In parallelogram EFGH, what is the relationship between angle e and angle f?

e° = f°
e° + f° = 180°
e° = -f°
e° - f° = 180°

Answer:

Go with anything, and I mean ANYTHING that is in a numerical order with an outlier

LITERALLY 1,2,3,4,5,6,7,8,9,100

you will get a median of 5.5 but with the high outlier, you will get a mean of 14.5

Step-by-step explanation:

Slope of the line connecting the points (1,-1) & (3,5) is 6/2 = 3

so the equation using point form y-y1 = m(x-x1)

y+1 = 3(x-1) = 3x-3

y=3x-4

Answer:

185 children and 35 adults

Step-by-step explanation:

first equation: 6x+4y=1250

second equation: x+y=220

work:

6x+4y=1250 (-1)

x+y=220 (6) we eliminate x, that's why I multiply each term by 6 and -1

-6x-4y=-1250

6x+6y=1320

2y=70

2y/2=70/2

y=35 (I used y for adults)

x+35=220

x=220-35

x=185 (and I used x for children)

Answer:

The distance is approximately 3.6

Step-by-step explanation:

The distance from a point (xo, yo) to a line ax+by+c=0 is the shortest distance from the given point to any point on the line.

It can be calculated with the formula:

[tex]\displaystyle d={\frac {\mid ax_{0}+by_{0}+c\mid}{\sqrt {a^{2}+b^{2}}}}[/tex]

The coordinates of point A are (1,-2). The equation of the line must be found by knowing two clear points it passes through.

These points are (0,3) and (6,-1). First, we calculate the slope:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle m=\frac{-1-3}{6-0}=\frac{-4}{6}=-\frac{2}{3}[/tex]

The equation of the line in slope-point form is:

[tex]y=m(x-x_o)+y_o[/tex]

Taking the point (0,3) and the slope above:

[tex]\displaystyle y=-\frac{2}{3}(x-0)+3[/tex]

Multiply by 3:

[tex]3y=-2x+9[/tex]

Moving all terms to the left side:

[tex]2x+3y-9=0[/tex]

We now have all the required values to calculate the distance:

a=2, b=3, c=-9, xo=1, yo=-2

[tex]\displaystyle d={\frac {\mid 2\cdot 1+3\cdot (-2)+(-9)\mid}{\sqrt {2^{2}+3^{2}}}}[/tex]

[tex]\displaystyle d={\frac {\mid 2-6-9\mid}{\sqrt {13}}}\approx 3.61[/tex]

The distance is approximately 3.6

Answer:

x = - 3

Step-by-step explanation:

given a parabola in standard form y = ax² + bx + c (a ≠ 0 )

then the equation of the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 6x - 9 ← is in standard form

with a = 1, b = 6 , then the equation of the axis of symmetry is

x = - [tex]\frac{6}{2}[/tex] = - 3 , that is x = - 3

Replace y = -4x into y = 3x + 28

-4x = 3x + 28

Minus both side by 3x

-7x = 28

x = -4

Recheck : - 4 x (-4) = 3 x (-4) + 28
16 = -12 +28 = 16 (t)

Answer:

(- 4, 16 )

Step-by-step explanation:

y = 3x + 28 → (1)

y = - 4x → (2)

substitute y = 3x + 28 into (2)

3x + 28 = - 4x ( add 4x to both sides )

7x + 28 = 0 ( subtract 28 from both sides )

7x = - 28 ( divide both sides by 7 )

x = - 4

substitute x = - 4 into (2)

y = - 4(- 4) = 16

solution is (- 4, 16 )

The sample in the table is used to show the preference of each student

156 students preferred country music

From the question, we have:

Country = 6

Total students = 650

Total proportion = 25 i.e. 12 + 7 + 6

So, the number of students that preferred country music is:

Country = 6/25 * 650

Evaluate the product

Country = 156

Hence, 156 students preferred country music

Answer:

2/3 or -5 is correct for all future users.

Step-by-step explanation:

The roots of the quadratic equations or the values of x are -5 and 2/3.

A quadratic equation is an algebraic equation of degree two. An algebraic equation of degree n has exactly n number of roots.

Given a quadratic equation 3x² + 13x = 10 which can be written as,

3x² + 13x - 10 = 0.

Now two numbers that add to 13 and multiplied to -30 are 15 and - 2.

3x² + 15x - 2x - 10 = 0.

3x(x + 5) - 2(x + 5) = 0.

(x+5)(3x-2) = 0.

x + 5 = 0 OR 3x -2 = 0.

x = -5 OR x = 2/3.

a=12      b=25 degrees

Step-by-step explanation:

the tangent of the 25 degree angle gets you your answer

Trigonometry ('triangle', or 'measure') is the branch of mathematics that studies relationships between side lengths or the angles of the triangles

by the question, we have the following parameters:

Vertical Leg = x

Base length = 12

Angle at the vertical side = 25 degrees

The measure of the x is then calculated using the following tangent ratio

tan(x) = Base length / Vertical leg

Substitute known values

tan(x) = 12/x

So, the trigonometric expression that it is be used for find the value of x is tan(x) = 12/x
