Answer:
A single cheeseburger order cost $1.23
A single fries order cost $1.28
Step-by-step explanation:
Let the cost of cheeseburgers be c and the cost of fries be f
Mathematically;
4c + 3f = 10.75 ••••(i)
Secondly;
5c + 2f = 11.2 ••••(ii)
We have two equations to solve simultaneously;
Multiply i by 2 and ii by 3
8c + 6f = 21.5
15c + 6f = 33.6
Subtract ii from i
-7c = -12.1
c = 1.73
Recall;
5c + 2f = 11.2
5(1.73) + 2f = 11.2
2f = 11.2-8.65
2f = 2.55
f = 2.55/2
f = 1.28
Answer: X = y - yi - 7i
Y = (x + 7i)/(1 - i)
Step-by-step explanation: for the case of (X) you only need to pass the 7i to the other side with the subtraction sign (-7i), then we get this equation:
x + 7i = y − yi
X = y - yi - 7i
in the case of the (Y), first we select the common multiple.
y - yi = y(1 - i)
if we replace it in the original expression, we get the following equation:
x + 7i = y(1 - i)
after that you can pass the value (1 - i) to the other side dividing,
Y = (x + 7i)/(1 - i)
Answer:
(-3/8/-(3/8) then you calculate -3/8*(-3/8) then its going to be - 3/-8*3/8 which equals -3/-3 and that becomes -(-3/3) then that becomes 3/3 and the ANSWER IS 1
Step-by-step explanation: Look at answer above.^^^
<u>Given</u>:
The parent function is
We need to determine the equation for the new function g(x)
<u>Vertical shift:</u>
From the graph, it is obvious that the parent function is shifted 6 units upwards.
The general rule to shift the graph c units upwards is
Thus, using the rule, the vertical shift of the new function g(x) is given by
<u>Horizontal shift:</u>
From the graph, it is obvious that the parent function is shifted 2 units to the right.
The general rule to shift the graph c units to the right is
Thus, the horizontal shift of the new function g(x) is given by
<u>Equation for the new function g(x):</u>
Since, the new function is shifted 2 units to the right and 6 units upward is given by the equation,
Hence, the equation of the new function is
