How many solutions are there to the system of equations? StartLayout enlarged left-brace 1st row 4 x minus 5 y = 5 2nd row negat
kkurt [141]

Answer:

Only one solution  x=\frac{5}{4},y=0

Step-by-step explanation:

4x-5y=5..............(1)\\0.08x+0.10y=0.10...........(2)

Multiply equation (2) by 50

4x-5y=5........(3)

Now from equation (1)+ equation(3)

8x=10\\x=\frac{10}{8}\\x=\frac{5}{4}

Put the value in equation (1)

5-5y=5\\5y=0\\y=0

hence only one solution exists\left(\frac{5}{4},0\right).

Can someone please help me with this thanks
xenn [34]

Answer:

24 (units)

Step-by-step explanation:

Because Quadrilateral EFGH is being dilated by a scale factor of 3/4, this means that each side of E'F'G'H' gets multiplied by 3/4. In this case, we are going to divide by 3/4 to return to the original figure (or multiply by 4/3 since that is the reciprocal)

This means that side HE is 18/(3/4) = 18(4/3) = 72/3 = 24 units

Rewrite the equation 2x + 4y + 2 = 3y + 5 in general form. 
Anika [276]

General form of any equation is of the form AX+BY+C=0

Here A,B,C are three real numbers

THe given equation is

2x +4y+2=3y+5

To make right side equal to 0 we subtract 3y and 5 both sides

2x+4y+2-3y-5=0

Simplifying like terms

2x+y-3=0

Option B is the right answer
