Answer:
step 2
Step-by-step explanation:
The student first made an error in the step 2.
Because if we simplify the equation A in step 1, we should distribute the right side of the equation following the rule a(b-c) = a*b +a*(-c)
So, it would be
–7y = (-7)*(16)+(-7)*(-2z)
=> -7y = -112 + 14z
It’s number 2 the values it 24
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is inversely proportional to x² then the equation relating them is
y = 
← k is the constant of variation
To find k use any ordered pair from the table.
Using (1, 4 ) , then
4 = 
= 
( multiply both sides by 1
4 = k
y = 
← equation of variation
(b)
When y = 25 , then
25 = ( multiply both sides by x² )
25x² = 4 ( divide both sides by 25 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
Since x > 0 then x =
Answer:
5
Step-by-step explanation:
The function intersects the y-axis at 1, and its slope is 1, so the function of the graph is y = x+1. Plugin 4, and you get y = 5.
453.10/734 = .617% * 100 = 61.7% --> 62%
D. 62%
