Answer:

There are 10 dogs in the kennels

Step-by-step explanation:

The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.

Which means, if [tex]n_d[/tex] the number of dods and [tex]n_c[/tex] is the number of cats, then,

[tex]\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)[/tex]

Given that there are 20 cats, so [tex]n_c=20.[/tex]

Now, from equation (i) we have,

[tex]\frac {n_d}{20}=\frac{1}{2}[/tex]

[tex]\Rightarrow n_d=\frac{1}{2}\times 20[/tex]

[tex]\Rightarrow n_d= 10[/tex].

Hence, there are 10 dogs in the kennels.

Answer:

[tex]A.) 25[/tex]

Step-by-step explanation:

[tex]f(3)[/tex] means that the value of x is 3. Insert this into the equation for x, but DO NOT insert the value into f(x). To not get confused, remember that f(x) is basically y. You can insert y into the equation to not get mixed up:

[tex]f(x)=(3)^3-2\\\\or\\\\y=3^3-2[/tex]

Now simplify the equation, starting with exponents (PEMDAS):

[tex]x^3=x*x*x\\\\3*3*3\\\\9*3=27\\\\f(x)=27-2\\\\or\\\\y=27-2[/tex]

Simplify subtraction:

[tex]27-2=25\\\\f(x)=25\\\\or\\\\y=25[/tex]

:Done

Answer:

No Solutions

Step-by-step explanation:

If you simplify the equation, you would get 30x + 30 = 30x + 40, which if you subtract 30x, you would get 30 = 40, which means that there are no solutions, because no amount for x would balance this equation.

Step-by-step explanation:

Step 1: Define systems

x - 2y = 6

y = 11 - 3x

Step 2: Rewrite systems

x = 2y + 6

y = 11 - 3x

Step 3: Solve for y

Step 4: Solve for x

Answer:

x=4  y=-1

Step-by-step explanation:

x-2(11-3x)=6

x-22+6x=6

7x-22=6

7x=22+6

x=28/7

x=4

The graph for the given slope of 8 and includes the point (0,2) is given below.

Given that, the line that has a slope of 8 and includes the point (0,2).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Substitute m=8 and (x,y)=(0, 2) in y=mx+c, we get

2=8(0)+c

c=2

Put m=8 and c=2 in y=mx+c, we get

y=8x+2

Graph the line using the slope and y-intercept, or two points.

Slope: 8

y-intercept: (0,2)

Coordinate points are (0, 2) and (1, 10)

Hence, the graph for the given slope of 8 and includes the point (0,2) is given below.

Answer:

Up left, down right

Step-by-step explanation:

First, polynomials with odd degrees will have end behaviors in two different directions.

Since the leading coefficient is negative, the end behavior will be up left and down right.

So, the end behavior is up left, down right.

The end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

We have to determine

The end behavior of a 9th-degree polynomial with a negative leading coefficient??

If the leading coefficient is negative and the exponent of the leading term is even, the graph falls to the left and right.

The equation of the 9th-degree polynomial is;

[tex]\rm x^9+3x^8+4x^7+x^6+x^5+9x^3+2x^2+x+1=0[/tex]

The degree of the polynomial is 9 which is odd.

Hence, the end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

For the two lines A and B to be parallel to each other, the value of x should be equal to 20.

In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc.

The definition of corresponding angles states that when two parallel lines cross with a third, the angles that occupy the same relative location at each junction are said to be corresponding angles to each other.

As per the given diagram of the parallel lines and the transverse the measure of the angle 2 and angle 5 should be equal, This is because the two angles are corresponding angles. Therefore, we can write,

∠2 = ∠5

3x - 20 = x + 20

3x - x = 20 + 20

2x = 40

x = 20

Hence, for the two lines A and B to be parallel to each other, the value of x should be equal to 20.
