If the product of two number is 10 and the sum is 7 ,then the longest of the two number is​
irinina [24]

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

So

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

10/y+y= 7\\\\10/y= 7-y

cross multiply we have

10=y(7-y)\\\\10=7y-y^2

rearrange

y^2-7y+10=0

the factors of the quadratic expression are

-5 and -2

y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\

The longest side is 5 units

Explanation on How to answer what is the density of an object that has a mass of 73,430 and the volume of 7 m3
scZoUnD [109]

Answer:

Density = 10,490 g/m³

Step-by-step explanation:

Density = mass ÷ volume

here mass = 73,430 g

        volume = 7 m³

density = 73,430 ÷ 7

             = 10490 g/m³

Density = 10,490 g/m³

Find the slope of the line that passes through (10, 3) and (7, 11).
Vadim26 [7]

Answer:

Slope of the line is -\frac{8}{3}.

Step-by-step explanation:

Given points are:

(10, 3) and (7, 11)

Here,

x1 = 10 and y1 = 3

x2 = 7 and y2 = 11

Slope of a line is given by

m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{11-3}{7-10}\\\\m = \frac{8}{-3}

Therefore,

Slope of the line is -\frac{8}{3}.

Write y-5=6(x+1) in standard form and show work plz. Thanks
Nezavi [6.7K]

Answer:

x = (1/6y)+(-11/6)

Step-by-step explanation:

Step 1: Flip the equation.

6x+6=y−5

Step 2: Add -6 to both sides.

6x+6+−6=y−5+−6

6x=y−11

Step 3: Divide both sides by 6.

6x /6 = y−11 /6

x= (1 /6 y)+ (−11 /6)

Answer:

x = (1/6y)+(-11/6)
