Answer:

The equation in the point-slope form will be:

Step-by-step explanation:

Given

Using the point-slope form of line equation

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

here

substituting the values m = 2/3 and the point (-3, 5)  in the point-slope form of the line equation

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

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

Thus,  the equation in the point-slope form will be:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

NOTE: The equation in the point-slope can be further simplified such as:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{2}{3}\left(x+3\right)+5[/tex]

[tex]y=\frac{2}{3}x+7[/tex]

They will have 6 breads per 4 charm and there is 28, so they will need 42 breads.

Answer:

D- They will need 42 beads

Step-by-step explanation:

The answer is 42 beads becuase for every four charms there is six beads.

For starters, I had to figure out how many times 4 went into 28, which is 7. Than from there I did 7×6 and that got me 42.

Answer:

70 students

Step-by-step explanation:

As, 30% Mike surveyed

And these 30% are 21 students

So 30% of X = 21

= 30/100 x X = 21

= 30X = 2100

So X = 2100/30

X = 70

So 70 students were surveyed

There are 70 students did Mikey survey.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Of all the students that Mikey surveyed, 30% said they play baseball.

And, There are 21 students play baseball.

Now, Let number of students did Mikey survey = x

So, We can formulate;

⇒ 30% of x = 21

Solve for x;

⇒ 30/100 × x = 21

⇒ 30x = 2100

⇒ x = 70

Thus, The number of students did Mikey survey = 70

Answer the answer is b. 6 tickets cost $30

Step-by-step explanation:

Answer:

9x² + 33x + 28

Step-by-step explanation:

[tex](3x + 7)(3x + 4)\\= 3x(3x + 4) + 7(3x + 4)\\= 9x^2 + 12x + 21x + 28\\= 9x^2 + 33x + 28[/tex]

The expression  9[tex]x^2[/tex] + 33[tex]x[/tex] + 28 is the trinomial form of the expression (3x + 7)(3x + 4).

Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.

Expressions can be used to represent mathematical relationships, solve equations, simplify calculations, analyze functions, describe geometric figures, and more. They serve as fundamental tools in mathematical reasoning and problem-solving.

(3x + 7)(3x + 4) = 3x [tex]\times[/tex] (3x + 4) + 7 [tex]\times[/tex] (3x + 4)

= (3x [tex]\times[/tex] 3x) + (3x [tex]\times[/tex] 4) + (7 [tex]\times[/tex] 3x) + (7 [tex]\times[/tex] 4)

= 9[tex]x^2[/tex] + 12x + 21x + 28

Combine like terms to same sides:

= 9x^2 + 33x + 28

Therefore, the expression (3x + 7)(3x + 4) can be expressed as the trinomial 9x^2 + 33x + 28.

Answer:

x=4

Step-by-step explanation:

7/9 - x/9 = 1/3

I like to get rid of fractions so I will multiply each side by 9

9*(7/9 - x/9) = 1/3*9

7 - x = 3

Subtract 7 from each side

7-x-7 = 3-7

-x= -4

Multiply each side by -1

x =4

Answer:

Length = 3

Step-by-step explanation:

the formula for area of a rectangle is Area = Base (width) x Height (length)

so plug in out values: 3/2 = 1/2 x H

divide both sides by 1/2 to find the height/length: 3/2 ÷ 1/2 = Height

to divide a fraction by a fraction, flip the divisor and change the sign from ÷ to ×

so you get 3/2 × 2/1 = Height

the 2 cancels out, so you get: 3 = height/length

Answer:

32 + 6w

Step-by-step explanation:

Total number of shows Jonah has recorded after w weeks is 26+6w

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant

Given,

Jonah has recorded 32 shows using his cable television server

Initial term a= 32

Each week he records 6 new shows

Common difference d=6

Sequence is in arithmetic progression

nth term = a+(n-1)d

Therefore,

Total number of shows Jonah has recorded after w weeks

=32+(w-1)6

=32+6w-6

=26+6w

Hence, the Expression to show the total number of shows Jonah has recorded after w weeks is 36+6w

C.using sin(30⁰).

because A=sin 30⁰bh

Answer:

Step-by-step explanation:

A is correct.

2/3 > 4/8

5/9 > 7/12    This one is close. They are both nearly 1/2, but 9<12 and when you divide something by 9 the remainder is going to be larger than if you divide by 12.

The second one is incorrect.

3/4 > 5/9    5/9 is close to 1/2. Three quarters is much greater than 1/2

3/10 is much smaller than 5/9

The third one is correct. 1/10 and 5/6 are much larger than the two fractions on the right. The right side = 56/60 which is very nearly one. The left side is nowhere near that large. (I did estimate the right side).

The fourth one is correct. 9/10 is much larger than 2/3 and 5/9 is larger than 5/12. 5/9 is over 1/2 and 5/12 is under one half. So the arrow in the fourth one is going the right way.

Step-by-step explanation:

The value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex].

Trigonometric functions are  the periodic functions which denote the relationship between angle and sides of a right-angled triangle.

We have,

[tex]Sin(A) = \frac{4}{5}[/tex] ,    [tex]\frac{\pi }{2} < A < \pi[/tex]

[tex]Sin(B) = \frac{-2\sqrt{5} }{5}[/tex] ,   [tex]\pi < B < \frac{3\pi }{2}[/tex]

So,

Using identity ;

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

So,

First find [tex]SinB[/tex] and [tex]CosA[/tex];

i.e.

[tex]CosB=\frac{-\sqrt{5} }{5}=\frac{-1}{\sqrt{5} }[/tex],   [tex]\pi < B > \frac{3\pi }{2}[/tex]

[tex]CosA=\frac{-3}{5}[/tex],    [tex]\frac{\pi }{2} < A > \pi[/tex]

Now,

Substituting values,

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

[tex]Cos(A - B)= ((\frac{-3}{5})\ *\ \frac{-1}{\sqrt{5}} ) +((\frac{4}{5})\ *\ \frac{-2\sqrt{5} }{5} )[/tex]

Simplify,

[tex]Cos(A - B)= (\frac{3 }{5\sqrt{5}} ) -(\frac{8 }{5\sqrt{5}})[/tex]

[tex]Cos(A - B)= (\frac{-5 }{5\sqrt{5}} )[/tex]

[tex]Cos(A - B)= (\frac{-1 }{\sqrt{5}} )[/tex]

Or we can write

[tex]Cos(A - B)= (\frac{-\sqrt{5} }{5} )[/tex]

Hence, we can say that the value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex] which is given in option (b).
