Julian counted the numbers of times he drove across the seven mile bridge while vacationing in the florida keys. he crossed the beige 34 times. how much miles in all did julian drive crossing the bridge

He drove 238 miles while crossing the bridge.

Step-by-step explanation:

Since we have given that

Number of miles that bridge has = 7 miles

Number of times Julian crossed = 34

We need to find the number of miles that he drive while crossing the bridge.

So, Number of miles that he drove is given by

Number of miles that bridge has × Number of times he crossed

Hence, he drove 238 miles while crossing the bridge.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

the answer is c just got it on ed
