Correct Solution: He read 1.5 pages per minute.

Error Analysis: You should’ve divided 3 by 2 not 300. There are 300 pages in the book total. This information is irrelevant to the question. Cole reads 3 pages in two minutes. So you divide 3 by to to find out how many pages he reads per minute. 3/2=1.5

A line passes through the point (6, 7) and has a slope of 4.

8_murik_8 [283]

Answer:

y = 4x - 17

Step-by-step explanation:

we can use the equation y = mx + b

where m is the slope.

now we want to find the value of b.

7 = 24 + b

b= -17

so the answer is

y = 4x -17

Pedro wants to walk from the historic village to the science center. Then he will walk from the science center to the museum. If

MrRissso [65]

Answer:

5 hours

Step-by-step explanation:

Speed = 2 7/ 10 miles per hour

From the chart attached :

Distance between historic village and science center : (-4 1/2, 5 1/4) to (-4 1/2, -1 3/4)

Taking the sum of the absolute value of the y coordinate :

|5 1/4| + |-1 3/4| = 5 + 1 + 1/4 + 3/4 = 7

From science center to museum :

(-4 1/2, - 1 3/4) to (2, - 1 3/4)

Taking the sum of the absolute value of the x coordinate :

|4 1/2| + |2| = 4 + 2 + 1/2 = 6 1/2

Total distance traveled = 7 + 61/2 = 13 1/2 miles

Time taken = Distance / speed

Time taken = 13 1/2 ÷ 2 7/10

Time taken = 27/2 * 10/27

Time taken = 10/2

Time taken = 5 hours

Ind the equation of the tangent line to 9x^2+16y^2=52 through (2, -1)

EastWind [94]

Here are the steps.

In order to get the answer, first we need to get the x and y value of the center of the circle by using the equation of a circle (x^2 + y^2 = r^2)

<span>The center is (-9, -4)</span>

Once you get the center point, find the equation of the line (in a form of a radius) from the center point to point (2, -1). Get the slope.

The slope from center to point (2, -1) is 11/3

Finally, get the negative reciprocal of the slope from the previous step and form the equation using slope-intercept form ( y=mx + b). Then, that's the equation of the tangent line.

The slope of the tangent line is -3/11
The equation is y = -3/11x - 5/11
