Answer:
-21 is the correct answer
Step-by-step explanation:
-7.5 - 5 - 8.5 = -21
Answer: 120 minutes.
not sure if im right lol brainliest or a thank u please :)) <3
4(u+3)+3u=-2
distribute: 4u+12+3u=-2
simplify: 7u+12=-2
isolate the variable: 7u=-14
divide: u=-2
check answer: 4(-2+3)+3(-2)=-2
-8+12-6=-2
-2=-2
therefore, u= -2
Answer: one solution x + 3 = 5 x = 2 no other other value for x is possible
No solution: (x + 3) = 2(x +3)
Infinitely many solutions: x+3 = 3 + x
Step-by-step explanation:
why (x + 3) = 2(x +3) has no solution. Can you solve?
x+3=2x+6 -x=3 x=-3 substute -3 for x
(-3)+ 3)= 2[(-3) +3]
-3+3 = -6 +3
0 = -3 False!
x+3 = 3 + x has infinitely many solutions. Substitute any number for x, and the equation is true (5)+3=3+(5) 8=8 . 11111+3 =3+11111 11114=11114
Slope-intercept form of a line:
y=mx+b
m=slope
We have this equation of a line:
y=2x+3
The slope of the line will be; m=2
Ohter line that is parallel to this line(y=2x+3) will have the same slope, therefore the slope will be: m=2
Point-slope form: we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀).
We have thel point (-4,1) and the slope:
therefore:
y-1=2(x+4) (point-slope form)
y-1=2x+8
y=2x+8+1
y=2x+9 (slope-intercept form).
answer: the equation of the line that is parallel to this line y=2x+3 , is:
y=2x+9
