Find X using the Pythagorean Theorem

Answer:

ummmmmm....post the pic at least

Answer:

x > -7

-7x > 49

Multiply both sides by (-1) (Reverse inequality)

(-7x) (-1) < 49 (-1)

Simplify

7x < -49

Divide both sides by 7

7x/7 < -49/7

Simplify = x > -7

Answer:

Value of x is 92°.

Step-by-step explanation:

The given figure is a cyclic quadrilateral. All the sides of the quadrilateral touches the circle. So, the sum of the opposite angles will always be 180°.

88° + x° = 180°

x° = 180° - 88°

Answer:

we will write 972 in standard form

Step-by-step explanation:

Standard form of a given number 972 is equals to 9.72 × 10².

" Standard form is defined as the mathematical expression, number, any equation , quantity with certain rules defined for it."

According to the question,

Given number = 972

Standard form of writing a number is

Given number should be express as a decimal number between 1.0 to 10.0

multiply by power of 10.

Standard form of 972 =  9.72 × 10²

Hence , standard form of a given number 972 is equals to 9.72 × 10².

Answer:

The options are not given, so I will answer in a general way:

A quadratic equation can be written, in general form, as:

y = a*x^2 + b*x + c

Then if we want this, we need to replace:

a = 1

b = -3

c = -5

Then the equation that we want is:

y = x^2 - 3*x - 5

Is likely that the options are in the factorized way to write a quadratic equation (so it is kinda harder to you)

Such that the factorized way is written as:

y = (x - k)*(x - h)

where k and h are the roots of the quadratic equation.

So you just need to expand that expression and find the one that looks like:

y = x^2 - 3*x - 5

Just to be complete, let's find the factorized form of this particular quadratic equation.

The roots are given by:

0 = x^2 - 3*x - 5

And the two solutions are given by Bhaskara's formula:

[tex]x = \frac{-(-3) \pm \sqrt{(-3)^2 - 4*1*(-5)} }{2*1} = \frac{3 \pm 5.39}{2}[/tex]

The two roots are:

h = (3 + 5.39)/2 = 4.195

k = (3 - 5.39)/2 = -1.195

Then the factorized form is:

y = (x - 4.195)*(x + 1.195)

Answer:

If you need the temperature at 11:00 am it is 78 degrees.

Step-by-step explanation:

84-6=78 degrees

The mathematical sentence that expresses the information is t + 8 > 82

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The current temperature is represented by t.

If the temperature rises by 8  degrees, then the new temperature would be t + 8.

The record-high temperature for that date is 82 degrees.

If t + 8 is greater than 82, then the temperature would break the record-high temperature for that date.

Therefore, the mathematical sentence that expresses the information above is t + 8 > 82

Answer:

y=4x/3+17

Step-by-step explanation:

4/3=y-5/x+9

y=4x/3+17

The equation in point-slope form for this line is -

(y - 5) = (4/3)(x + 9)

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

We have a line that passes through the point (-9,5) and has a slope of

4/3.

The point slope form is given by -

(y - y₁) = m(x - x₁)    

Now, we can write the equation as -

(y - 5) = (4/3)(x + 9)

Therefore, the equation in point-slope form for this line is -

(y - 5) = (4/3)(x + 9)

[tex]\checkmark[/tex] The measure of the reference angle is [tex]45^{\circ}[/tex]

Step-by-step explanation:

The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have [tex]360-315=\boxed{45^{\circ}}[/tex] (*Note: [tex]\frac{7\pi}{4}=315^{\circ}[/tex], use [tex]\pi=180^{\circ}[/tex] to convert to degrees)

Step-by-step explanation:

Convert 7π/4 to degrees

You'll have 315°

Reference angle is the angle that a given angle makes with the abscissa or x-axis.

360-315 = 45°

THE MEASURE OF THE REFERENCE ANGLE IS 45°

Using the order of the letters in the triangles find the corresponding sides:

BL is similar to JF

LT is similar to KF

BT is similar to JK

Find the scale between LT and KF

9/12 = 3/4

The smaller triangle is 3/4 the size of the lager one.

This means BT = 3/4(JK) = 3/4(4) = 3

So x = 3, so side BL = 2x = 2(3) = 6

Now to solve for y:

BL is 3/4(JF)

6 = 3/4(y)

Solve for y by dividing both sides by 3/4

Y = 6/(3/4)

Y = 8

X = 3, y = 8

We know this slope is negative. Meaning for the perpendicular crossing to work, it must have a positive slope. We know that 3=(1*M)+B. Perpendicular lines will have slopes that are negative reciprocals of one another.
