Answer:
A. x = -2
Step-by-step explanation:
2x² + 7x + 6 = 0
2(-2)² + 7(-2) + 6 = ?
8 + -14 + 6 = 0
Answer:
k= -89
Step-by-step explanation:
k = 10t - 19 and t = -7
k=10 (-7) - 19
k= -70 - 19
k= -89
Answer:
18:24 or simplest form is 3:4
Step-by-step explanation: If you don't need to simplify then it is 18:24, but if you simplify it by dividing 18 and 24 by 6, then the answer is 3:4 :)
Answer:
y=-1/4x+8
Step-by-step explanation:
To find the equation of a line that is perpendicular to a line, you would take the opposite reciprocal of the slope.
Before that, we need to change the equation into slope-intercept form.
-4x+y=10
y=4x+10
The opposite reciprocal of the slope is -1/4.
Now, let's use the point-slope formula to find our equation of the line that passes through (-4,9).
y-y1=m(x-x1)
y-9=-1/4(x-(-4))
y-9=-1/4x-1
y=-1/4x+8
The truck was going 40 miles per hour
The amount of time was 2 hours:
(90-80: 10)(10/2=5)
80 divided by two is 40
The car was going 45 miles per hour
(90-80:10)(10/2=5)
90 divided by two is 45
