Answer:
-10
Step-by-step explanation:
-5x - 1 = -10x - 51
Add 10x to both sides.
5x - 1 = -51
Add 1 to both sides.
5x = -50
Divide both sides by 5.
x = -10

Sasha is collecting cans to recycle. When she collected 180 cans she knew she had reached 60% of her goal. How many more cans does Sasha need to collect to reach her goal?
Sasha needs to collect 120 more cans to reach her goal.
let us say the total goal is 100x
it is given that
when she collected 180 cans she knew she had reached 60% of her goal.
what is the percentage?it is made up of two words 'per' and 'cent' means it is the value out of a hundred.
60% of 100x= 60x
60x = 180(given)
x=3
total goal = 100x= 100*3=300
total goal left= 300-180=120
therefore, Sasha needs to collect 120 more cans to reach her goal.

As input 20 relates to two different outputs 40 and 50 the relation is not a function.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
We know a relation is a function if it is one to one implies every input relates to different output or many one as different inputs lead to the same output.
The given information is represented by a diagram has one-to-many relations as the input 20 leads to the same output 50 so this is a one-to-many relation and not a function.

The value of a home in 2015 was $400,000. Its value has been doubling each decade.
1. If v is the value of the home, in dollars, write an equation for v in terms of d, the number of decades since 2015.
Complete the equation below
v = _______________
Use d as your variable.
Use the ^ symbol to represent an exponent.
For example: 52 should be typed as 5^2
Answer:
[tex]v = 400000(2^\wedge d)[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Value = \$400000[/tex]
[tex]Rate = doubles[/tex] per decade
Required
Determine the equation of the function
The information given shows that the function is exponential and will be calculated using:
[tex]v = ab^d[/tex]
Where:
a = Initial Value = 400000
b = rate = 2
d = number of decades
v = the current value of the home
So, we have:
[tex]v = 400000* 2^\wedge d[/tex]
[tex]v = 400000(2^\wedge d)[/tex]
The equation that represents the value of the home is v = $400,00(2^d).
What is the equation that represents the value of the home?
The home is appreciating in value. This means that the price of the house is increasing with the passage of time.
The formula that can be used to represent the appreciation is:
FV = P (1 + r)^n
FV = Future value P = Present value R = interest rate N = number of yearsv = $400,000(2^d)

Aviva deposited some amount of money at a 4% annual interest rate into her bank account. The money was left in the account for 18 months, and she did not make any more deposits.
If Aviva's money earned $240 interest after 18 months, how much money did she deposit into the account?
The amount of money that was deposited by Aviva into her bank account is $4,000.
Given the following data:
Interest rate = 4% = 0.04.Simple interest = $240.Time = 18 months.Conversion:
12 months = 1 year.
18 months = 1.5 year.
To determine the amount of money that was deposited by Aviva into her bank account:

In one hour a machine can make
500 nuts
or
840 bolts.
At 2 pm the machine starts working.
It makes 750 nuts and then changes to making bolts.
How many bolts will the machine make by 8.00 pm?
Answer:
3780 bolts will be made by 8pm
Step-by-step explanation:
One Hour : 500 nuts or 840 bolts
Divide by 2
30 minutes : 250 nuts or 420 bolts
750 nuts : 500 + 250 = 750
so the machine took 1 hour and 30minutes
14:00 it started (2pm)
15:30 it switched to bolts
20:00 (8pm)
4 hours and 30minutes to get to 8pm
840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made

16: Find the coordinates of the foci and the vertices, the eccentricity, the length of the latus rectum of the Hyperbola y^2-16x^2=1.
Answer:
Foci [tex](0,\pm\frac{\sqrt{17}}{4})[/tex]
Vertices:[tex](0,\pm 1)[/tex]
Eccentricity, e=[tex]\frac{\sqrt{17}}{4}[/tex]
Length of latus rectum=[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
We are given that
[tex]y^2-16x^2=1[/tex]
[tex]y^2-\frac{x^2}{(\frac{1}{4})^2}=1[/tex]
The equation of hyperbola is along y-axis because y is positive
Compare the equation with
[tex]y^2/a^2-x^2/b^2=1[/tex] (Along y-axis)
We get
a=1, b=1/4
[tex]a^2+b^2=c^2[/tex]
[tex]1+\frac{1}{16}=c^2[/tex]
[tex]\frac{16+1}{16}=c^2[/tex]
[tex]c^2=\frac{17}{16}[/tex]
[tex]c=\pm \frac{\sqrt{17}}{4}[/tex]
Therefore,
The coordinates of foci=[tex](0,\pm c)=(0,\pm\frac{\sqrt{17}}{4})[/tex]
The coordinated of vertices=[tex](0,\pm a)=(0,\pm 1)[/tex]
Eccentricity, e=c/a
[tex]e=\frac{\frac{\sqrt{17}}{4}}{1}=\frac{\sqrt{17}}{4}[/tex]
Length of latus rectum=[tex]\frac{2b^2}{a}[/tex]
Length of latus rectum=[tex]2\times \frac{1}{16}=\frac{1}{8}[/tex]

Step-by-step explanation:
Points ( -3,5 )( 6,-4 )
You use the slope formula to find the slope.
Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.M = Y2 - Y1 over
X2 - X1
Which is -4 - 5
6 - -3 = -9/9 = -1
The slope is -1
Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )
And plug them in
-4 = -1(6) + b
-4 = -6 + b
+6 +6
2 = b
The equation will be y = -1x + 2
