Answer:

Step-by-step explanation:

A) 5x - 7 = 5x becomes -7 = 0 if 5x is subtracted from both sides. This result is never true, so NO SOLUTION

B)3x−9=3(x−3) Performing the indicated multiplication, we get

3x - 9 = 3x - 9. This is always true, so there are INFINITELY MANY SOLUTIONS

C)2x−6=−2(x−3) Performing the indicated multiplication, we get

2x - 6 = -2x + 6. Adding 2x - 6 to both sides results in

4x - 12 = 0, or 4x = 12. Thus, the solution is x = 3. ONE SOLUTION

D)2x+6−5x=−3(x This equation is incomplete

Solve (x+y) if x=-1/2 and y=-3

bixtya [17]

Answer:

$-3\frac{1}{2}$

Step-by-step explanation:

Solve

$(x+y)$

For x=-1/2 and y=-3

substitute the value of x and the value of y in the expression above

$x+y=(-\frac{1}{2})+(-3)$

Remember that

$(+1)(-1)=-1$

$x+y=-\frac{1}{2}-3=\frac{-1-6}{2}=-\frac{7}{2}$

Convert to mixed number

$-\frac{7}{2}=-\frac{6}{2}-\frac{1}{2}=-3\frac{1}{2}$

Can someone explain how to do it aswell please and thank you

Paul [167]

Answer:

B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*

Find the distance from the point (4,2) to the point (0,1).

vagabundo [1.1K]

Answer:

4.123 units

Step-by-step explanation:

Data provided:

Coordinates of point 1 as ( 4 , 2)

and,

Coordinates of point 2 as ( 0 , 1 )

Now,

The distance between the two point whose coordinates are given is calculated using the formula as:

distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

on substituting the values, we get

distance = $\sqrt{(0-4)^2+(1-2)^2}$

distance = $\sqrt{(-4)^2+(-1)^2}$

distance = $\sqrt{16+1}$

Distance = √17 = 4.123 units
