Answer:
The second option
Step-by-step explanation:
Here, we need to multiply each part of the matrix by -10.
This will give us: [ -230 380 ]
[ -170 60 ]
So, the answer is the second option.
Answer:
X=75 y=90
Step-by-step explanation:
180-105=75
X=75
180-90=90
Y=90
Answer:
Add
Step-by-step explanation:
10.65*40=426
426+50=476
Let's solve your equation step-by-step.
6.75+38x=1314
Step 1: Simplify both sides of the equation.
38x+6.75=534
Step 2: Subtract 6.75 from both sides.
38x+6.75−6.75=534−6.75
38x=132
Step 3: Multiply both sides by 8/3.
(83)*(38x)=(83)*(132)
x=523
Answer:
x=1713
Step-by-step explanation:
We have to make x the subject:
y = x² + 4x + 4.
=> y = (x + 2)² by completing the square
=> x + 2 = ±√y
=> x = ±√y - 2
Therefore the inverse is y = ±√x - 2.
