F(x) = –x^2+ 6 Find f(-3)

Lynna [10]

So if f(-3), then x = -3.

Substitute.

y = -(-3)^2 + 6

= -(9) + 6

= -3

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your way home, you travel at an average r

kenny6666 [7]

Answer:

14 miles

Explanation:

The relation that will be used to solve this problem is:

$Distance = Velocity*Time$

which can be rewritten as:

$Time = \frac{Distance}{Velocity}$

Assume that:

Distance from your house to your friend's house is d

Time taken from your house to your friend's house is t₁

Time taken from your friends house to your house is t₂

1- From your house to your friend's house:

Average rate = 35 miles/hour

Therefore:

$t_{1} = \frac{d}{35}$

2- From your friend's house to your house:

Average rate = 40 miles per hour

Therefore:

$t_{2} = \frac{d}{40}$

3- Round trip:

We know that the round trip took 45 minutes which is equivalent to 0.75 hours

This means that:

t₁ + t₂ = 0.75 hours

$\frac{d}{35}+\frac{d}{40}=0.75\\ \\\frac{40d + 35d}{1400}=0.75\\ \\\frac{75d}{1400}=0.75\\ \\ 1050 = 75d\\ d=14 miles$

Hope this helps :)

What is the y-intercept of the line 3x-4y=24

Contact [7]

Answer:

(0,-6)

Step-by-step explanation:

3x-4y=24

To find the y intercept, let x =0 and solve for y

3(0) -4y =24

-4y =24

Divide by -4

-4y/-4 = 24/-4

y = -6

The y intercept is

(0,-6)

Line segment st is dilated to create line segment s't' using the dilation rule dq,2.25. point q is the center of dilation. line

astra-53 [7]

The value of x when the line segment st is dilated to create line s't' about point q is 2.5 units

<h3>How to determine the value of x?</h3>

The given parameters are:

qs = 2

qt = 1.2

tt' = 1.5

ss' = x

To calculate the value of x, we make use of the following equivalent ratio

ss' : qs = tt' : qt

So, we have:

x : 2 = 1.5 : 1.2

Express as fractions

x/2 = 1.5/1.2

Multiply both sides by 2

x = 2 * 1.5/1.2

Evaluate the product

x = 2.5

Hence, the value of x is 2.5 units
