We can use the distance formula to determine the side lengths of DEF.

D (3, -1)

E (7, -4)

F (4, -4)

DE --> √((7 - 3)^2 + (-4 - (-1))^2) = √(4^2 + (-3)^2) = √(16 + 9) = √25 = 5

DF --> √((4 - 3)^2 + (-4 - (-1))^2) = √(1^2 + (-3)^2) = √(1 + 9) = √10 ≈ 3.2

EF --> √((7 - 4)^2 + (-4 - (-4)^2) = √(3^2 + 0^2) = √9 = 3

Notice DEF is congruent to ABC because due to SSS (side-side-side) congruency; DE = AB, DF = AC, EF = BC. Because DEF and ABC are congruent, DEF and ABC must have congruent angles.

angleBAC = angleEDF = 34.7 degrees

angleACB = angleDFE = 108.4 degrees

angleCBA = angleFED = 36.9 degrees

The amplitude, midline and period of the function are 3 units, 4units and 5 units respectively

The amplitude is half the full height of the periodic function. That is:

Amplitude = (maximum - minimum)/2

Check the image attached, the maximum and minimum are labeled max and min respectively

Amplitude = (-1 - (-7))/2  = 6/2 = 3 units

The midline is the middle of the periodic graph or halfway between the minimum and maximum of the graph

Midline = (maximum + minimum)/2

Midline = (-1 + (-7))/2 = -8/2 = -4 units

The period is the distance between two peaks or (maximums) on the graph.

Period = 1-(-4) = 5 units

Therefore, the amplitude, midline and period are 3 units, 4units and 5 units respectively

The equation of line passes through the point (-4, -2) will be;

⇒ 3x - 4y = - 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, -2).

And, The parallel line is,

⇒ 3x - 4y = 7

⇒ y = 3/4x - 7/4

Now,

Since, The equation of line passes through the point (- 4, -2).

So, We need to find the slope of the line.

Since, The slope of the parallel line is same.

Hence, Slope of the line is,

⇒ y = 3/4x - 7/4

m = dy/dx = 3/4

m = 3/4

Thus, The equation of line with slope 3/4 is,

⇒ y - (-2) = 3/4 (x - (-4))

⇒ y + 2 = 3/4 (x + 4)

⇒ y + 2 = 3/4x + 3

⇒ y = 3/4x + 3 - 2

⇒ y = 3/4x + 1

⇒ 4y = 3x + 4

⇒ 3x - 4y = - 4

Therefore, The equation of line passes through the point (-4, -2) will be;

⇒ 3x - 4y = - 4

T is the midpoint of RS and V lies between Rand T is RV+VT =TS

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.

Divide the measurement of the distance between the two end locations by 2. The middle of that line is located at this separation from either end. Alternately, combine the two endpoint x coordinates and divide by 2. similarly for the y coordinates.

Answer:

You do it as solving by substitution.So first make x the subject of the formula in eqn1

substitute eqn1 into eqn two and solve After getting y substitute in the equation* and get x

The value of x and y in the system of equations are 8 and -5 respectively.

Given,

2x + 5y = -9

3x + 4y = 4

Now,

To solve the system of equation,

Let us make the coefficient of x same in both the equations to eliminate x.

2x +5y = -9

3x + 4y = 4

Multiply equation 1 with 3 and equation 2 with 2.

6x + 15y = -27

6x + 8y = 8

Now subtract both the equations,

7y = -35

y = -5

Now substitute y in equation,

2x + 5(-5) = -9

2x - 25 = -9

x = 8

Thus the system of equation solutions are x = 8 and y = -5.

The zeros of the function algebraically, by using these values we get, {x = -3/5,  x = 3/5}

What are the zeros of the function algebraically?

The zeros of a function are the points at which the function's value is zero. These are obtained algebraically by setting the function to zero and solving the quadratic.

