pLease solve it again but that's answer is 8
Answer:
k = 3
Step-by-step explanation:
g(x) is 3 units higher than f(x), so k = 3.
Answer:
- Part 2 - ∠EGF = 105°
- Part 3 - ∠D = 65
<h3>________________________________________________</h3>
Step-by-step explanation for Part-2:
<u>We know that:</u>
- ∠EFG = 32°
- ∠AEG = 137°
- ∠EFG + ∠FGE + ∠GEF = 180°
<u>Work:</u>
- ∠EFG + ∠FGE + ∠GEF = 180°
- 32 + ∠FGE + (180 - 137) = 180°
- => 32 + ∠FGE + 43 = 180°
- => 75 + ∠FGE = 180°
- => ∠FGE = 180 - 75
- => ∠FGE = ∠EGF = 105°
Hence, the measure of ∠EGF is 105°.
<h3>________________________________________________</h3>
Step-by-step explanation for Part-3:
<u>We know that:</u>
- CD = CA
- This triangle is an isosceles triangle.
- ∠D = ∠A
<u>Work:</u>
- 50 + ∠D + ∠A = 180
- => ∠D + ∠D = 130
- => 2∠D = 130
- => ∠D = 130/2
- => ∠D = 65
Hence, the measure of ∠D is 65°

When I add or subtract polynomials, the degree adding
together too?
Ex: 5X^3-2X^2+7X^2, the degree staying 3 or 2? Or we add them?
Answer:
5X^3-2X^2+7X^2
5 x ^3 + 5 x^2
Adding polynomials: simply add the like terms together. Like
terms are terms with the same variables and exponents.
<span>
Subtracting polynomials: reverse the sign of each term
(in other words turn "+" into "-", and "-" into
"+"), then proceed to addition.</span>
Do not add the exponents.
Answer:
0.08*x + 0.09*(9000-x) = 750 dollars
0.08x + 810 - 0.09x = 750
-0.01x = 750 - 810 = -60 ====> x = %28-60%29%2F%28-0.01%29 = 6000.
Answer. $6000 was invested at 8%. The rest 9000-6000 = 3000 dollars were invested at 9%.
Check. 0.08*6000 + 0.09*3000 = 480 + 270 = 750 dollars. ! Correct !
have a great day
hope this help
