Answer:
1) one solution
2) Infinitely many solution
3) no solution
Step-by-step explanation:
The first equation is -14-8x=-2(-3x+7)
Let us expand the right hand side to get:
-14-8x=-2*-3x+-2*7
We multiply -14-8x=6x-14
We group similar terms to get:
-8x-6x=-14+14
Combine similar terms to get:
-14x=0
Divide through by -14 to get:
x=0
2) The second equation is 3+5x=5(x+2)-7
We expand to obtain:
3+5x=5x+5*2-7
Multiply to get:
3+5x=5x+10-7
This gives us
3+5x=5x+3
5x=5x
1=1
There is infinitely many solutions
3) The third equation is: 36-7x=-7(x-5)
We expand to get:
36-7x=-7x+35
Group similar terms;
-7x+7x=35-36
0=-1
This statement is not true so there is no solution.
Answer:
2/7
Step-by-step explanation:
-1 1/7 + 6/7 = -8/7 + 6/7 = 2/7
The triangle of height 5 units and base 7 units will be as follows:
(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
Answer:
m = (2 - (-1)) / (0 - (-1)) = 3/1 = 3
y = 3 * (x - 0) + 2
y = 3 * x + 2
