Answer:

Step-by-step explanation:

4x -39 > -43 8x + 31 < 23

Add 39 to both sides Subtract 31 from both sides

4x -39 + 39 > -43 + 39 8x + 31 - 31 < 23 - 31

Simplify Simplify

4x > -4 8x < -8

Divide both sides by 4 Divide both sides by 8

4x / 4 > -4 / 4 8x / 8 < -8 / 8

Simplify Simplify

x > -1 x < -1

The equation for a parabola has the form y=ax2+bx+c, where a, b, and c are constants and a≠0. find an equation for the parabola

IRISSAK [1]

The equation of parabola is

$y= ax^2 + bx +c$

For point (-1,-9), equation of parabola is

$-9 = a(-1)^2 +b(-1)+c
\\
-9 = a -b+c$

For point (1,7), equation of parabola is

$7 = a(1)^2 + b(1)+c
\\
7 = a + b +c$

For point (-6,-14), equation of parabola is

$-14 = a(-6)^2 +b(-6)+c
\\
-14 = 36a -6b +c$

So we have three equations , which are

$a - b + c =-9,
\\
a + b + c = 7
\\
36a -6b+c = -14$

Subtracting first two equation will give

$-2b = -16
\\
b=8$

Subtracting second and third equation gives

$a+b+c-36a+6b-c = 7+14
\\
-35a +7b = 21
\\
-5a + b =3$

Substituting 8 for b, we will get

$-5a + 8 =3
\\
-5a = -5
\\
a =1$

back substituting 8 for b and 1 for a, we will get

$1+8+c = 7
\\
c = -2$

So we have

$a=1, b=8 and c=-2$

Therefore required equation is

$y= x^2 +8x-2$

Answer:

4.2 miles

Step-by-step explanation:

Using the pythagorean theorem, a^2 + b^2 = c^2

youll get 3.6^2 + 2.2^2 = 17.8

sqrt of 17.8 = 4.2
