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%.
Answers
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]

solve for x: -(10+3x)=44
Answers
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

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.

8x2 – 4x = 363
Answers
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
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)
Answers
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)

A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape? ROUND to the nearest HUNDREDTH. I need answers quick
Answers
Answer:
7.900 cm
Step-by-step explanation:
The computation of the diameter after using the tape is given below:
Since the circumference is 14.8 cm
And it would be decrease by 2.4 cm
So, the new circumference is
= 14.8 - 2.4
= 12.4 cm
Now the radius is
= 12.4 ÷ π
= 3.95
And, the diameter is
= 3.95 × 2
= 7.900 cm
Solve for b. 5b + 8 - 2b = 7b. A 2 B.4/5 C.4/7 D.1/2
Answers
Answer:
b=2
Step-by-step explanation:
5b + 8 - 2b = 7b
Combine like terms
3b+8 = 7b
Subtract 3b from each side
3b+8-3b = 7b-3b
8 = 4b
Divide each side by 4
8/4 = 4b/4
2 =b
Answer:
b=2
Step-by-step explanation:
Simplifying
5b + 8 + -2b = 7b
Reorder the terms:
8 + 5b + -2b = 7b
Combine like terms: 5b + -2b = 3b
8 + 3b = 7b
Solving
8 + 3b = 7b
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-7b' to each side of the equation.
8 + 3b + -7b = 7b + -7b
Combine like terms: 3b + -7b = -4b
8 + -4b = 7b + -7b
Combine like terms: 7b + -7b = 0
8 + -4b = 0
Add '-8' to each side of the equation.
8 + -8 + -4b = 0 + -8
Combine like terms: 8 + -8 = 0
0 + -4b = 0 + -8
-4b = 0 + -8
Combine like terms: 0 + -8 = -8
-4b = -8
Divide each side by '-4'.
b = 2
Simplifying
b = 2
