Solve the inequality 21<2x+3

Answer:

34cm

Step-by-step explanation:

To find the missing sides you have to see how much the bottom is, then the other sides so in the case the bottom is 10cm and top is 3cm on each side. and you want to find the middle. so you would do 10 - 3 - 3 = 4

Answer:

81.64

Step-by-step explanation:

im using 3.14 not all of pi is that ok

Answer:

81.64

Step-by-step explanation:

Write the equation 13r * 3.14

First do 13(2) to get 26

Secondly do 26 times 3.14

this will give you 81.64

Answer:

C. 9 lbs.

Step-by-step explanation:

80 ounces = 5 pounds

64 ounces = 4 pounds

5 pounds + 4 pounds =

9 pounds / 9 lbs.

Answer:

128degrees

Step-by-step explanation:

Note that the given triangle ABC is an isosceles triangle with base angles equal, hence;

m∠BAC = m∠BCA

7x+1 = 5x+9

7x - 5x = 9-1

2x = 8

x = 8/2

x = 4

m∠BAC = 5x+6

m∠BAC = 5(4)+6

m∠BAC = 26 degrees

The vertex angle = 180 - (26+26)

The vertex angle = 180 - 52

The vertex angle = 128degrees

Answer:

17h = 153, h = 9 (B)

Step-by-step explanation:

17h = 153

h = 153/17

h = 9

Answer:

x=0, y = 3/2

Step-by-step explanation:

Ok, for substitution, you need to solve for y in terms of x, I'll do this for the first eqyation

8y=-7x+12

y=-7/8x+3/2, now plug in y in the second equation

-4x+2(-7/8x+3/2)=3, solve for x now

-4x-7/4x+3=3,

-4x-7/4x=0, x=0 now plug in 0 for either equation to solve for y

-4(0)+2y=3

2y=3, y=3/2

Answer:

B

Step-by-step explanation:

A bisector splits the angle up into 2 angles that are equal to each other so all we do is set up an equation and the equation is

4x+6=6x-10

subtract 4 from each side

6=2x-10

add 10 to each side

16=2x

divide each side by 2

x=8

then we just plug in 8 to 6x=10

6(8)-10

6x8=48

48-10=38

WUT = 38

Answer:

(–8, –4)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the reduction or enlargement of the size of an object by a factor.

Given that triangle XYZ was dilated using the rule (x, y) ⇒ (0.25x, 0.25y) to produce triangle X'Y'Z' with points at  X'(-4, 5), Y'(-6, -1) and Z'(-2, -1)

Since (x, y) ⇒ (0.25x, 0.25y)

(x, y) ⇒ 0.25(x, y)

4(x, y) ⇒ (x, y)

We can find the points of XYZ by multiplying by 4

hence:

X = 4(-4, 5) = (-16, 20)

Y = 4(-6, -1) = (-24, -4)

Z = 4(-2, -1) = (-8, -4)

Answer:

Step-by-step explanation:

f(x) = ln x

g(x) = - f(x - 4)

g(x) = - ln (x - 4)

g(5) = - ln (5 - 4) = - ln 1 = 0

Answer:

The result in standard form is:

[tex]\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t[/tex]

Step-by-step explanation:

Given the polynomials

subtracting 8t² + t from -5t+ 4t² – t.

[tex]\left(-5t+\:4t^2\:-\:t\right)\:-\:\left(8t^2\:+\:t\right)[/tex]

Remove parenthese: (-a) = -a

i.e. - (8t² + t) = 8t² - t

so the expression becomes

[tex]=-5t+4t^2-t-8t^2-t[/tex]        

grouping the like terms

[tex]=4t^2-8t^2-5t-t-t[/tex]

Add similar elements: 4t² - 8t² = -4t²

[tex]=-4t^2-5t-t-t[/tex]

Add similar elements: -5t - t - t = -7t

[tex]=-4t^2-7t[/tex]

Therefore, the result in standard form is:

[tex]\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t[/tex]

Answer:

$123.48 per week

Step-by-step explanation:

$ = (13.72)(9)

Multiply:

$123.48

The earnings of Adam based on the given rate will be $123.48.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

Adam earns $13.72 each hour.

For 9 hours the earnings will be,

⇒ $13.72/hour × 9 hour

⇒ $123.48

Hence "The earnings of Adam based on the given rate will be $123.48".

Answer:

To prove that N is a proper subset of M, show that every element of N is an element of M but there exists some elements of M which are not in N.

M= {4, 8, 12, 16, 20, 24...}

N= {12, 24, 36, 48, 60...}

Similar to example 6, 12 is a multiple of 4.

If x∈N,

then x= 12m for some positive integer m.

∴ x= 4(3m)

Hence, x is a multiple of 4.

i.e. x∈N.

Thus, every element of N is an element of M, but there exists some elements of M which are not elements of N. For example, 4, 8 and 16 are elements of M but are not elements of N. Thus, N is a proper subset of M. (shown)

Explanation:

∈ is the symbol of 'element of'. Thus, x∈N means that x is an element of N.

☆ Think of subsets like subtopics:

If differentiation is a subtopic of calculus, differentiation is a part of calculus but calculus is not only about differentiation since it includes integration too. Thus, there are numbers, which we call elements, in M that are not in N but all elements in N are in M.

Answer:

n=4

Step-by-step explanation:

Combine multiplied terms into a single fraction

3 4 = 3 3 4 = 3 2

Multiply all terms by the same value to eliminate fraction denominators

3 4 = 3 4 ⋅ 3 4 = 4 ⋅ 3 3

Simplify

Cancel multiplied terms that are in the denominator

Multiply the numbers

3 = 1 2 4

Divide both sides of the equation by the same term

3 = 1 2 3n 3 = 1 2 3 5

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

= 4

Solution

= 4
