Answer:

<h2>c = 220</h2>

Step-by-step explanation:

f(x) = cx + d

<u>For the first equation</u>

f(50) = 27,000

Substitute the value of x that's 50 into the expression

That's

50c + d = 27,000

<u>For the second equation</u>

f(100) = 38,000

Substitute the value of x that's 100 into the expression

We have

100c + d = 38,000

Subtract the first equation from the second one to eliminate d

That's

100c - 50c + d - d = 38,000 - 27,000

50c = 11,000

Divide both sides by 50

We have the final answer as

<h3>c = 220</h3>

Hope this helps you

-5x - 7 < 28.....add 7 to both sides
-5x < 35....divide both sides by -5, change the inequality sign (u change the inequality sign when dividing/multiplying by a negative number)
x > -7

olga2289 [7]

Answer:

  • 3x² + 5x + 1 = 0 simplified
  • x = (-5 ± \sqrt{13})/6 roots

Step-by-step explanation:

<u>Given quadratic formula</u>

  • 3x² + 5x - 5 = - 6

<u>Standard form</u>

  • ax² + bx + c = 0

<u>Simplifying</u>

  • 3x² + 5x - 5 + 6 = 0
  • 3x² + 5x + 1 = 0

<u>Solving</u>

  • x = (-5 ± \sqrt{5^2 -4*3*1})/(2*3)
  • x = (-5 ± \sqrt{13})/6

Y=6x+5 is the equation. what is its gradient
Irina18 [472]
Gradient is synonymous to slope.

y = 6x + 5 is an example of a slope-intercept form of a straight-line equationl.

The slope-intercept equation is like this:

y = mx + b

where : m = slope ; b = "y-intercept"

y = 6x + 5

6 is the slope
5 is the y-intercept.

Since slope and gradient are synonymous, 6 is the gradient of the above equation.
