Answer:
4y= -x - 28
Step-by-step explanation:
the products of the gradient of parallel lines is 1
m1 x m2=1.......(1)
8-4x=0
re-arranging we have
0=-4x +8
comparing with y=mx +c we have
m1=-4
put the value of m1 in eqn 1
-4 xm2 =1
m2 =-1\2
from the relation.....
m=y-y1\x-x1
put the value of m1 above
-1\2=y-(-9)\x-0
cross multiply
-1(x-8)=4(y+9)
-x +8=4y+36
re-arranging we have
4y=-x-36+8
4y=-x-28//

She's rounding down. Thinking you use the number from the hundred place. You round using the tens place. It's over 50 so u go off the 75 in this case ending up with 1,300
Answer:
y=3x-27
Step-by-step explanation:
Answer:
Arjun is 20 years old and Shreya is 10 years old.
Step-by-step explanation:
5 YEARS AGO-
Arjun: 2x-5
Shreya: x-5
NOW-
Arjun: 2x
Shreya: x
EQUATION-
2x-5=3(x-5) = 2x-5=3x-15
(add 15 on both sides)
2x+10=3x
(subract 2x from both sides)
x=10
Therefore, Arjun is 20 years old and Shreya is 10 years old :)
Answer:
(x-1) (x+4)
Step-by-step explanation:
x^2 +3x-4
What 2 terms multiply to -4 and add to 3
-1*4 = -4
-1+4 = 3
(x-1) (x+4)
