Answer:

Step-by-step explanation:

Take any two points on the line

(-4,0) and (0,-1) find the slope

slope= y2-y1/x2-x1

$=\frac{-1-0}{0-(-4)}=\frac{-1}{0+4}=\frac{-1}{4}$

y-y1 = m(x-x1)

$y-0=\frac{-1}{4}[x-(-4)]\\\\y=\frac{-1}{4}(x+4)\\\\y=\frac{-1}{4}*x+4*\frac{-1}{4}\\\\y=\frac{-1}{4}x-1$

Masja [62]

Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7 Eqn 1

28x+15y=131 Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105 Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

$\frac{13x}{13}=\frac{26}{13}\\x=2$

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

$(5x)+(23+90-18)=180$
$5x+95=180$

Step 2: Subtract 95 from both sides.

$5x+95-95=180-95$
$5x=85$

Step 3: Divide both sides by 5.

$5x/5=85/5$
$x=17$

Step 4: Check if solution is correct.

$(5*17-18)+23+90=180$
$67+23+90=180$
$180=180$

Thus, x = 17.
