Answer:

Line passing through (0,2),(1,-21).

Step-by-step explanation:

y=-23x+2\\at\ y\ axis\ x=0\\y=-23\times0+2\\y=2

hence this line passes through (0,2).

When x=1

y=-23\times1+2\\y=-21

Hence this line passes through (1,-21).

Algebra problem!!! Please help me!!!
zmey [24]

Good morning Brainiac

x+y = 13

1/2 x +y = 10


We gonna solve x+y=13 for x

So let's start by adding -y to both sides

x+y -y = 13-y

x= -y +13

Now substitute -y+13 for x in 1/2 x +y=10

1/2 x +y = 10

1/2 (-y+13)+y=10

1/2 y + 13/2 = 10

Now add -13/2 to both sides

1/2 y+13/2 -13/2 = 10- 13/2

1/2 y = 7/2

Now eliminate the common denominator which is 2

y = 7

Now we have the value for y, so lets find the value for x by substitute 7 for y in x= -y+13

x= -y+13

x= -7 + 13

x= 6

Answer : (6,7)

The answer is B


I hope that's help and if you have questions please let me know :)

Area can be described as a measuring unit to measure the space in any flat surface. The square is a flat surface comprising of four equal sides. Area of a square would be the measure of the length of each size.

As per the question, the area of lawn is 196 yards and it is square shaped. This means that the length of each side would be would be 14 yards.

The area will be calculated by taking the square root of one of the equal sides. The square root of 14 is 196. hence, the correct answer is 14 yards.
