P.S. (from k12)

[tex] \begin{cases} x - y = - 2 \\ 4x - y = 4 \end{cases}[/tex]

Simply multiply the negative one in one of the equations.

[tex] \begin{cases} - x + y = 2 \\ 4x - y = 4 \end{cases}[/tex]

We can finally eliminate the y-term by adding both equations.

[tex]( - x + 4x) + (y - y) = 2 + 4 \\ 3x + 0 = 6 \\ 3x = 6 \\ x = \frac{ 6 }{3} \longrightarrow \frac{ \cancel{6}}{ \cancel{3}} = 2 \\ x = 2[/tex]

[tex]x - y = - 2 \\ 2 - y = - 2 \\ 2 + 2 = y \\ 4 = y[/tex]

First Equation

[tex]x - y = - 2 \\ 2 - 4 = - 2 \\ - 2 = - 2 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]

Second Equation

[tex]4x - y = 4 \\ 4(2) - 4 = 4 \\ 8 - 4 = 4 \\ 4 = 4 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]

Hence, the solution is (2,4).

[tex] \begin{cases} x = 2 \\ y = 4 \end{cases}[/tex]

Answer:

(10, -8)

Step-by-step explanation:

Answer:

solution given:

G(x1,y1)=(-2,2)

H(x2,y2)=(x,y)

Mid point M(a,b)=(4,-3)

we have

(a,b)=((x1+x2)/2,(y1+y2)/2)

(4,-3)=((-2+x)/2,(2+y)/2)

comparing corresponding value

4=(-2+x)/2

8+2=x

x=10

again

(2+y)/2=-3

2+y=-6

y=-6-2

y=-8

So coordinates of H is (10,-8).

Answer:

87.5%

Step-by-step explanation:

There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.

The number is students not trying out for football last Thursday is calculated as:

376 students - 47 students

= 329 students

The percent of 8th graders that did not try out for football is calculated as:

329 students/376 students × 100

= 329/376 × 100

= 87.5 %

Answer:

first 4 terms =7,10,13,16

10th term = 34

Step-by-step explanation:

3n+4

3(1)+4=7

3(2)+4=10

3(3)+4=13

3(4)+4=16

7,10,13,16

10th term = 3(10)+4= 34

The first four terms of the sequence having nth term 3n+4, are 7, 10, 13, 16 and the 10th term is 34.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

Given that,

The nth term of a sequence is given by 3n+4,

To find the first 4 terms, substitute the values of n,

At n=1, the first term = 3(1) + 4 = 3 + 4 = 7

At n=2, the second term = 3(2)+4 = 6 + 4 = 10

At n=3, the third term = 3(3) + 4 = 9 + 4 = 13

At n=4, the fourth term = 3(4) + 4 = 12 + 4 = 16

For 10th term, substitute n=10.

At n=10, the tenth term = 3(10) + 4 = 30 + 4 = 34

The first four terms are 7, 10, 13, 16 and the 10th term is 34.

Answer:

Pretty sure its 256 in2

Step-by-step explanation:

did the iready test

By decomposing the design into two rectangular prisms, the surface area of the design is calculated as: A. 256 in.²

The surface area of a rectangular prism is expressed as, S = 2(lw + lh + wh).

The design can be decomposed into top rectangular prism and bottom rectangular prism.

The surface area of the design = surface area of the top rectangular prism + surface area of the bottom rectangular prism - 2(area of the top rectangular prism that joins the bottom rectangular prism)

Surface area of the top rectangular prism = 2(lw + lh + wh) = 2(5×4 + 5×4 + 4×4) = 112 in.²

Surface area of the bottom rectangular prism = 2(lw + lh + wh) = 2(8×5 + 8×4 + 5×4) = 184 in.²

Area of the top rectangular prism that joins the bottom rectangular prism = l × w = 5 × 4 = 20 in.²

The surface area of the design = 112 + 184 - 2(20) = 256 in.²
