Which system of equations has infinitely many solutions? On a coordinate plane, 2 lines are parallel to each other. On a coordinate plane, 2 lines intersect at (negative 1, 0). On a coordinate plane, a line has a negative slope.

Answer:

x = -3

y= 7

Step-by-step explanation:

x + 3y=18 ----(1)

-x - 4y=-25 -----(2)

from equation (1)

x = 18 - 3y ---(3)

putting equation (3) into equation (2)

-(18 - 3y) - 4y = -25

18 + 3y -4y = -25

3y - 4y = -25 - 18

-y = -7

y = 7 ✓

Putting y=7 into equation (1)

x + 3(7) = 18

x + 21 = 18

x = 18 - 21

x = -3 ✓

Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Answer:

10 19/10 meters

Step-by-step explanation:

Step one:

given data

let the amount of string used for the soccer field be x

and the amount used for coach spot be y

Also, let the total string used be represented as T

Step two:

Hence the expression for the total is

T= x+y

T= 9 1/2+ 2 2/5

T= 9.5+ 2.4

T= 11.9

or

T= 119/10 meters

or

T= 10 19/10 meters

Answer:

35

Step-by-step explanation:

Answer:

you should try adding then subtractung the total to the part

Answer:

(-3,-2)

Step-by-step explanation:

If you draw a line across from Point A to -3, and a line down from Point P to -2, you get the point (-3,-2) and a right triangle.

Answer:

-5x

Step-by-step explanation:

Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:

7(-1)+4=-3

-1-4=-5

5(-1)=-5

-5(-1)=5

And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).

-5x will be the largest among the options since x is the negative integer.

On the number line, a negative integer is an integer that is to the left of zero. It is not equal to zero.

Given, x is a negative integer, all given options will become negative except " -5x".  written with a minus sign. a number smaller than zero, but not a fraction or a decimal fraction.

Since for any value of x, all the given options will be negative.

Therefore, Due to the fact that x is a negative integer, -5x will be the largest selection.
