Refer to the given expression: - 6x + 9 - 12 + 8x + x
a) How many terms are in the expression?
b) Identify the variable.
c) Identify the coefficients.
d) Identify the constants.
e) Simplify the expression above.​

If she has increased by 75% in a week to get 14000 points then  we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

175% * x = 14000

1.75x =14000     Divide both sides by 1.75

x= 8000

So she had 8000 points last week.

Check:

175% * 8000= 14000

1.75 * 8000 = 14000

  14000 = 14000

Answer:

8,000 points

Step-by-step explanation:

x + 0.75x = 14,000 (the initial amount of points X plus 0.75x)

1.75x = 14000

x = 14000/1.75

x = 8,000

Answer:

Area: AB × AD × sin 74= 8.9×6.7×24/25= 57.244 cm^2

Step-by-step explanation:

[tex]\mathsf{Given :\;\dfrac{{sec}^2\theta - co{sec}^2\theta}{{sec}^2\theta + co{sec}^2\theta}}[/tex]

[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{{sec}\theta = \dfrac{1}{cos\theta}}}}[/tex]

[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{co{sec}\theta = \dfrac{1}{sin\theta}}}}[/tex]

[tex]\mathsf{\implies \dfrac{\dfrac{1}{cos^2\theta} - \dfrac{1}{sin^2\theta}}{\dfrac{1}{cos^2\theta} + \dfrac{1}{sin^2\theta}}}[/tex]

[tex]\mathsf{\implies \dfrac{\dfrac{sin^2\theta - cos^2\theta}{sin^2\theta.cos^2\theta}}{\dfrac{sin^2\theta + cos^2\theta}{sin^2\theta.cos^2\theta}}}[/tex]

[tex]\mathsf{\implies \dfrac{sin^2\theta - cos^2\theta}{sin^2\theta + cos^2\theta}}[/tex]

Taking sin²θ common in both numerator & denominator, We get :

[tex]\mathsf{\implies \dfrac{sin^2\theta\left(1 - \dfrac{cos^2\theta}{sin^2\theta}\right)}{sin^2\theta\left(1 + \dfrac{cos^2\theta}{sin^2\theta}\right)}}[/tex]

[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{cot\theta = \dfrac{cos\theta}{sin\theta}}}}[/tex]

[tex]\mathsf{\implies \dfrac{1 -cot^2\theta}{1 + cot^2\theta}}[/tex]

[tex]\mathsf{Given :\;cot\theta = \dfrac{1}{\sqrt{5}}}[/tex]

[tex]\mathsf{\implies \dfrac{1 - \left(\dfrac{1}{\sqrt{5}}\right)^2}{1 + \left(\dfrac{1}{\sqrt{5}}\right)^2}}[/tex]

[tex]\mathsf{\implies \dfrac{1 - \dfrac{1}{5}}{1 + \dfrac{1}{5}}}[/tex]

[tex]\mathsf{\implies \dfrac{\dfrac{5 - 1}{5}}{\dfrac{5 + 1}{5}}}[/tex]

[tex]\mathsf{\implies \dfrac{5 - 1}{5 + 1}}[/tex]

[tex]\mathsf{\implies \dfrac{4}{6}}[/tex]

[tex]\mathsf{\implies \dfrac{2}{3}}[/tex]

Hence, option (a) 2/3 is your correct answer.

The composition of function f ( x ) / g ( x ) = -x² + x - 1

Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

Given data ,

Let the first function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x⁴ - x³ + x²

Let the second function be represented as g ( x )

Now , the value of g ( x ) is

g ( x ) = -x²

Now , the composition of function is ( f/g ) ( x )

On simplifying , we get

( f/g ) ( x ) = f ( x ) / g ( x )

f ( x ) / g ( x ) = x⁴ - x³ + x² / -x²

f ( x ) / g ( x ) = -x² + x - 1

Hence , the function is A = -x² + x - 1

Answer:

y = -1x - 2/2

Step-by-step explanation:

Slope is -1

B = 2/-2

Answer:

y = x - 4

Step-by-Step Explanation:

Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.

Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1  (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).

Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):

y = mx + b

-2 = 1(2) + b

-2 = 2 + b

Subtract 2 from both sides to solve for b:

-2 - 2 = 2 - 2 + b

-4 = b

Therefore, the y-intercept (b) = -4.

Hence, the equation of the perpendicular line is: y = x - 4

The answer is 12x - 17.

Step-by-step explanation:

Answer:

y = 2x + 5

Step-by-step explanation:

Finding the slope:

[tex]\frac{y2-y1}{x2-x1}\\[/tex]

= (1-(-3))/(-2-(-4))

= (1+3)/(-2+4)

= 4/2

= 2

Slope: 2

Substituting the slope into the formula 'y=mx+c':

y = 2x+c

Substituting any point (in this case, (-2,1)):

1 = 2(-2) + c

1 = -4 + c

c = 1 + 4

c = 5

Hence,

y = 2x + 5
