Answer:

Elga's age be 49 years

Step-by-step explanation:

Let Elga's age be x years

Then, Alvin's age will be (x - 6) years

The sum of their ages is 92

Therefore,

x + (x - 6) = 92

x + x - 6 = 92

2x - 6 = 92

2x = 92 + 6

2x = 98

x = 98 /2

x = 49 years

Hence,

Elga's age be 49 years

Simplify without using the calculator or the sin tables.

katovenus [111]

Answer:

1/8

Step-by-step explanation:

sin²(π/8) − cos⁴(3π/8)

Use power reduction formulas:

1/2 (1 − cos(2×π/8)) − 1/8 (3 + 4 cos(2×3π/8) + cos(4×3π/8))

Simplify:

1/2 (1 − cos(π/4)) − 1/8 (3 + 4 cos(3π/4) + cos(3π/2))

1/2 (1 − √2/2) − 1/8 (3 + 4 (-√2/2) + 0)

1/2 − √2/4 − 1/8 (3 − 2√2)

1/2 − √2/4 − 3/8 +√2/4

1/2 − 3/8

1/8

List the steps that should be used to solve the equation f(x) = g(x) by graphing when f(x) = (1/2)² - 3 and g(x) = 3x + 5?

jolli1 [7]

value of x is: $x=\frac{-31}{12}$

Step-by-step explanation:

We need to solve the equation f(x)=g(x)

where $f(x)=(\frac{1}{2})^2-3$

and $g(x) = 3x + 5$

Solving to find f(x)=g(x)

Putting values of f(x) and g(x)

$f(x)=g(x)\\(\frac{1}{2})^2-3=3x + 5\\\frac{1}{4}-3=3x + 5\\Subtarct\,\,5\,\,on\,\,both\,\,sides:\\\frac{1}{4}-3-5=3x + 5-5\\\frac{1}{4}-8=3x\\Taking\,\,LCm\,\,on\,\,left\,\,side\\\frac{1-8*4}{4}=3x\\\frac{-31}{4}=3x\\Divide\,\,both\,\,sides\,\,by\,\,3\\x=\frac{-31}{4*3}\\x=\frac{-31}{12}$

So, value of x is: $x=\frac{-31}{12}$

The graph will be a straight line x= -2.58 or x = -31/12

What are the answers??? Please help!!!

Remember when you see those two signs next to each other its “kao” which is keep add opposite so for b its 6-(-3) but you do keep add opposite so now it’s 6+3=9. for c it’s -2-(-5) and we still do kao which now it’s -2+5 different signs you subtract so now it’s 3 we always keep the sign of the higher variable and 5 is positive so the answer is positive.
