Solve by factoring x^4+6x^2-27=0
Answer:
Step-by-step explanation:
x^4+6x^2-27=0
The two factors you need to use for 27 is 9 and 3.
Since the middle term must be plus then the 9 is also plus.
(x^2 + 9)(x^2 - 3)
x^2 + 9 can't be factored in the real number system.
x^2 - 3 = 0
(x + sqrt(3))(x^2 - sqrt(3))
The full factoring answer would be
(x^2+9)(x + sqrt(3))(x^2 - sqrt(3))

5x + 3y, when x = 4, and y=-3
Answer:
5x+3y, when x=4 and y= -3
5(4)+3(-3)=
20+ (-9)=
11
Step-by-step explanation:
Hope this helps. :)
Answer:
5x + 3y = 11
Step-by-step explanation:
x = 4 y = -3
=5x + 3y
=5(4) +3(-3)
=20 + (-9)
=11
When a number and variable are right beside each other it means that the number and the variable are being multiplied together, for example 5x. If x = 4 then it means that 5 and 4 are being multiplied.

Along the U.S. Atlantic coast, the sea level is rising about 2 millimeters per year. Joe is 13 years old. How many millimeters has sea level risen since Joe was born?
Solve the equation for the variable.
[tex]49 - \frac{2}{3} x = 32 - \frac{1}{6} x[/tex]
x = [?]
Answer:
1) Take LCM
(147-2x)/3 = (192-x)/6
2) Cross multiply
882-12x= 576-3x
3) Rearrange
882-576= 12x-3x
306= 9x
x=306/9
x=34

Joanne has a cell phone plan that charges a flat rate of $97 and $0.10 for every text she sends. Her goal is to spend less than $113 on her phone bill each month. Which of the following describes the number of texts she sends? (2 points)
a.) at least 160
b.) no more than 160
c.) fewer than 160
d.) more than 160
Answer:
c because she wants to spend less than 113 and if she sent 160 that would be 113 so has to be less
Step-by-step explanation:
113>97+.1x
16>.1x
160>x
Apply the dilation (x, y) = (3x, 3y). What will be the coordinates of T'?
Answer:
6,0
Step-by-step explanation:
the dilation moves points from A to B
in this case we're moving point T
point T has coordinates 2,0 to start with (A)
Now let's move it to B
To do so, we need to apply the calculation
(x,y) => (3x,3y)
Substitute in point T:
(2,0) => (3x,3y)
(2,0) => (3(2),3(0))
(2,0) => (6,0)
Find the distance between the points (0,-8) and (8,-3). The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The distance in radical expression form is d=[tex]\sqrt{89}[/tex]
Step-by-step explanation:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-0)^2+(-3-(-8))^2}\\d=\sqrt{(8)^2+(5)^2}\\d=\sqrt{(64)+(25)}\\d=\sqrt{89}\\[/tex]
Your cell phone plan costs $24..99 per month plus $0.17 for each text message you send or receive. You have at most $29 to spend on your cell phone bill. What is the maximum number of text messages that you can send or receive next month?
Answer:
The maximum number of text messages you can send per month would be 23.
Step-by-step explanation:
1. First, you want to create an inequality from the word problem. You know that $24.99 is a constant, so we won't put any variables next to it. You also know that each text message is $0.17, so that would need a variable since it can change each month. You also know that you can spend $29 maximum each month, so that goes on the other side of the inequality. Your inequality will look like this: 0.17x+24.99≤29 (x is the number of text messages).
2. Second, you want to solve for x. To do this, subtract 24.99 from each side. After this, the equation is 0.17x≤4.01
3. Now, divide each side by 0.17. Now your inequality is x≤23.59. This represents how many text messages you can send per month without going over 29.
4. Finally, you have to realize that is impossible to send exactly 23.59 text messages. So, you have to round down to 23 to get an even number of text messages, and that's your answer!
Hope this helps! Feel free to ask any questions :)
Solve using 2-step equations.
You work as a salesperson at Cutco, and earn only commission. You earn 30%
commission on everything you sell. Your bills this month are $1,800 and you
also want to put $500 into your savings.
How much do you need to sell at your job to make sure you can pay your
bills and still have enough to save?
Answer:
$7666.7
Step-by-step explanation:
1800 + 500 = 2300. That means that 30% = 2300. If u divide both sides by 3 then 10% = 766.67 times that by ten and then that will equal $7666.7
HELP NEEDED: Will mark Brainliest to best answer!! The center of a dilation is (0,0) and the scale factor is 7. If A(3,4), then which is the distance between A and A prime? A. 5 B. 7 C. 30 D. 35
Answer:
C. 30
Step-by-step explanation:
Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.
3•7 = 21=x --> A prime = (21,28)
4•7 = 28=y
[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]
= [tex]\sqrt{324+676}[/tex]
= [tex]\sqrt{900}[/tex]
= 30

[tex]-\frac{6}{5}(4 - x) \leq -4(x + \frac{1}{2} )[/tex]
Let's start off by distributing the [tex]-\frac{6}{5}[/tex] and -4
[tex]-\frac{24}{5} + \frac{6}{5}x \leq -4x - 2[/tex]
Add 4x and [tex]\frac{24}{5}[/tex] to both sides.
[tex]\frac{26}{5}x \leq \frac{14}{5}[/tex]
Divide both sides by [tex]\frac{26}{5}[/tex]
[tex]x\leq \frac{7}{13}[/tex]

Which revision changes the sentence from passive voice to active voice?
The new art gallery in our city was visited by several politicians and celebrities to raise money for charity.
OA. Visited by several politicians and celebrities, our city's new art gallery raised money for charity.
OB. The new art gallery in our city raised money for charity by the visits of several politicians and celebrities.
OC. To raise money for charity, the new art gallery in our city was visited by several politicians and celebrities.
OD. Several politicians and celebrities visited the new art gallery in our city to raise money for charity.
Answer:
They all have the passive word, "Visited," so that makes everything a bit more complicated. I can see why you asked the question. I'd go with C. Unless it's a trick question and you're supposed to see that or something.
Use the distributive Property to simplify: (x-7)(x-8)
Answer:
[tex]x^2-15x+56[/tex]
Step-by-step explanation:
Use the FOIL distributive method: [tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
---------------------------------------------------------------------------------------------
Thus, [tex]\left(x-7\right)\left(x-8\right)=x\times x +x\left(-8\right)+\left(-7\right)x+\left(-7\right)\left(-8\right)[/tex]
Multiply them to get:
[tex]x^2-8x-7x+56[/tex]
[tex]x^2-15x+56[/tex]
9.6= 1.2b find b please show work
PLEASEEEE
Answer:
8
Step-by-step explanation:
1.) 9.6=1.2b
2.) 9.6/1.2=1.2b/1.2
3.)b=8
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{b = 8}}}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf{ \: \: \: 9.6 = 1.2b}}[/tex]
Swap the sides of the equation
[tex] \hookrightarrow{ \sf{1.2b = 9.6}}[/tex]
Divide both sides by 1.2
[tex] \hookrightarrow{ \sf{ \frac{1.2b}{1.2} = \frac{9.6}{1.2} }}[/tex]
Calculate
[tex] \hookrightarrow{ \bold{ \boxed{ \sf{b = 8}}}}[/tex]
The value of b is 8
