We have that
<span>the point (7, 1)
case </span><span>A.) y = 5x + 4
if the point </span>(7, 1) lie to the line
so
for x=7 the value of y must be 1
y=5*7+4------> y=39
39 is not 1---------> the point does not belong to the line
case <span>B.) y = -x + 8
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-7+8------> y=1--------> the point belongs to the line
case <span>C.) y = x - 10
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=7-10------> y=-3
-3 is not 1---------> the point does not belong to the line
case <span>D.) y = -4x + 3
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-4*7+3------> y=-25
-25 is not 1---------> the point does not belong to the line
the answer is the option
B.) y = -x + 8
what is range of the inverse of the relation {(1, 7), (-2, 4), (5, 6), (2, 8)} A. {1, 2,5} B. {-4, 6, 7, 8} C. {1, 5} D. {-4, 7,

The answer should be the domain of this relation. {-2, 1, 2, 5} but I do not see that as one of your answer choices.
The inverse of a relation is when you switch the domain and range. In other words, the domain of the original relation becomes the range of the inverse.
X = -b/2a
x = -8/4
x = -2
Plug -2 in for x and solve for y
y = 2(-2)^2 + 8(-2) -3
y = 8 -16 -3
y = -11
Vertex (-2, -11)
Its b
and I dont rlly feel like explaining so yea
There are fifty two weeks in the year.
To find how much commission she earns in a year, multiply her weekly commission by the number of weeks per year.
274*52= 14248
To find how much money is taken from taxes, multiply the amount of money she is taxed weekly by the number of weeks in a year.
68*52= 3536
Now, simply add the amount of money she made in the year with her bonus (which I'm assuming is a one time bonus for being hired) and subtract the amount of money she is taxed.
14248+550-3536= 11262
Mrs. Sanchez earns $11262 a year.
