Answer:

  6, 9

Step-by-step explanation:

Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...

  2x -3 = 15 -x . . . . . three less than twice one number is the other number

  3x = 18 . . . . . . add 3+x

  x = 6 . . . . . . divide by 3

  15-x = 9 . . . . find the other number

The two numbers are 6 and 9.

Can someone please please please help.?
Luden [163]

Answer:

<h2>43°</h2>

Step-by-step explanation:

In a cyclic quadrilateral, the sum of two opposite angles are equal.

m<R + m<P = 180°

plugging the values:

3y + 8 + y = 180°

Combine the like terms:

4y + 8 = 180°

Subtract 8 on both sides

4y + 8 - 8 = 180 - 8

Calculate the difference

4y = 172

divide both sides of the equation by 4

4y/4 = 172/4

calculate

y = 43°

Hope this helps...

Which equation, in slope-intercept form, passes through (–2, 4) and has a
kipiarov [429]

Answer:

y=3x+10

Step-by-step explanation:

First, put the equation into point-slope form.

y-y1=m(x-x1)

y-4=3(x+2)

Next, distribute 3 to (x+2) and simplify.

y-4=3x+6

y=3x+10

Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).
DochEvi [55]

Let y=ab^x, as described in the problem statement. Plugging in x=2 and x=5 gives us the equations 18=ab^2 and 60.75=ab^5. Since a,b are nonzero, we divide the second equation by the first to get \frac{27}{8}=b^3, which means that b=\frac{3}{2}, after taking the cube root. Plugging this value for b into the first equation, we now have 18=a(3/2)^2=\frac{9a}{4}. Solving gives a=8, and our desired exponential equation is \boxed{y=8\left(\frac{3}{2}\right)^x}.

What can you say about the quotient, when you divide 23 by something equal to 1?
Gwar [14]

Answer: the quotient will be equal to 23

The equation to calculate what divided by 23 equals 1 is as follows:

X/23 = 1

Where X is the answer. When we solve the equation by multiplying each side by 23, you get get:

X = 23

Therefore, the answer to what divided by 23 equals 1 is 23

so the quotient will be equal to 23
