What is the value of the rewritten expression when a = -5?
Answer:
-500
Step-by-step explanation:
(2a^4)^2
-----------------
a^0 a^5
We know ( xy) ^z = x^z y^z
so
(2a^4)^2 = 2^2 a^4^2
and x^y^z =x^(y*z) so a^4^2 = a^(4*2) = a^8
(2a^4)^2 = 4 a^8
We know that a^0 = 1
4 a^8
-----------------
1 a^5
We know x^y / x^z = x^ ( y-z)
4 a^( 8-5)
4 a^3
Let a = -5
4 ( -5) ^3
4 ( -125)

Can I get some help plz?
Answer:
X=20 degree
Step-by-step explanation:
∆A+∆D+∆O=180
2x+10+2x+90=180
collect like terms
2x+2x=180-100
4x=80
(4x)/4=(80)/4
x=20 degree
Answer:
[tex]angles \: of \: triangle \: add \: up \: to \: {180}^{0} \\ {(2x + 10})^{0} + {(2x)}^{0} + {90}^{0} = {180}^{0} \\ 4x = {(180 - 90 - 10)}^{0} \\ 4x = {80}^{0} \\ x = {20}^{0} [/tex]
14. The figure shows a slice of an apple pie in the shape of a sector of a circle with centre O and radius 8cm. A cut is made along AB to remove some of the crust
Given that AB = 7 cm find:
(i) AOB in radians
(ii) the maximum number of slices that can be obtained from one full pie.
(iii) the area of the shaded segment that has been removed
Step-by-step explanation:
(i) Using the law of cosines, we can find that
[tex]cos(O) = \frac{8^{2}+8^{2} - 7^{2}}{8*8*2}[/tex] ≈ 0.62, so O ≈ 0.9
(ii) Since the whole pie has 2π radians (or 360 degrees), we can divide 0.9 by 2π to get around 6.9 slices from the pie
(iii) The area of the shaded segment can be found by finding sector OAB and subtracting triangle OAB from that. Sector OAB can be found by finding the area of the pie (π*8², since 8 is the radius) and dividing that by 6.9, so we get 64π/6.9 ≈ 29. Then, the area of the triangle is √p(p-a)(p-b)(p-c), with p being the perimeter and a, b, and c being the sides. Plugging 7, 8, and 8 in, we get 25.1781 as our area, so the difference is around 3.8
A salesman gets a basic wage of £160 per week plus a commision of 30%
of the sales he makes that week.
In one week his total wage was £640
Work out the value of the sales he made that week.
Answer:
The value of the sales that week was £1,600
Step-by-step explanation:
The wage of a salesman is made of two parts: A fixed-wage of £160 per week plus a commission of 30% (0.3) of the sales he makes that week.
The wage can be modeled by the function:
W = 160 + 0.3x
Where x is the amount of sales per week.
If he had a total wage of £640, then we can find the values of the sales by solving for x the equation
160 + 0.3x = 640
Subtracting 160:
0.3x = 640 - 160
0.3x = 480
Dividing by 0.3:
x = 480/0.3
x = 1,600
The value of the sales that week was £1,600
find the value of x
Answer:

What is the x-coordinate of the point where the graphs of y = 8 and y = 2x intersect?
Answer: 7
Step-by-step explanation:
Answer:
⬇️⬇️⬇️
Step-by-step explanation:
2x + y = 8 is the equation of a straight line. ... By substituting y = 0 into the equation we will find the corresponding x-coordinate at this point. y = 0 : 2x = 8 and so x = 4 hence point (4 , 0 ) on the x-axis

–2x – 4x + 8y – y
(–2 – 4)x + (8 – 0)y
–6x + 8y
Answer:
Step-by-step explanation:
2) They distributed an x out of the term with out one. that is the 8
so the expression should be 5x +8
3) They didn't follow order of operations and took 2 away from the 7 before they distributed the 7 :O very bad of them
the expression should be 7x + 54
4) They distributed out the y but didn't leave a 1 so the problem lost a term.
the expression should be -6x + 7y

The number line that represents opposite numbers is (a) number line 1
How to determine the number line?From the question, we understand that:
The numbers are opposite numbers
Take for instance, we have a number x.
The opposite of the number x is -x
So, the number line that represents opposite numbers must have points at x and -x
Let x = 10.
So, we have:
Opposite numbers = 10 and -10
So, the number line that represents opposite numbers must have points at 10 and -10
Hence, the number line that represents opposite numbers is (a) number line 1

Answer:
9
Step-by-step explanation:
For the equation to have more than one solution, that is infinite solutions, then both sides should be equal.
left side is
5u + 3(4u - 6)
= 5u + 12u - 18 = 17u - 18
right side is
- 3u - 27 + 20u
= 17u - 27 ← require to add 9 so equal to left side, that is
17u - 27 + 9
= 17u - 18
