Answer:

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

4(3x + 3) = 15x + 7 - 3x + 5

Step 2: Solve for x

Here, we can see that x would be infinite amount of solutions. We can plug in any number x and it would render the equation true.

Both representations are equivalent and describe the same function.the function rule for this table is:   f(x) = -1/2 x 2

The slope or gradient of a line is a number that describes both the direction and the steepness of the line. A slope of a line is the change in y coordinate with respect to the change in x coordinate.

To write a function rule for a given array, we need to determine how the values ​​in the output column (y) relate to the values ​​in the input column (x).

Looking at the given data, we notice that the output values ​​decrease by 1 every time the input value increases by 2. This suggests that the function is linear and that we can use the slope-intercept form of a linear equation to represent it. .

The slope-intercept form of a linear equation is y = mx b, where m is the slope and b is the y-intercept. In this case, the slope m is -1/2 because the output values ​​decrease by 1 every time the input values ​​increase by 2. The y-intercept b is 2 because the output value is 2 when the input value is 0.

Therefore, the function rule for this table is:

f(x) = -1/2 x 2

where x is the input value and f(x) is the output value.

Alternatively, we can also represent the function in table entries, for example:

f(0) = 2

f(2) = 1

f(4) = 0

f(6) = -1

Both representations are equivalent and describe the same function.

Answer:

\(-\dfrac{1}{25}\)

Step-by-step explanation:

Given the rhombus CDEF, sides FC and CD are adjacent sides.

Using coordinate geometry, to proof that a quadrilateral is a square, with regards to the slope, the slope of adjacent segments must be negative reciprocals.

In fact, by definition: Two lines with slopes \(m_1$ and m_2\) are perpendicular if:

\(m_1=-\dfrac{1}{m_2}\)

Therefore if :

For the rhombus to be a square:

Slope of CD \(=-\dfrac{1}{25}\)

t = (6 + 3k)/(k - 2) is the formula for t in the equation k=2(t+3)/t-3.

The given equation is k=2(t+3)/t-3.

We need to isolate t on one side of the equation.

Let's start by cross-multiplying:

k(t - 3) = 2(t + 3)

Expanding the brackets:

kt - 3k = 2t + 6

Now, let's gather all the terms with t on one side and all the constant

terms on the other side:

kt - 2t = 6 + 3k

Factoring out t on the left side:

t(k - 2) = 6 + 3k

Finally, we can solve for t by dividing both sides of the equation by (k - 2):

t = (6 + 3k)/(k - 2)

Therefore, t is the subject of the formula, and it is given by t = (6 + 3k)/(k - 2).

she used = 3 over 18 m = 54 m²

left = 9 m²

maximum number of squares she could form of 1 m = 9

- x² < - 1

=》x² < 1

Now, let's check with x = 1

x² < 1

(1)² < 1

1 < 1

1 is not less than or greater than 1. They are equals. So, the inequality 5 - x² < 4 is NOT true for x = 1.

Answer:

use the tangent function to set up an equation:

tan(70°) = h/100

We can then solve for h by multiplying both sides by 100 and taking the tangent of 70 degrees:

h = 100*tan(70°)

Using a calculator, we get:

h ≈ 315.96 feet

the height of the tower is approximately 315.96 feet.

\( \frac{4}{3y} = 48 \\ \)

Inverse both sides

\( \frac{3y}{4} = \frac{1}{48} \\ \)

Multiply both sides by 4

\(4 \times \frac{3y}{4} = 4 \times \frac{1}{48} \\ \)

\(3y = \frac{4}{48} \\ \)

\(3y = \frac{4 \times 1}{4 \times 12} \\ \)

\(3y = \frac{1}{12} \\ \)

Divide both sides by 3

\(3y \div 3 = \frac{1}{12} \div 3 \\ \)

\(y = \frac{1}{12} \times \frac{1}{3} \\ \)

\(y = \frac{1}{36} \\ \)

_____________________________________________

\( \frac{4}{3} y = 48 \\ \)

Multiply both sides by the 3

\( 3 \times \frac{4}{3} y = 3 \times 48 \\ \)

\(4y = 3 \times 48\)

Divide both sides by 4

\(4y \div 4 = 3 \times 48 \div 4\)

\(y = \frac{48 \times 3}{4} \\ \)

\(y = \frac{4 \times 12 \times 3}{4 \times 1} \\ \)

\(y = 12 \times 3\)

Find x

The relationship between x, 47 and \(17^{\circ}\) is:

\(sin(17^{\circ}) = \frac{x}{47}\)

i.e.

\(sin(\theta) = \frac{Opposite}{Hypotenuse}\)

Solving further:

\(sin(17^{\circ}) = \frac{x}{47}\)

Make x the subject

\(x = 47 * sin(17^{\circ})\)

\(x = 47 * 0.2924\)

\(x =13.7428\)

By proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.

Given:

- Triangle ΔAEB and ΔDFC

- Line ABCD is straight (implies AC and BD are collinear)

- AE is parallel to DF

- EB is parallel to FC

- AC = DB

To prove: ΔEAB ≅ ΔFDC

Recall that:

AE || DF

EB || FC

AC = DB

AE || DF, EB || FC (Parallel lines with transversal line AB)

Corresponding angles are congruent:

  ∠AEB = ∠DFC (Corresponding angles)

  ∠EAB = ∠FDC (Corresponding angles)

Corresponding sides are proportional:

  AE/DF = EB/FC (Corresponding sides)

  AC/DB = BC/DC (Corresponding sides)

  AC = DB

  BC = DC (Equal ratios)

ΔEAB ≅ ΔFDC (By angle-side-angle (ASA) congruence)

∠EAB = ∠FDC

∠AEB = ∠DFC

AC = DB, BC = DC

Therefore, by proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.
