If you subtract 17 from my number and multiply the difference by −2​, the result is −8​." What is Elise​'s ​number?

Answer: Below

Step-by-step explanation:

General concept is that when you divide two fractions, the fraction becomes a reciprocal, and the division sign turns into multiplication. Using this handy cheat, we do:
-5 ÷ 2/7

-5 × 7/2

-35/2

This is our answer.

The true equation for this situation is given as JK/IK = MK/LK

Two figures are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.

Both triangles IJK and triangle KLM are similar triangles. Hence:

JK/IK = MK/LK

Answer:

[tex]\huge\boxed{\boxed{-46}}[/tex]

Step-by-step explanation:

Hello.

In order to solve this, we need to plug in the values of the variables:

p(-4)³+2(9)

(-4)³ is equal to -64, and 2 times 9 is 18:

-64+18

Add:

-46

And we're done!

using simultaneous equation:

2x + 3y = 190

3x + y = 180  * 3

Then:

2x + 3y = 190

9x + 3y = 540

--------------------

-7x = -350

x = 50

Insert this in equation 1 to find value of y:

2x + 3y = 190

2(50) + 3y = 190

3y = 190 - 100

3y = 90

y = 30

expanding the following:

→ (x + 2)³

[tex]\sf apply \ cubic \ formula : \bold{\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3}[/tex]

[tex]\rightarrow \sf x^3+3x^2\cdot \:2+3x\cdot \:2^2+2^3[/tex]

[tex]\rightarrow \sf x^3+6x^2+12x+8[/tex]

Justify for x = 5

[tex]\rightarrow \sf (5)^3+6(5)^2+12(5)+8[/tex]

[tex]\rightarrow \sf 125+150+60+8[/tex]

[tex]\rightarrow \sf 343[/tex]

Answer:

Step-by-step explanation for (a):

First use system of equations. Isolate a variable and substitute.

2x + 3y = 190

3x + y = 180

Isolate

subtract 3x from both sides of the second equation

y = 180 - 3x

since 180 - 3x = y, you can substitute this into the first equation for y

Substitute

2x + 3y = 190

2x + 3(180 - 3x) = 190

Distribute the 3

2x + (540 - 9x) = 190

Solve for x

subtract 540 from both sides

2x - 9x = -350

simplify

-7x = -350

divide each side by -7

x = 50

But you still need to solve for y, so substitute the x back into the first equation.(But really you could use either equation)

2(50) + 3y = 190

subtract 100 (2 * 50) from both sides

3y = 90

y = 30

Check your work by resubstituting.

3(50) + 30 = 180.

(b) This one is weird.

(Remember, it is NOT (x^3 + 8), you don't "distribute" the exponent)

It then simplifies to x^3 + 6x^2 + 12x + 8, and x = 5 is NOT an answer here. Maybe there is something more that you might not have screenshotted?

*edit its not asking to prove x is a solution(which i thought lolllll) its asking to plug x = 5 into the equation*

Answer:

y = 128(4.926)^x

Step-by-step explanation:

Exponential function: y = ab^x

x = 0, y = 128

128 = ab^0

128 = a

--------------------

a = 128, y = 371,293, x = 5

371,293 = 128 x b^5

b^5 = ( 371,293 / 128 )

b = (fifth root) 5^√2900.7265625

b ≈ 4.926

----------------------------------------

y = 128(4.926)^x

I hope this helps!

Hi!

In any quadratic in the form you have given ([tex]ax^2+bx+c=0[/tex]), the discriminant is ALWAYS

[tex]b^2-4ac[/tex]

Given the quadratic formula:

[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]

-------------------------------------------------------------------------------------------------------------

The discriminant would be the part of the equation that is under the square root.

-------------------------------------------------------------------------------------------------------------

Therefore, your answer is [tex]b^2-4ac[/tex]

Answer:

20 years

Step-by-step explanation:

let the present age of father=x

[tex]\frac{x}{15} =\frac{10}{3} \\x=\frac{10}{3} \times 15=50 \\[/tex]

present age of father=50 years

let after y years ages are in the ratio 2:1

[tex]\frac{50+y}{15+y} =\frac{2}{1}[/tex]

50+y=2(15+y)

50+y=30+2y

50-30=2y-y

Answer:

Parallel line: [tex]y=4x+33[/tex]

Perpendicular line: y = [tex]\frac{-1}{4}x-1[/tex]

Step-by-step explanation:

From the given equation [tex]y=4x-2[/tex], the number multiplied by [tex]x[/tex] is the slope of that equation, so the slope is 4 in this case.

Let's use the point slope form in this question:

[tex]{y-y__1}=m({x-x__1})[/tex]

where [tex]{x__1}[/tex] and [tex]y__1[/tex] are the given points in your question:

[tex]{x__1}=-8[/tex]

[tex]{y__1} = 1[/tex]

and m is the slope.

Parallel line:

Since parallel means the same slope as the given equation, we put [tex]m = 4[/tex] first.

[tex]{y-1}=4({x-(-8)})[/tex]

[tex]y=4x+33[/tex]

This is the equation that is parallel to [tex]y=4x-2[/tex] and also passes through [tex](-8,1)[/tex].

Perpendicular line:

Since perpendicular means exactly 90° with the given equation, multiplying their slopes and the product will always be [tex]-1[/tex].

Let's find m first,

[tex]4* m = -1[/tex]

[tex]m = \frac{-1}{4}[/tex]

Now using the same point slope form with the same [tex]x__1[/tex] and [tex]y__1[/tex]:

[tex]{y-y__1}=m({x-x__1})[/tex]

[tex]{y-1}=\frac{-1}{4} ({x-(-8)})[/tex]

[tex]y=\frac{-1}{4}x-1[/tex]

This is the equation that is perpendicular to [tex]y=4x-2[/tex] and also passes through [tex](-8,1)[/tex].

Answer:

h=m+43, 66cm

Step-by-step explanation:

For each month, it grows by one centimeter, which is represented by 1m or just m. You also have to add the height it already has, which makes h=m+43. For 21 months, substitute 21 for m to get h=21+43 which simplifies into h=66 cm

The formula that can be used to determine the future value of an amount with compounding is:

FV = P (1 + r)^nm

Where:

Future value with monthly compounding = $2000 x ( 1 + 0.035/12)^(12 x 8) = $2645.18

Future value with continuous compounding =  : A x e^r x N

1000 x e^0.018 x 8 = $8,145.30

Total = $8,145.30 + $2645.18 = $10,790.48

Future value with quarterly compounding = 2500 x (1 + 0.012 / 4)^(4 x 8) = $2,751.50

Future value with quarterly compounding = 500 (1 .0225)^(8x4) = $1019.05

Total = $3,770.55

$3000 x e^0.032 x 8 = $24,780.42

Future value with exponential increase = 1050 x (1.015)^8 = $1,182.82

Future value with biannual compounding = 1950 x (1 + 0.028/2)^(8 x 2) = $2435.80
