Answer:
-127
Step-by-step explanation:
first multiplied the ones in parentheses
12+5-144
then you add
12+5=17
17-144=-127
Answer:
p > 7
Step-by-step explanation:
Distribute the parenthesis on the left side
4p - 16 > 12 ( add 16 to both sides )
4p > 28 ( divide both sides by 4 )
p > 7
Answer:
(5y-2)x(2x+5)
Step by step explanation:
10xy-4x+25y-10
Factor out 2x from the expression
2x*(5y-2)+25y-10
Factor our 5 from the expression
2x*(5y-2)+5(5y-2)
Factor out 5y-2 from the expression
(5y-2)x(2x+5)
It is 21. Seven 1/7th's makes 7/7 which equals one. So multiply 7x3 and that is 21.
Answer: Y = -2x + 10
Step-by-step explanation:
You can find the slope by using the slope formula
which is y2 - y1 over x2 - y1
4 - 2 = 2
3 - 4 = -1 so the slope is -2/1 or just -2x
Now to find b we plug in any 2 points
0 = -2(5) + b
0 = -10 + b
add 10 to both sides so -10 cancels out
10 = b
or
b = 10 (same thing)
so the equation would be
y = -2x + 10
