Answer:

c is the answer

Step-by-step explanation:

so we know one equation

y=6x+15

we need to find the other one

24-10=14

14 miles in 2 hours

7 miles in 1 hour

y=7x+10

henry's ballon begins at 10 miles from the town and is 24 miles from the town in 2 hours

Where henry starts is 10 the y-intercept

look at the slopes

Henry: y=7x+10

Tasha: y=6x+15

Tasha starts farther away

Henry goes farther

Answer:

2<x<3

Step-by-step explanation:

4x-4<8 AND 9x+5>23

Solve the first inequality

4x-4<8

Add 4 to each side

4x-4+4 <8+4

4x<12

Divide by 4

4x/4 <12/4

x <3

Solve the second inequality

9x+5>23

Subtract 5 from each side

9x+5-5>23-5

9x >18

Divide by 9

9x/9>18/9

x>2

Put together

Y=2(x+1)^2 has how many real roots

oee [108]

The equation y= 2 $(x+1)^2$ has one real root and that is x=-1.

What is real roots of the equation?

We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation $X^2$ -7x+12=0 is solved, the actual roots are 3 and 4.
