5x = 15
x = 3
3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5
(3, -5)
Step-by-step explanation:
(8x8) + (16x16) = 64+256 = 320
√320 = 17.9
Answer:
y = - 2x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 9 ← is in slope- intercept form
with m =
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 2
y = - 2x + c ← is the partial equation
to find c substitute (3, 2 ) into the partial equation
2 = - 6 + c ⇒ c = 2 + 6 = 8
y = - 2x + 8 ← equation of perpendicular line
The correct answer is option B which is the value of Y will be 12.
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
If the ordered pair (-5/2, y) lies on the graph of y=7-2x,
The value of Y will be calculated as:-
Y = 7 - 2x
Y = 7 - 2 ( -5/2 )
Y = 7 - ( - 5 )
Y = 7 + 5
Y = 12
Therefore the correct answer is option B which is the value of Y will be 12.

Answer:
210
Step-by-step explanation:
1.(Subtract both sides) we know that 14 - 14 = 0 But now you turn ZERO Into an X because anytime you subtract and get a ZERO IT WOULD BE X SO NOW YOU WILL TRY TO FIND/SOLVE X' I HOPE THIS HELPED/HELPS! (: I GOT 15 AS THE ANSWER BY SUBTRACTING 224-14 AND THEN I GOT 210 AND DIVIDED BY 14. BUT SINCE THERE IS NO X=15 ,It would be 210 because of subtraction.
