Answer:

thirteen sixteenths

Step-by-step explanation:

Three eighths plus seven sixteenths equals blank

3/8 + 7/16 = ?

= (2*3)+(1*7)/16

= (6+7)/16

= 13/16

13/16 is equivalent to thirteen sixteenths

30 eggs

Step-by-step explanation:

Given:

A line passes through (1,-2) and is perpendicular to [tex]-4x+7y=21[/tex].

To find:

The equation of that line.

Solution:

We have, equation of perpendicular line.

[tex]-4x+7y=21[/tex]

Slope of this line is

[tex]m_1=-\dfrac{\text{Coefficient of x}}{\text{Coefficient of y}}[/tex]

[tex]m_1=-\dfrac{-4}{7}[/tex]

[tex]m_1=\dfrac{4}{7}[/tex]

Product of slope of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]\dfrac{4}{7}\times m_2=-1[/tex]

[tex]m_2=-\dfrac{7}{4}[/tex]

Now, slope of required line is [tex]-\dfrac{7}{4}[/tex] and it passes through (1,-2). So, the equation of line is

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

where, m is slope.

[tex]y-(-2)=-\dfrac{7}{4}(x-1)[/tex]

[tex]4(y+2)=-7(x-1)[/tex]

[tex]4y+8=-7x+7[/tex]

[tex]4y+7x=7-8[/tex]

[tex]7x+4y=-1[/tex]

Therefore, the equation of required line is [tex]7x+4y=-1[/tex].

Answer:

Select the proportional relationship.

That is the only thing that is in the checkbox. It won't let you continue unless you get something.

Answer:

Step-by-step explanation:

use known angles and rules to find unknown values

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.

1= 75

2=180-75=105

Answer:

Please check the graph of the function y=-2x+5 attached below.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the function

[tex]y=-2x+5[/tex]

comparing with the slope-intercept form of the line equation

The slope m = -2

The y-intercept b = 5

The graph of y=-2x+5 is attached below.

Determining the y-intercept from the graph

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 5

Thus, the y-intercept b = 5

Please check the graph of the function y=-2x+5 attached below.

Answer:

3 2/11

Step-by-step explanation:

4 3/8 = 4 + 3/8 = 32/8 + 3/8 = 35/8

1 3/8 = 1 + 3/8 = 8/8 + 3/8 = 11/8

then:

4 3/8 ÷ 1 3/8 = (35/8) / (11/8) = 35/11

35/11 = 33/11 + 2/11 = 3 2/11

Answer:

[tex]4 \frac{3}{8} \div 1 \frac{3}{8} = \frac{35}{8} \div \frac{11}{8} = \frac{35}{8} \times \frac{8}{11} = \boxed{\frac{35}{11} }[/tex]

Answer:

The slope is 2/5

Step-by-step explanation:

Calculating the Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

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

We are given the points (-5, -2) (5, 2). Let's compute the slope:

[tex]\displaystyle m=\frac{2-(-2)}{5-(-5)}[/tex]

[tex]\displaystyle m=\frac{4}{10}[/tex]

Simplifying:

[tex]\displaystyle m=\frac{2}{5}[/tex]

The slope is 2/5

The simplified version of 3(9h + 4) is 27h + 12 because you are multiplying 3 and 9h to get 27h, and 4 and 3 to get 12

Hope this helped! :D

Answer:

27h + 12

Step-by-step explanation:

The simplified version of 3(9h + 4) is 27h + 12 because you are multiplying 3 and 9h to get 27h, and 4 and 3 to get 12

Answer:

9

Step-by-step explanation:

-6+2y=12

+6 +6

2y=18

2 2

9

..............................

x=-9/2

x=-3/4

x = 6

y = 21

y = 2x + 9

y = 4x - 3

2x + 9 = 4x - 3

• Get the like-terms together:

9 + 3 = 4x - 2x

12 = 2x

• Divide 2x and 12 by 2 (to get x by itself):

12 ÷ 2 = 2x ÷ 2

6 = x OR x = 6

• To find the value of y, we have to substitute x into one of the equations (it doesn't matter which equation you plug x into, if the value of x is correct, both will equal the same number):

y = 2(6) + 9

y = 12 + 9

y = 21

y = 4(6) - 3

y = 24 - 3

y = 21

Answer:

It's not a right triangle because [tex]16^{2} + 18^{2} > 24^{2}[/tex]

Step-by-step explanation:

[tex]16^{2} + 18^{2} > 24^{2}[/tex]

[tex]16^{2} = 256\\\\18^{2} = 324\\\\256 + 324 = 580\\\\580>24^{2} \\\\24^{2} = 576\\\\580>576[/tex]
