Answer:
so let's call the unknown number x.
-5/4 x X = 7/2
by changing the subject, X = 7/2 / -5/4
to divide fractions, we turn the fraction we're dividing by upside down and change the sign to multiplication. so X = 7/2 x 4/-5
after multiplying, X =>28/-10
simplified, X = 14/-5
Answer:
D) g(x) = (6/(x + 4)) + 4
Step-by-step explanation:
f(x) = 1/x
stretch by 6 times
g(x) = 6/x
shift 4 units left
g(x) = 6/(x + 4)
shift 4 units up
g(x) = 4 + 6/(x + 4)
Answer:
15
Step-by-step explanation:
we have to divide a value of y by a value of x
(15: 1) = 15
we can check this result by do other tries.
(30:2) = 15
(45:3) = 15
(60:4) = 15
Answer:
26 and 27
Step-by-step explanation:
Let the numbers be x and y
x + y = 53
xy = 702
x = 702/y
702/y + y = 53
Multiply through by y
702 + y^2 = 53y
y^2 - 53y + 702 = 0
y^2 - 27y - 26y + 702 = 0
y(y - 27) - 26(y - 27) = 0
(y - 27) (y - 26) = 0
y = 26 or 27
Solve for x in x + y = 53
if y = 26,
x = 53 - 26 = 27
if y = 27,
x = 53 - 27 = 26
The numbers are 26 and 27
The answer is C or D but I think its most definitely C
