When multiplying exponents, remember the first rule: when multiplying similar bases, add powers together. 52% + 56% =? The bases of the equation remain unchanged, while the exponents' values are added together. Adding the exponents is only a quick way to get at the answer. Simply add the exponents to multiply exponential expressions with the same base. Simplify. The product rule applies because the base of both exponents is a. With a common basis, add the exponents.

[tex]15x - 10 = 10 + 6 + 2x[/tex]
[tex]15x - 10 = 16 + 2x[/tex]
Plus sides 10
[tex]15x - 10 + 10 = 2x + 16 + 10 \\ [/tex]
[tex]15x = 2x + 26[/tex]
Subtract sides -2x
[tex]15x - 2x = 2x - 2x + 26[/tex]
[tex]13x = 26[/tex]

Three more than twice a number is less than negative nineteen. Solve the inequality for the unknown number.
Answer:
-12.5
Step-by-step explanation:
You wanna do it inverse backwards
-19 divided 2 = -9.5
-9.5 minus 3 = -12.5
Write the equation of the line that passes through the points
(-2, -1) and (2, 4). Put your answer in fully reduced point-
slope form, unless it is a vertical or horizontal line.
Answer:
Step-by-step explanation:
Step 1 : Find the slope/gradient (this is known as "m")
The slope formula is :
[tex]m = \frac{y2 - y1}{x2-x1}[/tex]
*Note that we are given 2 points:
For the first point (-2,-1) , this means x1 = -2 and y1 = -1
For the second point (2,4), this means x2 = 2 and y2 = 4
If we substitute those values into the slope formula you end up with this:
[tex]m = \frac{y2-y2}{x2-x1} = \frac{4 - (-1)}{2 - (-2)} = \frac{4+1}{2+2} =\frac{5}{4}[/tex]
Step 2: Substitute the values into the point-slope formula:
[tex]y - y1 = m(x- x1)[/tex]
Now that we know m = 5/4 , you can substitute this into the above formula and you get:
[tex]y - y1 = m(x- x1)[/tex]
[tex]y - (-1) = \frac{5}{4} (x - (-2)) \\y + 1 = \frac{5}{4} ( x + 2)[/tex]
[tex]y = \frac{5}{4}(x + 2) - 1[/tex]
The heaviest land animal ever recorded (according to the Guinness Book of World Records) was a male African bush elephant. He weighed 13.5 tons measured to the nearest half-ton. How would you find the elephant’s minimum and maximum possible weights?
Answer:
The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:
4 to the power of -1
Answer:
0.25
I hope this helps!
Answer:
1/4
Step-by-step explanation:
Negative exponents basically flip the number upside down,
so 4 ^ -2 would be 1/4^2
where the four has a power of 2.
The answer would therefore be 1/16
Numbers to the power of 1, is just the same number, so if you have negative exponents, it would be the same 4, except flipped over.
Una empresa comercial vende automóviles cuyo precio es de S/.60000, con una cuota inicial del 20 % , para cancelar el saldo en treinta meses de plazo . Calcula la cuota fija mensual que se pagara si la empresa cobra una tasa de interes simple del 12% semestralmente
Responder:
$ 2560
Explicación paso a paso:
Dado lo siguiente:
Importe total (A) = 60000
Pago inicial = 20% de A
Pago inicial = 0,2 * 60000 = 12000
Importe pendiente de pago = (60000 - 12000) = 48000
Calcular el interés simple sobre el saldo de 48000 = principal
principal * tasa * tiempo
(48 000 * 0,12 * (30/6))
48000 * 0,12 * 5 = 28800
Por tanto, el importe total a pagar durante 30 meses será:
(48 000 + 28800) = 76800
Dado que el pago mensual es fijo:
Pago mensual = (monto total a pagar / cantidad de meses)
Pago mensual = (76800/30)
Pago mensual = $ 2560

What is the y-intercept of 3x+5y=−30 ?
(0,−6)
(−6,0)
(10,−6)
(0,10)
Answer: (0,-6)
Step-by-step explanation:
To find the y-intercept, we can rewrite the equation into slope-intercept form.
3x+5y=-30 [subtract both sides by 3x]
5y=-3x-30 [divide both sides by 5]
y=-3/5x-6
Now that the equation is in slope-interceot form, we know that the y-intercept is -6, we know that the answer is (0,-6).

