Step-by-step explanation:Step-by-step explanation:
For Sienna to be able to take the square root of both sides while solving a quadratic equation, she must have an expression with square on at least, the side that contains the variable she is trying to determine. Equation of the form:
(x + a) ² = b
'a' and 'b' could be any number, -1, 0, 1/3, -5/6, anything really.
So, she can take square roots of both sides then, like this
√(x + a)² = √b
x + a = ±√b
x = -a ± √b
Square roots always cancel out squares, and the '±' is because a square is satisfies by both + and -, 3² = 9, and (-3)² = 9.
It is the nature of the problem being solved that determines if we take just one or both of these answers.
Answer:
4/3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1
take the y from one of the points and subtract the y from the other point, the divide that by the x of the first y you picked and subtract the x of the second y
(-16)-(-8)/(-15)-(-9)
-8/-6
simplify
4/3
the slope is 4/3
Answer:
5 hours
Step-by-step explanation:
Each person works at a rate 1/100 of wall completed per hour.So five men working at the rate would be 5/100. So, it would...
Would appreciate your sharing actual inequalities to graph. Otherwise the topic is a bit broad.
Supposing you wanted to graph the inequality x<5:
Draw a dashed line through x=5, and then shade the area to the left of this line.
Supposing you wanted to graph the inequality x less than or equal to 5:
Draw a solid line through x=5, and then shade the area to the left of this line.
Please, respond with an inequality that you want to graph, and I'll help you with it.
The answer si that the first ten odd integers are all even. Maybe this is really a fact but not a conjecture
