Answer: $2800
Step-by-step explanation:
if the function is f(x) and shes already saved $1000 plug in the functions, or in other words plug in x for weeks.
1000 + 150 x
(plug in x)
1000 + 150 x 12
so now you do 150 x 12 which equels 1800
then add how muh shes saved and thats will be your total.
Answer: y=3 x=4
Step-by-step explanation:
Its a rectangle so the 2 horizontal sides are even and the vertical sides are even. So, since one side is 10, the other side has to be 10. So, 2y+4 = 10. subtract 4 from each side getting 2y = 6. divide by 2 to get the y by its self and you get y = 3.
For the horizontal side, 10 + 2x = 18. subtract 10 from each side. 2x = 8 divide by 2. x = 4
Answer:
It the 3rd one it's correct cuz i worked it out
Can i have a brainliest please!!:)
Step-by-step explanation:
solve your system by substitution.
c+3d=8;c=4d−6
Rewrite equations:
c=4d−6;c+3d=8
Step: Solve c=4d−6for c:
c=4d−6
Step: Substitute4d−6forcinc+3d=8:
c+3d=8
4d−6+3d=8
7d−6=8(Simplify both sides of the equation)
7d−6+6=8+6(Add 6 to both sides)
7d=14
7d
7
=
14
7
(Divide both sides by 7)
d=2
Step: Substitute2fordinc=4d−6:
c=4d−6
c=(4)(2)−6
c=2(Simplify both sides of the equation)
Answer:
c=2 and d=2
The answer is: [A]:
_________________________________________________
input: number of rowers number of rowers in the rowboat;
output: speed of the rowboat ;
_________________________________________________
NOTE: The input would be the independent variable and plotted on the "x-axis" of the graph; and the output would be the dependent variable and plotted on the "y-axis" of the graph.
________________________________________________
Let the variable of the equation be x.
Solution of the equation is given to us, hence,
x = -3 and x = 9
x + 3 = 0 and x - 9 = 0
Multiplying,
(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27
Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
