Hey!

The sum of four times a number and -2

Let us take the number as ' x '

( 4x - 2 )

Six times a number and 3

( 6x + 3 )

The sum = ( 4x - 2 ) + ( 6x + 3 )

Hope helps!

a line passes through (9, –9) and (10, –5).write an equation for the line in point-slope form. rewrite the equation in standard
Cerrena [4.2K]
The equation of the line in point-slope form is given by:
 y-yo = m (x-xo)

 Where,
 (xo, yo): point that belongs to the line
 m: slope of the line
 The slope is given by:
 m = \frac{y2-y1}{x2-x1}
 Substituting values:
 m = \frac{-5-(-9)}{10-9}
 Rewriting:
 m = \frac{-5+9}{10-9}
 m = \frac{4}{1}
 m=4
 Now we choose an ordered pair:
 (xo, yo) = (10, -5)

 Substituting values we have:
 y-(-5)=4(x-10)
 y+5=4(x-10)
 We now rewrite the equation in its standard form:
 y = mx + b

 Where,
 b: cut with the y axis.
 We have then:
 y = 4x - 40 - 5

y = 4x - 45
 Answer:
 point-slope form:
 y+5=4(x-10)
 or
 y+9=4(x-9)
 standard form
 y = 4x- 45

Solve the equation to find the value of m and n.<br> 2m + 3n = -5<br> 5m + 3n = 1
Leokris [45]

Answer:

m = 2, n = - 3

Step-by-step explanation:

Given the 2 equations

2m + 3n = - 5 → (1)

5m + 3n = 1 → (2)

Subtract (2) from (1) term by term to eliminate n

2m - 5m = - 5 - 1

- 3m = - 6 ( divide both sides by - 3 )

m = 2

Substitute m = 2 into either of the 2 equations and solve for n

Substituting into (1)

2(2) + 3n = - 5

4 + 3n = - 5 ( subtract 4 from both sides )

3n = - 9 ( divide both sides by 3 )

n = - 3
