There is $500 in Holly's bank account. She takes out $50 from her account each month but doesn't put money back in. What is the slope/rate? *
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptGiven that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
EXTRA BONUS!
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form
[tex]y = mx+b[/tex]
y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500

what are the steps for solving
6x-1=-x+9
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7
I hope this helps have a great day!!!H varies directly to the cube of c.
When H = 40, C = 2.
(a) Express H in terms of c.
Answer:
H in terms of c is H = 5c³.
Step-by-step explanation:
Given that:
H = 40 and c = 2
H varies directly to the cube of c.
Which means that,
H ∝ c³
Let,
k be the proportionality constant.
H = kc³
Putting H=40 and c=2
[tex]40=k(2)^3\\40=k(8)\\40=8k\\8k=40[/tex]
Dividing both sides by 8,
[tex]\frac{8k}{8}=\frac{40}{8}\\k=5[/tex]
Now,
H in terms of c.
H = 5c³
Hence,
H in terms of c is H = 5c³.

Answer:
The entire race is 26.20 miles long.
Step-by-step explanation:
Given that:
Sam is 18.34 miles in the race.
This length represents the 70% of the entire length of the race.
Let,
x be the total length of the race.
70% of x = 18.34
[tex]\frac{70}{100}x=18.34\\[/tex]
0.7x = 18.34
Dividing both sides by 0.7
[tex]\frac{0.7x}{0.7}=\frac{18.34}{0.7}\\x=26.20[/tex]
Hence,
The entire race is 26.20 miles long.
There are 31 pink beads and 15 purple beads on Violet's necklace. What is the ratio of the number of beads to the number of pink beads?
Answer:
The ratio of number of purple beads to the number of pink beads is: 15:31
Step-by-step explanation:
Number of pink beads = 31
Number of Purple beads = 15
We need to find ratio of number of purple beads to the number of pink beads
So, The ratio of number of purple beads to the number of pink beads is:
Number of purple beads : Number of pink beads
15 : 31
Since it cannot be simplified further, So
The ratio of number of purple beads to the number of pink beads is: 15:31

Which of the following equations best represents the line of best fit for the data in the scatterplot?
Answer:
the answer is b bc the line is positive
Step-by-step explanation:
The equation that best represents the line of best fit is -
y = (1/2)x - 1
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the line of best fit for the data in the scatterplot.
The line passes through the points -
(0, - 1) and (2, 0).
Then, the slope will be -
m = 1/2
and the [y] - intercept is -1. So the equation that best represents the line of best fit is -
y = (1/2)x - 1
Therefore, the equation that best represents the line of best fit is -
y = (1/2)x - 1

The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2,200 people enter the fair and $5,050 is collected. How many children and how many adults attended?
Given :
The admission fee at a small fair is $1.50 for children and $4.00 for adults.
On a certain day, 2,200 people enter the fair and $5,050 is collected.
To Find :
How many children and how many adults attended.
Solution :
Let, number of children and adults attended are c and a.
So, c + a = 2200 ....1)
Now, fair collected is given by :
1.5c + 4a = 5050 ....2)
Putting value of a from equation 1) to 2), we get :
1.5c + 4( 2200 - c ) = 5050
1.5c - 4c = 5050 - 8800
2.5c = 3750
c = 1500
a = 2200 - 1500
a = 700
Therefore, 1500 children and 700 adults attended the fair.
plz help me find answer. what are the coordinates of slope when y= x/1–x² when dy/dx=1
Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x²
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).

Solve the Equation: 2(6b + 1) = 4(b-5)-2 halp me pls, thank you
Answer:
B= -3
Step-by-step explanation:
So first distribute what you can
12b+2=4b-20-2
Now combine like terms
12b+2=4b-22
Now subtract 2 on both sides
12b=4b-24
Now subtract 4b on both sides
8b=-24
Now divide 8 on both sides
b= -3

which of the following is geometric sequence?
Answer:
Choice C
Step-by-step explanation:
A geometric sequence is usually one that multiply or divide to get to the next number in the sequence. So let's go through them to see which one gets multiplied since all of the choices are increasing.
Choice A:
[tex]1^{+3},4^{+1},5^{+4},9^{+5},14[/tex]
Nope that's not what we're looking for.
Choice B:
[tex]3^{+3},6^{+3},9^{+3},12^{+3},15[/tex]
This would be a perfect arithmetic sequence but not the type of sequence we are looking for.
Choice C:
[tex]6^{*3},18^{*3},54^{*3},162[/tex]
Yes! See how this one is multiplying by 3 and not adding or subtracting.
Choice D:
[tex]3^{+2},5^{+3},8^{+5},13^{+7},21[/tex]
Nope this is not it either.

The expression -320+15y represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute. What was the depth of the submarine after 15 minutes?
Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
