Answer:
x=20
Step-by-step explanation:
Answer:
OPTION C
Step-by-step explanation:
78-39=39
so: 39+39=78 (b=39)
so: 39+b= 78
S.S{-1 ,-2,-3,-4,-5,-6,-7,-8,-9}
Its only asking numbers less than zero but greater than-10 so 0 and -10 will not be included. Only numbers in bn
Replace the x in the expression by 0 and work it out:-
y-intercept = 2 (0)^2 - 7(0) + 9 = 9
Answer is option (4).
As it is right angled, thus it will be equal to 90.
= 2x + 5 + x + 25 = 90
= 3x + 30 = 90
= 3x = 60
= x = 60/3
= x = 20
