Answer:
[tex]x=+2i\sqrt{14}\ \ \,x=-2i\sqrt{14}[/tex]
Step-by-step explanation:
[tex]-3x^2-168[/tex]
The first step in solving this equation is the factor, remove a factor that both the quadratic and constant term have in common. In this case, such a term would be (-3),
[tex]-3(x^2+56)[/tex]
Now set the equation equal to zero so that one can use the zero product property. The zero product property states that any number times zero equals zero.
[tex]-3(x^2+56)=0[/tex]
Solve, use inverse operations,
[tex]x^2+56=0[/tex]
[tex]x^2=-56[/tex]
One cannot take the square root of a negative number and get a real result, thus the result is an imaginary number.
[tex]x=\sqrt{-56}[/tex]
Simplify, remove whole factors from under the radical,
[tex]x=+-2i\sqrt{14}[/tex]
solve and graph: 7x-6>22
(pls explain your answer, im confused on this)
Answer:
x>4
Step-by-step explanation:
Solving an inequality is very similar to solving an equation:
Given: 7x-6>22
Add 6 to both sides: 7x>28
Divide both side by 7: x>4
x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

This table goes through the pairs(51,-65) and (68,-78).What is the yintercept of the line?
Answer:
I think the y intercept is (0,-26)
Step-by-step explanation:
Answer:
(0, -26)Step-by-step explanation:
Find the slope:
m = (-78 + 65)/(68 - 51) = -13 / 17Use point-slope form to find the equation of the line:
y - (-65) = -13/17(x - 51)y = -13/17x + 39 - 65y = -13/17x - 26The y-intercept is - 26

I would really appreciate if any of you guys can help me on this please and thank you !!
Answer:
1.
a = 1 b = 3 c = 11
2.
a = 1 b = -7 c = -11
3.
a = 1 b = 4 c = -9
4.
a = 3 b = -1 c = 16
5.
a = 1 b = 0 c = -9
6.
a = 2 b = 5 c = 0
7.
a = -4 b = 0 c = -3
8.
a = 6 b = 0 c = 0
9.
a = -1 b = 1 c = 0
Hope this helps took me a long time to type

earlier you saw a situation where the total number of times a dog has barked was a function of time, in seconds, after it's owner tied it's leash to a post and left. less than 3 minutes and walked away with the dog l. could 300 be an input of function? explain why or why not
9514 1404 393
Answer:
no; 300 is not in the domain of the function
Step-by-step explanation:
If the function is defined for times less than 3 minutes, and the input is given in seconds, the function is only defined for inputs up to 180. An input of 300 is not in the domain of the function.

9 - (4/9+1/3)
Write and solve a word problem for the expression
Answer:
9 pizzas total were bought for a party. Maya ate 1/3 of a pizza. John ate 4/9 of the same pizza. How much pizza is left?
Answer: 74/9 or 8.2
Step-by-step explanation:
first add 4/9 and 1/3 since it's in parenthesis
4/9+1/3
they need to have the same denominator, use the LCM (which is 9)
multiply 1/3 by 3 to achieve the LCM
4/9+3/9
add together numerators
7/9
subtract 7/9 from 9
9/1-7/9
get 9 to achieve the LCM (which is 9 again)
multiply 9/1 by 9
81/9 minus 7/9= 74/9
