Solve each equation by graphing the related function. If the equation has no real-number solution,write no solution .

1 answer:

3 0

See each answer below.

1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.

2) Dividing by 3 and taking the square root gives an answer of 0.

3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.

4) Divide by 4 and then take the square root. You have positive or negative 5/2.

Answer:

Inequality 1:

Inequality 2:

Step-by-step explanation:

Step-by-step explanation: To write inequalities using a graph, remember these tips: If the line is solid, the equality symbol will be either ≤ or ≥. If the line is dashed, the equality symbol will be either < or >. When the shaded area is above the line the equality symbol will be > or ≥. When the shaded area is bellow the line, the equality symbol will be < or ≤.

Two groups went hiking, leaving at the same time and arriving back at the same time. While one group moved away at the speed 6 m

Evgesh-ka [11]

Step-by-step explanation:

d = the distance in one direction.

the time t1 it took group 1 was

t1 = d/6 + d/4

and t2 for group 2 moving with speed2 all the way

t2 = (d+d)/speed2

we know

2d = 24 miles

d = 12 miles

t1 = t2

so,

12/6 + 12/4 = 24/speed2

2 + 3 = 24/speed2

5 = 24/ speed2

5×speed2 = 24

speed2 = 24/5 = 4.8 mph

the second group moved with 4.8 mph.
