Answer:
-4 = y
Step-by-step explanation:
3(6+5y)=2(-5+4y)
18 + 15y = -10 + 8y
+10 +10
28 + 15y = 8y
- 15y -15y
28 = - 7y
28/-7 = -4
-7y/-7 = y
Answer:
"The Quadratic Equation, Formula, & Discriminant. If ax² + bx + c = 0 then x = . The first equation is called the general form of a quadratic equation. The second equation is called the Quadratic Formula because it states the solution -- provides a formula for computing the simplified answer(s) by using the values of the first equation."
ANSWER
A.
It satisfies the top equation but not the bottom equation.
EXPLANATION
The given equations are;
2x-3y=18
5x+3y=3
When we substitute x=6 and y=-2 into the top equation we get,
2(6)-3(-2)=18
12+6=18
18=18
This is true. Hence the point satisfy the top equation.
But when we substitute x=6 and y=-2 into the bottom equation we get,
5(6)+3(-2)=3
30-6=3
24=3
Hence the bottom equation is not satisfied.
The first choice is correct.
Answer:
he will dig for 15 hours
Step-by-step explanation:
if a miner digs —90 feets in 6 hours
then he will dig –225 feet in x hours
—225 feet x 6 hours /—90 feet = 15 hours
No
Because they all are different in taste and smell
