PLEASE HELP ME!!! -3x + 12 < 18
Isabel began training for a marathon by running 63 miles during her first week. Each week, she increased the distance she ran by 10% of the previous week's distance.
Which function represents the number of miles she ran during the nth week?
Answer:
10% of 63 is 6.3 so 63+6.3=69.3
Step-by-step explanation:
If g(x) = 1/2x + 9, what is (g) 6
Answer:
g(6) = 12
Step-by-step explanation:
g(x) = 1/2x + 9
To find g(6), replace x with 6 in the expression and evaluate it.
g(6) = 1/2 * 6 + 9
g(6) = 3 + 9
g(6) = 12

7. Carlos is renovating a house and hires a plumber to install the piping for 4 points
the new bathroom. The plumber charges an initial fee plus an hourly rate
for the number of hours it will take to complete the installation. The
function y = 100 + 35x can be used to model the total cost of the job, in
dollars. What does the slope in the expression of this function represent? *
the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x
Answer:
the cost per hour of installation work, $35
Step-by-step explanation:
y = 35x + 100
the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,
Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2
Answer: Plz mark me brainlest
Step-by-step explanation:
Just Simply Use Identity:
a^2 - b^2 = ( a+b) ( a-b)
Then:
( 49X^4 - 36 X^2) = 0
(7 X^2 + 6 X) ( 7X^2 - 6X) =0
7X^2 + 6X = 0, then X( 7X +6) =0 X=0, 7x +6 =0 X = -6/7
7X^2 -6x =0 X( 7x - 6) =0 X =0 7x -6 =0 X =6/7
Pull out a factor of x² from f(x) :
16x⁴ - 49x² = x² (16x² - 49)
Now write it as a difference of squares, then factorize:
16x⁴ - 49x² = x² ((4x)² - 7²)
16x⁴ - 49x² = x² (4x - 7) (4x + 7)
Set this equal to 0 and solve for x :
x² (4x - 7) (4x + 7) = 0
x² = 0 or 4x - 7 = 0 or 4x + 7 = 0
x = 0 or x = 7/4 or x = -7/4

Step-by-step explanation:
u should know this not that hard to do
help ill give hella points plz thx
Answer:
Using the variables it gives us it is B=150m
Step-by-step explanation:
1.) $1800-$1350=$450
$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months
2.) 450/3=150
You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150
So you put the numbers in B = Zachary's balance after m months and you get B=150m
Answer:
150m

6x-5 = -6(x+2)
I keep getting an incorrect fraction answer please help
Answer:
x = -7/12 or -0.583.. repeating.
Step-by-step explanation:
6x-5= -6(x+2)
___________ (distributive property)
(to group like terms)
6x-5 = -6x-12
___________ (addition poe) (add 6x on both sides to cancel -6 out)
+6x +6x
___________
12x-5 = -12
__________
+5 +5 (addition poe) (add 5 to both sides to cancel -5 out)
__________
12x = -7
__________
÷12 ÷12 (division poe) (divide both sides by 12 to get x)
x = -7/12

sin^2x + sin^2x + cos²x
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.

is Gobbledygook a word
Answer:
Lol that is a word.
DeShaun and Vu are brothers who like to make bets about the outcomes of different contests between them. Before the last bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7. Vu lost the latest competition, and now the ratio of the amount of Vu's money is 8:3. If Vu had $280 before the last competition, how much does Vu have now that he lost the bet?
Answer: Vu have $60.
Step-by-step explanation:
Given: Before bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7.
Let Deshaun's money =4x and Vu's money = 7x
If Vu had $280 before the last competition, then
7x = 280
⇒ x = 40 [Divide both sides by 7]
Deshaun's money = 4x = 4 x 40 = $160
After Vu lost bet, ratio becomes 8:3.
Let Deshaun's money = 8y and Vu's money = 3y
For Deshaun, 8x = 160 ⇒ y = 20 [divide both sides by 8]
Vu's money = 3 (20)=$60
Hence, Vu have $60.
