Subsitution method.
<span>
Y=3x - 11
</span><span>Y= -3x - 2
</span>
-3x - 2 = 3x - 11
+3x +3x
-2 = 6x - 11
+11 +11
6x = 9
x = 1.5
<span>Y=3(1.5) - 11
</span>y = 4.5 - 11
y = -6.5
Now we have our points.
Answer: x = 1.5 and y = -6.5
Answer:
constant: 4
coefficient:-5
variable:x
Step-by-step explanation:
You can easily search up the definition of each word and figure it out just saying. It's fine if u wanna do this-
Step-by-step explanation:
Length of base = 20cm
We will take the base as "b"
Area of a triangle = 1/2 x base x height
So the total area = 360 square feet
360 square feet = 1/2 x b x 36
360 = 36b /2
360 = 18b
b = 360/18
b = 20
So, Length of base = 20 cm
Let's check:
1/2 x 20 x 36 = 360
Which is the correct area!
Hope this helps!
Answer:
π/36 sec-1
Step-by-step explanation:
From the question we are given the formula below
s = rwt ..........eqn(1)
Where s= π/3m, r=3 m, t= 4 sec
We were not given value of " w" which implies we are required to find out values of" w"
We can make " w " the subject of the formula from eqn(1)
s = rwt
w= s/(rt)........eqn(2)
Then substitute for the values in eqn(2)
w= (π/3m ) / ( 3m × 4 sec)
= π/36 sec-1
Hence, the value of the
missing variable is π/36 sec-1
