=> x = 10

<u>Hence</u><u> </u><u>the</u><u> value</u><u> of</u><u> x</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u> </u><u>.</u>

Answer:

1) 65\textdegree

2) 44\textdegree

3) 107\textdegree

4) 82\textdegree

Step-by-step explanation:

1) Since the whole angle is 180\textdegree, and to find the other angle, which is labeled as x, you subtract 115\textdegree from 180\textdegree:

180 - 115 = 65

x = 65\textdegree

2) Since you already have two angle measures 46\textdegree and 90\textdegree, you add them up and subtract it from 180\textdegree to get the angle measure for x:

46 + 90 = 136

180 - 136 = 44

x = 44\textdegree

3) Same thing from number 1. Subtract 73\textdegree from 180\textdegree:

180 - 73 = 107

x = 107\textdegree

4) Same thing from number 2. Add 52\textdegree and 46\textdegree and subtract it from 180\textdegree:

52 + 46 = 98

180 - 98 = 82

x = 82\textdegree

Using substitution method 4x -2y = 18 -4x+2y= -18
dedylja [7]

x= 9
y= 9

4x -2y= 18.................equation 1

-4x + 2y= -18...............equation 2

From equation 1

4x= 18 + 2y

x= 18 + 2y/4

substitute 18+2y/4 for x in equation 2

-4(18+2y/4) -2y= 18

-(18+2y)-2y= 18

-18-2y-2y= 18

-18+4y= 18

4y= 18+18

4y= 36

y= 36/4

y= 9

Substitute 9 for y in equation 1

4x-2y= 18

4x-2(9)= 18

4x-18= 18

4x= 18+18

4x= 36

x= 36/4

x= 9

Hence the value of x is 9 and the value of y is 9

Consider the functions f(x) = 2x + 1 and g(x) = x^2 − 10 What is the value of f[g(3)]?
HACTEHA [7]

Answer:

-1

Step-by-step explanation:

Tip: Remember to always start from the inside, which would be g(3), in this case.

The first step in solving this problem is to solve for g(3).

To accomplish this, you must substitute 3 for x into the given equation g(x) = x^2 - 10

  • g(3) = 3^2 - 10
  • g(3) = 9 - 10
  • g(3) = -1

The next step is to substitute the answer of g(3), -1, for x in the given equation f(x) = 2x + 1.

Because the equation is asking for f[g(3)], it becomes f(-1) because g(3) = -1.

  • f(-1) = 2(-1) + 1
  • f(-1) = -2 + 1
  • f(-1) = -1

Therefore, f[g(3)], or f(-1), equals -1
