Answer:

y=-4x^2+24x-32

Step-by-step explanation:

let f(x)=a(x-4)(x-2)

f(3)=a(-1)(1)=4

so a=-4

Answer:

Step-by-step explanation:

(- 18) × 2 = - 36

(- 7) × (- 5} = 35

1 × (- 10) = - 10

126 × 100 = 12600

Answer:

y = - [tex]\frac{9}{5}[/tex] x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

9x + 35 = - 5y ( add 5y to both sides )

5y + 9x + 35 = 0 ( subtract 9x + 35 from both sides )

5y = - 9x - 35 ( divide all terms by 5 )

y = - [tex]\frac{9}{5}[/tex] x - 7 ← in slope- intercept form

Answer:

Step-by-step explanation:

Use identity : (a + b)²  =a² + 2ab + b²

49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²

                                  = (7m²)² + 2 *7m²*10 + 10²

                                   = (7m² + 10)²

                                   = (7m² + 10)(7m² + 10)

Your answer would be 108

HCF(324, 432, 540) = 108

b (?) and c

m and n have the same slope (-2/5) so m//n

Step-by-step explanation:

they expect originally to put 12 songs on the CD.

are you sure about the 2% ? is that not 20% ? or better 25%.

because

100% = 12

1% = 100%/100 = 12/100 = 0.12

2% = 1%×2 = 0.12×2 = 0.24

"0.24 songs more" does not really make any sense.

20% would then be 2.4 songs, which would mean 2 songs, but 2 would be only 2/0.12=16.7%.

but 25% would be 0.12×25 = 3. so, 3 songs more.

and that makes sense.

so, they produced 25% or 3 songs more than they expected to put on the CD. that is 12+3=15 songs.

now, we have a new 100% :

100% = 15

1% = 15/100 = 0.15

40% = 0.15×40 = 6

so, 6 songs are removed.

that leaves 9 songs on the CD.

Answer:

Length: 18cm

Width: 6cm

Step-by-step explanation:

1. make sure that the length in the width are 12 cm apart. that leaves options a, c, and d.

2. multiply the length by 2 and the width by 2 and then add those two answers together. if it equals 48 then that is the right answer.

Answer:

No solution

Step by Step Explaination:

Answer:

No solutions

Step-by-step explanation:

5(x - 3) = 7x - 2(x + 1)

5x - 15 = 7x - 2x - 2

5x - 15 = 5x - 2

-15 = -2 (not true so it’s no solution)

Answer:

258

Step-by-step explanation:

Check the tenth place. It is 4 which is < 5. So, ignore and write the whole number as it is

So, 258.42 = 258

Answer:

0.15

Step-by-step explanation:

We can divide both sides to single out the x:

x = [tex]\frac{3.75}{25}[/tex]

Simplifying that gives:

x = 0.15

Answer: I believe the answer is: x=15

Step-by-step explanation: 15*.25=3.75

This plotted as a graph is as shown in option B

Answer:

A) y = 3x + 2 y = -2x + 5

Step-by-step explanation:

We can rule out options B and D right away, because one of the lines' y-intercept is positive 2 not negative.

(Remember that y-intercept is the b in y=mx+b).

So at this point we know the answer is either A or C.

We can also rule out C though, because the second line's y-intercept is positive 5, while the second line in option C is negative.

You can also use the slope of each line to double check.

Hope this helps :)
