➷ Substitute it into the equation:

3 = 2x + 5

Subtract 5 from both sides:

-2 = 2x

Divide both sides by 2:

x = -1

The other coordinate is -1

Answer:

-1

Step-by-step explanation:

<u>1</u><u>.</u>We know that the equation of the line is <u>y=2x+5</u> ( with a gradient of 2 and a

y-intercept of 5) and the y coordinate is 3 so we must work out x (x,3).

<u>2.</u>We know<u> y=3</u> so

3 = 2x+5

 

<u>3.</u> <u>Solve the equation</u>

3=2x+5

(-5 from both sides)

-2=2x

(Divide both sides by 2 to isolate x)

-1 = x so x = 1

Hope this helps:)

Suppose a birth defect has a recessive form of inheritance. In a study population, the recessive gene (a) initially has a preval
BabaBlast [244]

Answer:

Step-by-step explanation:

a) Maternal gene = 0.25; Paternal gene = 0.25

Probability having a birth defect = 0.25 X 0.25 = 0.625

b) P(A) = 0.30; P(B) = 0.70

P(A)*P(B) = 0.30 X 0.70 = 0.021

For marriage:

25%: P(A)*P(A)*0.25 = 0.09 X 0.25 = 0.0225

65%: P(B)*P(B)*0.65 = 0.049 X 0.65 = 0.03185

10%: P(A)*0.10 = 0.03 and P(B)*0.10 = 0.07

P(A)*P(B) = 0.03 X 0.07 = 0.0021

Probability of a defect birth in the next generation = 0.0225 + 0.03185 + 0.0021 = 0.05645

c) 1. P(A)*P(A) = 0.09

2. P(B)*P(B) = 0.049

3. P(A)*P(B) = 0.021

the answer would be negative, since the parachutist is descending. so 158 × 17 = 2,686

make that negative.
