Answer:
-2/a^3
Step-by-step explanation:
Anything (except 0) to the 0 power is 1, so b^0 = 1. This immediately simplifies the expression to -2a^-3. If you also want it with positive exponents, this will be ...
-2/a^3
What is the equation of the line that passes through the point -6 -5 and has a slope of 3/2
Answer:
y = (3/2)x + 4
Step-by-step explanation:
The equation for a line is y = mx + b. m is the slope, b is the y-intercept, and y and x are points.
First, substitute in the slope.
y = (3/2)(x) + b
Then, substitute in the points.
-5 = (3/2)(-6) + b
Multiply.
-5 = -9 + b
Add 9 to both sides.
b = 4
Therefore...
y = (3/2)x + 4
550 tickets were sold for a game for a total of $712.50. If adult tickets sold for $1.50 and children's tickets sold for $1.00, how many of each kind of ticket were sold?
9514 1404 393
Answer:
adult: 325children's: 225Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
Is 13 ft the correct length?
Answer:
Your answer is incorrect 22 ft is correct
Step-by-step explanation:
We can check if 13ft is correct by using the volume formula and seeing if it equals the volume given
so volume is
width * length * height
if the length is 13
lets try it!
8 * 13 * 5
= 520 this is not correct the volume stated is 880
Let's try the next answer 22 ft
8 * 22 * 5
= 880
22 ft works that will be your answer
hope this helps!

Step-by-step explanation:
[tex]\frac{88}{66} * \frac{8}{13} * \frac{26}{7}[/tex] [tex]\frac{4}{3}*\frac{8}{13} * \frac{26}{7}[/tex] [tex]\frac{32}{39} * \frac{26}{7}[/tex] [tex]\frac{832}{273}[/tex] [tex]\frac{832}{273} = \frac{64}{21}[/tex] [tex]\frac{64}{21} = 3\frac{1}{21}[/tex]Therefore, the answer is 3 1/21 or 64/21.

С
Question 3 (2 points)
Answer:
3 1/3
10/3
3.333
Step-by-step explanation:
These two triangles are similar. Since they share two angles, the right angle and angle EBD and ABC are congruent. By AA similarity rule, they are similar triangles.
Since they are similar we can set up a proportion of the triangles since similar triangles have proportional side length.
Side AC corresponds with DE
Side AB corresponds with BE
Side BC corresponds with BD
So we can use this proportion theorem, or angle bisector theorem
[tex]\frac{ac}{ab}=\frac{de}{be}[/tex]
Plug in the numbers.
[tex]\frac{3}{5} =\frac{2}{x}[/tex]
Cross multiply
3x=10
x=10/3
Simplify is
3 1/3
As a decimal it equal 3.333

Evaluate x(y+3)/(3+y)z for x=12, y=1, and z=6.
A) 2
B) 5
C) 8
D) 6
Answer:
2
Step-by-step explanation:
We take the equation
[tex]x(y+3)/(3+y)z[/tex]
and substitute the values for each individual variable in the problem. It looks like this:
[tex]12(1+3)/(3+1)6[/tex]
Now we can solve the equation.
When solved, it equals 2.

The value of solution of equation is,
⇒ x = ±1 and x = ±√2
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Expression is,
⇒ x⁴ - 3x² + 2 = 0
Now, We can plug x² = u in above equation and solve as;
⇒ x⁴ - 3x² + 2 = 0
⇒ u² - 3u + 2 = 0
⇒ u² - 2u - u + 2 = 0
⇒ u (u - 2) - 1 (u - 2) = 0
⇒ (u - 1) (u - 2) = 0
⇒ u = 1
⇒ u = 2
Plug x² = u
⇒ x² = 1
⇒ x = ±1
⇒ x² = 2
⇒ x = ±√2
Thus, The value of solution of equation is,
⇒ x = ±1 and x = ±√2

a line passes through the point (-3,-7) and has a slope of 6 write an equation in slope intercept form for this line.
9514 1404 393
Answer:
y = 6x +11
Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx +b . . . . . . m = slope, b = y-intercept
Solving this for b, we get ...
b = y -mx
b = -7 -6(-3) = -7 +18 = 11 . . . . . . using the given point and slope
Then the desired equation is ...
y = 6x +11
h= -16t^2+16t+192 When will the ball hit the ground?
Answer:
t = 4 s
Step-by-step explanation
We can infer the origin from the t⁰ term of the quadratic as being 192 feet above the ground. Initial velocity is 16 ft/s from the t¹ term, gravity is -32 ft/s² from the t² term
0 = -16t² + 16t + 192
0 = -t² + t + 12
0 = t² - t - 12
0 = (t - 4)(t + 3)
so either
t - 4 = 0
t = 4 s
or
t + 3 = 0
t = -3 s which we ignore as it occurs before the ball is released.
Carlos has 24 balls of different colors: yellow, red, green, and blue. 17 balls are not red,10 balls are neither yellow nor blue. How many green balls does Carlos have
pls help(if u can pls also explain it)
Answer:
10 green
Step-by-step explanation:
24 total balls. 17 Not red, so 24-17=7. 7 Red balls. That leaves 17 balls. 10 of them are neither yellow nor blue, and since the amount of red balls has been figured out, we do not need to account for them. 17 balls - 10 not yellow or blue equals 7 balls that can be yellow or blue. 17 balls left, minus the 7 yellow or blue balls equals 10.
Super easy please answer
Answer:
the answer is c) 2n+8
Step-by-step explanation:
This is because the expession applies to every figure when calculating the amount of sides
figure 1- 2(1)+8 = 2+8 = 10
figure 2- 2(2)+8 = 4+8 = 12
figure 3- 2(3)+8 = 6+8 = 14
Yes, the expression is true for every figure, proving that it can solve for the perimeter

Use the given formula to calculate each option and compare.
Option 1
P = $210000r = 8.5% = 0.085t = 30n = 1Find the PMT:
[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.085)/(1-(1+0.085)^{-30})=19541[/tex]Find the total interest amount:
30*$19581 - $210000 = $377430Option 2
P = $210000r = 8% = 0.08t = 20n = 1Find the PMT:
[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.08)/(1-(1+0.08)^{-20})=21389[/tex]Find the total interest amount:
20*$21389 - $210000 = $217780We see option 2 reveals less interest amount, so is more economical.