Answer:
I may be wrong here, but I think it's C If not then I have no idea ;-;
Step-by-step explanation:
Where is the mistake she made and explain why please help??????????????
The first mistake is that she went from 3x-2 to 3x+2. Everywhere you see "3x+2", change it to "3x-2".
Another mistake is we shouldn't use absolute value in this case. This is because we're dealing with an odd number index. In this case, the index of the root in the original equation is 3. Because there isn't any absolute value, we won't have a plus/minus.
So we should have 3x-2 = 8 for the third to last step. That solves to x = 10/3 as the only solution.
If Q(x) = 6x2 - 1, find Q(-7).
Answer:
[tex] \huge \boxed{Q( - 7) = 293}[/tex]
Step-by-step explanation:
[tex]Q(x) = {6x}^{2} - 1[/tex]
To find Q(-7) , insert the value of x that's - 7 into Q(x). That is for every x in Q(x) , replace it with - 7
We have
[tex]Q( - 7) = 6 ({ - 7})^{2} - 1 \\ = 6(49) - 1 \\ = 294 - 1[/tex]
We have the final answer as
[tex]Q( - 7) = 293[/tex]

A college has a financial aid formula that applies to applicants whose family's income is below a certain threshold. The financial aid can be determined by the function f(x)=25000+3000x,f(x)=25000+3000x, where xx is the number of siblings (including half siblings and step siblings) that the applicant has living in their household. Find and interpret the given function values and determine an appropriate domain for the function.
The values of the function are,
f (- 3) = 16,000 meaning a qualifying applicant with - 3 siblings in their household would get $16,000 in financial aid. This interpretation does not make sense in the context of the problem.
f (3) = 34,000 meaning a qualifying applicant with 3 siblings in their household would get $34,000 in financial aid. This interpretation makes sense in the context of the problem.
The domain for this function is x ≥ 0, indicating that the number of siblings must be a non-negative whole number or zero.
Given that,
The function is,
[tex]f (x) = 25000 + 3000x[/tex]
Where x is the number of siblings.
Hence, the values of the function are found as,
[tex]f (x) = 25000 + 3000x[/tex]
Put x = - 3;
[tex]f (- 3) = 25000 + 3000 \times - 3[/tex]
[tex]f (- 3) = 25000 - 9000[/tex]
[tex]f (- 3) = 16,000[/tex]
Put x = 3;
[tex]f (x) = 25000 + 3000x[/tex]
[tex]f (3) = 25000 + 3000 \times 3[/tex]
[tex]f ( 3) = 25000 + 9000[/tex]
[tex]f (3) = 34,000[/tex]
Since the given function is,'
[tex]f (x) = 25000 + 3000x[/tex]
Regarding the domain of the function,
Since the number of siblings (x) must be a non-negative integer, it represents the count of individuals.
Therefore, the appropriate domain for this function would be x ≥ 0, meaning x can be any non-negative whole number or zero.

Leo invested $1900 in an account with annually compounded interest. After 3 years, he had $2275 in the account. What was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign.
Answer:
6.2
Step-by-step explanation:
Use the formula for calculating compound interest PN=P0(1+rk)Nk where r is the unknown, PN=2275, P0=1900, k=1, and N=3. Substitute the values into the formula and simplify.
2275=1900(1+r1)3⋅1
Let's simplify within the parenthesis and the exponent.
2275=1900(1+r)3
Divide both sides by 1900.
22751900=(1+r)3
To isolate the variable, take the cube root of each side.
22751900−−−−−√3=1+r
Subtract 1 from each side to get r by itself.
22751900−−−−−√3−1=r
Simplify for an answer of r≈0.062 which is the interest rate 6.2%.

Supplementary angles are angles that sum up to 180 degrees
Step 1:
If m<x and m<y are supplementary, hence;
m<x + m<y = 180 ....................1
Step 2:
If m<y is a supplement to m<z, hence:
m<y + m<z = 180 ...........................2
Equating 1 and 2
m<x + m<y = m<y + m<z
Subtract m<y from both sides
m<x + m<y-m<y = m<y + m<z - m<y
m<x = m<z
This proves the statement m<x = m<z
