ANSWER
10 weeks, $310
EXPLANATION
We have a system of linear equations as both equations need to be satisfied by the same ordered pair (x,y):
y = 25x + 60
y = 30x + 10
We can solve this by substitution. Since y is equal to 25x+60, we can substitute in 25x + 60 for y in the equation y=30x+10
y = 30x + 10
25x + 60 = 30x + 10
Subtract 25x from both sides
60 = 5x + 10
Subtract 10 from both sides and then divide both sides by 5
50 = 5x
x = 10
x represents time in weeks, so 10 weeks.
Find y, the amount of money, by substituting x=10 into either equation.
If we use y = 30x + 10, then
y = 30x + 10
y = 30(10) + 10
y = 300 + 10
y = 310
y = 310 implies $310 so the answer is 10 weeks, $310.
One solution which would be 1.5 or 3/2 same thing
Answer:
4
Step-by-step explanation:
We'll do two things here. First remember that when a number is raised to an exponent, and the result is raised to another exponent, you can simply multiply those exponents and apply them to the base. So we can multiply -1/2 and -2/3, giving us 1/3, which is what we'll raise 64 to.
The other thing to remember is that a fractional exponent is the same as a root of that base. So raising a number to the power of 1/3 just means we want the cube root of that number.
Applying those and we get:
Answer:
3, -1
6,-4
IDK about the third vertices, you didn't give the original coordinates!
Step-by-step explanation:
180 degree rotation= (x,y) to (-x,-y)
3,1 goes to -3,-1
6,4 goes to -6, -4
IDK about the third vertice, you didn't mention it.
Reflection over y-axis= (x,y) to (-x,y)
-3, -1 goes to 3, -1
-6,-4 goes to 6,-4
hope this helps!

Answer:
Total = $31.71
Step-by-step explanation:
Given data:
pounds of turkey = 2.15 at a rate of 7.89/ pound
pounds of lamb = 1.87 at a rate of 7.89/ pound
cost of each item as
cost(T) = 2.15 × 7.89
cost(T) = $16.96
And for lamb
cost(L) = 1.87 × 7.89
cost (L) = $14.75
Total cost will be the summation of both cost
Total = 16.96 + 14.75
Total = $31.71
