1 answer:
3241004551 [841]3 years ago
7 0

Answer:

1(5/16)=1.3125

7(5/16)=7.3125

26(5/16)=26.3125

Step-by-step explanation:

Given that 5/16=0.3125, the mixed fraction 1(5/16)=1+(5/16)=1+0.3125=1.3125

Also, 7(5/16)=7+(5/16)=7+0.3125=7.3125

Furthermore,

26(5/16)=26+(5/16)=26+0.3125=26.3125

In the same vein, given that 4/15=0.266

1(4/15)=1+(4/15)=1+0.266=1.266

17(4/15)=17+(4/15)=17+0.266=17.266

23(4/15)=23+(4/15)=23+0.266=23.266

Với điều kiện nào của m thì phương trình ( 3m^2 - 4) x -1=m-x có nghiệm duy nhất?
Shtirlitz [24]
 <span>a, để pt có nghiệm thì denta ≥ 0 <=> (3-m)^2 - 4( 3-2m) ≥ 0 <=> m^2 +2m-3 ≥ 0 ( ^ là mũ) 
giải bpt mới tìm được đó ta đc : m ≤ -3 hoặc m ≥ 1 
b, * Xét m-1=0 <=> m=1 => thay m=1 vào pt thì pt có 1 nghiệm là 1/8 (1) 
* Xét m-1 ≠ 0 <=> m ≠ 1 
=> pt có nghiệm khi denta' ≥ <=> (m+3)^2 - (m-1)(-m+2) ≥0 <=> 2m^2 +3m+11 ≥ 0 (*) 
-> bpt (*) có denta < 0 nên nó luôn đúng với mọi m ≠1 -> denta của pt đã cho luôn > 0 với mọi m ≠ 1 (2) 
từ (1) (2) => với mọi m pt luôn có nghiệm </span>

Find the missing value so that the<br> two points have a slope of 1/2. <br> (7,2) and (3,y)
creativ13 [48]

Answer:y=0

Step-by-step explanation:

slope=(y2 - y1) ➗ (x2 - x1)

1/2=(y-2) ➗ (3-7)

1/2=(y-2) ➗ -4

Cross multiplying we get

-4=2(y-2)

-4=2y-4

Collect like terms

-4+4=2y

0=2y

y=0

ASAP WILL MARK BRAINLYEST <br><br>solve these four please!!
s2008m [1.1K]

I dont know if you wanted the steps but:

x^2-4x-6=0

plug it into the equation:

\frac{-(-4)\sqrt{(-4)^2-4(1)(-6)}}{2(1)}

[tex] \frac{4\sqrt{40}}{2} [/tex]

\frac{4+2\sqrt{10}}{2}    \frac{4-2\sqrt{10}}{2}

x=2+\sqrt{10}

x=2-\sqrt{10}

x^2-4/3x+1/3 x=1 , x= 1/3

2x^2-3x+1=0 x=1 , x=1/2

6x^2+12x=-5

add the 5 to both sides

6x²+12x+5=0 plug the problem into the equation

x=\frac{-12\sqrt{12^{2}-4(6)(5)}}{2(6)}

x=[\frac{-12\sqrt{144-120}}{12}

x=\frac{-12\sqrt{24}}{12}

x=\frac{-12+2\sqrt{6}}{12} x=\frac{-12-2\sqrt{6}}{12}

\frac{-6+2\sqrt{6}}{6} \frac{-6-2\sqrt{6}}{6}

Kellie randomly chooses a number from 1 to 10. What is the probability she
Arte-miy333 [17]
The probability is 2/10 because the only numbers less than 3 from 1-10 is 1 and 2. So it would be 2/10, 20%, or unlikely.
