Answer: C
Step-by-step explanation:
If a line is perpen to another line, then the other line has the opposite reciprocal of the slope.
y=-(1/4)x+2
slope of the other equation is +4
oly answer with positive slope is C
x' = 24/5
The rule for variable to variable' is multiply by 6/5, shown as y to y'
Answer: B) x + y = 17
1.60x + 2.45y = 34
Step-by-step explanation:
Cost of x = $1.60 per pound
Cost of y = $2.45 per pound
Total pounds of x and y = 17
Cost per pound of mixture = $2
Total number of pounds of the mixture :
x + y = 17
Since the cost per pound of the mixture = 2
Hence ;
(Cost of x * number of pounds of x) + (Cost of y * number of pounds of y)
(1.60 * x) + (2.45 * y) = (cost per pound of mixture * total number of pounds of the mixture)
1.60x + 2.45y = 2 * 17
1.60x + 2.45y = 34
All the primes of 24 is 1,2,3,4,6,8,12,and 24
So in your figure where as states that the figure has a triangle and AB = BC and DE = EF = DF, the ask is to find the measure of DFA if angle ABC is 30degree. <span>Base on my calculation and through step by step procedure and with the guidance of the theories and by the use of formulas, I came up with an answer of B. 35degree</span>
