Find x 1,) 2 2.) 4 3.) 1/2 4.) 1/4

1 answer:

5 0

Because sides PQ and RQ are congruent, then angles P and R are also congruent. So 3x+1=7x-1

Once you solve the answer should be x=2

F(x)=1/x; Find f(1/2)

alukav5142 [94]

Answer:

Step-by-step explanation:

f(x) = 1 / x

f(1/2) = 1 / (1/2)

Reciprocal of 1/2 is 2, since you flip numerator and denominator:

f(1/2) = 2

Find 5 consecutive whole numbers if it is known that the sum of the squares of the first 3 numbers is equal to the sum of the sq

zlopas [31]

Let numbers be x-1,x,x+1,x+2,x+3

(x-1)^2 + x^2 + (x+1)^2 = (x+2)^2 + (x+3)^2

$( x^{2} -2*x+1)+ x^{2} +( x^{2} +2*x+1)= ( x^{2} +4x+4)+( x^{2} +6x+9)
$
$3 x^{2} +2=2 x^{2} +10x+13⇒
 x^{2} =10x+11⇒
 x^{2} -10x-11=0
$

x=11 or -1(not a whole number)
x=11
the numbers are 10,11,12,13,14

If m∠13=2x-3 and m∠15=71°, find the value of x.<br> Show work please

sineoko [7]

<h3>The value of x is 37</h3>

Here ∠13 & ∠15 are corresponding angles , so they are equal [ ∠13 = ∠15 ]

As per the question ,

⇒ 2x - 3 = 71°

⇒ 2x = 71 + 3

⇒ 2x = 74

⇒ x = 74 ÷ 2

⇒ x = 37

Hence , x = 37
