Step-by-step explanation:
- 2x + 4 + 3 = -4
-2x+7= -4
-2x= -4-7
-2x= -11
x=-11/-2
x=11/2
x=5.5 (if u want the answer in decimal form)
Y=mx+b is slope intercept form.
your answer would be y= -3/2+4
Answer:
6.53
Step-by-step explanation:
cos(theta)= adjacent/hypotenuse
cos(40)= 5/h
H= 5/cos(40)
=6.527
Rounded to the nearest hundredth will be 6.53
Answer:
a) (2x+7)(x-4)
b) x = -7/2 and x = 4
Step-by-step explanation:
a) (2x ?)(x ?)
set up the above and considered factors of 28 that, when paired with 2, would give me -1x and -28 → (1·28, 2·14, 4·7)
after trial-and-error, found that 4 and 7 worked (used un-FOIL)
b) 2x + 7 = 0
2x = -7
x = -7/2
*********
x-4 = 0
x = 4
