Find three consecutive integers whose sum is -3.
Answer:
-2, -1, 0Step-by-step explanation:
Let the integers be:
n, n + 1 and n + 2Then we have the sum:
n + n + 1 + n + 2 = -33n + 3 = -33n = -6n = -2So the numbers are: -2, -1, 0

Find all polar coordinates of point P where P = (9,pi divided by 5).
Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
A triangle has exactly three sides. Prove the conditional by proving the contrapositive. If a polygon has more than three sides, then it is not a triangle. Contrapositive: If _____, then _____. Since ______, the contrapositive is _____, the original statement must be _____.
Answer:
Contrapositive: if a polygon does not have more than 3 sides, then it is a triangle. Since it is a true statement, the contrapositive is a true statement, the original statement must be a true statement.
Step-by-step explanation:
Original statement: if a polygon has more than three sides, then it is not a triangle.
Let P = a polygon has more than three sides
Let Q = it is not a triangle
Conditional statement: If P, then Q
Contrapositive statement: if not P, then not Q.
If a conditional statement is true, then the contrapositive is true.
If a contrapositive statement is true, then the contrapositive is true

Answer:
8°
Step-by-step explanation:
The laws of angles say that angles opposite the vertex (as in this case) are equal
So
(7x + 15)° = (9x - 1)°
let's remove the ° just so as not to get confused
7x + 15 = 9x - 1
To solve we must move the Xs on one side of the = sign and the free numbers on the other. For that, we must do the same operations on both sides. If we subtract from one, from the other also, and so on.
So we are going to substract 15
(7x + 15) - 15 = (9x - 1) -15
It result:
7x = 9x - 16
We are going to substract 9x
(7x) - 9x = (9x - 16) - 9x
It result:
7x - 9x = -16
-2x = -16
We are going to change the signs (ON BOTH SIDES)
2x = 16
x = 8
now we have the value of X
we substitute x in the equations
7(8) + 15 = 9(8) - 1
56 + 15 = 72 - 1
71 = 71
So, the angles are 71°
And the Value of X is 8°I need help fast please help

A belt and a wallet cost $42.7 belts and 4 wallets cost $213 find the cost of each item
Answer:
A belt costs $15 and a wallet costs $27.
Step-by-step explanation:
Let's mark price of a belt with x and price of the wallet with y. That leaves is with a system of equations:
x + y = $42
7x + 4y = $213
The goal when solving this system is to get rid of one of the variables. We can do that by multiplying first equation with -4:
-4x - 4y = -168
7x + 4y = 213
Now, we simply add these two equations up:
-4x - 4y + 7x + 4y = -168 + 213
3x = 45
x = $15
Now, we plug in x into any of the two starting equations to find y:
x+y=42
15 + y = 42
y = $27

Find the slope and the y-intercept of the graph of y - 3.5 = -2x
thanks if you help!!
Answer:
Slope is -2 and y intercept is 3.5
Step-by-step explanation:
Basically you change it into slope intercept form by adding 3.5 on both sides to get y by itself, then you have the slope and the y intercept.
In a Petri dish there are currently 1,235 bacteria. The growth rate of bacteria is 3.25% How many bacteria will be there in the dish after 5 hours
Answer:
....
Step-by-step explanation:
Answer:
1,436
Step-by-step explanation:
First multiply the growth rate by the number of hours.
3.25 x 5 = 16.25
Now multiply 1,235 by 100. = 123,500
And also multiply 1235 by the remainder percentage not being used(83.75)= 103,060.75
Now subtract 123,500 - 103,060.75 = 20,439.25
Divide this number by 100 = 204.3925 which is what 16.25% of 1,235 is.
1,235 + 204 = about 1,439 but since i rounded up a few times the answer is actually 1,435.6875 rounded up to 1,436

In Triangle BCD, BC=BD, and angle B =13x-35, angle C = 5x-19, angle D=2x+14. Find the measure of each angle
Answer:
[tex]B = 108[/tex]
[tex]C = 36[/tex]
[tex]D = 36[/tex]
Step-by-step explanation:
Given
[tex]B =13x - 35[/tex]
[tex]C = 5x - 19[/tex]
[tex]D=2x+14[/tex]
[tex]BC = BD[/tex]
Required
Determine the measure of each angle
The angles in a triangle sum up t 180. i.e.
[tex]B + C + D = 180[/tex]
Since [tex]BC = BD[/tex], then [tex]C = D[/tex]
[tex]B + C + D = 180[/tex] can then be rewritten as:
[tex]B + C + C = 180[/tex]
[tex]B + 2C = 180[/tex]
Substitute values for B and C
[tex]13x - 35 + 2(5x - 19) = 180[/tex]
Open Bracket
[tex]13x - 35 + 10x - 38 = 180[/tex]
Collect Like Terms
[tex]13x + 10x = 180 + 38 + 35[/tex]
[tex]23x= 253[/tex]
Divide both sides by 23
[tex]x = 11[/tex]
To get the measure of each angle, substitute 11 for x in the expressions of B, C and D
[tex]B =13x - 35[/tex]
[tex]B = 13 * 11 - 35[/tex]
[tex]B = 108[/tex]
[tex]C = 5x - 19[/tex]
[tex]C = 5 * 11 - 19[/tex]
[tex]C = 36[/tex]
[tex]D=2x+14[/tex]
[tex]D = 2 * 11 + 14[/tex]
[tex]D = 36[/tex]
The measure of m<B, m<C and m<D are 108, 36 and 46 respectively
What are triangles?From the triangle BCD, if BC=BD, then
m<C = m<D (Base angles are equal)
Given the following paramters:
m<C = 5x-19m<D = 2x + 14Hence;
5x - 19 =2x + 14
5x- 2x = 14 + 19
3x = 33
x = 11
m<B = 13x - 35
m<B = 13(11) - 35
m<B = 108 degres
m<C = 5x - 19
m<C = 55- 19
m<C = 36
m<D = 180 - 144
m<D = 36 degreees
Hence the measure of m<B, m<C and m<D are 108, 36 and 46 respectively
