Simply this expression: -2+3-(5-6x)
Answer:
6x-4
Step-by-step explanation:
Answer:
-4-6x
Step-by-step explanation:
you would just combine -2 and 3 so you get 1 and then you would get 1-(5-6x) and you can just take away the parenthesis since in this case it doesn't matter and when you simplify that you get -4-6x

A ball is thrown starting at a time of O and a height of 2 meters. The height of the ball follows the function
H(t)= -4.9t^2 +25t +2. What is the height of the ball at each second from 0 to 5?
Answer:
0 - 1 - 2 - 3 - 4 - 5
2 - 22.1 - 32.4 - 32.9 - 23.6 - 4.5
Step-by-step explanation:
The function is:
H(t) = -4.9t^2 +25t +2Calculating the value of H for each value of t from 0 to 5
H(0) = 2H(1) = -4.9*1^2 + 25*1 + 2 = 22.1H(2) = - 4.9*2^2 + 25*2 + 2 = 32.4H(3) = -4.9*3^2 + 25*3 + 2 = 32.9h(4) = -4.9*4^2 + 25*4 + 2 = 23.6H(5) = - 4.9*5^2 + 25*5 + 2 = 4.5Correct answer choice is the 3rd one or C

3(x+14)=42 plz need help now
Answer:
0
Step-by-step explanation:
So we have the equation:
[tex]3(x+14)=42[/tex]
Divide both sides by 3:
[tex]x+14=14[/tex]
Subtract 14:
[tex]x=0[/tex]
The value of x is 0
Answer: x=0
Step-by-step explanation:
Given
3(x+14)=42
Distributive property
3x+42=42
Subtract 42 from both sides
3x=0
Divide 3 on both sides
x=0
----------------------------------------------------
Given
3(x+14)=42
Divide 3 on both sides
x+14=14
Subtract 14 on both sides
x=0
Both ways are fine
Hope this helps!! :)
Identify the roots of the equation x^2 = 9x − 14 by factoring. x = 2 or x = 7 x = −2 or x = 7 x = 2 or x = −7 x = −2 or x = −7
Answer:
x = 7, x = 2
Step-by-step explanation:
Given
x² = 9x - 14 ( subtract 9x - 14 from both sides )
x² - 9x + 14 = 0 ← in standard form
(x - 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and splve for x
x - 7 = 0 ⇒ x = 7
x - 2 = 0 ⇒ x = 2

what is half the sum of x and y decreased by one-third y as a algebraic expression
Answer:
1/2(x+y) - 1/3
Step-by-step explanation:
I think this may be the answer based on the info you've given
Answer:
[tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex]
Step-by-step explanation:
We can translate these words into an expression by just reading them and interpreting them.
Half the sum of x and y.
We know that it's going to include [tex](x+y)[/tex], and if we're taking half of that, we multiply that by [tex]\frac{1}{2}[/tex], so [tex]\frac{1}{2}(x+y)[/tex]
We also know that one third of y will be multiplying y by [tex]\frac{1}{3}[/tex], so [tex]\frac{1}{3}y[/tex].
Since we are decreasing [tex]\frac{1}{2}(x+y)[/tex] by [tex]\frac{1}{3}y[/tex], there's a minus sign between the terms.
So, [tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex].

The original price of a toy was $400. It was increased by 20%. after some time the sale of toys decreased. So, the shop owner decided to decrease the price by 20%
What is the final price of the toy.
Answer:
$384
Step-by-step explanation:
Original price = $ 400
Increased price = 20% of 400
= [tex]\frac{20}{100}[/tex] * 400
= $ 80
Price after increase = 400 + 80 = $ 480
Decreased price = 20% of 480
= [tex]\frac{20}{100}\\[/tex] * 480
= $ 96
Price after decreasing 20% = 480 - 96 = $ 384
Final price of the toy = $ 384
How much will it take to do a work of 190J with 15w power
Answer:
[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]
Step-by-step explanation:
[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]
[tex]\displaystyle P= \frac{W}{t}[/tex]
[tex]\displaystyle 15= \frac{190}{t}[/tex]
Solve for t.
Multiply both sides by t.
[tex]15t =190[/tex]
Divide both sides by 15.
[tex]\displaystyle t= \frac{190}{15}[/tex]
[tex]t \approx 12.67[/tex]
[tex] \bf \underline{ \underline{given : }}[/tex]
Work = 190 JPower = 15 W[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]
Calculate the time ?
[tex]\bf \underline{ \underline{
Formula \: applied :}}[/tex]
[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]
[tex]\bf \underline{ \underline{Solution : }}[/tex]
We know,
[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]
[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]
Substituting the values of work and power, we get:
[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]
[tex] \sf\implies{Time = 12.66 \: s}[/tex]
Thus,the time taken by a body is 12.66 seconds.

