Well you can substitute-2 to x and -6 to x and it it works then yes
But in this problem it's no because
-6<7(-2)+8
-6<-14+8
-6<-6
So -6 is not smaller than -6

Y = (p+ 2)x-3<br>is parallel to 5x + y<br>to 5x + y = 13. Find the value of p.​
satela [25.4K]

Answer:

y=−5x+5

Step-by-step explanation:

5x+y-13=0,(5,-20)

Rewrite in slope-intercept form.

y = − 5 x + 13

Using the slope-intercept form, the slope is − 5 . m = − 5

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope − 5 and a given point ( 5 , − 20 ) to substitute for x 1 and y 1 in the point-slope form y − y 1 = m ( x − x 1 ) , which is derived from the slope equation m = y 2 − y 1 x 2 − x 1 . y − ( − 20 ) = ( − 5 ) ( x − ( 5 ) )

Simplify the equation and keep it in point-slope form.

y + 20 = − 5 ⋅ ( x − 5 ) Solve for y .

 y=−5x+5

How many digits in hex do you need to represent integers up to 1, 000?
shepuryov [24]
You can convert 1000 to hex and see how many digits that requires:

1000_{10}=(3\cdot16^2+14\cdot16+8)_{10}=3\mathrm e8_{16}

So every integer below 1000 needs up to 3 digits.

Alternatively, we know that 16^2=256, and that 16^n requires n+1 digits in its hex representation (e.g. 16_{10}=10_{16}). Taking the logarithm, we get \log_{16}16^2=2, and adding 1 gives the number of digits needed to represent 16^2. Similarly,


\lfloor\log_{16}1000\rfloor+1=3

Ken spent 1/5 of his allowance on a movie, 3/8 on snacks, and 2/7 on games. If his allowance was $20, how much did Ken have left
Lisa [10]
1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07

Answer: $6.07 is the amount ken has remaining

tatuchka [14]

Answer:

  • Second term
  • Common factor

Step-by-step explanation:

Compare ratios and rates by finding equivalent ratios and rates with a common <em><u>second term</u></em> . Make predictions by finding a <em><u>common factor </u></em>and multiplying by it.

To compare ratios and rates favorably we need to find a common second term also to make predictions as well we need to find a common factor
