The equation of required line is:

y=4x-7

Step-by-step explanation:

Slope-intercept form of equation of line is:

$y=mx+b$

Given

m=4

And

Point = (2,1)

Putting the value of slope, we get

$y=4x+b$

Putting the point in the equation

$1=4(2)+b\\1=8+b\\b=1-8\\b=-7$

Putting the values of b and m we get

$y=4x-7$

Hence,

The equation of required line is:

y=4x-7

Keywords: Slope-intercept form, equation of line

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estim

STALIN [3.7K]

Answer:

The inequality is $5.5n \leq 45$

Step-by-step explanation:

Total time:

The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.

In this question:

Same number(n) of both.

Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

$T = 2n + 3.5n = 5.5n$

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?

This means that:

$T \leq 45$

$5.5n \leq 45$

The inequality is $5.5n \leq 45$

Aleks04 [339]

So if 32 oz is 20% more than the average bottle, you multiply 32 by .20 which gives you 6.4. This means that the 32 oz bottle is 6.4 oz more than the regular bottle. Furthermore, 32 - 6.4 = 25.6 so that's how big the typical bottle is.
