Answer:

(x-2)^2+(y+4)^2=34

Answer:

x^2 +3x -54

Step-by-step explanation:

Use the method FOIL

(First, Outer, Inner, Last)

1. Multiply the 1st terms in bracket 1 and the 1st term in bracket 2:

(x × x)

2. Multiply the 1st term in bracket 1 and the 2nd term in bracket 2:

(x × 9)

3. Multiply the 2nd term in bracket 1 and the 1st term in bracket 2:

(-6 × x)

4. Multiply the 2nd term in bracket 1 and the 2nd term in bracket 2:

(-6 × 9)

5. You'll get the answer:

(x^2 + 9x - 6x - 54)

(x^2 + 3x -54)

Answer:

2

Explanation:

In short terms, there are two numbers that are reciprocals of themselves, 1 and -1.  According to euler's identity, e^(-i*2*pi) is a reciprocal of itself, but I believe that is beyond the scope of this question.

Step-by-step explanation:

3x² + 22x + 35 = 0

(3x + 7)(x + 5) = 0

3x + 7 = 0

x = -7/3

or x+5 = 0

x = -5

Answer:  You should solve by equal method not substitution.  y=7     x=2

Step-by-step explanation: Equal value method is when two things equal each other and in this case both 3x+1 and 5x-3 equal y so they also equal each other.   3x+1=5x-3                  add 3 to each sides

                      3x+4=5x                     subtract 3x from each side

                      4=2x                           divide by 2

                        x=2                                                             solve for y=3x+1

                                                                                                           y=3(2)+1

                                                                                                          y=7

Answer:

30% are children.

Step-by-step explanation:

Females = 30%

Males = 40%

Therefore, children = 100% (total) - 30% + 40%

100 - 70

30%

in a city 30 °/• are female and 40°/. are males . what are remaining children?

Given,

▶️ percentage of females = 30%

▶️ percentage of males = 40%

▶️ let the percentage of children be x.

Now,

▶️ x = 100% (total population) - 30% + 40%

▶️ x = 100% - 70%

▶️ x = 30% (Children population)

The population % of children in a city is 30%.

Answer:

d=5/3x

Step-by-step explanation:

Let's solve for d.

(2/3x)(d)=10/9

Step 1: Divide both sides by (2x)/3.

2/3dx / 2x/3=10/9 / 2x/3

d=5/3x

Step-by-step explanation:

Answer:

Step-by-step explanation:

Graph A. is too low and graph C. is too steep.

Also we know that 3/2 is equal to 1.5. This means that it will be a little more than y = x. So if we look at point (2,2), the line is not at that point, but the line is a little higher.

Answer:

x = 45 degrees

Step-by-step explanation:

Opposite adjacent angles are congruent

160 - x = 115

x = 45

Answer:

For the first one your first point is going to be on (0, -8) and will be a continuous horizontal line.

For the second equation the first point will be on (0, -12)

you want to go down two points and go to the right once point so (1, -14), (2,-16), (3,-18)

you also want to go up two points and to the left once so (-1, -10), (-2, -8), (-3, -6) and so on

Step-by-step explanation:

The domain of the graph is,

''All integers less than or equal to 6''.

Option C is true.

What is Domain of graph?

Domain of a graph consists of all the input values shown on the x - axis.

The graph of a function is shown in figure.

Now, The graph is defined on the value less than 6 on the x -axis.

And, The domain of a graph consists of all the input values shown on the x - axis.

Thus, The domain of the graph is,

''All integers less than or equal to 6''.
