Answer:

y, because ΔABC is similar to ΔEDC

Step-by-step explanation:

∠B= ∠D = 65 {Given}

∠ACB = ∠ECD {Vetically opposite angles}

Therefore, ∠E = ∠A

∠E = y

Answer:

8) v = 312

9) s = -12/13

Step-by-step explanation:

8) Multiply left and right by -14, then you get

v-18 = -21*-14

v-18 = 294

Add 18 left and right:

v = 294 + 18

v = 312

9) Add 26 left and right

-13s = -14 + 26

-13s = 12

Divide left and right by -13

s = -12/13

if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?

umka2103 [35]

Answer:

$(p - q)(x) = (x -1) (x - 4)$

Step-by-step explanation:

Given

$p(x) = x^2 - 1$

$q(x) = 5(x - 1)$

Required

(p - q)(x)

This is represented as:

$(p - q)(x) = p(x) - q(x)$

$(p - q)(x) = x^2 - 1 - 5(x - 1)$

$(p - q)(x) = x^2 - 1 - 5x + 5$

Collec like terms

$(p - q)(x) = x^2 - 5x + 5 - 1$

$(p - q)(x) = x^2 - 5x + 4$

Expand

$(p - q)(x) = x^2 -4x - x + 4$

Factorize

$(p - q)(x) = x(x -4) - 1(x - 4)$

$(p - q)(x) = (x -1) (x - 4)$

Use a scientific calculator to find the antilogarithm of each logarithm rounded to four decimal places.

attashe74 [19]

Assuming you're working in base 10, then the antilog of 3.493 is equal to 10^3.493 = 3,111.71633710601

This rounds to 3111.7163 so the answer is choice D
