In each of the two right triangles, one angle measure is two times another angle measure. Can you determine that the triangles a

Elis [28]

Answer:

Two triangles are similar if and only if the corresponding sides are in proportion and the corresponding angles are congruent. To show two triangles are similar, it is sufficient to show that two angles of one triangle are congruent (equal) to two angles of the other triangle.

the function f is defined by f(x)=150/x-z where z is a constant. find z if the value of f at x=1/5 is equal to 250

malfutka [58]

Answer:

x = -1 $\frac{1}{20}$

Step-by-step explanation:

f( $\frac{1}{5}$ ) = 120, therefore we can create this equation:

120 = 150 ÷ ( $\frac{1}{5}$ - z)

cross-multiply to get: 24 - 120z = 150

-120z = 126

z = -1 $\frac{3}{60}$

Answer:

$x=-1$

Step-by-step explanation:

STEP 1: Factor x ^2 − 8 x + 12 using the AC method.

$\frac{4}{(x-6)(x-2)} =\frac{x}{x-2} +\frac{1}{x-6}$

STEP 2: Find the LCD of the terms in the equation.

$(x-6)(x-2)$

STEP 3: Multiply each term by ( x − 6 ) ( x − 2 ) and simplify.

$4=x^2-5x-2$

STEP 4: Solve the equation.

$x=6,-1$

STEP 5: Figure out the answer.

$x=-1$

Find the coordinates of a point that divides the directed line segment PQ in the ratio 5:3. A) (2, 2) B) (4, 1) C) (–6, 6) D) (4

Yuri [45]

Answer:

The answer is explained below

Step-by-step explanation:

The question is not complete we need point P and point Q.

let us assume P is at (3,1) and Q is at (-2,4)

To find the coordinate of the point that divides a line segment PQ with point P at $(x_1,y_1)$ and point Q at $(x_2,y_2)$ in the proportion a:b, we use the formula:

$x-coordinate:\\\frac{a}{a+b}(x_2-x_1)+x_1 \\\\While \ for\ y-coordinate:\\\frac{a}{a+b}(y_2-y_1)+y_1$

line segment PQ is divided in the ratio 5:3 let us assume P is at (3,1) and Q is at (-2,4). Therefore:

$x-coordinate:\\\frac{5}{5+3}(-2-3)+3 \\\\While \ for\ y-coordinate:\\\frac{5}{5+3}(4-1)+1$
