Can someone do the whole thing

Mathematics
1 answer:
olga_2 [115]4 years ago
8 0

Answer:

1

Step-by-step explanation:

y=mx+b,  equation for slope-intercept line

we can work out the equation based on given two points (1,1) and (7,4)

  • m=(y2-y1)/(x2-x1)= (4-1)/(7-1)= 3/6= 1/2

y=1/2x+b

For (1,1)

  • 1= 1/2+b ⇒ b= 1/2

For (7,4)

  • 4=7*1/2+b ⇒ b= 1/2

So we get

  • y= 1/2x+1/2

The answer is 1 for question mark

\bf 15x^2-24x+9\div 3x-3\implies \cfrac{15x^2-24x+9}{3x-3}\implies \cfrac{\underline{3}(5x^2-8x+3)}{\underline{3}(x-1)}
\\\\\\
\cfrac{5x^2-8x+3}{x-1}\implies \cfrac{(5x-3)\underline{(x-1)}}{\underline{(x-1)}}\implies 5x-3

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>

What is -18x - x = 5x -6 PLEASE ANSWER CORRECTLY IT IS MY HOMEWORK
uysha [10]

Answer:

\large\boxed{x=\dfrac{1}{4}}

Step-by-step explanation:

-18x-x=5x-6\\\\-19x=5x-6\qquad\text{subtract}\ 5x\ \text{from both sides}\\\\-19x-5x=5x-5x-6\\\\-24x=-6\qquad\text{divide both sides by (-24)}\\\\\dfrac{-24x}{-24}=\dfrac{-6}{-24}\\\\x=\dfrac{6:6}{24:6}\\\\x=\dfrac{1}{4}

Solve 12(x - 2) + 3x = {(x + 12) + 10x
jeka94

Answer:

x=9

Let's solve your equation step-by-step

12(x−2)+3x=x+12+10x

<em>Step 1: Simplify both sides of the equation.</em>

12(x−2)+3x=x+12+10x

(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)

12x+−24+3x=x+12+10x

(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)

15x+−24=11x+12

15x−24=11x+12

<em>Step 2: Subtract 11x from both sides.</em>

15x−24−11x=11x+12−11x

4x−24=12

<em>Step 3: Add 24 to both sides.</em>

4x−24+24=12+24

4x=36

<em>Step 4: Divide both sides by 4.</em>

4x/4=36/4

x=9

Answer:

<u>x=9</u>
