Which is an equation of the function graphed?

Answer:

A

Step-by-step explanation:

We have -4x > -10, so 4x < 10

Answer:

A. x < 2.5

Step-by-step explanation:

you subtract 5 on both sides

then you get -4x > -10.

then you divide -4 on both sides

and you get x<2.5

Answer:

1) Option 3

2) Option 3

3) Option 3

4) Option 1

5) Option 2

6) Option 3

7) Option 1

Step-by-step explanation:

1) [tex]y = x^2 + 4x + 3[/tex]

Lets split the middle term.

[tex]=> y = x^2 + 3x + x + 3[/tex]

[tex]=> y = x(x+3) + 1(x + 3)[/tex]

[tex]=> y = (x+1)(x+3)[/tex]

∴ [tex]x = -3 , -1[/tex]

2) [tex]y = 8x^2 - 22x + 5[/tex]

Lets split the middle term.

[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]

[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]

[tex]=> y = (2x - 5)(4x - 1)[/tex]

∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]

3) [tex]y = x^2 - 5x[/tex]

[tex]=> y = x(x - 5)[/tex]

∴ [tex]x = 0 , 5[/tex]

4) [tex]y = 12x^2 + 18x[/tex]

[tex]=> y = 6x(2x + 3)[/tex]

∴ [tex]x = \frac{-3}{2} , 0[/tex]

5) [tex]y = x^2 - 7x + 12[/tex]

Lets split the middle term.

[tex]=> y = x^2 -3x - 4x + 12[/tex]

[tex]=> y = x(x - 3) - 4(x - 3)[/tex]

[tex]=> y = (x - 3)(x - 4)[/tex]

∴ [tex]x = 3,4[/tex]

6) [tex]y = 3x^2 + 10x + 8[/tex]

Lets split the middle term.

[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]

[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]

[tex]=> y = (x + 2)(3x + 4)[/tex]

∴ [tex]x = -2 , \frac{-4}{3}[/tex]

7) [tex]y = x^2 - 4x - 45[/tex]

Lets split the middle term.

[tex]=> y = x^2 - 9x + 5x - 45[/tex]

[tex]=> y = x(x - 9) + 5(x - 9)[/tex]

[tex]=> y = (x - 9)(x + 5)[/tex]

∴ [tex]x = -5 , 9[/tex]

Answer:

3 adult tickets and 4 child tickets were bought.

Answer:

4 adult tickets and 3 child tickets

Step-by-step explanation:

So doing 234/7 gives you 33.428... which means its not all just children or adults. (I know that's common sense but it's best to do this anyway to further justify your answer)

The total cost for all 7 people shows that there must be an even amount of adult tickets to end up with a whole number so either 2, 4, or 6 adults.

2 adults = $75

4 adults = $150

6 adults = $225

Now we can use these possibilities to figure out if the left over child tickets added to the adult tickets would equal $234. (quick note: I am using # to show that it doesn't equal $234)

If 2 adults = $75, 5 children = $140, $140+$75 = $215 # $234

If 4 adults = £150, 3 children = $84, $84+$150 = $234

Now because we have already figured out that it would be 4 adult tickets and 3 child tickets, we wouldn't need to figure out 6 adult tickets and 1 child ticket, but, again, this would justify your answer and help to secure your marks.

If 6 adults = $225, 1 child = 28, $28+$225 = $253 # $234

I hope this answer helped you out and if you have any questions I'd be happy to help :)

THANK YOU

Answer:

Step-by-step explanation:

The rate of change, m, is defined as

m=(y2-y1)/(x2-x1), in this case we have points (-15,-3) and (-7,-1) so

m=(-1+3)/(-7+15)

m=2/8

m=1/4

Answer:

c) x=1.23

Step-by-step explanation:

a =3

b=2

c=-7

use quadratic equation where

[tex] { ax}^{2} + bx + c = 0 = \frac{ - b \: + or \: - \sqrt{ {b} ^{2} - 4ac} }{2a} [/tex]

-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3

square root of (2^2-(4×3×-7) )

= 9.38083152

2×3=6

-2+or - 9.38 all that divided by 6

-2+9.38= 7.38÷6

x=1.23

or

-2-9.38 all divided by 6

-2-9.38= -11.38 ÷6

x= -1.9

all in all x can't be negative meaning x=1.23

Answer:

6x = - 21

Step-by-step explanation:

Given

3x - 7 = 5x ( subtract 3x from both sides )

- 7 = 2x

Then

6x = 3 × 2x = 3 × - 7 = - 21

Answer:

5(4x + 3y) = 20x + 15y

Step-by-step explanation:

The matter of months in which in this case is 5 months is the coefficient.

The amount of boxes per month is important information. We don't know how many bars are in each box. EACH is a key word for multiplying. If we want to know quickly how many bars are in 4 boxes (or 3) of the granola bars. We can simply multiply the amount of bars for each box with the amount of boxes. Since we don't know the amount  of bars there are in each box we are going to use a variable. so it would look like this- 4x + 3y BUT we need to add the coefficient. Now rewrite the expression. 5(4x + 3y)

We can use the distributive property to generate an equal expression.

Answer:

Step-by-step explanation:

V = π times r^2 times h (height)

452.16 = 3.14 times r^2 times 4

Multiply 3.14 times 4

452.16 = 12.56 times r^2

Divide 452.16 by 12.56.

452.16 / 12.56 = 36

36 = r^2

The square root of 36 is 6.

So the radius of the cylinder is 6 yards^3.

Step-by-step explanation:

Answer:

f(1) = -4

Step-by-step explanation:

Given that,

f(x) = 2x-6

We need to find the value of f(1).

Put x = 1 in the above expression.

f(1) = 2(1)-6

= 2-6

= -4

So, the value of f(1) is equal to -4.

Answer:

y = 1/2 x + 5

Step-by-step explanation:

slope (m) = (y'-y) / (x'-x)

(y-6)/(x-2) = 1/2

y - 6 = 1/2 x - 1

y = 1/2 x + 5

Answer:

c. -13 + 2g is the correct option.

Answer:

x = 13.6 in

Step-by-step explanation:

The arc x is calculated as

x = circumference of circle × fraction of circle

   = 2πr × [tex]\frac{0.8}{2\pi }[/tex] ( cancel the 2π on numerator/ denominator )

   = 17 × 0.8

   = 13.6 in

Answer:

e = 129

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

e is an exterior angle of the triangle , then

e = 60 + 69 = 129
