Answer:
Equation pf parallel line y = 4x + C
now this line pass through (-2,4) so it satisfies the eqn
Then, 4 = -8+C
C = 12
<h2>Hence required equation:- </h2>
<h2>y = 4x+12.....</h2>
hope it helps
Answer:
See below
Step-by-step explanation:
x^2-3x-40 Factor
(x - 8) (x + 5)
The x intercepts are -5 and 8
(negative infinity, -5)
(8, positive infinity)
Answer:
The answer is 21/22
Step-by-step explanation:
n/7=3/22
then you cross-multiply
we have 22n=21
divide both sides by 22 to make n the subject of formula
n=21/22
this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m
In order to get an 81 average,
the student has to get 81x5=405
71+96+90+73+?=405
330+?=405
405-330=75
he needs to get an 75
