Two matrices are the same if the entries of the two matrices in the same row and column are the equal.
For this equation to hold, we need
5x - 8 = 2
5x = 10
x = 2
Answer:
1
Step-by-step explanation:
Y=mx+b
so find your slope
y2-y1/x2-x1 so 13-7/4-2
you get 6/2 or simplified 3
so now you have the equation y=3x+b
next you want to plug in a point to your equation so
7=3(2)+b
now solve using PEMDAS
7=6+b
then you want to isolate your variable
7 = 6 + b
-6 -6
1=b and thats your slope intercept
hope this helped :)
Answer:
x =-1 y=4
Step-by-step explanation:
-1 ×4 is -4. 2×4 is 8
8 +-4 =4
D
There are infinite amounts of solution
I learned this way back in 8th grade
To divide fractions, you flip the second one and multiply them so it would be:
(-3/8) / (7/12)
-3/8 * 12/7
-36/56
This can be simplified to :
-9/14
Because you divide both the numerator and denominator by 4.
Hope this helps :)
