Irma has a total point of -8 now.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given that, Irma is just learning to play the Happy Fairies video game.
In the game, based on the taking care of fairies, players gain and lose points.
Initial point Irma had = -5 points
Fairy fell over in the wind and she got -3 points.
Final point = -5 + -3
= -5 - 3
= -8
Hence the total points now is -8.

which pair of terms are not like terms?
A. 4a and 7a
B. 3p^2q and -p^2q
C. 2mn and mn^2
D. -x and 3x
Answer:
C.
Step-by-step explanation:
Like terms must have exactly the same variables and exactly the same exponents.
In C., you have mn and mn^2. That makes the variable parts not the same, so they are not like terms.
Answer: C.
Write the expression as a power and evaluate it. 8*2^7
Answer:
1024
Step-by-step explanation:
The expression can be written as [tex]8 * 2^7[/tex]
What is power?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
8*2^7
The above expression can be written as
[tex]=8 * 2^7[/tex]
= 8 x 128
= 1024.
Hence, the expression can be written as [tex]8 * 2^7[/tex]

proves that the sum of
5 consecutive natural numbers is divisible by 5
Answer:
n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.
Step-by-step explanation:
Answer:
Natural numbers are simply positive integers. For now, refer to the middle number (the third number), as x. Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2. Simply add all these numbers to get 5x, a number that is divisible by 5. As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.

Number 1
m = (y2 - y1)/(x2 - x1)
m = (3 - 1)/(5 - 2)
m = 2/3 POSITIVE
Number 2
m = (y2 - y1)/(x2 - x1)

Answer:
f(x)= -1/2x+1
Step-by-step explanation:
The slope is negative because the graph goes up then to the left, making it negative. The slope is also 1 half because the slope is measured by rise over run. It rises once, then goes to the left twice. 1/2. It's also plus 1 because the graph cross the y-intercept at positive 1.
Rewrite the following in ascending order.
(a) -3/8, 5/-12, -7/16, -13/18, 11/-24
Answer:
⇛-13/8 , -11/24, -7/16, -5/12 , -3/8
Step-by-step explanation:
Given numbers are -3/8 , 5/-12, -7/16, -13/18 , 11/-24
The can be written as -3/8, -5/12, -7/16, -13/18, -11/24
The denominators = 8,12,16,18,24
LCM of the denominators = 144
-3/8 = (-3/8)×(18/18) = -54/144
-5/12 = (-5/12)×(12/12) =-60/144
-7/16 = (-7/16)×(9/9) = -63/144
-13/18 = (-13/18)×(8/8) = -104/144
-11/24 = (-11/24)×(6/6) = -66/144
Ascending order of the numbers
= -104/144 , -66/144, -63/144, -60/144, -54/144
-13/8 , -11/24, -7/16, -5/12 , -3/8
Drag each tile to the correct box. Complete the sequence for deriving the quadratic formula using the quadratic equation in standard form, .
Answer:
see the picture
Step-by-step explanation:
By the below figure (6) is the initial equation
(1) next added (b/2a)^2 on both sides to make it whole square on left side which gives (4) in (4) both terms are added on the right side to make it (5)
then square root on both sides gives (2) and now taking b/2a to the right side gives the final quadratic formula (3)
We can obtain the quadratic formula from completing the square method as shown.
The quadratic formula is derived from the completing the square method as follows;
Given the quadratic equation;
[tex]ax^{2} + bx + c =0[/tex]
Dividing through by a we have;
[tex]x^{2} + \frac{b}{a} + \frac{c}{a} = 0[/tex]
Adding half of b to both sides of the equation, we have;
[tex](x + \frac{b}{a}) ^{2} = \frac{-c}{a} + \frac{b^2}{4a^2}[/tex]
Taking LCM of the right hand side;
[tex](x + \frac{b}{2a})^{2} = \frac{b^2 - 4ac}{4a^2}[/tex]
Making x the subject of the formula;
[tex]x = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

Answer:
#5) Its line “k”
Well to solve this you need to know what negative slopes are.
They decrease from height from left to right
And also a slope is always calculated like this
rise -> run
Think of it like a bed.
You have to wake up which means you have to rise and then you run to do whatever it is you gotta do.
Rise is going vertical and run is going horizontal.
So for line K you have it because since its negative its -3/1 so technically its -3 rise(basically fall since its negative), 1 run (right).
#6) 1/2 is the slope of line N. Or (c)
Well n is a potsive slope so we can automatically remove a and b.
And we can count like this, it started from the orgin it looks like (but you can use any given point really) and then just follow it, rise 1 and run 2. Rise 2 and run 3 doesn’t work so it has to be 1.2 or (c)

I basically just have to find the angles but I also want to understand so if you could explain?
9514 1404 393
Answer:
c = 108°
d = 106°
Step-by-step explanation:
There are 2 basic rules involved here. From them, a number of others can be derived in order to simplify some calculations.
angles forming a linear pair are supplementary (total 180°)interior angles of a triangle total 180°The derived relations we can use in this problem are ...
vertical angles are congruentan exterior angle of a triangle is equal to the sum of the opposite interior angles__
cThe vertical angle to 78° is one of two remote interior angles with respect to exterior angle c. The other is the one marked 30°. That means ...
c = 78° +30* = 108°
__
dAngles d and 30° are two of the three angles in the largest triangle. The third is the vertical angle to 44°, so it is 44°. The sum of angles in that triangle is 180°:
d + 30° +44° = 180°
d = 180° -74° = 106°
the answer gzzydyyxggxggxxghyzyxycycgcycyc
Step-by-step explanation:
we start with the first and the third equations, as they have the same content structure.
we multiply the whole first equation by 2, so that the z terms become aligned, and then we add both equations :
-8x + 4z = 28
-2x - 4z = 22
--------------------
-10x + 0 = 50
x = -5
-2x - 4z = 22
-2×-5 - 4z = 22
10 - 4z = 22
-4z = 12
z = -3
y = x + z + 12
y = -5 - 3 + 12 = 4
