wuch equation represents O AB OB. re
Answer:
The answer that is C
Step-by-step explanation:
The equation would be y=1/2x + 8 because the line touches the y-intercept at +8. The others would be incorrect as the line does not increase by a slop of 8/1 and/or is the y-intercept at -8.
FILL IN THE BLANKS 1) 257x_____=(-257) 2)(-30)x_____=(-270) 3)_____x(-21)=_____ 4)918x_____=0 5)(-56)x[(-9)+(-1)]=_____
Answer:
[tex](a)\ 257 * [-1] =-257[/tex]
[tex](b)\ (-30) * [9] =-270[/tex]
(c) The additive inverse of -21 is 21
[tex](d)\ 918 *[0]=0[/tex]
[tex](e)\ (-56) * [(-9)+(-1)] = 560[/tex]
Step-by-step explanation:
Required
Fill in the blanks
Represent all blanks with x
[tex](a)\ 257 * x =-257[/tex]
Divide both sides by 257
[tex]x =\frac{-257}{257}[/tex]
[tex]x = -1[/tex]
So:
[tex](a)\ 257 * [-1] =-257[/tex]
[tex](b)\ (-30) * x =-270[/tex]
Divide both sides by -30
[tex]x =\frac{-270}{-30}[/tex]
[tex]x = 9[/tex]
So:
[tex](b)\ (-30) * [9] =-270[/tex]
(c)The complete question here is to determine the additive inverse of (-21)
The [tex]additive[/tex] [tex]inverse[/tex] of a [tex]number[/tex] x is -x
So:
[tex](-21) \to -(-21)[/tex]
[tex](-21) \to 21[/tex]
[tex](d)\ 918 *x=0[/tex]
Divide both sides by 918
[tex]x=\frac{0}{918}[/tex]
[tex]x = 0[/tex]
So:
[tex](d)\ 918 *[0]=0[/tex]
[tex](e)\ (-56) * [(-9)+(-1)] = x[/tex]
Solve the inner brackets
[tex](-56) * [-9-1] = x[/tex]
[tex](-56) * [-10] = x[/tex]
Multiply
[tex]560 = x[/tex]
So:
[tex](e)\ (-56) * [(-9)+(-1)] = 560[/tex]

Answer:
[tex]y = \tan(x + \frac{x^2}{2})[/tex]
Step-by-step explanation:
Poorly formatted question; The complete question requires that we prove that [tex]y=\tan(x+\frac{x\²}{2})[/tex]
When
[tex]\frac{dy}{dx} =1+xy\²+x+y\²[/tex] and [tex]y(0)=0[/tex]
We have:
[tex]\frac{dy}{dx} =1+xy\²+x+y\²[/tex]
Rewrite as:
[tex]\frac{dy}{dx} =1+x+xy\²+y\²[/tex]
Factorize
[tex]\frac{dy}{dx} = (1+x)+y\²(x+1)[/tex]
Rewrite as:
[tex]\frac{dy}{dx} = (1+x)+y\²(1+x)[/tex]
Factor out 1 + x
[tex]\frac{dy}{dx} = (1+y\²)(1+x)[/tex]
Multiply both sides by [tex]\frac{dx}{1 + y^2}[/tex]
[tex]\frac{dy}{1+y\²} = (1+x)dx[/tex]
Integrate both sides
[tex]\int \frac{dy}{1+y\²} = \int (1+x)dx[/tex]
Rewrite as:
[tex]\int \frac{1}{1+y\²} dy = \int (1+x)dx[/tex]
Integrate the left-hand side
[tex]\int \frac{1}{1+y\²} dy = \tan^{-1}y[/tex]
Integrate the right-hand side
[tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex]
[tex]y(0)=0[/tex] implies that: [tex](x,y) = (0,0)[/tex]
So:
[tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex] becomes
[tex]\tan^{-1}(0) = 0 + \frac{0^2}{2} + c[/tex]
This gives:
[tex]0 = 0 +0 + c[/tex]
[tex]0 =c[/tex]
[tex]c = 0[/tex]
The equation [tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex] becomes
[tex]\tan^{-1}y = x + \frac{x^2}{2} + 0[/tex]
[tex]\tan^{-1}y = x + \frac{x^2}{2}[/tex]
Take tan of both sides
[tex]y = \tan(x + \frac{x^2}{2})[/tex] --- Proved

Answer:
y = (-2) 2^(x+1)
Step-by-step explanation:
Whenever x increases from by 1, y decreases by doubling (the negative value), so the exponent is -2
When x = -1, y = -2.
So the exponential equation (NOT linear) is
y(x) = -2*2^(x+1)
Check:
y(-1) = -2*2^(-1+1) = -2*1 = -2
y(0) = -2*2^(1) = -2*2 = -4
...
y(2) = -2*2^(2+1) = -2*8 = -16
all good.

