Answer:
y = 2/5x - 2
Step-by-step explanation:
Step 1: Write equation
2x - 5y = 10
Step 2: Solve for <em>y</em>
- Subtract 2x on both sides: -5y = 10 - 2x
- Divide both sides by -5: y = -2 + 2/5x
- Rewrite: y = 2/5x - 2
Answer:
the k value is 6
Step-by-step explanation:
The form of a qruadratic equation is f(x)=a(x-h)^2 + k, so by comparing this to the function f(x)=-18(x-2)^2 + 6 we can see that K = 6, a = -18,and h = 2.
<h2>1000 rotations cover 1.76 km
</h2><h2>So, 1 revolution covers 1760/1000 m = 1.76 m </h2><h2>So, circumference = 1.76 m
</h2><h2>Radius = Circumference/2π = 1.76/2(22/7) = 1.76*7/44 = 0.28m</h2>
You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage. The example below shows this.
<span>What is 35% of $40?<span>Step 1<span>What is 10% of $40?10% of $40 = $40 ÷ 10 =<span> $4</span></span><span>10% is a relatively easy percentage and can be found by<span> dividing by 10</span>.</span></span><span>Step 2<span>3 x $4 = $1230% of $40 = $12</span>30% is 3 times ( 3 x) 10% so we multiply what 10% of $40 is by 3</span><span>Step 3<span>What is 5% of $40?5% of $40 = $4 ÷ 2 =<span> $2</span></span><span>5% is half of what 10% is so divide what 10% is by 2 .</span></span><span>Step 4<span>What is 35% of $40?$12 + $2 = $14</span><span>Add what</span></span></span>
