The first answer and the last one

Plug in each number into their designated spots.
Example with (0,5)

0 goes into x and 5 goes into the y variable and this is the equation now:

2*0 +4*5=20

0 times 2 = 0 and 4*5=20
So that is one of the correct answers.

Repeat the process and you find that the last option is also correct.

How do you solve 3/5×4 1/6?
Helen [10]
\frac{3}{5} × 4 \frac{1}{6}

First, convert 4\frac{1}{6} to an improper fraction. Use this rule: a \frac{b}{c} = \frac{ac+b}{c} / Your problem should look like: \frac{3}{5} × \frac{4x6+1}{6}
Second, simplify 4 × 6 to 24. / Your problem should look like: \frac{3}{5} × \frac{24+1}{6} 
Third, simplify 24 + 1 to 25. / Your problem should look like: \frac{3}{5} × \frac{25}{6}
Fourth, apply this rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd} / Your problem should look like: \frac{3x25}{5x6}
Fifth, simplify 3 × 25 to 75. / Your problem should look like: \frac{75}{5x6}
Sixth, simplify 5 × 6 to 30. / Your problem should look like: \frac{75}{30}
Seventh, simplify. / Your problem should look like: \frac{5}{2}
Eighth, convert to mixed fraction. / Your problem should look like: 2\frac{1}{2}

Answer: 2 \frac{1}{2}

9. Consider the function f(x) = x² + 3x – 4.
BaLLatris [955]

Answer:

  c.  f(x) = (x + 4)(x - 1)

Step-by-step explanation:

Since you're familiar with the product of two binomials:

  (x +a)(x +b) = x² + (a+b)x + ab

you know that the constants in the binomial factors must ...

  • have a product of -4
  • have a sum of +3

__

All of the choices except B have binomial constants that have a product of -4.

In order, the sums of the remaining choices are ...

  A: 1-4 = -3

  C: 4-1 = 3 . . . . this is the correct choice

  D: -2+2 = 0

The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3year
Paha777 [63]

Answer:

Step-by-step explanation:

The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3years and 4months at 18% per annum.Find the sum​

The formula for Simple Interest = PRT

From above question, we have to find the Principal

The simple interest on a certain sum for 5years at 8% per annum is Rs200

Hence,

R = 8%

T = 5 years

Rs 200 = P × 8% × 5

P = 200/8% × 5

P = Rs500

The principal = Rs 500

The simple interest on the same sum for 3years and 4months at 18% per annum.

Simple Interest = PRT

R = 18%

T = 3 years and 4 months

Converted to years

T = 3 + (4 months/12 months)

T = 3.33 years

Hence,

Simple Interest = Rs 500 × 18% × 3.33 years

= Rs 299.7
