Two numbers have a sum of 18. Their product is 72. Find the numbers

Answers

Answer 1

Answer:

Step-by-step explanation:

x + y = 18

y = 18 - x

xy = 72

x(18 - x) = 72

-x² + 18x = 72

0 = 72 - 18x + x²

x = (18 ± √(18² - 4(1)(72))) / (2(1))

x = (18 ± 6)/2

x = 12

x = 6

Geometry ….. solve for x and y

Answers

Answer:

y = 2.4

x = 30°

Step-by-step explanation:

5y = 12

[tex]\frac{5y}{5}[/tex]  = [tex]\frac{12}{5}[/tex]

Cancel both the 5 in numerator and denominator

y = [tex]\frac{12}{5}[/tex]

Divide 12 by 5

y = 2.4

All internal angles of a triangle must add up to 180°. So the angles of the bottom triangle is 60° each. As you can see, there's a right triangle on the right side and a right angle is 90°. So you just have to subtract 90° and 60° to get the angle of the missing angle which is 30°

x = 30°

i don't know how to explain it but i'm sure it's correct. Hope it helps

(5, -2); slope =-1 please help I need answers asap

Answers

Answer:

y = - x + 3

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (5, - 2 ) into the partial equation

- 2 = - 5 + c ⇒ c = - 2 + 5 = 3

y = - x + 3 ← equation of line

Solve by factoring 12x^3+12x^2=0

Answers

Factor out the GCF
12x^2(x + 1) = 0
Now you can do two parts
12x^2 = 0, x = 0
x + 1 = 0, x = -1

Solution: x = 0, x = -1

Factor out the GCF

12x^2(x + 1) = 0

Now you can do two parts

12x^2 = 0, x = 0

x + 1 = 0, x = -1

Solution: x = 0, x = -1

What is the slope of the line that
passes through the points (-1, 3)
and (2, 10)?

Answers

Answer:

D  [tex]\frac{7}{3}[/tex]

Step-by-step explanation:

For find the slope of whatever line we use the next formula:

[tex]m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So in our occasion we have:

[tex]y_2 = 10 \quad \text{and} \quad y_1 = 3\\x_2 = 2 \quad \text{and} \quad x_1 = -1[/tex]

Replacing in the equation:

[tex]\frac{10 - 3}{2 - (-1)} = \frac{7}{3}[/tex]

So the answer is [tex]\frac{7}{3}[/tex]

Find the lines of symmetry. Select all that apply. Thank you!

Answers

Lines r & t are the lines of symmetry here.

◇ The line r cuts the figure vertically into 2 equal halves.

◇ The line t cuts the figure horizontally into 2 equal halves.

◇ The lines q & s don't cut the figure symmetrically (2 unequal parts are formed), so they are not the lines of symmetry.

The answer is sides are congruent by the reflexive property

Step-by-step explanation:

The answer is sides are congruent by the reflexive property because the two red lines on the triangles represnt that they are congruent. The reason teh fourth one can be a correct answer, but it is not, is because the angles are not vertical. The angles would hav eto be in teh middle of the triangle and congruent, to be right. So it is a reflexive property.
