Answer:

  F  altitude

Step-by-step explanation:

AB is perpendicular to triangle base XZ, so is an altitude of the triangle.

__

Additional comment

B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)

Eliminating the choices that can't work leaves the one that does work. AB is the altitude.

Altitude

Answer:

[tex]y = \frac{5}{8} + x[/tex]

Step-by-step explanation:

Given

[tex]Kiran = x[/tex]

[tex]Andre = y[/tex]

[tex]Andre = \frac{5}{8}\ minutes\ more[/tex]

Required

Write an equation that represents the scenario

[tex]Andre = \frac{5}{8}\ minutes\ more[/tex] means that Andre read 5/8 minutes more than Kiran and this can be represented as:

[tex]Andre = \frac{5}{8} + Kiran[/tex]

Substitute x for Kiran

[tex]Andre = \frac{5}{8} + x[/tex]

Substitute y for Andre

[tex]y = \frac{5}{8} + x[/tex]

area = 6

Step-by-step explanation:

p = 4 + 3 + 7

a = L × w

2

Perimeter: 14m²n²cm

Area: 28m²n²

height: 4m²

length: 7mn²

base: 3mn²

Perimeter =?

Area=?

Perimeter: a + b + c

Area: length × height

Perimeter: a+b+c

= 4m²+7mn²+3mn²

= 14m²n² cm

Area: l×h

= 4m²×7mn²

= 28m²n²

Answer:

A.) False

Step-by-step explanation:

The triangle proportionality theorem can apply to all triangles, because if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. This situation does not just apply to right triangles.

Answer:

I think it's actually True

Step-by-step explanation:

The triangle proportionality theorem can apply to all triangles, because if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. This situation does not just apply to right triangles.

Step-by-step explanation:

Answer:

(2,1)

Step-by-step explanation:

2x - 2y = 2

5x + 2y = 12

2x + 5x = 7x

-2y + 2y = 0

2 + 12 = 14

7x = 14

7x/7 = 14/7

x = 2

2x - 2y = 2

2(2) - 2y = 2

4 - 2y = 2

-2y = 2 - 4

-2y = -2

-2y/-2 = -2/-2

y = 1

Step-by-step explanation:

For mixed fractions, mutiply the bottom and add the top Ex: 1x4=4 and 4+1=5 hence 1 1/4 being 5/4 and the second you just mulitply. 3X5=15 4X5=20 or 15/20.

Answer:

C

Step-by-step explanation:

Unit rate means that the denominator of the units has to be 1: units have to be miles/1 hour

Thus divide miles by hours to get the unit rate. The answer would then be 7/2 miles/1 hour

Answer:

each chair weighs 6 lbs and the crate weighs 18 lbs.

Step-by-step explanation:

The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.

let, each chair weigh = x

and, the crate weigh = y

so, we get,

the equations as:

8x + y = 66 ....(1)

11x + y = 84 ....(2)

now, solving this two equations,

we get,

subtracting (2) - (1),

3x = 18

or, x = 6

so, we have,

y = 18

Hence, The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.

Given:

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

To find:

The intersection point of all the medians of the triangle ABC.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

[tex]Centroid=\left(\dfrac{-3+3+0}{3},\dfrac{0+0+4}{3}\right)[/tex]

[tex]Centroid=\left(\dfrac{0}{3},\dfrac{4}{3}\right)[/tex]

[tex]Centroid=\left(0,1.333...\right)[/tex]

Round each coordinate to the nearest tenth.

[tex]Centroid=\left(0,1.3\right)[/tex]

The coordinates of required point are (0,1.3). Therefore, the correct option is C.

Answer:

You are finding the intersection point of the system of linear equations.

Step-by-step explanation:

You can use methods like substitution, elimination, and/or equal values to find the solution for the system of linear equations.

Answer:

The y-intercept is 0

Step-by-step explanation:

Here, we want to get the y-intercept value of y = sin x

From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0

So therefore, the y-intercept of y = sin x is 0
