Answer:

Step-by-step explanation:

Let the each leg be x so,

√(x²+x²)=√98

or, √(2x²)=√98

or, x√2=7√2

or, x=7

For a diamond problem what two numbers' sums equal 31 and their product is 234?

s344n2d4d5 [400]

Let

x-------> the first number

y------> the second number

we know that

$x+y=31$

$x=31-y$

equation $1$

$x*y=234$

equation $2$

substitute equation 1 in equation 2

$(31-y)*y=234\\ 31y-y^{2} =234\\ -y^{2} +31y-234=0$

using a graph tool-----> to resolve the second order equation

see the attached figure

the solution is

$13 and 18$

(-4, -7) and (-6, 9) in slope-intercept form. Show work

BigorU [14]

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

$y = mx+b$

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

$m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8$

Putting slope in general equation

$y = -8x+b$

Putting (-6,9) in the equation

$9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39$

Putting the value of b we get

$y = -8x-39$

Hence,

Equation of line in slope-intercept form is: y = -8x-39
