Triangle E F G is shown. Angle G F E is a right angle. The length of G F is 3 and the length of E F is 4.6. Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.6 Over 3 EndFraction) m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction) m∠E = tan–1(StartFraction 4.6 Over 3 EndFraction)
Answer:
m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)
Step-by-step explanation:
Given the following
m<GFE = 90 degrees
GF = 3
EF = 4.6
The side opposite to m<E is GF
Adjacent side is EF
Using the SOH CAH TOA identity
tan theta = opp/adj
tan m<E =GF/EF
Substitute the given values
tan m<E = 3/4.6
m<E = tan^-1 (3/4.6)
Hence the required result is m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)

8x2 – 4x = 363
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4

Answer:
12 + x = 16 because x is 4
3x + y is 19 because 3x is 12 and y is 7
4y - 10 is 18 because 4y is 28

solve for x: -(10+3x)=44
Answer:
x=-18
Step-by-step explanation:
-(10+3x)=44
substitute the minus sign to the bracket
-10-3x=44
-3x=44+10
-3x=54
divide both sides by -3
so x=-18

Helene invested a total of $1,000 in two simple-interest bank accounts. One account paid 8% annual interest; the other paid 9% annual interest. The total amount of interest she earned after one year was $86. Enter and solve a system of equations to find the amount invested in each account. Enter the interest rates in order as given in the problem. (Hint: Change the interest rates into decimals first.)
at 9%.
Answer: -600 and 1600 were invested into the two accounts.
Step-by-step explanation:
x = amount invested in the first account.
y = amount invested in the second account.
You start off with this equation
[tex]x + y = 1000[/tex]
[tex]0.08x + 0.09y=86[/tex]
Subtract both sides by y.
[tex]x=1000-y[/tex]
Subsitude 1000 - x for x for the second equation.
[tex]0.08(1000-y)+0.09y=$86[/tex]
Use the distributive property to solve for y.
[tex]80-0.08y+0.09y=86[/tex]
[tex]80-0.01y=86[/tex]
[tex]6=-0.01y[/tex]
[tex]=-600[/tex]
Subsitude -600 for y in the first equation and solve for x.
[tex]x-600=1000[/tex]
[tex]x=1600[/tex]
-600 and 1600 were invested into the two accounts.

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.
