Answer:
it would be Y= -2x+4
Step-by-step explanation:
To begin, we know that the b value is 4, because that is the x-intercept that is information given, so we can atomatically put that in.
Next we need to find the m value, which can be found by knowing the rules of a perpendicular eqution. to change it you must change the 1/2 and flip the equation and change the signs
soooooo 1/2 would change into 2/1 which is 2 and we would addd the negative sign so
Y=-2x+4
The answer is 14 because a negative number multiplied by another negative number is positive. So (-7)*(-2) is 14.
The value of x in the equation is 26.7
<h3>How to solve an equation?</h3>
0.75x + 1.5y = 40
−1.5x − 1.5y = −60
add both equation to eliminate y .
Therefore,
−1.5x + 0.75x = -0.75x
1.5y + (- 1.5y) = 0
40 + (-60) = -20
Hence,
-0.75x = - 20
divide both sides by -0.75
-0.75x / -0/75 = - 20 / -0.75
x = - 20 / -0.75
x = 26.6666666667
x = 26.7
