Answer:
2
Step-by-step explanation:
Calculate the distance d using the distance formula
d =
with (x₁, y₁ ) (3, 8) and (x₂, y₂ ) = (9, 10)
d =
=
=
=
= 2 ← exact distance
≈ 6.32 ( to 2 dec. places )
Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11
Answer:
x=-6
Y=4
Step-by-step explanation:
Hi!
9[6+6(8-4)]
First solve in the parentheses
9[6+6·4]
Now multiply in the brackets.
9[6+24]
Now add in the brackets
9·30
Multiply
270
The answer is 270
Hope this helps! :)