evaluate the expression
Answer: 85
Step-by-step explanation:
To solve this problem, we want to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.
------------------------------------------------------------------------------------------------------------
20÷(5-3)+5²(3) [solve parenthesis]
20÷(2)+5²(3) [solve exponent]
20÷2+25(3) [solve multiply or divide, left to right]
10+75 [solve add or subtract]
85
Answer:
85
Step-by-step explanation:
To evaluate the expression, follow the rule of PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
[tex]20 \div (5-3) +5^2(3)[/tex]
Solve inside the parentheses first by subtracting 3 from 5.
5-3 = 2
[tex]20 \div (2) +5^2(3)[/tex]
Next, evaluate the exponent.
5² = 5*5= 25
[tex]20 \div 2+25(3)[/tex]
Next, multiply 25 and 3.
25 *3 =75
[tex]20 \div 2+75[/tex]
Then, divide 20 by 2.
20/2=10
[tex]10+75[/tex]
Finally, add 10 and 75.
[tex]85[/tex]
The expression [tex]20 \div (5-3) +5^2(3)[/tex] evaluated is 85.

45% of the pizzas in the freezer in the store are cheese pizzas. There are 120 pizzas in the
freezer. How many of them are cheese pizzas?
Answer:
54 cheese pizzas
Step-by-step explanation:
We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.
We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.
45% * 120
Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.
45/100= 0.45 or 45.0 --> 4.5 ---> 0.45
0.45 * 120
Multiply 0.45 and 120
54
54 cheese pizzas are in the freezer.
This diagram is a straightedge and compass construction. A is the center of one circle, and B
is the center of the other. Select all the true statements.
a. AC = BC
b. AC = BD
C. CD = AB
d. ABCD is a square
e. ABD is an equilateral triangle
f. CD = AB + AB
Answer:
Correct choices are a, b, e
Step-by-step explanation:
As per diagram, the circles are equal.
Since the distance AB is the radius of both circles:
AB = AC = BC = BD = AD = rSo the answer choices:
a. AC = BC
Correct, both equal to rb. AC = BD
Correct, both equal to rC. CD = AB
Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3d. ABCD is a square
Incorrect. ACBD is rhombuse. ABD is an equilateral triangle
Correct, all three sides are equal to rf. CD = AB + AB
Incorrect as CD = AB√3N=1500(2^018t), t≥0 Find the initial number of cells (N) in the culture, given the exponential function.
Answer:
1500
Step-by-step explanation:
Step 1: Understand what the question is asking you
It wants to know how much cells do you start off with or in other words how much cells are in the culture when time is 0
Step 2: Set t = 0
[tex]N = 1500(2^{0.18(0)} )[/tex]
Step 3: Solve for N
[tex]N = 1500(2^{0.18(0)} )[/tex]
[tex]N = 1500(2^{0} )[/tex]
[tex]N = 1500(1 )[/tex]
[tex]N = 1500[/tex]
Therefore when the initial amount of cells there in the culture is 1500

Answer:
30
Step-by-step explanation:
2/3 = .6
18/.6 = 30
Answer:
27
Step-by-step explanation:
If you want to divide a fraction, you have to divide it from it's reciprocal.
The reciprocal of 2/3 is 3/2.
Now, you have to multiply 3 and 18
18 x 3/2 = 54/2
54 divided by 2 is 27.

Give an example of a set of ordered pairs that has five elements in its domain and four elements in its range.
Answer:
[ (-1,0) (0,0) (1,1) (2,2) (3,3) ]
Domain = { -1,0,1,2,3 }; Range = { 0,1,2,3 }
Step-by-step explanation:
Set or collection of ordered pairs is called 'Relation'. The ordered pairs are in terms f x & y coordinate.
Eg : [ (-1,0) (0,0) (1,1) (2,2) (3,3) ]
Domain is a set of all x axis values. Range is a set of all y axis values. They are arranged non repetitively in ascending order.
Domain = { -1,0,1,2,3 }
Range = { 0,1,2,3 }
As mentioned : the relation has been designed, as such to have five elements in its domain and four elements in its range
