Solution for (-4z^2-11u)-5z^2=
<span>Simplifying (-4z2 + -11u) + -5z2 = 0
 Reorder the terms: (-11u + -4z2) + -5z2 = 0
  Remove parenthesis around (-11u + -4z2) -11u + -4z2 + -5z2 = 0
  Combine like terms: -4z2 + -5z2 = -9z2 -11u + -9z2 = 0 Solving -11u + -9z2 = 0 Solving for variable 'u'.
 Add '9z2' to each side of the equation. -11u + -9z2 + 9z2 = 0 + 9z2 Combine like terms: -9z2 + 9z2 = 0 -11u + 0 = 0 + 9z2 -11u = 0 + 9z2
 Remove the zero: -11u = 9z2 Divide each side by '-11'. u = -0.8181818182z2 Simplifying u = -0.8181818182z<span>2</span></span>

-4(2x + 4) &gt; 8x + 64
romanna [79]

Hello there I hope you are having a great day :)

Your Question, -4(2x + 4) > 8x + 64 Solve for X

1) Expand -8x-16>8x+64

2) Add 16 to both sides -8x-16+16>8x+64+16

3) Simplify -8x>8x+80

4) Subtract 8x from both sides -8x-8x>8x+80-8x

5) Simplify -16x>80

6) Multiply both sides -1 (Reverse the inequality) (-16x) (-1) >80 (-1)

7) Simplify 16x<-80

8) divide both sides by 16   16x/16 <  -80/16

9) Simplify x < -5  

This should be your answer x < -5

Hopefully that helps you :)

5 A triangle has two congruent angles. The length of one
nlexa [21]

Answer:

<em>Answer: C. 32 cm</em>

Step-by-step explanation:

<u>Triangle Inequality Theorem </u>

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We know the triangle has two congruent angles, which means the triangle is isosceles, i.e., it has two congruent sides.

We are given two side lengths of 16 cm and 32 cm. The third side must have a length of 16 cm or 32 cm for the triangle to be isosceles.

If the third side had a length of 16 cm then the lengths would be 16-16-32. But that combination cannot form a triangle because of the condition stated above.

If y=16, z=16, and x=32 (the worst possible combination), then the inequality

0 < x < 32

wouldn't be satisfied, thus the third side cannot have a length of 16 cm and it must have a length of 32 cm

Answer: C. 32 cm

Suppose that you plan on investing into a account paying simple interest. The formula for simple interest is I = Prt, where I is
Vedmedyk [2.9K]

Answer:

No

Step-by-step explanation:

No.

i = prt is correct; its result is the simple interest earned.  

If you want to solve for time, t, divide both sides by pr:

i/(pr) = t

Solve the formula x-2y=15 for y
umka2103 [35]

Answer:

y = (1/2)x - (15/2)

Step-by-step explanation:

goal: to rearrange the expression such that it is in the form

y = f(x); where f(x) is an expression in terms of x

given:

x - 2y = 15      (subtract x from both sides)

-2y = 15 - x    (multiply both sides by -1 to make left side positive)

2y = -15 + x   (divide both sides by 2 and rearrange)

y = (1/2)x - (15/2)
