What is the x-coordinate in the solution of the system of equations y =
=-
I and 42
9y= -402
Answers
y = -2/3x
So we plug in y = -2/3x for the value of y in the equation we need to solve.
4x - 9(-2/3x) = -40 (9 • -2/3x = -6x)
4x - (-6x) = -40 Multiply together
4x + 6x = -40 Combine like terms
10x = -40 Isolate x
x = -4

Peyton invested $690 in an account paying an interest rate of 5.6% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 8 years?
Answers
Answer:
$1,080.
Step-by-step explanation:
Given that Peyton invested $ 690 in an account with an annual interest of 5.6% compounded monthly, and that he kept said money in his account for 8 years without withdrawing or adding any amount, to obtain the final amount of money that said account would have after 8 years. years of investment, the following calculation must be made:
8 x 12 = 96
X = 690 x (1 + 0.56) 96
X = 1,078.85
Thus, after 8 years of investment, the amount that Peyton's account will have will be $ 1,078.85, that is, $1,080 rounded to the nearest ten dollars.

What is the sum of the measures of the exterior angles of a polygon that has fifteen sides?
Answers
Answer:
The sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.
Step-by-step explanation:
The Exterior Angle Sum Theorem defines that the sum of the exterior angles of any convex polygon is 360°.Given that a polygon has 15 sides.
If the polygon is regular with 15 sides, it indicates that each exterior angle is
360°/15 = 24°
so the measure of each exterior angle of a 15 sided polygon is 24°.As the polygon has 15 sides, the sum of the measures of the exterior angles of a polygon will be:
15 × 24 = 360°Therefore, the sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.

y=4/x
y=-4x + 1
y= 5(x – 0.6)
Answers
Answer:
y=-4x + 1
y= 5(x – 0.6)
Step-by-step explanation:
y = -4x + 1 follows the linear equation of y = mx + b.
y = 5(x - 0.6) can be simplified into y = mx + b by distribution,
y = 5x - 3 which follows the linear equation of y = mx + b.

Answers
Answer: = 2 8/11
2 IS THE WHOLE NUMBER
8/11 IS THE FRACTION
Step-by-step explanation:
First
Convert any mixed numbers to fractions.
Then your initial equation becomes:
15/4÷11/8
Applying the fractions formula for division,
=15×84×11
=12044
Simplifying 120/44, the answer is
= 2 8/11
When [tex]3\frac{3}{4}[/tex] is divided by [tex]1\frac{1}{8}[/tex] we get the fraction 10/3.
To divide mixed fractions, we first convert them to improper fractions, and then perform the division.
Let's convert the mixed fractions into improper fractions:
[tex]3\frac{3}{4}[/tex]= (4× 3 + 3) / 4 = 15/4
[tex]1\frac{1}{8}[/tex] = (8 × 1 + 1) / 8 = 9/8
Now, we can divide the fractions:
(15/4) / (9/8)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(15/4) × (8/9)
30/9
The GCD of 30 and 9 is 3, so divide numerator and denominator by 3:

The measure of angle ABD 3pi/4 is radians. What are the approximate coordinates of D? Write your answer in the following format: (x,y) with no spaces. Round your answer to the nearest hundredth.
HELPPPPP
Answers
Answer: (-.71, .71)
Step-by-step explanation:
To find the approximate coordinates of point D, we need to consider the angle ABD that measures [tex]3pi/4[/tex]radians.
Since point B is the center of the circle with radius 1 and point A lies on the x-axis at (1, 0), we can calculate the coordinates of point D using trigonometry. First, let's find the coordinates of point B, which is the origin (0, 0). Since the angle ABD measures[tex]3pi/4[/tex] radians, we know that angle ABO is pi/4 radians (complementary angle to ABD).
Using trigonometry, we can find the x-coordinate of point D based on the angle ABO: x-coordinate of D = cos(pi/4) = cos(45 degrees) = 1/sqrt(2) ≈ 0.71 Similarly, using trigonometry, we can find the y-coordinate of point D based on the angle ABO: y-coordinate of D[tex]= sin(pi/4) = sin(45 degrees) = 1/sqrt(2) ≈ 0.71[/tex] Therefore, the approximate coordinates of point D are (0.71, 0.71).
