Answer:

x

−4x+4=0

To solve the equation, factor x

−4x+4 using formula x

+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=−4

ab=4

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 4.

−1,−4

−2,−2

Calculate the sum for each pair.

−1−4=−5

−2−2=−4

The solution is the pair that gives sum −4.

a=−2

b=−2

Rewrite factored expression (x+a)(x+b) using the obtained values.

(x−2)(x−2)

Rewrite as a binomial square.

(x−2)

To find equation solution, solve x−2=0.

Solve the following equation:
1.3(a + 2) + 5.6 = 17.3

Answers

Answer:

a=7

Step by step Explanation:

Step 1: Simplify both sides of the equation.

1.3(a+2)+5.6=17.3

(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)

1.3a+2.6+5.6=17.3

(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)

1.3a+8.2=17.3

1.3a+8.2=17.3

Step 2: Subtract 8.2 from both sides.

1.3a+8.2−8.2=17.3−8.2

1.3a=9.1

Step 3: Divide both sides by 1.3.

1.3a      9.1

1.3     =   1.3

a = 7

 

Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.40 plus $4.50 per mile. The total fare was $87.90, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.

Answers

Answer:

a = 6, b = - 12

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms to those on the right side.

a(4x - 10) ← distribute parenthesis

= 4ax - 10a

Compare to 24x + 5b , then

4a = 24 ( divide both sides by 4 )

a = 6

Then

5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )

b = - 12

Kieran picks a bead out of a bag without looking.He records the colour and replaces the bead.Kieran does this 50 times.He picks out a red bead 15 times. Estimate the probability of picking a red bead.

Answers

Answer: 3/10

Step-by-step explanation:

From the question, we are informed that Kieran picks a bead out of a bag without looking and that he records the colour and replaces the bead.

He does this 50 times and he picks out a red bead 15 times. The probability of picking a red bead will be the number of times a red bead was picked divided by the number of title times a bead was picked. This will be:

= 15/50

= 3/10
