Answer:
y=130
Step-by-step explanation:
1) combine all like terms for the inside angles of the triangle
(3x-19) + (4x+8) + (x+7)3x-19+4x+8+x+78x-42) because the sum of all angles = 180 add that to the sum of all like terms
8x-4=180add 4 on both sides and divide both sides by 8this should be x=233) now you replace the x's with 23
(3(23) -19)69-19504) now we know that (3x-19)=50
5) take 180 and subtract 50
this is because y and (3x-19) creates a supplementary angle which also equals 1806) 180-50=130

Answers
The answer to this problem is 35 :)
Answer:
35
Step-by-step explanation:
(-2,-1) to (3,-1) is 5 units which is the length, and (-2,6) to (-2,-1) is 7 units which is the height, so using the formula for perimeter: length x height, 5 x 7 = 35

Lucy invested $19,000 in an account paying an interest rate of 3% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 8 years?
Answers
Answer: 24100
Step-by-step explanation:
The money in the account after 8 years is $24068.631.
Given that, principal=$19000 and the rate of interest=3%.
What is the formula to find the compound interest?The formula to find the compound interest is CI=A-P.
Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.
Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]
=19000[tex](1.03)^{8}[/tex]
=19000×1.26677008139
=$24068.6315464
=$24068.631
Therefore, the money in account is $24068.631.

g. If you are going 70.0 mi/hr, how many miles do you travel in 0.681 hours!
Answers
Answer:
47.67 miles (in 40.86 minutes or 40 minutes and 51.6 seconds)
Step-by-step explanation:
Simple. Multiply these values together to cancel out the quantity in the denominator (cross multiply).
0.681 * 70 = 47.67
let x be the distance in miles:
70.0/1 = x/0.681
0.681 * 70 = 1 * x
47.67 = 1 * x
47.67 = x
Which sequence of steps is a correct derivation of the difference quotient for f(x) = 3 – log x?
Answers
Answer:
Step-by-step explanation:
Where are the answer choices?
Still, it's possible to help you without your having shared those choices.
The "difference quotient" is defined as:
f(x + h) - f(x)
--------------------
h
where h represents an incremental (small) change in x.
Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).
Therefore the difference quotient is:
{3 - log (x + h)} - {3 - log x}
-------------------------------------
h
This can be simplified. In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x
and the difference quotient is
-log ( x + h) + log x
---------------------------
h
This can be rewritten as
log x - log (x + h) x x
--------------------------- , or (1/h)*log ------------ , or (1/h) log { ----------- }
h (x + h) x + h

Answer:
The expression are
[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]
and
[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]
Step-by-step explanation:
Generally from the diagram the energy change from state A to state B is
[tex].\ \ \Delta E_2 \ \ \ \ \ \ \ \ \Delta E_2 \\A \ \ \to \ \ \ C \ \ \ \to \ \ \ B\\[/tex]
Also
[tex].\ \ \Delta E_3 \ \ \ \ \ \ \ \ \Delta E_4 \\A \ \ \to \ \ \ D \ \ \ \to \ \ \ B\\[/tex]
So two expressions for the difference in internal energy between state a and state b are
[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]
and
[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]

9. ∠DEF and ∠FEG are complementary. m∠DEF = (3x − 4)°, and m∠FEG = (5x + 6)°.
Find the measures of both angles.
Answers
Answer:
29°61°Step-by-step explanation:
Complementary angles are two angles that add up to be 90 degrees.
We can write an equation and solve for x.
(3x - 4) + (5x + 6) = 90
~Combine like terms
8x + 2 = 90
~Subtract 2 to both sides
8x = 88
~Divide 8 to both sides
x = 11
Angle DEF:
3x − 4
3(11) - 4
33 - 4
29°
Angle FEG:
5x + 6
5(11) + 6
55 + 6
61°
Check:
29 + 61 = 90°
