In-s [12.5K]

Answer:

1) d < -2

2) b < 3

Step-by-step explanation:

1) d+3< 1

subtract both sides by 3

d+3 -3 < 1-3

d<-2

2) b+6< 9

subtract both sides by 6

b+6 -6 < 9 -6

b< 3

Help me fill this out thanks

alukav5142 [94]

Answer:

This is an isosceles right triangle, then we have

2 x u^2 = [6sqrt(2)]^2

<=> 2 x u^2 = 72

<=> u^2 = 36

<=> u = 6

Hope this helps!

Help someone please!! don’t understand

Citrus2011 [14]

Radical 2 = 1.4 So 1.4 * 6 = 8.4

a^2 + b^2 = c^2

8.4^2 + 8.4^2 = square root of c

70.56 + 70.56 = 141.12 ≈ 141

Then you must find the square root of 141 which is 11.874 ≈ 11.9

Side a = 8.4
Side b = 8.4
Side c = 11.9

The parabola y = x² - 4 opens: A.) up B.) down C.) right D.) left

fomenos

Answer:

Step-by-step explanation:

Here the easy rules to remember the orientation of the parabolas are

a) If x is squared it opens up or down. And its coefficient of { $x^{2}[tex] is negative it opens down.b) If y is squared it opens side ways right or left. It its coefficient of [tex]y^{2}$

Hence in our equation of parabola

$y = x^ 2-4$

x is squared and its coefficient is positive , hence it opens up towards positive y axis.
