help :D i don’t understand number 8 or 9
Answer:
If the rate of change is -3, just subtract -3 from 14 (or make the equation to help you).
_________________________________________________________
The equation for the first one is:
y = -3x + 14
When you plug in the x values, you get the y values:
(-2, 20), (1, 11), (3, 5), (4, 2), (6, -4)
For the second one, the start value is 2, meaning that is is y. This means that when 2 is plugged in for y, the result is 0 (x). Now we can make the equation:
y = 0.4x + 2
When you plug the x values in, you get the y values:
(-1, 1.6), (1, 2.4), (4, 3.6), (5, 4), (10, 6)

The battery life for Bruhier's cell phone is longer when he has fewer apps running. When only one app is running, the battery will last for
16 hours. When four apps are running, the battery will only last for 4 hours.
This situation represents
variation.
The constant of variation, k, is equal to
If eight apps are running, Bruhler's battery will last for 4 hours
Answer:
inverse, 16, 4
Step-by-step explanation:
The constant of variation when eight apps are running, battery lasts for 4 hours is 32.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The battery life varies inversely with the number of apps running
The battery life is denoted by b
and the number of apps is denoted by a
then
[tex]\rm b\; \alpha \; (1/a)\\\\b = k /a[/tex]
here k is the proportionality constant
The battery lasts for 16 hours when the apps opened is 1
The battery lasts for 4 hours when the apps opened is 4
16 = k
The constant of variation when eight apps are running, battery will last for 4 hours
[tex]\rm 4 = k /8[/tex]
k = 32

A triangle has sides with lengths of 72 millimeters, 90 millimeters, and 54 millimeters. Is it a right triangle?
Answer:
Yes, it is a right triangle.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is the hypotenuse so c^2 would be 90.
72^2+54^2=90^2
72 and 54 can be either a or b.
Solve for all exponents: 5184+2916=8100.
That equation is true, so the triangle is a right triangle.

Find the argument of the complex number -3–9 in the interval 0°< ϴ < 360°,
rounding to the nearest tenth of a degree if necessary.
Answer:
[tex]\theta=251.6^\circ[/tex]
Step-by-step explanation:
Complex Numbers
They are expressed as the sum of a real part and an imaginary part:
[tex]Z = a+b\mathbf{ i}[/tex]
Complex numbers can also be expressed in polar form:
[tex]Z = r(\cos\theta+\sin\theta \mathbf{ i}) = r. cis(\theta)[/tex]
Where r is the modulus of the complex number and θ is the argument.
The argument can be calculated by:
[tex]\displaystyle \tan\theta=\frac{b}{a}[/tex]
The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.
The complex number is given as:
[tex]Z = -3 -9\mathbf{ i}[/tex]
Here: a=-3, b=-9
Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).
[tex]\displaystyle \tan\theta=\frac{-9}{-3}[/tex]
[tex]\displaystyle \tan\theta=3[/tex]
[tex]\theta=\arctan(3)[/tex]
The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
[tex]\mathbf{\theta=251.6^\circ}[/tex]

I need help on this one. it says solve for w. and it says w-8=32. will someone help plz thx.
Answer:
w= -4
Step-by-step explanation:
First we know 8 x 4 is 32 so then we make the 8 negative
and divide -8 by 32 which is -4
You can check it by doing -4 x -8 which is 32!
Remember-
1. When you multiply two negatives it equals a positive.
2. You can check by plugging -4 where w is then solving.
3. If there is a subtraction next to a number (w-8) then whichever number the subtraction sign is in front of is negative.
4. If a variable is next to a number it means to multiply the variable by the number.

Step-by-step explanation:
determine whether the relation is a function. if the relation is a function determine whether it is linear or not linear
Answer:
We conclude that the relation is a function but it is not a linear function.
Step-by-step explanation:
The given table represents a function because each input or x-value is related to exactly one output or y-value.
In other words, there is no repetition of 'x' values. This indicates that the given relation in the table represents a function.
In order to check whether the function is linear or not linear, we need to check how x and y values change.
The table indicated that x increases by 2, now we need to determine whether the y-values increases at a constant rate or not. For this, we need to find the first difference between y-values.
-3 - (-8) = 5
3 - (-3) = 6
7 - 3 = 4
As the first difference between the consecutive y-values is not constant, meaning that y-values do not increase at a constant rate as x-values increase by 2.
Thus, it is not a linear function,
Therefore, we conclude that the relation is a function but it is not a linear function.
