Find the variable. m angle BDJ=7y+2 , m angle JDR=2y+7
Anna35 [415]

The value of the variable y is 9 given that BDJ=7y+2  and angle JDR=2y+7

From the attached diagram, we can see that the<u> sum of m<BDJ and m<JDR is complementary</u> (i.e. sums up to 90degrees)

Given the following

m<BDJ = 7y + 2

m<JDR = 2y + 7

Summing up to 90

m<BDJ + m<JDR = 90

7y + 2 + 2y + 7 = 90

7y+2y+2+7 = 90

9y + 9 = 90

9y = 90-9

9y = 81

y = 81/9

y = 9

Hence the value of the variable y is 9

There are four cards numbered 1 through 4. The number 2 card is chosen randomly and not replaced. Find the probability of choosi
malfutka [58]

Answer:

1/3

Step-by-step explanation:

since number 2 card was not replaced, we have;

probability of picking a second card, 3;

let S be number of sample space

n(S)= 4

n(3)= 1

Pr(3/2)= 1/3

(because since one was already chosen and n, the sample space would reduce)

The vertex is the minimum point of the graph of the quadratic equation.

Let's first find the like of symmetry.

dy/dx=2x+12

2x+12=0

2x=-12

x=-6

Now plug -6 into the quadratic equation

y=(-6)²+12(-6)+32

y=-4
