Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]

x= [tex]\frac{-2}{5}y-2[/tex]

2-  3x+y+−y=66+−y

3x=−y+66

[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]

[tex]x=\frac{-1}{3}y+22[/tex]

Answer:

300

Step-by-step explanation:

3 :  15 :: 60 : x

Product of extremes  = Product of  means

3 * x = 15 * 60

    [tex]x = \frac{15 * 60}{3}\\\\x = 5*60\\\\x = 300[/tex]

Or Do in this way

[tex]\frac{3}{15}=\frac{60}{x}\\\\[/tex]

[tex]\frac{3*20}{15*20}=\frac{60}{x}[/tex]

x = 15* 20 = 300

wait holy gosh dude is this about the congruence stuff? I think I can help!

ok so triangle RST is very similar to triangle ABC BECAUSE triangle RST is just dialated and or turned around it also has the lines so it must be similar or closest to 1.5 for each sides

srry if this is wrong if it is plz correct me nicely in the comments lol

19 cm

The diagonals of the bases form a rectangle with sides containing A and B points.

AB is the diagonal of the formed rectangle and its length is:

[tex]\tt AB = \sqrt{5^2 + 16^2+7^2 } = \sqrt{25 + 256+49 } = \sqrt{369} } = 19 cm [/tex]

Answer:

y = -0.5x + 3

Step-by-step explanation:

The equation of a linear model is generally represented as;

y = mx + b

where m

is slope and b is the y-intercept

We can get slope by using the slope equation

m =

(y2-y1)/(x2-x1)

(x1,y1) = (-4,5)

(x2,y2) = (4,1)

m = (1-5)/(4 + 4) = -4/8 = -0.5

The equation is thus;

y = -0.5x + b

to get b, we substitute any of the two points coordinates

1 = -0.5(4) + c

1 = -2 + c

c = 2 + 1

c = 3

Answer:

B. x^2x2 and 2x^22x2

Step-by-step explanation:

The expression given is:

8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2

Like terms are terms in which their variables and the power of the variables (exponents) are the same.

While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.

In that case, the like terms in the expression given are x^2x2 and 2x^22x2 .

Note: The question says 8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2 but the option has -4x^2−4x2 .

In case its actually -4x^2−4x2 instead of -4x^3−4x3 , then,

 -4x^2−4x2 is also a like term and the answer will be D.

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution

Answer:

135.71 sea otters

Step-by-step explanation:

y = 70(1.18)^4

y = 70 x 1.9387

y = 135.71

The number of sea otters after 4 years with an exponential growth of 18% will be 135.71.

A connection of the form y = ax, where x is an independent variable that spans the entire real number line and is written as the exponent of a positive number, is known as an exponential function in mathematics.

The exponential growth function is given as,

y = C x^n

y = 70(1.18)⁴

y = 70 × 1.9387

y = 135.71

Hence "After 4 years, there will be 135.71 sea otters, representing an exponential growth of 18%".

Answer: 18.8 miles

Step-by-step explanation:

Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:

4.7x = 2.5x + 8.8

Collect like terms.

4.7x - 2.5x = 8.8

2.2x.= 8.8

x = 8.8/2.2

x = 4

To know how fast the kickers are going will be

4.7x = 4.7 × 4 = 18.8 miles

Answer:

B

Step-by-step explanation:

Reflect x-axis means (x,y) becomes (x, -y)

Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x

Up 4 units means f(x) = x becomes f(x)= x + 4

So lets put that together

[tex]f(x) = \sqrt{x}[/tex]

[tex]f(x) = -\sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]
