Y-6=4(x+5) what are the Y and X intercept
Misha Larkins [42]
Hello.

<span>Reorder the terms: -6 + y = 4(x + 5)

  Reorder the terms: -6 + y = 4(5 + x) -6 + y = (5 * 4 + x * 4) -6 + y = (20 + 4x)

  Solving -6 + y = 20 + 4x Solving for variable 'y'.

 Move all terms containing y to the left, all other terms to the right.

 Add '6' to each side of the equation. -6 + 6 + y = 20 + 6 + 4x

 Combine like terms: -6 + 6 = 0 0 + y = 20 + 6 + 4x y = 20 + 6 + 4x

 Combine like terms: 20 + 6 = 26 y = 26 + 4x

 Simplifying y = 26 + 4x


</span>x-intercept: <span><span>(−<span>132</span>,0)</span><span>(-<span>132</span>,0)</span></span>y-intercept: <span>(0,26<span>)

Uncle Malik so the shirt at the rate of 1200 Naira and made a profit of 25% what is the cost price​
uysha [10]

If he made 25 percent profit, the selling price (1200 naira) is 125 percent.

If 125% is equal to 1200 naira

100 percent (the original) will be 100 × 1200 divided by 125

Which is 120000 ÷ 125

Therefore, the cost price is 960 naira
