(1) In the diagram below, AC || DF|| BH || and CB || FE.

Liula [17]

Answer:

Part 1) Triangles ABC, DBG, DEF and BEH are similar

Part 2) $\frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}$

Step-by-step explanation:

Part 1)

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In this problem Triangles ABC, DBG, DEF and BEH are similar, because its corresponding angles are congruent by AA Similarity Theorem

Part 2)

Remember that

If two triangles are similar, then the ratio of its corresponding sides is equal

therefore

$\frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}$

Determine all values of h and k for which the system S 1 -3x - 3y = h -4x + ky = 10 has no solution. k= ht

Lana71 [14]

Answer:

$h\neq 7.5$

k = -4

Step-by-step explanation:

Given system of equations are,

-3x-3y = h

-4x + ky = 10

We have to find the values of h and k such that system of equations has no solution.

The standard form of system of equation in two variables can be given by,

$a_1x+b_1y+c_1=0$

$a_2x+b_2y+c_2=0$

And condition for the system of equations has no solution is given by,

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}$

So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,

$\dfrac{-3}{-4}=\dfrac{-3}{k}\neq \dfrac{h}{10}$

$=>\dfrac{-3}{-4}=\dfrac{-3}{k}$

=> k = -4

and $\dfrac{-3}{-4}\neq \dfrac{h}{10}$

$=>\ \dfrac{-3\times 10}{-4}\neq h$

$=>\ h\neq \dfrac{30}{4}$

$=>\ h\neq 7.5$

So, the value of h and k for above given system of equations is

$h\neq 7.5$ and k = -4.

Write and solve an inequality that means a number plus six is less than or equal to twenty-four.

hichkok12 [17]

Answer:

Inequality: x + 6 ≤ 24

Solution: x ≤ 18

Step-by-step explanation:

Plus: "+" → to add something to something else

Less than or equal to: "≤" → the expression on the left side of the inequality sign is smaller than the expression on the right side of the sign.

Let x be the unknown number.

A number plus 6 is less than or equal to twenty-four:

x + 6 ≤ 24

To solve the found inequality, subtract 6 from both sides:

⇒ x + 6 - 6 ≤ 24 - 6

⇒ x ≤ 18

Therefore, the solution to the inequality is x ≤ 18. The unknown number x can be any real number equal to or less than 18.

Find the complex factors of the quadratic trinomial x^2+8x+17

3241004551 [841]

Answer:

[x+(4-i)][x+(4+i)]

Step-by-step explanation:

Complete the square then regroup the first two terms. Add and subtract: (b/2)^2=(8/2)^2=16

x^2+8x+17=(x^2+8x)+17

=(x^2+8x+16)+17-16

=(x+4)^2+1 create a difference of squares using i^2= -1

=(x+4)^2 - (-1)

=(x+4)^2 - i^2 use the difference of two squares identity

=[(x+4) - i][(x+4)+i]

=[x+(4-i)][x+(4+i)]
