Part A is $650. Part B is 400+0.05s=1350, and part C is $19,000. For part A, it is $400+ 5% of total sales. So, it would be 400+5% times 5000 (which is the total sales of last week). Turn the 5% into a decimal so 400+0.05 times 5000. Then it would be 400+250, which is 650. For part B, it would be $400 per week and 5% of total sales for that week. This as an equation would be $400+0.05 times s=$1350. We can put 0.05 and the variable s together. So, it would then be 400+0.05s=$1350. This is the equation. For part C, we have to solve the equation in part B. $400+0.05s=$1350. Subtract 400 from 400 and 1350. This now makes the equation 0.05s= $950. Divide both sides by 0.05 and you get 19,000.
Answer:
4/2
Step-by-step explanation:
Answer:
11 and 7
Step-by-step explanation:
let x be the bigger number and y the smaller
the sum of the two numbers is 18
x+y=18
x=18-y------i
the sum of the greater number and twice the smaller number is 25
x+2y=25----ii
substituting i in ii
18-y+2y=25
collecting like terms
y=25-18
y=7
subtitute for y in i to get x
x=18-y
x=18-7
x=11
Answer:
Standard y=1
Slope Intercept y=2x-3
Step-by-step explanation:
-3y = -3
divide both sides by -3
y=1
8x-4y=12
move variable to the right -4y=12-8x
divide both sides by 4 y = -3+2x
The equation for
the standard form of parabola is given as:
y = A (x - h)^2 +
k
with (h, k) being
the (x, y) coordinates of the vertex
For the given
problem, we are given that (h, k) = (5, - 12).
We can then use point (0, 63) for x and y to solve for A
63 = A (0 - 5)^2 - 12
75 = A (25)
A = 75 / 25
A = 3
Equation of given
parabola:
y = 3 (x - 5)^2 - 12
We can now solve for the x –intercept:
Set y = 0, then solve for x
0 = 3 (x - 5)^2 -
12
3 (x - 5)^2 = 12
(x - 5)^2 = 4
Taking sqrt of
both sides
x - 5= ±2
x = -2 - 5 = -7
and x = 2 - 5 = - 3
x = -3, -7
Answer:
x-intercepts of given parabola: -3 and -7
(-3, 0) and (-7,
0)
