CAN YOU PLZZZZZZZZZ HELP ME WITH THIS

Answer:

Infinitely many solutions.

Step-by-step explanation:

Multiply the second equation by -2, then add the equations together

(20x+2y=18)

−2(10x+y=9)  

20x+2y=18

−20x−2y=−18

Add these equations to eliminate x

0=0

Infinitely many solutions.

Answer:

[tex]\vec v = 2\cdot \vec a = \langle -4,6 \rangle[/tex]

Step-by-step explanation:

Let [tex]\vec a = \langle -2, 3 \rangle[/tex], we need to determine [tex]\vec v = 2\cdot \vec a[/tex], which can be found by applying the following property:

[tex]\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle[/tex], [tex]\forall \,\alpha,x,y\in \mathbb{R}[/tex] (1)

Then,

[tex]\vec v = 2\cdot \langle -2,3 \rangle[/tex]

[tex]\vec v = \langle -4,6 \rangle[/tex]

Answer:

the percentage change in the volume of the oil is -3.22%

Step-by-step explanation:

The computation of the percentage change in the volume of the oil is given below:

= -(6,000 - 0) ÷ (186,000)

=  -3.22%

This negative sign represents the decrease in the volume

Hence, the percentage change in the volume of the oil is -3.22%

Answer:

Alternate Interior ∠s: 3 & 5, 4 & 6.

Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.

Alternate Exterior ∠s: 1 & 8, 2 & 7.

Consecutive ∠s: 3 & 6, 4 & 5.

Step-by-step explanation:

Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.

Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.

Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.

Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.

Good luck.

Answer:

side= 6400/4

       =1600

therefore the area= 1600*1600

                                2560000

cost of reaping 100sq.m.=35

cost of reaping 1sq.m= 0.35

cost of reaping 2560000m sq=  2560000*0.35

                                                    = 906000

Answer:

(-2, -1, 0, 3,3)

Step-by-step explanation:

The domain simply refers to the possible x-values the function can take

so by listing out all the x-values of the individual points, we have all the domains

That will be ;

(-2, -1, 0, 3,3)

Answer:

x = 5

y = -3

as an ordered pair: (5,-3)

Step-by-step explanation:

if y = -3, then replace y in the first equation with -3.

-3 - 3x = 12

move -3 over to the other side by adding 3 to both sides.

3x = 15

x = 5

y = -3

Answer:

x = -5

y = -3

Step-by-step explanation:

Two equations

Solve using substitutition

y = -3

y - 3x = 12

_____________________

Since the first equation has y alone, we can plug it into the second equation for y.

(-3) - 3x = 12

-3 - 3x = 12

Add 3 to both sides :

-3x = 15

Divide -3 from both sides to get x alone :

x = -5

Now that we have x, plug it into x in the second equation :

y - 3(-5) = 12

y + 15 = 12

Solve for y :

Subtract 15 from both sides :

y = -3

Answer:

27.2 ft

Step-by-step explanation:

Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.

So, to get from 1 to 8, we multiply by 8.

And since we multiply by 8, we also have to do it to the other part as well.

So we would do:

8 x 3.4 = 27.2

Hope this helps! :)

Answer:

-35

Step-by-step explanation:

X's cancel out each other

-10+-25

Answer:

5.5

Step-by-step explanation:

2x -3 = 8

then

2x = 8 + 3 = 11

means

2x = 11

then

x = 11 ÷ 2

x = 5.5

___________________

we change the sign (- or +)

then take the number to the other side of the equal (with the changed sign)

leaving the x alone so that we can answer the equation..

Answer:

[tex]y-1=6(x+5)[/tex]

Step-by-step explanation:

The given point is (-5, 1) and the slope is 6.

Point-slope form is given by:

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

We will let (-5, 1) be (x₁, y₁) and we will substitute 6 for m. Therefore:

[tex]y-(1)=6(x-(-5))[/tex]

Simplify:

[tex]y-1=6(x+5)[/tex]

Answer:

6 students.

Step-by-step explanation:

3v +  c = 22  ---> c = 22 - 3v

2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28

                         2v + 88 - 12v = 28

                       -10v + 88 = 28

                               - 88  - 88

                        - 10v = - 60

                              v = 6 students

Answer:

See the distances bellow

Step-by-step explanation:

Given data

D(-5, -6), E(5, 2)

substitute into the expression for the distance

[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((5+5)^2 + (2+6)^2)\\\\d= \sqrt((10)^2 + (8)^2)\\\\d= \sqrt(100 +64)\\\\d= \sqrt((164)\\\\d= 12.80[/tex]

E(5, 2), F(4, -4)

[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((4-5)^2 + (-4-2)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08[/tex]

F(4, -4), G(-6, -12)

[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6-4)^2 + (-12+4)^2)\\\\d= \sqrt((-10)^2 + (-8)^2)\\\\d= \sqrt(100+64)\\\\d= \sqrt((164)\\\\d= 12.80[/tex]

G(-6, -12),  D(-5, -6)

[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6+5)^2 + (-12+6)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08[/tex]

Step-by-step explanation:

f(x) = —x^2 – 3x

f(10)={-10}²-3×10=100-30=70

Answer:

f(10) = 70

Step-by-step explanation:

In this question, plug in "10" to "x" and solve.

Solve:

f(10) = -(10)^2 - 3(10)

f(10) = 100 - 3(10)

f(10) = 100 - 30

f(10) = 70

Your final answer would be f(10) = 70
