Answer:
-9t
Step-by-step explanation:
-3t -6t
using multiplication of signs
-×-=+
so add the numbers because they have the same
coefficient
-3-6= -9
so
-3t-6t=9t
Answer:
y = 4/3x-7/3
Step-by-step explanation:
Slope intercept form is y=Mx+b; m=slope & b= y intercept
y=-4/3x+b
Now substitute x & y with the point given
(-9)=-4/3(5)+b
-9= -20/3+b
+20/3 +20/3
-7/3=b
Now substitute this into the original equation
y = 4/3x-7/3
Answer:
The answer would be 54d + 9
Step-by-step explanation:
To use the distributive property, just multiply the 9 to each term.
9 * 6d = 54d
9 * 1 = 9
And now put those terms together.
54d + 9
Answer:
Step-by-step explanation:
we have
----> equation A
-----> equation B
----> equation C
adds equation A and equation C
-----> equation D
adds equation B and equation C
-----> equation E
we have the system
-----> equation D
-----> equation E
Multiply equation E by -1.5 both sides
-----> equation F
adds equation D and equation F
<em>Find the value of z</em>
substitute the value of y in equation E (or substitute in equation D)
<em>Find the value of x</em>
substitute the value of y and z in equation A (or equation B or C)
therefore
The solution of the system of equations is
