2,376/10 = 0,2376 2,376*.01= 2,376
Answer:
I think if you take the two of the equations and subtract them from eachother then youll get a number being x=(blank) then just subsitute it in for the third equation and see if it works. (sorry if this doesnt help)
Step-by-step explanation:
Answer: 32/6
I hope this answer helps!
The answer is N=M+5 since you’re looking for Nadines points which equals marks points plus 5
16x^2 − 8x + 1 = 0
<span>Part A:
</span>b^2 - 4ac for ax^2 + bx + c
16x^2 − 8x + 1 = 0
so in this case,
a = 16, b = -8, c = 1
b^2 - 4ac
=(-8)^2 - (4 * 16* 1)
= 64 - 64
= 0
because it's equal 0, answer is one solution
Part B:
<span>4x^2 − 8x − 45 = 0
</span><span>solve the equation by factoring </span>
= (2x - 9)(2x + 5)
set (2x - 9)(2x + 5) equal to 0 to solve for x
so
(2x - 9)(2x + 5) = 0
2x - 9 = 0
x = 9/2
x = 4.5
2x + 5 = 0
x = -5/2
x = -2.5
answer
x = -2.5 or x = 4.5
Hope it helps
