Answer:

p = 8

Step-by-step explanation:

17 = 3 ( p - 5 ) + 8

Distribute

17 = 3p - 15 + 8

Simplify

17 = 3p - 7

Inverse operations

17 = 3p - 7

+7         +7

24 = 3p

/3    /3

8 = p

Answer:

[tex]p=8[/tex]

Step-by-step explanation:

First you need to distribute the 3 with the values in the parentheses.

[tex]3*p= 3p\\3*-5=-15[/tex]

[tex]17=3p-15+8[/tex]

Then combine like terms...

[tex]17=3p-7\\17+7=3p-7+7\\24=3p\\\33p= 24[/tex]

Divide by 3 to get the variable by itself.

[tex]\frac{3p}{3}=\frac{24}{3}\\p=8[/tex]

Answer:

B BE⊥AC, CF ⊥AB

Step-by-step explanation:

on Edge

In the given triangle ABC, point D is orthocenter when BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.

"The orthocenter is the point where all the three altitudes of the triangle cut or intersect each other."

In the given triangle ABC, to be an orthocenter, all three lines that are drawn from the points A, B, and C are must be perpendicular to the opposite side of the triangle.

Therefore,  AG must be perpendicular to BC, BE must be perpendicular to AC, and CF must be perpendicular to AB.

Step-by-step explanation:

5/12

2/5

Yes they are proportion.

The first one 25/60 means both the 5 and 12 can be multiplied by 5 to get the 25/60.

The second one 8/20 means that both the 2 and 5 can be multiplied by 4 to get the 8/20.

f(x) = x - 1

g(x) = 2x

To compute g(f(x)), replace every instance of x in the definition of g(x) with f(x). This would given you

g(f(x)) = g (x - 1) = 2 (x - 1) = 2x - 2

♡ The Question ♡

-You are 5 years older than your cousin. How old is your cousin when you are 12 years old?

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Answer ♡

- Your cousin is 7.

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- If you're 5 years OLDER than your cousin, you are going to be subtracting. Why?: You are provided the age of you which is '12.' So if you're 5 years older than your cousin you're subtracting your age which is 12 from 5!

12 - 5 = 7

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ Tips ♡

-Try to look at the keywords around the words to figure out an equation to use, then afterwards attempt to solve! Feel free to use a calculator if you're struggling!

Answer:

This equation is in standard form, so to make graphing easier you need to put it in y=mx+b form or slope, intercept form.

Step-by-step explanation:

I have attached a photo of what the graph would look like.

However, in the future you should know how to turn this into a slope intercept equation.

-2x+7y=-21

+2x        +2x

7y=2x-21

divide the entire equation by 7

y= 2/7x-3

That is a full equation in slope intercept form.

Hopefully this helps!

The graph of the linear equation -2x + 7y = -21 is a line passing through the points (0, -3) and (10.5, 0) which is given below.

Given a linear equation:

-2x + 7y = -21

It is required to graph the linear equation.

In order to graph this, first, it is required to find the points through which it passes.

Substitute x = 0.

7y = -21

y = -3

So, the line passes through (0, -3), which is the point where the line touches the y-axis.

Substitute y = 0.

-2x = -21

x = 10.5

So, the line passes through (10.5, 0), which is the point where the line touches the x-axis.

Draw a line passing through these points. This is the graph.

Hence, the line passes through the points (0, -3) and (10.5, 0).

Answer:

< S = 32

Step-by-step explanation:

< S = 180 - (< R + < T)

< R = < T

15x - 31 = 9x + 11

6x = 42

x = 7

< R = 74

< S = 180 - (74 + 74)

< S = 180 - 148

< S = 32

What is the permutation and combination?

Permutation and Combination form the principles of counting and they are applied in various situations.

A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.

Here given that,

A blood bank needs [tex]5[/tex] people to help with a blood drive. [tex]18[/tex] people have volunteered.

So,

[tex]^nC_r=\frac{n!}{r(n-r)!}[/tex]

Here [tex]n=18, r=5[/tex]

Then

[tex]^{18}C_5=\frac{18!}{5(18-5)!}\\\\^{18}C_5=\frac{18!}{5(13)!}\\\\^{18}C_5=\frac{(18)(17)(16)(15)(14)(13)}{5(13)}\\\\^{18}C_5=\frac{(18)(17)(16)(15)(14)}{5}\\\\^{18}C_5={(18)(17)(16)(3)(14)}\\\\^{18}C_5=205632[/tex]

Hence, the different groups of [tex]5[/tex] can be formed from the [tex]18[/tex] volunteers is

[tex]^{18}C_5=205632[/tex].

Step-by-step explanation:

h determines how much d she will get and hence B and D are wrong

independent variable means the cause

dependent variable means the effect

3/4 = 0.75

0.75 * 200 = 150

The simplified form of the given expression is 150.

Given that, 3/4 ×200.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Here, 3/7 =0.75

So, 0.75 ×200

= 150

Hence, the simplified form of the given expression is 150.

Answer:

Use the pythagorian theorm

Step-by-step explanation:

Answer:

x = 15/2

Step-by-step explanation:

the smaller triangle missing side by using pythagorean theorem

a^2 + b^2 = c^2

4^2 + b^2 = 5^2

b^2 = 25-16=9

b=3 the missing leg for the small triangle;

now use proportionality by saying [tex]\frac{4}{6}[/tex] = [tex]\frac{3}{y}[/tex]; where y is the one leg in the larger triangle

y = 6*3/4 = 9/2

use pythogorean theorem again

a^2 + b^2 = x^2

6^2 + (9/2)^2 = x^2

36 + 81/4 = x^2

144/4 + 81/4 = x^2

225/4 = x^2

x = 15/2
