Answer:
Substitution, but this system of equations has no solution.
Step-by-step explanation:
2x-4y=10
2y+6=x
----------------
2(2y+6)-4y=10
4y+12-4y=10
12=10
no solution.
Find the solution set of x: x^2-7x= - 10.
Answer:
(x − 2)(x −5)
Step-by-step explanation:
x² - 7x = - 10
x² - 7x + 10 = 0
Find two numbers that when added together make −7 , and when multiplied make - 10.
The numbers − 2 and −5 fit the criteria.
x2− 7x + 10 = (x − 2)(x −5)
Step-by-step explanation:
I think that are
a)0.16
b)0.25
c)0.18
Answer:
$2.67
Step-by-step explanation:
$12.00 divided by 4.5 (aka four and a half) = 2.6666 = amount per pound
Round to the nearest cent. 2.666, that last six makes the six in the hundredths place round up to 7.
Answer:
any number that satisfies this equation is imaginary.
Step-by-step explanation:
if you take the square root of both sides to find x, you will get a negative 1 in the house. You can't have a negative number in the house, therefore, any number that satisfies this equation is imaginary.
