LenKa [72]3 years ago
6 0

Answer:

<h2>X=1.33</h2>

solution,

\frac{25}{6}  - 4x =  \frac{ - 9x + 5}{6}  \\  \: or \:  \frac{25 - 4x \times 6}{6}   =  \frac{ - 9x + 5}{6}  \\ or \:  \frac{25 - 24x}{6}  =  \frac{ - 9x + 5}{6}  \\ or \: 6(25 - 24x) = 6( - 9x + 5) \\ or \: 150 - 144x =  - 54x + 30 \\ or \:  - 144x + 54x = 30 - 150 \\ or \:  - 90x =  - 120 \\ or \: x =  \frac{ - 120}{ - 90}  \\or \:  x =  \frac{4}{3}  \\ x = 1.33

Hope this helps.

Good luck on your assignment.m

The rate of change for the interval between 2 and 6 on the x-axis is 3.

Given

On a coordinate plane, a parabola opens up.

Solid circles appear on the parabola at (negative 4, 14), (negative 3, 9. 5), (negative 2, 6), (0, 2), (1, 1. 5), (2, 2), (4, 6), (5, 9. 5), (6, 14).

<h3>What is the rate of change?</h3>

A rate of change defines how one quantity changes in relation to another quantity.

The rate of change for the interval between 2 and 6 on the x-axis is;

\rm Rate \ of \ change =\dfrac{2-14}{2-6}\\\\Rate \ of \ change =\dfrac{-12}{-4}\\\\Rate \ of \ change =3

Hence, the rate of change for the interval between 2 and 6 on the x-axis is 3.

X + 4y = 16<br> -X + 3y = -2 ​
jeyben [28]

Answer:

(8, 2 )

Step-by-step explanation:

Given the 2 equations

x + 4y = 16 → (1)

- x + 3y = - 2 → (2)

Adding the 2 equations term by term will eliminate the x- term

0 + 7y = 14

7y = 14 ( divide both sides by 7 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (1)

x + 4(2) = 16

x + 8 = 16 ( subtract 8 from both sides )

x = 8

solution is (8, 2 )

Line j has an equation of y - 8 = -2/3(x+5). Line K is perpendicular to line j and passes + through (-6, -2). What is the equati
riadik2000 [5.3K]

Answer:

y = \frac{3}{2} x + 7

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y - 8 = - \frac{2}{3} (x + 5) ← is in point- slope form

with m = - \frac{2}{3}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{3} } = \frac{3}{2}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept ) , then

y = \frac{3}{2} x + c ← is the partial equation

to find c substitute (- 6, - 2 ) into the partial equation

- 2 = - 9 + c ⇒ c = - 2 + 9 = 7

y = \frac{3}{2} x + 7 ← equation of line K