What are the measures of ∠a, ∠b, and ∠c?
Answer:
a should be 45
b should be 90
c should also be 45
Step-by-step explanation:
I know this because 180-135=45 for a
since c is also 45, beside c should be 135.
which means those angles are congruent.
since a triangle equals 180 degrees all together 180-45-45=90
so b is 90

Select all the numbers that are irrational
A) [tex]-\sqrt{5}[/tex]
D) [tex]\pi[/tex]
===========================================
Explanation:
Choices B and C are rational because we can simplify them to form a fraction of integers.
[tex]-\sqrt{49} = -7 = -\frac{7}{1}[/tex]
[tex]\sqrt{0} = 0 = \frac{0}{1}[/tex]
Any rational number is of the form P/Q where P,Q are integers and Q is nonzero.
So we can rule out choices B and C.
---------------
Choice A on the other hand cannot be written as a fraction of integers. The 5 isn't a perfect square, which makes [tex]-\sqrt{5}[/tex] irrational.
The same can be said about [tex]\pi[/tex] which is roughly equal to 3.14; the decimal digits go on forever without a known pattern.
Choice A and choice D are the two answers.
----------------
If we know the pattern of the decimal digits, then we can turn the decimal number into a fraction of integers
The number -0.777, where the 7s go on forever, converts to the fraction -7/9
That means we rule out choice E.
Mahak is measuring the maximum space inside a watering can. This is a measure of A weight. B capacity.
Answer:
B. capacity.
Step-by-step explanation:
In this scenario, Mahak is measuring the maximum space inside a watering can. Thus, this is a measure of capacity because it gives the exact information as to the quantity of water the watering can hold at any given time.
Basically, the capacity of a container is a measure of the volume of fluid or any other substance that it is able to hold, which is typically measured in litres or cubic centimeters.
For example, if the shape of the watering can is cylindrical; its capacity (volume) would be measured using a mathematical expression.
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.answer??? please answer
Answer:
∠ 1 = 94°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle, then
∠ 1 + 36° = 130° ( subtract 36° from both sides )
∠ 1 = 94°

Step-by-step explanation:
Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.
Which product should Tomas choose?
(2x + y)(2x2 + 2xy – y2)
(2x + y)(4x2 + 2xy – y2)
(2x + y)(4x2 – 2xy + y2)
(2x + y)(2x2 – 2xy + y2)

[tex]\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}[/tex]
[tex](a + b)( {a}^{2} - ab + {b}^{2} )[/tex]
Substituting the values of "a = 2x" and ''b = y" in the expression, we have
[tex](2x + y)[( 2{x})^{2} - 2xy + {y}^{2} ] \\ = (2x + y)(4 {x}^{2} - 2xy + {y}^{2} )[/tex]
[tex]\large\mathfrak{{\pmb{\underline{\orange{Happy\:learning }}{\orange{.}}}}}[/tex]
The product that Tomas should choose should be (2x +y)(4x^2 – 2xy + y^2)
Sum of the cube of valuesGiven the sum of cubes expressd as:
a^3 + b^3 = (a + b)(a^2 – ab + b^2)
Given the following parametrs
a = 2x
b = y
Substitute this values into the formula
a^3 + b^3 = (2x + y)((2x)^2 – 2xy + y^2)
a^3 + b^3 = (2x +y)(4x^2 – 2xy + y^2)
Hence the product that Tomas should choose should be (2x +y)(4x^2 – 2xy + y^2)

a movie theater sells up 10 tickets at a time online. What is the domain of this graph
Answer:
Whole numbers or integers from 0 to 10
Step-by-step explanation:
Either 0 tickets can be sold, or 1, or 2, or 3, or 4, etc. up to a maximum of 10;
It is not possible to sell -1 tickets or ¹/₂ a ticket and we are told they don't sell more than 10 so 11 is not a possibility either;
Logically then, the only possibilities are whole numbers between 0 and 10
How many solutions does y+x=5 5x+5y=25 have?
A) One
B) Infinitely Many
C) None
D) Two
Answer:
B is the answer.
Step-by-step explanation:
Given equations y + x = 5 and 5x + 5y = 25.
These equations have infinetely many solutions because they are equivalent.
This can be proven by the multiplicative property of equality and the commutative property of addition.
y + x = 5 → y × 5 + x × 5 = 5 × 5 [multiplicative property of equality] → 5y + 5x = 25 → [commutative property of addition] 5x + 5y = 25.
