Answer:

3 + 4 > 9

Step-by-step explanation:

Now, when we have 3 sides of a triangle, the sum of the length of any two sides must be greater than the third side

Thus, we have that;

3 + 4 > 9

This is because the above is impossible

Others are quite possible mathematical expressions

Amount needed by her [tex]=\$(5x+5)[/tex]

Step-by-step explanation:

Given: Susie wants to buy 5 slices of pizza and a litre of soda that cost $5 for her and her friends

To find: amount needed by her

Solution:

Let cost of 1 slice of pizza be [tex]\$x[/tex]. Also, a litre of soda costs $5.

Cost of 5 slices of pizza [tex]=\$5x[/tex]

Cost of a litre of soda [tex]=\$5[/tex]

Total amount needed by her [tex]=\$(5x+5)[/tex]

Step-by-step explanation:

The formula for slope is y2-y1 over x2-x1.

Answer:

y+3=1/2(x-4)

Step-by-step explanation:

any line parallel to another line has the exact same slope. So you already know your slope, but to do this, we need point slope form. y-y_1=m(x-x_1). we can plug in the slope as well as well as the point that we know. y+3=1/2(x-4). Remeber, math is all about being simple. since the question didn't specify a certain form of the equation, you can just keep this as your answer! Hope this helped!

a(-5,-2)

Step-by-step explanation:

The midpoint of a segment

Given points C(xc,yc) and B(xb,yb), the coordinates of the midpoint M can be found knowing that:

[tex]\overline{CM} = \overline{ MB}[/tex]

Applying that relation in both axes separately, we can write:

[tex]\displaystyle x_m=\frac{xc+xb}{2}[/tex]

[tex]\displaystyle y_m=\frac{yc+yb}{2}[/tex]

Knowing the coordinates of the midpoint and B, we can find the coordinates of the other extreme C solving both equations for the required variable:

[tex]x_c=2x_m-x_b[/tex]

[tex]y_c=2y_m-y_b[/tex]

Plugging in the known values: M=(-1,1) and B=(3,4):

[tex]x_c=2*(-1)-3=-2-3=-5[/tex]

[tex]y_c=2*1-4 = 2-4=-2[/tex]

The coordinates of C are (-5,-2)

Step-by-step explanation:

The required simplified value of the given function at f(6) = 36.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
Given function
f(x) = 4x + 12

Put x = 6
f(6) = 4(6) + 12
f(6) = 24 + 12
f(6) = 36

Thus, the required simplified value of the given function at f(6) = 36.

======================================================

Explanation:

Recall that vertex form is

y = a(x-h)^2 + k

where (h,k) is the vertex. We want the vertex to be (-3,0) which means that h = -3 and k = 0 must be the case.

Plug those values in to get

y = a(x-h)^2 + k

y = a(x-(-3))^2 + 0

y = a(x+3)^2

Now we need the value of 'a', which determines two things

To determine 'a', we'll use the other point (-5,-4).

So we'll plug in x = -5 and y = -4 and solve for 'a'

y = a(x+3)^2

-4 = a(-5+3)^2

-4 = a(-2)^2

-4 = a(4)

-4 = 4a

4a = -4

a = -4/4

a = -1

The equation y = a(x+3)^2 updates to y = -1(x+3)^2 which simplifies to the final answer y = -(x+3)^2. The answer is choice D.

---------------

As a check, plugging x = -5 should lead to y = -4

y = -(x+3)^2

y = -(-5+3)^2

y = -(-2)^2

y = -(4)

y = -4

This helps confirm the answer.

I'll let you check to see if (-3,0) is on this graph. Plugging in x = -3 should lead to y = 0.

Answer:

3. 4a(a + 1) - 15

step-by-step explanation:

1. (x +y)² + 11 (x + y) + 30

= x + y {(x +y) + 11} + 30

2. (a - b)² - 16(a - b) + 60

= (a - b){(a - b) - 16} + 60

3. 4a² + 4a - 15) - 15

4. 2x² + 5x + 2

= x(2x + 5) + 2

Answer:

It takes about 30 minutes to kayak 1 mile on flat calm water.

Step-by-step explanation:

The required simplified solution of the given expression is 16c/[25 - c²].

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given expression,
= 8 / 5 - c - 8 / 5 + c
= 8 [5  + c - 5 + c] / [5² - c²]
= 8 / [25 - c²] × 2c

Answer:

39 MPH

Step-by-step explanation:

       d  =  rt

13 times 3,

20x3=60.

60=1 hour

13M = every 20m

60 divided by 20 =3.

13 times 3 = 39.

39MPH

Kayla is driving at 39 miles per hour.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.

Given:

Kayla drove 13 miles in 20 minutes.

To find the average rate in miles per hour:

Miles / hour

= 1 / 1

Multiply by 3 to the rate,

So, 13 x 3 mils in 3 x 20 minutes.

39 miles per hour.

Therefore, the average rate is at 39mph.
