Let x=number of cds and y=number of dvds

Elis [28]

X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===

x = 30

Solve for x give answer as radicals (roots)

skelet666 [1.2K]

Answer:

x = 15

Step-by-step explanation:

Use pythagorean theorem: $a^{2} +b^{2} = c^{2}$

$8^{2} +x^{2} =17^{2} \\ 64 + x^{2} = 289 \\\\x^{2} = 289 - 64\\x^{2} = 225\\x = 15$

The line above goes through points (-4,0) and (0,1). what is the equation of the line?

mariarad [96]

Answer:

y = $\frac{1}{4}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 1)

m = $\frac{1-0}{0+4}$ = $\frac{1}{4}$

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

y = $\frac{1}{4}$ x + 1 ← equation of line
