Answer:
y= -2x-22.
Step-by-step explanation:
1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;
2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);
3) the required equation in slope-interception form is:
y+16= -2x-6; ⇒ y= -2x-22.
note, the provided solution is not the only and shortest way.
Answer:
£148.8
Step-by-step explanation:
The necklace is £186 after the price was increased by 20%
20% of £186 is £37.2. We know this because 20% goes into 100% 5 times, so if we divide £186 by 5, we will find out what the 20% is £186 ÷ 5 = £37.2
£186 - 20% = <em>p</em>
£186 - £37.2 = <em>p</em>
£148.8 = <em>p</em>
<em />
The price of the necklace before the increase is £148.8
I hope that this helps :)
Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *
= 67
0.3 *
= 30
Divide as usual.
67 / 30 = 2
So, the answer is 2 1/3.
Answer:
Peter can make 10 tacos.
Step-by-step explanation:
Jaqueline's recipe calls for .1 pounds of beef per taco.
Given only 1 pound, multiply by, taking the reciprocal of .1 gives us 10 tacos.
