lin's dad bought a tablet. he pays the same amount each month for a subscription to a movie streaming service.the graph represents how much money he spent,y, for the tablet and x months of the service. Which graph corresponds to this situation?
Answer: Graph 1
Step-by-step explanation:
At 0 months, Lin's dad had already spent money to buy the tablet so the line should not start at 0. That rules Graphs 4, 5 and 6 out.
He pays the same amount every month so the movement from a point in the x axis to represent a month, should tally with a movement in the y axis that will be equal each time. This rules out Graphs 2 and 3 as the movements on Y are not equal on the line.
This leaves Graph 1 which means that Lin's dad paid $10 for the tablet and then pays $5 every month for a subscription to a movie streaming website.
In this exercise, we have to recognize the best graph that corresponds to what is treated in the text, that is, the graph that best corresponds to a monthly fee, in this way we find that it is:
Graph 1
First, we are dealing with finances in this way, we have that a tablet has already been purchased so our chart will not start at the null point (x=0) but from the value of the purchased item. In this way, we know that graphics 4, 5 and 6 must be excluded.
In addition to the purchased item, we know that the monthly fee is the same amount every month as long as this program exists so the movement from a point in the x axis to represent a month, should tally with a movement in the y axis that will be equal each time. This rules out graphs 2 and 3 as the movements on Y are not equal on the line.
This leaves graph 1 which means that Lin's dad paid $10 for the tablet and then pays $5 every month for a subscription to a movie streaming website.

B) Acute
A) Right
C) Obtuse
Hi!
Your answers should be : 1. Obtuse | 2. Acute | 3. Obtuse
Here's a little tip for you to remember if you cant get an answer off of brainly: if its 90ft (or degrees or what ever you want to call it) then its right, if its over 90ft its Obtuse, and if its under 90ft its Acute.
Hope this helps!

Solve the equation for x.
-7(x - 2) + 5(3 - x) = 4x - 3
Answer:
x=2
Step-by-step explanation:
-7x+14+15-5x=4x-3
-12x+29=4x-3
-12x-4x=-29-3
-16x=-32
x=-32/-16
x=2
Answer: x=2
Step-by-step explanation:
Simplify the equation
-12+29= 4x-3
Subtract 29 from both sides
12x=4x-32
Subtract 4x from both sides (Simplify)
-16x=-32
Divide both sides by -16
x=2

If f(x)=2x(With an exponent of 2) -3, find f(-2)
[tex]f\left(x\right)=2x^2-3f ( x ) = 2 x 2 − 3 find f\left(-2\right)f ( − 2 ).[/tex]
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
f(-2) = 5

Answer: thas really confusing
Step-by-step explanation:
A person places $4760 in an investment account earning an annual rate of 1.6%, compounded continuously. Using the formula V=PertV = Pe^{rt}V=Pert, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 7 years.
Answer:
$5324.12Step-by-step explanation:
Given that the principal p= $4760
rate r= 1.6% 1.6/100 =0.016
time t= 7years
by applying the expression
[tex]V = Pe^{rt}[/tex]
We have
[tex]V = 4760e^{0.016*7}\\\\ V=4760e^{0.112}\\\\ V=4760*1.11851286065\\\\ V=$5324.12[/tex]
Hence after 7 years the money in the account will be $5324.12

Answer:
7 = 7x - 48
Step-by-step explanation:
Use point slope formula: y - y1 = m(x - x1)
Find slope:
(8 -(-6)) / (8 - 6)
14/2
m = 7/1
Subsitute x1 and y1, solve for y.
y - 8 = 7(x - 8)
y - 8 = 7x - 56
y = 7x - 48

Point F is on line segment EG. Given FG = 3x – 5, EF = x
, and
EG = 5x – 8, determine the numerical length of FG.
Answer:
3
Step-by-step explanation:
the whole line equals
5x-8 as well as x+3x-5
since it equals both we know the equation is
5x-8=x+3x-5 simplify to 4x-5
5x-8=4x-5
-5x. -5x
-8=-1x-5
+5. +5
-3= -1x
-/. -/
3=x
we now can double check our work by putting 3 everywhere the x is
EG =7
FG= 4
making EF 3
