Pls help me this is 7th grade (ADVANCED)

Step-by-step explanation:

Let the points of the given coordinates ( -3 , -1 ) & ( 0 , 3 ) be A and B respectively.

[tex] \underline{ \underline{ \text{Given}}} : [/tex]

Let A ( -3 , -1 ) be ( x₁ , y₁ ) & B ( 0 , 3 ) be ( x₂ , y₂ )

[tex] \underline{ \underline{ \text{To \: Find}}} : [/tex]

[tex] \underline{ \underline{ \text{Solution}}} : [/tex]

[tex] \boxed{ \sf{slope = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} }}[/tex]

~Plug the known values and then simplify !

⟼ [tex] \tt{ \frac{3- ( - 1)}{0- ( - 3)}} [/tex]

⟼ [tex] \tt{ \frac{3 + 1 }{0 + 3} }[/tex]

⟼ [tex] \tt{ \frac{4}{3}} [/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \underline{ \boxed{ \tt{ \frac{4}{3}}}}}}}} [/tex]

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Answer:

y= -49.26 or -49 6/23

Step-by-step explanation:

First distribute the 23 to y and 57

23y+1311=178

then subtract 1311 from both sides

23y=-1133

Then divide 23 to both sides

y= -49.2608695652

rounded: -49.3

as a fraction: -49 6/23

Answer:

Price per mechanical pencil: [tex]\$ 0.5[/tex].

Price per ruler: [tex]\$ 1[/tex].

Step-by-step explanation:

Let the cost per mechanical pencil be [tex]\$ p[/tex], and let the cost per ruler be [tex]\$ r[/tex].

Set up two equations based on the amount of money that each teacher paid.

The cost of [tex]50[/tex] mechanical pencils ([tex]\$ p[/tex] each) and [tex]30[/tex] rulers ([tex]\$ r[/tex] each) would be [tex](50 \, p + 30\, r)[/tex]. That should be equal to the amount of money that Mrs. Ortiz paid. In other words, [tex]50 \, p + 30\, r = 55[/tex].

Similarly, the cost of [tex]30[/tex] mechanical pencils ([tex]\$ p[/tex] each) and [tex]30 \![/tex] rulers ([tex]\$ r[/tex] each) would be [tex](50 \, p + 30\, r)[/tex]. That should be equal to the amount of money that Mr. Donahue paid. In other words, [tex]30 \, p + 30\, r = 45[/tex].

That gives a system of two equations:

[tex]\left\lbrace \begin{aligned}& 50 \, p + 30\, r = 55 \\ & 30 \, p + 30\, r = 45 \end{aligned}\right.[/tex].

Subtract the second equation for the first:

[tex]20\, p = 10[/tex].

[tex]\displaystyle p = \frac{1}{2} = 0.5[/tex].

In other words, the cost of one mechanical pencil would be [tex]\$0.5[/tex].

Substitute [tex]p = 0.5[/tex] back to either equation and solve for [tex]r[/tex], the cost of one ruler.

[tex]50 \times 0.5 + 30\, r = 55[/tex].

[tex]30\, r = 55 - 25 = 30[/tex].

[tex]r = 1[/tex].

In other words, the cost of one ruler would be [tex]\$ 1[/tex].

Explanation: Well in my opinion.... Your networth doesn't matter its just showing how much money you spent...

Soo if you had $4 Million you'd pay it automatically.

Answer:

x = -11/3, y = -4/3

Step-by-step explanation:

[tex]y-2x=6\\y = 2x + 6[/tex]

[tex]3(2x + 6) = -4\\6x + 18 = -4\\6x = -22\\x = -11/3[/tex]

[tex]3y = -4\\y = -4/3[/tex]

Answer:

I think it is 9

Step-by-step explanation:

Answer:

The answer is 9

Step-by-step explanation:

15 * [tex]\frac{4}{5}[/tex] * [tex]\frac{3}{4}[/tex] = 15 * [tex]\frac{3}{5}[/tex] = 9

Answer:

the answer is D

Step-by-step explanation:

Answer:

the answer is 1/2 or 0.5

Step-by-step explanation:

So basically you just get on a calculator and divide it after you do that it will give you a decimal and all you have to do is convert that decimal to a fractiom so we know that 0.5 is a half so therefore 0.5=1/4

Answer:

C

Step-by-step explanation:

When looking at the total cost of x pounds of something when the cost is per pound, you multiply the two numbers. Because y is the total cost, you want that as the answer that you are looking for, so it will be by itself when looking at the two sides of the equation. This means that answer c is the only one correct. A/B cannot be unless you were looking for the number of pounds, and you were dividing y (total cost) by 2.19 (cost per pound). D does not work because you are just adding how many pounds you have to the cost per pound.

Answer:

The group of students on the top right those students have a mean of 2.6

Step-by-step explanation:

The mean is adding up all the different numbers of pets for each kid and dividing it by the number of kids so 13 the number of pets and 5 the number of different students

Answer:

5)9x+8y=-2

-5x+8y=26

A) (2,2)

Based on your image, I will assume u meant: [tex]|2x+4| \leq 6[/tex]

This means that x will have two solution sets, due to the absolute value.

[tex]-5\leq x\leq 1[/tex]
