what equation represents the line that passes through the points (7,15) and (-4,4)?
Answers
Equation of line is y = mx +b
Passing through (-3,7 )
X= -3, y= 7
plug in these
7 = -3m + b ... .Eq1
Also X = 4 , y= 10
10 = 4m + b ............... Eq 2
Solve Eq 1 and Eq 2 for m and b
m= 3/7
b= 58/7
Thus y =( 3/7) X + 58/7 is equation of line

What is Division method?
Division method is used to distributing a group of things into equal parts.
Given that;
Total length of rope = 20 yards
One piece = 1 3/4 = 7/4 yard
Now, Number of pieces of rope = 20 ÷ 7/4
= 80/7
= 11.43
= 11 and 3/7 pieces.
Thus, There are 11 3/7 pieces of rope which can cut from the rope.

What is the slope of the graph in decimal form.
Answers
The slope of the graph in decimal form is 1.08.
By geometry we know that a line can be constructed after knowing the location of two distinct points. Lines in explicit form are defined by slope and intercept, the former is calculated by the secant line equation and the intercept by solving a linear function.
If we know that [tex](x_{1}, y_{1}) = (4.2, 9.6)[/tex] and [tex](x_{2}, y_{2}) = (6.7, 12.3)[/tex], then the slope of the graph is:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m = \frac{12.3-9.6}{6.7-4.2}[/tex]
[tex]m = 1.08[/tex]
The slope of the graph in decimal form is 1.08.

A sequence has the recursive definition of f(1)=2/3, f(n)=f(n-1)×3/2 for n≥2
Right the first five terms of the sequence
Leave answers as fractions
Answers
Answer:
Step-by-step explanation:
[tex]f(1)=2/3\\f(2)=f(1)\times (3/2)=(2/3)\times(3/2)=1\\f(3)=f(2)\times (3/2) = 1\times (3/2) = 3/2\\f(4)=f(3)\times (3/2) = (3/2)\times (3/2) = 9/4\\f(5)=(f(4)\times (3/2) = (9/4)\times (3/2) = 27/8[/tex]
So the first five terms are 2/3, 1, 3/2, 9/4, 27/8.
The first five terms are 2/3, 1, 3/2, 9/4, and 27/8 if the f(1)=2/3, and f(n) = f(n -1)×(3/2); for n ≥ 2.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
It is given that:
f(1)=2/3,
f(n) = f(n -1)×(3/2); for n ≥ 2
Plug n = 2
f(2) = f(2 -1)×(3/2)
f(2) = f(1)×(3/2)
f(2) = (2/3)(3/2)
f(2) = 1
Similarly;
f(3) = 3/2
f(4) = 94/
f(5) = 27/8
The first five terms are 2/3, 1, 3/2, 9/4, and 27/8.
Thus, the first five terms are 2/3, 1, 3/2, 9/4, and 27/8 if the f(1)=2/3, and f(n) = f(n -1)×(3/2); for n ≥ 2.

How much does the refrigerator cost?
Answers
Answer: $535
Step-by-step explanation
He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):
So the formula for interest is
Interest = (principal ×interest rate × time for which the money was deposited) / 100
Interest = ?
Principal = $500
Interest rate = 7%
Time = 1 year
Now
Interest = (500 × 7 × 1) / 100
Interest = 3500/ 100
Interest = $35
So the refrigerater's cost = 500 + 35
Cost = $ 535

Jasmine's cell phone company charges her $35 a month for phone service plus 0.50 for each text message. Her
total bill for the month was $51.
Answers
Answer:
[tex]35+0.50t=51[/tex]
Step-by-step explanation:
Since the $35 is a one-time fee, 0.50 is the rate, t is the variable, and 51 is the total bill, we can form the equation:
[tex]35+0.50t=51[/tex]
Answer:
0.50t+35=51
Step-by-step explanation:
0.50 is the amount for each text message so it becomes 0.50t (0.50 × text message). This is added to the monthly cost which is 35 dollars (+35) the question wants an equation as the answer so (=51).

if you make $391 for 17 hours how much would you make in 13 hours
Answers
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.
