Answer 1

Answer:

y = 9

Step-by-step explanation:

if you want to find the value of y then

4y + 6y = 90 (it's right angle triangle)

10 y = 90

y = 90/10

y = 9

Answer 2

Answer:

y = 9

Step-by-step explanation:

6y + 4y = 90

Answers

Problem 1

Answer:  x = 8

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

Explanation:

The tickmarks say that TU and UV are the same length. Both are 23 units each. They combine to TU+UV = 23+23 = 46, which is the length of TV

TV = 5x+6

TV = 46

5x+6 = 46

5x = 46-6

5x = 40

x = 40/5

x = 8

===========================================================

Problem 2

Answer:  QR = 53

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

Explanation:

We use the same idea as the previous problem.

PQ = 6x-1 is the same length as QR

PQ+QR = (6x-1)+(6x-1) = 12x-2 = PR

Since PR = 15x-29, we can then say,

PR = 12x-2

15x-29 = 12x-2

15x-12x = -2+29

3x = 27

x = 27/3

x = 9

From there,

PQ = 6x-1 = 6(9)-1 = 53QR = 53  since PQ and QR are the same lengthPQ+QR = 53+53 = 106PR = 15x-29 = 15(9)-29 = 135-29 = 106

This shows that PQ+QR = PR is true and it helps confirm the answer.

Answers

Answer:

first n = 5

sec n = 11

third n = 24

Step-by-step explanation:

40-6+1 = 35

35/7 = 5

1st no = 5

2nd no = first + 6

= 5+6

= 11

3rd no = 5(first) - 1

-5x-y=12

x+y=4

-6x+9y=11

Answers

Answer:

1.  x = -12+y / 5 , y = -12-5x

2.  x = 4 - y , y = 4 - x

3.  x = -11 - 9y / 6 , y = 11 + 6x / 9

( for the numbers in fractions such as the x value for #1 and x & y value for #3, put the negative sign in front of the fraction, not the number okay? )

Step-by-step explanation:

-5x - y = 12

--->  -5x - y = 12                                          -5x - y = 12

= -5x - y = 12                                           =  +5x        +5x

        +y     +y                                             ---------------------

---------------------                                              -y = 12 + 5x

-5x = 12 + y                                                    /-1         /-1

/-5     /-5                                                      ----------------------

---------------------                                                y = -12-5x

x = -12+y / 5

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

x + y = 4

--->  x + y = 4                                                   x + y = 4

=          -y    -y                                              =  -x         -x

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

x = 4 - y                                                             y = 4 - x

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

-6x + 9y = 11

-----> -6x + 9y = 11                                               -6x + 9y = 11

=              -9y    -9y                                          =   +6x          +6x

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

-6x = 11 - 9y                                                             9y = 11  + 6x

Answers

Answer:

c. b= 4/11

d. b= -4/11

Step-by-step explanation:

b^2 = 16/121

Take the square root of each side

sqrt(b^2) =± sqrt(16/121)

b = ±4/11

S O L U T I O N :

b² = -16/121

16 is 4² and 121 is 11²

b² = -4²/11²

b² = -(4/11)²

When exponents are common they are eliminated. Here, 2 is common

b = ±4/11

Hence, the answer is ±4/11

Answer:

Step-by-step explanation:

Find the equation of the line passes through ( -3, 4) and parallel to the line 2y-4x + 2 = 0

Answer:

[tex]y = x + 1[/tex]

Step-by-step explanation:

We want to determine the equation of the line that passes through the point (3, 4) and is parallel to the line containing the points (3, 5) and (0, 2).

Recall that parallel lines have equivalent slopes.

Hence, first find the slope of the line containing the points (3, 5) and (0, 2):

[tex]\displaystyle m = \frac{\Delta y }{\Delta x} = \frac{(2)-(5)}{(0)-(3)} = \frac{-3}{-3} = 1[/tex]

Therefore, the slope of our new line must also be 1.

