Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?

Rainbow [258]

Answer:

$m(x, y)=(\frac{7}{2} , -\frac{5}{2} )$

Step-by-step explanation:

Midpoint of line segment is calculated as

$m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )$ -----------(1)

Here

$(x_1, y_1) = (12,2) \ \ and \ \ (x_2, y_2) = (-5, -7)$

Substituting values in equation (1)

$m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )$

$m(x, y)=(\frac{7}{2} , -\frac{5}{2} )$

Javier rode his bike for a total of 40 minutes. The number of minutes he rode after lunch is 4 times the number of minutes he ro

Greeley [361]

Javier rode his bike for a total of 40 minutes.

Let x be the minutes Javier ride after lunch

Let y be the minutes Javier ride before lunch

The number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch

x = 4 y

The number of minutes he rode after lunch + number of minutes he rode before lunch = 40

x + y = 40

We know x= 4y

4y + y = 40

5y = 40

y = 8

x= 4y so x= 4(8) = 32

Javier ride 32 minutes after lunch

[scale factor ]=[ABC]/[DEF]---------> 8/4--------> 2

the answer is
the scale factor for a dilation image of DEF to obtain ABC is 2

-4( x – 4) = 8 – 4x last one NEED help

Ilya [14]

16=8

first you need to get rid of the parenthesis by doing distributive property which gives you -4x+16=8-4x next you cancel equal terms which is -4x so then you get

16=8 btw the equation would be false

Murrr4er [49]

Answer:

72 campers participated this year

Step-by-step explanation:

Percentages

To determine x% of y, we must calculate x*y/100.

The number of campers that participated in Big Lake Camp during its first year was 40. We now want to know the number of campers that participated this year, if the attendance was 180% of the first year's.

The new attendance is calculated as follows:

40 * 180 / 100 = 72

72 campers participated this year
