Answer:

your answer simplified is:

13+3i

Step-by-step explanation:

2x - 3y = 9

2x + 3y = 3

__________ -

-6y = 6

y = -1

2x - 3y = 9

2x - 3(-1) = 9

2x - (-3) = 9

2x = 12

x = 6

Answer:

Step-by-step explanation:

Answer:

x=11

Step-by-step explanation:

since the triangle is an isosceles triangle, angle 2 should be angle 42 so,

2x+20=42 degrees

2x=22

x=11

Answer:

Step-by-step explanation:

find all of tehe factors to both numbers

15x = 5 3 x

35 = 5 7

pull 5 out of both of them and put the remaining factors in parentheses

5(3x + 7)

Answer:

I don't have a car T-T

Step-by-step explanation:

Answer: The answer is: -2

Step-by-step explanation:

Here, suppose

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

(-7,22)=(x2, y2)

Now, use the slope equation to find slope(m).

     y2-y1=m(x2-x1)

or,m=y2-y1/x2-x1

After this, just substitute the values from above.

Answer:

C. Magma pushed up from the mantle to sedimentary rocks which

then eroded leaving the column.

Step-by-step explanation:

Geologists Carpenter and Russell studied Devils Tower in the late 1800s and concluded that the Tower was formed by an igneous intrusion (the forcible entry of magma through other rock layers).

Answer:

  ? = 95°

Step-by-step explanation:

Long arc QR is twice the measure of inscribed angle QSR, so is 2×95° = 190°. That, together with the remaining short arcs ? and RS will make up the total circle of 360°.

  arc QR + arc RS + ? = 360°

  190° +75° +? = 360°

  ? = 360° -265° . . . . . . subtract 265° from both sides

  ? = 95°

Step-by-step explanation:

you need to mulitiply the 4 to x and -3

4x-12

if you need to solve for x: 4x=12

X=3

The answer is 4x-12

if you multiply 4 times x it is 4x, and if you multiply 4 by negative 3(-3) the answer is negative 12 (-12), so you put 4x together with -12 that would be 4x-12

The function  [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.

Thus, option (D) is correct.

As, Domain is the input value of the function.

In the function [tex]y= -x^{1/2}+5[/tex] .

The square root is defined for all non-negative real numbers (including zero).

When we subtract this square root from 5, the resulting function has a domain of all real numbers.

In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.

The function can be evaluated for any real number x, making its domain all real numbers.

Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.

Answer:

g=7

Step-by-step explanation:

your goal is to isolate the g

times g/-4 by -4/1 the -4 cancels out the other one so you are just left with g

move the g to the other side of the equation then move the 3 and it to the -5 and then multiply the whole thing but -1 to make the equation positive

Answer:

we have:

u(1) = 18

u(2) = 21 = 18 + 3

u(3) = 24 = 18 + 3.2

u(4) = 27 = 18 + 3.3

.......

=> the sequence has: u(1) = 18

                                    d = 3

=> u(n) = 18 + 3(n - 1) = 3n + 15

so the recursive formula for the sequence is u(n) = 3n + 15

Answer:

1,760 actual miles separate Springfield from Glenview.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.

The map has the scale:

0.75 inch => 220 miles

This gives us the scaling factor as 220/0.75. There is no need to divide.

We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is

6*220/0.75 = 1,760

1,760 actual miles separate Springfield from Glenview.

Answer:153

Step-by-step explanation:

From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.

If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:

= 3/25 × 1280

= 153.6

There will be 153 students expected

Answer: D) x - 0.2x

Step-by-step explanation:

The hat has a regular price of x dollars.

This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x

The discounted price will be the price of the hat less the discount which means the formula will be;

= Price - discount

= x - 0.2x