We are given that it passes through the point (3, 4). Since we are given a slope and a point, we can consider using point-slope form:

[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]

Substitute:

[tex]\displaystyle y - (4) = (1)(x - (3))[/tex]

Simplify:

[tex]y - 4 = x - 3[/tex]

And add. Hence, our equation in slope-intercept form is:

[tex]y = x + 1[/tex]

In conclusion, the line that passes through the point (3, 4) and is parallel to the line containing the two points (3, 5) and (0, 2) is:

[tex]y = x + 1[/tex]

how to find standard form given 2 points

Answers

9514 1404 393

Answer:

  (y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)

Step-by-step explanation:

The standard form equation of a line is of the form ...

  ax +by = c

where a, b, c are mutually prime integers. The leading coefficient must be positive.

__

The standard form equation of a line can be found for the two points (x1, y1) and (x2, y2) using the formula ...

  (y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)

Using this equation, you must choose y2>y1. If y2=y1, you must choose x1>x2.

You will need to eliminate any fractions by multiplying the equation by an appropriate number. Once you have the numbers figured out, you need to factor out any common factors from the coefficients and the constant, so they are all mutually prime.

passes through (-2, 3) and is perpendicular to y = 1/4x - 4

Answers

Answer:

[tex]\displaystyle y = -4x - 5[/tex]

Step-by-step explanation:

We want to find the slope-intercept form of the equation that passes through the point (-2, 3) and is perpendicular to the line:

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

Note that this line has a slope of 1/4.

Recall that the slopes of perpendicular lines are negative reciprocals of each other.

Since the slope of our old line is 1/4, the slope of its perpendicular line must be -4.

We are also given that it passes through the point (-2, 3). So, we can consider using point-slope form:

[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]

Let (-2, 3) be (x₁, y₁) and substitute -4 for the slope m. Hence:

[tex]\displaystyle y - (3)= -4 (x - (-2))[/tex]

Convert into slope-intercept form. Simplify:

[tex]\displaystyle \begin{aligned} y -3 &= -4 (x + 2) \\ y - 3 &= -4x - 8 \\ y &= -4x -5\end{aligned}[/tex]

In conclusion, the perpendicular line that passes through the point (-2, 3) is given by:

[tex]\displaystyle y = -4x - 5[/tex]

Answers

Answer:

B

Step-by-step explanation:

Using the rules of logarithms

log x + log y = log (xy)

[tex]log_{b}[/tex] x = n , then x = [tex]b^{n}[/tex]

Given

[tex]log_{4}[/tex] (x + 3) + [tex]log_{4}[/tex] x = 1 , then

[tex]log_{4}[/tex] x(x + 3) = 1

x(x + 3) = [tex]4^{1}[/tex] = 4

x² + 3x = 4 ( subtract 4 from both sides )

x² + 3x - 4 = 0 ← in standard form

(x + 4)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 1 = 0 ⇒ x = 1

However, x > 0 , thus x = 1

Answers

Answer:

7087.8m or 7.09km

Step-by-step explanation:

formula used:

distance = speed * time

total distance = distance1 + distance2

let d1 be distance1, d2 be distance2, s1 be speed1, s2 be speed2, t1 be time1, and t2 e time2:

s1 = 5.8m/s, t1 = 12.9 min or 774 sec, s2 = 6.10m/s, t1 = 7.1 min or 426 second

d1 = s1 * t1

   = 5.8 m/s * 774 s

   = 4489.2 m

d2 = s2 * t2

   = 6.10 m/s * 426 s

   = 2598.6 m

total distance = d1 + d2

                       = 4489.2m + 2598.6m

                       = 7087.8 meter or 7.09 kilometer

Write down the temperature that is 7 °C below -3°C.
ES

Answers

Answer:

-10 [tex]^\circ C[/tex]

Step-by-step explanation:

Subtract 7 from -3.   -3 - 7 = 0=-10

The temperature that is 7°C below -3°C is equal to -10°C.

To find the temperature that is 7°C below -3°C, we need to subtract 7 from -3. When subtracting a positive number from a negative number, the result becomes more negative.

Starting with -3°C, we subtract 7°C:

-3°C - 7°C = -10°C

A negative temperature indicates a temperature below zero on the Celsius scale. In this case, -10°C means that the temperature is 10 degrees below freezing point.

The Celsius scale is based on the freezing and boiling points of water, with 0°C representing the freezing point and 100°C representing the boiling point at standard atmospheric pressure.

Since we are subtracting 7°C, we are moving further below the freezing point. So, -10°C indicates a colder temperature than -3°C.
