Answer:

slope = 35/2

y intercept is 0

Step-by-step explanation:

the y-intercept is 0 because you can see from the graph that it intersect with y-axis at (0,0)

Slope = rise /run

pick a point (8, 140)

rise = 140

run = 8

slope = 140/8 = 70/4 = 35/2

Find the solution of this system of equations 5x - 6y =-90 -10x - 6y =-90

ExtremeBDS [4]

5x - 6y = -90

-10 x - 6y = -90

Subtracting,

15x = 0

x = 0

y = -90/(-6) = 15

Answer: x=0, y=15

Does anyone know the answer?

azamat

Answer:

1=163 degrees

2=×=10 degrees

3=×=3

Step-by-step explanation:

54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees

54x+9x+1-10=180

63x-9=180

63×=180+9

63×=189

63×÷63×=189÷63×

X=3

Angle in bold print is (54x+1)

54×3=162

162+1=163 degrees

No.2 Find x

7x+35+x+65 =180

7x+x+35×65=180

8x+100=180

8x=180-100

8x=80

8x÷8x=80÷8

X=10 degrees

No.3 Find x

54x+1+9x-10=180

54x+9x+1-10=180

63x-9=180

63x=180+9

63x=189

63x÷63x=189÷63

X=3

If f(y) = 2y - 2/5,<br> what is f(f^-1(1024))?

SCORPION-xisa [38]

Answer:

-0.399

Step-by-step explanation:

f^-1(1024)=(2*1024-2/5)^-1= 0.000488

f(0.000488)=2*0.000488-2/5= -0.399
