Standard form: Ax + By = C where A, B, and C are integers.
(if you don't remember, integers are numbers like ...-2, -1, 0, 1, 2, 3...etc.)

Question 1
y+3=4(x-1)
Distribute the 4.
y+3=4x-4
Subtract 3 from the left.
y=4x-7
Subtract 4x from the right.
-4x+y=-7
multiply everything by -1 and make the x coefficient positive, it looks better
4x-y=7

y=1/4x-2
multiply everything by 4 to get rid of fractions
4y=x-8
subtract x
-x+4y=-8
multiply by -1
x-4y=8

y+2=2/3(x+4)
multiply by 3 to get rid of fractions
3y+6=2(x+4)
distribute
3y+6=2x+8
subtract 6
3y=2x+2
subtract 2x
-2x+3y=2
multiply by -1
2x-3y=-2

Which graph represents this system 2x-5y=-5 y=2/5x+1
olga_2 [115]

Answer: option D

The last option

Step-by-step explanation:

Which graph represents this system 2x-5y=-5

y=2x/5+1

Comparing the equation with the slope intercept equation, y= mx + c,

The slope,m = 2/5

From the graph, slope = (change in value of y)/ (change in value of x)

= (y2 - y1) / (x2-x1)

y2 = 1

y1 = 0

x2 = 0

x1 = 2.5

Slope, m =( 1-0)/(0 - - 2.5) = 1/(0+2.5)

= 1/2.5

Multiply numerator and denominator by 2

m= (1×2)/(2.5×2)

= 2/5

This corresponds to the slope of the equation given at the beginning.

Leviafan [203]
Let c represent the speed of the current.

time = distance / speed

total time = time going upriver + time going downriver
2 2/3 = 6/(9 -c) + 6/c
(8/3)(c)(9 -c) = 6c +6(9 -c)
(8/3)c^2 -24c +54 = 0
c = (24 ± √((-24)^2 -4(8/3)(54)))/(2*8/3)
.. = (3/16)(24)
c = 4.5

The speed of the river's current is 4.5 km/h.

shutvik [7]

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}

t_{1} =  \frac{d}{v_{1}} =  \frac{240}{60} = 4 \: hours  \\ t_{2} =  \frac{d}{v_{2}}  =  \frac{240}{40}  = 6 \: hours

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}  =  \frac{40 - 60}{6 - 4}   =  \frac{ - 20}{2}  =  - 10