We have,

f(x) = -25x⁴ + 9x²

= (25 • (x⁴)) -  32x²

= (5)²x⁴ -  (3)²x²

= 25x⁴ - 9x²

= x² • (25x²- 9)

25x² - 9

  A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

25  is the square of  5

9 is the square of 3

x²  is the square of  x¹

Factorization is  (5x + 3)  •  (5x - 3)

x² * (5x+3) * (5x-3)

Answer: x = 85° ,   y =45°

Step-by-step explanation:

x + 95 = 180°

x = 180° - 95°

x = 85°

In a triangle,

50° + x + y = 180°

50° + 85° + y = 180°

135° + y = 180°

y = 45°

From the above given expression

x = 35°

y = 95°

In a straight line, the angle is 180°

given angles are  50° internal angle and 95° external angle

then   x + 50° + 95° = 180°

          x + 145° =  180°

          x = 180° - 145°

          x = 35°

so in a triangle total angle is 180°

then  50° + x + y = 180°

         50° + 35° + y 180°

         y = 180° - 85°

The correct solution is x=(+11 , +3)

Step-by-step solution:

2(x-7)²=32

⇒2(x-7)(x-7)=32

⇒(x-7)(x-7)=(32/2)

⇒(x-7)(x-7)=16

⇒(x-7)²=16

⇒[tex](x-7)=\sqrt{16}[/tex]

⇒(x-7) = ±4

⇒(x-7) = +4   or   ⇒(x-7) = -4

⇒x = +4+7   or   ⇒x = -4+7

⇒x = +11  or   ⇒x = +3

Therefore, the correct solution is x = (+11 , +3)

The solution to each of the equations are matched together as:

1. 4 = 6/a*x + 5 → x = -a/6

2. 7 + 2ax = 13 → x = 3/a

3. -ax - 20 = -14 → x = -6/a

To solve an equation, apply the properties of equality in order to isolate the variable solved for to one side of the equation, which gives us the solution to the problem.

1. 4 = 6/a*x + 5

4 = 6x/a + 5

Combine like terms

-6x/a = -4 + 5

-6x/a = 1

-6x/a(a) = 1(a) [multiplication property of equality]

-6x = a

-6x/-6 = a/-6 [division property of equality]

x = -a/6

2. 7 + 2ax = 13

2ax = 13 - 7

2ax = 6

Divide both sides of the equation by 2a

x = 6/2a

x = 3/a

3. -ax - 20 = -14

-ax = -14 + 20

-ax = 6

x = 6/-a

x = -6/a

Therefore, the solutions are:

1. x = -a/6

Step-by-step explanation:

The estimate of the amount 28,945,000 is 3 × 10⁷

An estimate is a rough or approximate calculation or judgement value.

The question is with regards to the scientific notation which is of the form a × 10ᵇ, where absolute a is of a value 1 ≤ a < 10

The scientific notation form of a number is found as follows;

The decimal point on the number is moved from its position to the point such that the number of non zero numbers to the left of the decimal point is 1

The number b is the number of places to which the decimal point is moved.

b is positive when the decimal point is moved to the left

b is negative when the decimal point in the number is moved to the right

b is zero when the decimal point is not moved

The scientific notation number formed, a × 10ᵇ, which is read as a times 10 raised to the power b.

The zeros in the tail to the right of the decimal point are removed

The number 28,945,000 in scientific notation is 2.8945 × 10⁷

Step-by-step explanation:

Standard form should look like:

Ax + By = C

and the numbers A,B, and C have to be whole numbers (actually integers, because negative is okay too except A has to be positive)

You have been given a point and the slope. There is a shortcut, fill-in-the-blank equation called point-slope that you can just fill in a point and the slope. Then we can change that equation into standard form.

Point-slope equation:

y - Y = m(x - X)

Fill in (5, -2), which is the (X, Y). 5 in place of X and -2 in place of Y. Fill in 2/5 for the m which is slope.

y - Y = m(x - X)

y - -2 = 2/5(x - 5)

simplify, and distribute.

y + 2 = 2/5x - 2

Multiply through by 5 to get rid of the fraction.

5y + 10 = 2x - 10

Subtract 10.

5y = 2x -20

Subtract 2x.

5y - 2x = -20

Rearrange the terms.

-2x + 5y = -20

Multiply through by -1 (because that A has to be positive)

2x - 5y = 20

The equation in standard form is:

2x - 5y = 20
