g(a)=a-2
f(a)=2a+2
find g(a)•f(a)

Answer:

x = - 3

Step-by-step explanation:

To find the zero, let f(x) = 0, that is

4x + 12 = 0 ( subtract 12 from both sides )

4x = - 12 ( divide both sides by 4 )

x = - 3 ← is the zero

Step-by-step explanation:

Your question isn't well written but I guess you meant that 0.75gb was shared at first. This means that the father and mother will share:

= 6 - 0.75

= 5.25

Therefore, each of them will use:

= 5.25 / 2

= 2.625gb

Answer:

The two equations represented by the graph is -x+1=1 and y-2=4

Step-by-step explanation:

The reasoning behind this is that the slope move upward with the x equation and downward with the y. :)

tHE FACT THAT YOU GUYS ACTUALLY THOUGHT THIS WAS THE RIGHT ANSWERRRRR LOLOL SMH

Answer:

456.25m

Step-by-step explanation:

Since the question did not ask for what to find, we can as well look for the maximum height reached by the object

Given the height of an object thrown vertically expressed as;

s=-16t^2+100t+200.

At max height,

dS/dt = 0

-32t+100 = 0

-32t = -100

t = 100/32

t = 3.125s

Get the Max height

s(3.125) = -16(3.125)²+100(3.125)+200

s(3.125) = -156.25+312.5+200

s(3.125) = 456.25m

Hence the maximum height reached by the object is 456.25m

Step-by-step explanation:

[1/2]^-2= 4

[1/3]^-2=9

[1/4]^-2=16

So sum is 4+9+16=29

Hope this helps you.

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).

Answer:

Deal 2

Step-by-step explanation:

Deal 2, has an average of about

$20 for 5 miles,

$45 for 15 miles,

$60 for 20 miles.

Deal 1 has a higher rate cost for 15 and 20 miles than Deal 2. So Deal 2 has a lower cost of rate with makes it more optional.

Answer:

30

Step-by-step explanation:

15/3=5

5 x 5 = 25

25 + 5 = 30

Answer:

C

Step-by-step explanation:

Given

5² + (x ÷ 3) ← substitute x = 15 into the expression

= 25 + (15 ÷ 3)

= 25 + 5

= 30 → C

Answer:

5x=15

Step-by-step explanation:

Product means multiplication, and 5x=15 is the only one doing multiplication

Answer:

The required line is will be:

The graph of the line y = 4/5x is attached below.

Step-by-step explanation:

We know that when y varies directly with x, we get the equation

y ∝ x

y = kx

k = y/x

where k is called the 'constant of variation'.

It is also clear that 'constant of variation' basically represents the slope m or rate of change, with the lines passing through the origin, so

given

k = 4/5

substitute k = 4/5 in the equation y = kx

y = kx

y = 4/5x

Therefore, the required line is will be:

The graph of the line y = 4/5x is attached below.

Answer:

-(7 x^2 - 3 x - 5) thus A.

Step-by-step explanation:

Simplify the following:

-(4 x^2 - 2 x) - 3 x^2 + x + 5

Hint: | Factor common terms out of 4 x^2 - 2 x.

Factor 2 x out of 4 x^2 - 2 x:

-3 x^2 + x + 5 - 2 x (2 x - 1)

Hint: | Distribute -2 x over 2 x - 1.

-2 x (2 x - 1) = 2 x - 4 x^2:

2 x - 4 x^2 - 3 x^2 + x + 5

Hint: | Group like terms in -3 x^2 - 4 x^2 + 2 x + x + 5.

Grouping like terms, -3 x^2 - 4 x^2 + 2 x + x + 5 = (-3 x^2 - 4 x^2) + (x + 2 x) + 5:

(-3 x^2 - 4 x^2) + (x + 2 x) + 5

Hint: | Combine like terms in -3 x^2 - 4 x^2.

-3 x^2 - 4 x^2 = -7 x^2:

-7 x^2 + (x + 2 x) + 5

Hint: | Add like terms in x + 2 x.

x + 2 x = 3 x:

-7 x^2 + 3 x + 5

Hint: | Factor a minus sign out of -7 x^2 + 3 x + 5.

Factor -1 out of -7 x^2 + 3 x + 5:

Answer:  -(7 x^2 - 3 x - 5)

The answer is d > 20

Answer:

3x + 4y = - 20

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 )

Here m = - [tex]\frac{3}{4}[/tex] , thus

y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation

To find c substitute (- 8,  1) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = - [tex]\frac{3}{4}[/tex] x - 5 ← in slope- intercept form

Multiply through by 4 to clear the fraction

4y = - 3x - 20 ( add 3x to both sides )

3x + 4y = - 20 ← in standard form

Answer:

6x-23

Step-by-step explanation:

6(x+4)+1

=(6x)+(24+1)

=6x+25
