Answer:

X=3,1/4

Step-by-step explanation:

4x²-(12+1)x+3=0

or,4x²-12x-x+3=0

or,4x(x-3)-1(x-3)=0

or,(4x-1)(x-3)=0

Either,4x-1=0➡️ 4x=1

X=1/4

OR,x-3=0➡️ X=3

What is the distance between the points (-4,2) and (3,-5)

34kurt

Answer:

7√2 units

Step-by-step explanation:

The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

Here, x1=-4 and y1=2

x2=3 and y2=-5

$\sqrt{ {(3 - ( - 4))}^{2} + {( - 5 - 2)}^{2} }$

$\sqrt{ {(3 + 4)}^{2} + {( - 7)}^{2} }$

$\sqrt{ {(7)}^{2} + {( - 7)}^{2} }$

$\sqrt{49 + 49} = 7 \sqrt{2}$

The fraction models below represent two fractions of the same whole. How much of the Fraction 5 over 8 is in the Fraction 1 over

IrinaVladis [17]

To find how much of 5/8 is you would need to divide 1/2 by 5/8:

X = (1/2) / (5/8)

When dividing fractions, you reverse the second fraction and multiply:

X = (1/2) x (8/5)

X = 8/10

Simplify:

X = 4/5

What is the slope of (-12,-12) and (9,-9)

telo118 [61]

Step-by-step explanation:

Slope, which is the same as gradient, is equal to

change in y axis ÷change in x axis

<h3> $slope = \frac{change \: in \: y}{change \: in \: x}$ </h3>

Our coordinates are (-12,-12) and (9,-9)

In (-12,-12),let the first -12 be x1 and the second one be y1

Same goes for the (9,-9), let 9 be X2 and -9l be y2

 $slope = \frac{y2 - y1}{x2 - x1}$ 

 $= - \frac{ - 9 - - 12}{9 - 12}$ 

 $= \frac{3}{21}$ 

=0.1428571429

= 0.1429
