Evaluate -2 x 2y , if x = -3 and y = -1.

Answer:

the answer is 25

Step-by-step explanation:

After simplifying the expression the final value of the expression is given by 25

Exponent is a mathematical operation, written as an. Here the expression an involves two numbers, the base 'a and the exponent or power 'n'. Exponents are used to simplify algebraic expressions.

Given here : The expression 5⁸×5⁻² / 5⁴

We know from the law of exponents, for any non-zero term a,

[tex]a^m.a^n=a^{m+n}[/tex]

Thus simplifying the expression we get

5⁸×5⁻² / 5⁴

=5⁸⁻² /5⁴

=5⁶⁻⁴

=5²

=25

Hence, The value of the expression is 25

Explanation:

3(-1) - 10(-1) + 5 = 5(-1) + 17

-3 + 10 + 5 = -5 + 17

(add first before subtracting!)

12 = 12

Answer:

Hi, I'm unsure as to what digit you wanted us to round the answer to, so I rounded the answer to the 4 most commonly used decimal places.

First off, we figure out that 614 divided by 31 equals 19.8064516129.

Rounded to the nearest thousandth, that's 19.806.

Rounded to the nearest hundredth, that's 19.81.

Rounded to the nearest tenth, that's 19.8.

Rounded to the nearest whole number, that's 20.

Answer:

(9, 1)

Step-by-step explanation:

Given the coordinate of one corner of the house has been drawn at (6, 3), if the drawing is translated two units down and three units to the right

two units down = -2 (along the negative y axis)

three units to the right = +3 (towards the positive x-axis)

The coordinate used to translate the model of the house (x, y) is (3, -2)

Adding both coordinates:

= (x, y) + (6, 3)

= (x+6, y+3)

Substitute the values of the translated coordinates

= (3+6, -2+3)

= (9, 1)

The translation should be written as (3+6, -2+3) which is equivalent to (9, 1)

Step-by-step explanation:

x−7(x−2)=10x+9−x

Step 1: Simplify both sides of the equation.

x−7(x−2)=10x+9−x

x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)

x+−7x+14=10x+9+−x

(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)

−6x+14=9x+9

−6x+14=9x+9

Step 2: Subtract 9x from both sides.

−6x+14−9x=9x+9−9x

−15x+14=9

Step 3: Subtract 14 from both sides.

−15x+14−14=9−14

−15x=−5

Step 4: Divide both sides by -15.

−15x−15=−5−15

x=13

Answer:

[tex]\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]

Step-by-step explanation:

Given the expression  [tex]y^4+5x=11y[/tex], we are to find the second derivative [tex]\frac{d^2y}{dx^2}[/tex]

This differentiation will be implicit (indirect) as shown:

[tex]4y^3 \frac{dy}{dx} + 5 = 11\frac{dy}{dx} \\4y^3 \frac{dy}{dx} - 11 \frac{dy}{dx} = -5\\\frac{dy}{dx}(4y^3-11) = -5\\\frac{dy}{dx} = \frac{-5}{4y^3-11}[/tex]

Differentiating the second time using quotient rule:

[tex]\frac{d^2y}{dx^2} = \frac{4y^3-11 (0)- (-5)12y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2(\frac{-5}{4y^3-11} ) }{(4y^3-11)^2}\\\\\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]

Answer:

3 million or 3 x 10^6

Step-by-step explanation:

You would round this up to three million because the digit before it is 5 or larger. Then, using the three million number, you move the decimal over 6 places to get a digit less than ten so it would become 3 times 10 to the power of 6

Answer:

x-intercept is (-9,0)

y-intercpt is (0,27)

Step-by-step explanation:

you have to subsitute x and y from zero then you go from there

Answer:

Y-intercept (0,27)

X- intercept (-9,0)

Step-by-step explanation:

To find X - intercept, substitute in 0 for y and solve for X. To find Y-intercept, substitute in 0 for x and solve for y.

Y= 3x plus 27                                            

Y = 3(0) plus 27

Y = 0 plus 27

Y = 27                 The Y-intercept (0,27)

Y = 3x plus 27

0 = 3x plus 27

0 - 27 = 3x

-27 = 3x

divide by boyh side to 3 and X will be -9
