Answer:
11x+11y-4
Step-by-step explanation:
Match the following sentences on the left with their algebraic expression on the right.
a. The product of 5 and the sum of a number and 8
Product means multiplied, so that means 5 multiplied by some number plus 8, thus, 5(x+8)
b. A number less than 12
12-x would equal less than
c. The product of five and a number divided by 2
Again, product means multiplied, so its saying 5 times something, all divided by 2, thus, 5x/2
Please give brainliest :) hope this helps!
Answer:
A number less than twelve = 12 - x = b
The product of five and a number divided by two = 5x/2 = c
The product of five and the sum of a number and eight = 5(x+8) = a
Step-by-step explanation:
A number less than twelve
12 minus a number
12 - x
The product of five and a number divided by two
A number times 5 divided by 2
5x/2
The product of five and the sum of a number and eight
A number plus 8 times 5
(x+8)*5
5(x+8)

If you have 1/4 of a pie left and you give away 5/8 how much pie do you have left
Answer:
You cannot give away more than you have. You have no pie left.
Step-by-step explanation:
1/4 - 5/8
Multiply 1/4 by 2 to get a common denominator in order to subtract.
2/8 - 5/8
= -3/8
You can't have -3/8 of a pie.
Therefore, you have no pie left.

Step-by-step explanation:
21. x² - 4x - 5 > 0
→ (x - 5) (x - 1) > 0
{x - 5 > 0
{x + 1 > 0
{x - 5 < 0
{x + 1 < 0
{x > 5
{x > -1
{x < 5
{x < -1
= x < -1 or x > 5
therefore, option A is correct
22). 4p² - 1 ≤ 0
(2p - 1) (2p + 1) ≤ 0
{2p - 1 ≤ 0
{2p + 1 ≥ 0
{2p - 1 ≥ 0
{2p + 1 ≤ 0
{p ≤ 1/2
{p ≥ -1/2
{p ≥ 1/2
{p ≤ -1/2
1/2 ≤ p ≤ 1/2
{p ≥ 1/2
{p ≤ -1/2
-1/2 ≤ p ≤ 1/2
therefore, option A is correct.
23). y < 3x² + 3x - 6
3x² + 3x - 6 = 0
3x² + 6x - 3x - 6 = 0
3x(x +2) - 3(x +2) = 0
(x +2) (3) (-3) = 0
x = -2, 1
this is the correct ans. but their is no option similar to it.
25. x and y are root of
m² - 11m + 18 = 0
hence, x + y = 11
xy = 18
2xy = 36
now, x² + y²
= (x +y)² - 2xy
= (11)² - 36
= 121 - 36
= 85
therefore, option A is correct.
26. x² - 2x - 120
(x -1)² - 1 - 1² = 0
(x -1)² = 1 + 1²
x - 1² = 2
x - 1 = ±√2
1 ± √2
therefore, option A is correct.
hope this answer helps you dear..take care!
Answer:
Step-by-step explanation:
21) x² - 4x - 5 > 0
x² - x + 5x - 5 > 0
x(x - 1) + 5(x - 1) > 0
(x - 1) (x + 5) > 0
x - 1 >0 or x + 5 > 0
x > 1 or x > - 5 Ans: D
22) 4p² ≤ 1
p² ≤ 1/4
p ≤ 1/2 or p ≥ -1/2
-1/2 ≥ p ≤ 1/2
23)y < 3x² + 3x - 6
(1 , -7)
x = 1 and y = -7
-7 < 3*1 + 3*1 - 6
-7 < 3 + 3 - 6
-7 < 0
(1 , -7) satisfies the equation.
Option b
24) 5x² - 7x = 0
a = 5 ; b = -7 ;c = 0
Discriminant = b² - 4ac = 49 - 0 = 0
[tex]x = \dfrac{-b+\sqrt{D}}{2a} \ ; \ \dfrac{-b-\sqrt{D}}{2a}\\\\x = \dfrac{7+\sqrt{49}}{10} ; \dfrac{7-\sqrt{49}}{10}\\\\x = \dfrac{7+7}{10};\dfrac{7-7}{10}\\\\x =\dfrac{14}{10} ; 0\\\\x = \dfrac{7}{5}; 0[/tex]
x = 0 ; x = 7/5 Option a)
25) m² - 11 m + 18 = 0
m² - 2m - 9m + (-9)*(-2) = 0
m(m - 2) - 9(m - 2) = 0
(m - 2)(m - 9) = 0
m = 2 , 9
x = 2 and y =9
x² + y² = 2² + 9² = 4 + 81 = 85 Option a)
26) x² - 2x - 1 = 0
Add the constant 1 to both sides
x² - 2x = 1
Divide the coefficient of x by 2. 2/2 = 1. Now add this 1 to both sides of the equation.
x² - 2x + 1 = 1+1
x² - 2x + 1 = 2
(x - 1)² = 2
Take square root
x - 1 = ±√2
x = 1 ± √2 Option a)

Answer:

4 were sold
3 more gray were sold than white
3 colors sold 10 or more
Answer:
a) White
b) 3
c) 3
Step-by-step explanation:
a) White as it is the shortest bar (has the lowest height and only has 4 t-shirts sold)
b) According to the bar graph, 7 grey t-shirts were sold and 4 white t-shirts were sold. Subtracting 4 from 7 = 7-4 = 3
Hence, 3
c) At least 10 T-shirts sold, suggests that it was greater than or equal to 10. According to the graph, black has 12, tan has 11, and brown has 10. Hence,
3 colors had at least 10 t-shirts sold.

Answer:
domain is the set of numbers you can use for x
Step-by-step explanation:
log_4(x+3)=y means
I mean it translates to
4^y=x+3
remember that x^m≥0 for all real values of x and m
it actually can equal 0 only when x=0 or when x is very small
so
therefor since 4^y>0, x+3>0 as well
solving we get
x>-3
all real numbers greater than -3

apply the rules of exponents to the problem in BOTH radical form and rational exponent
form true or false
Answer:
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^½. In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.For the denominator, that deals with the radical. The index, to be exact. The index describes what kind of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3).^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Step-by-step explanation:
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)

The probability of number greater than [tex]12[/tex] is zero.
What is probability ?Probability is the ratio of number of favorable outcome to the total number of outcome.
We have,
Total number of outcome [tex]=12[/tex]
And number of greater than [tex]12[/tex] [tex]=0[/tex]
So,
Probability [tex]=\frac{Number\ > \ 12}{Total\ number}[/tex]
[tex]=\frac{0}{12}[/tex]
Probability [tex]=0[/tex]
A probability of [tex]0[/tex] means that the event will not happen.
Hence, we can say that the probability of number of greater than [tex]12[/tex] is zero.
