Step-by-step explanation:

$Total\ required\ food\ for\ sparky=4\frac{1}{4}\ cups\\\\Total\ required\ food\ for\ sparky=\frac{17}{4}\ cups\\\\Megan\ needs\ to\ feed\ him\ only\ \frac{2}{3}\ as\ much\\\\Food\ given\ by\ Megan=\frac{2}{3}\times Total\ required\ food\ for\ sparky\\\\Food\ given\ by\ Megan=\frac{2}{3}\times \frac{17}{4}\\\\Food\ given\ by\ Megan=\frac{17}{6}\ cups$

ONLY NEED TO DO 6, 8, 10, 12, 14.

zimovet [89]

Answer:

6 = (2,2)
8 = (0, -6)
10 =(13,-6)

Step-by-step explanation:

$Midpoint = (\frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} )\\$

$(5.8) =(x_1,y_1)\\(-1,-4) =(x_2,y_2)\\\\Midpoint =\left(\frac{-1+5}{2},\:\frac{-4+8}{2}\right)\\\\Midpoint =( \frac{4}{2} , \frac{4}{2} )\\\\Midpoint = ( 2 , 2)$

$(-3 ,-7) =(x_1 ,y_1)\\(3,-5)=(x_2,y_2)\\\\\left(\frac{3-3}{2},\:\frac{-5-7}{2}\right)\\ \\Midpoint = (\frac{0}{2} , \frac{-12}{2} )\\\\Midpoint = ( 0, -6)$

10.

$L(-9 ,4) =(x_1 ,y_1)\\K(2 , -1 ) = (x ,y )\\M(x_2 ,y_2 )=?\\ \\x = \frac{x_2+x_1}{2}\\ 2 = \frac{x_2 +(-9)}{2}\\ 2 = \frac{x_2-9}{2}\\ Cross\:Multiply\\\\4 =x_2-9\\4+9=x_2\\13 =x_2\\\\y = \frac{y_2+y_1}{2}\\ -1 = \frac{y_2 +4}{2} \\-1 \times 2= y_2+4\\-2 =y_2+4\\-2-4 =y_2\\-6 =y_2\\\\(x_2 ,y_2) = (13 , -6)\\$

I need help and only even numbers

Bess [88]

Answer:

12.

-1.9 , -1.8, -1.7

13.

Points in Quadrant IV have a positive x, and a negative y.

14.

The point (2,9) is reflected over the y-axis, which means the number in x has it's sign flipped.

(-2 , 9) is your answer

15.

In between -7 & -4 is <em>-6, -5</em>

b. -6 is your answer.

16.

Remember that Quadrant II has a negative x, and a positive y. This means that b. (-2, 5) is your answer.

17.

You are reflecting over the y-axis, so you are changing the sign of the x value.

(-3, 5) reflected over the y-axis is a. (3 , 5)

Solve using substitution

mestny [16]

Answer:

x=7, y=9. (7, 9).

Step-by-step explanation:

-3x+y=-12

5x-2y=17

---------------

y=-12-(-3x)

y=-12+3x

y=3x-12

5x-2(3x-12)=17

5x-6x+24=17

-x+24=17

-x=17-24

-x=-7

x=7

y=3(7)-12

y=21-12

y=9
