(9x-6)

Answer:

Yes, Always

Step-by-step explanation:

If M is the midpoint of line KL, then M, K, and L are collinear.

As you notice in the diagram, to be collinear means part of the same line.

Answer:

(x-1)  (x+8)

Step-by-step explanation:

Use the sum-product pattern:

x^2+7x-8

x^2+8x-x-8

Common factor from the two pairs:

x^2+8x-x-8

x(x+8)-1(x+8)

Rewrite in factored form:

x(x+8)-1(x+8)

Solution:

(x-1) (x+8)

Answer:

When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution.

Answer:

[tex]3.84\times10^8\ m[/tex]

Step-by-step explanation:

It is given that,

The average distance between the Earth and the Moon is 384 400 km.

We need to express in in standard form.

1 km = 1000 m

It means,

384400 km = 384400000 km

or

= [tex]3.84\times10^8\ m[/tex]

Hence, the average distance between the Earth and the Moon is [tex]3.84\times10^8\ m[/tex].

Answer:

yes

Step-by-step explanation:

heres why

Step 1: Add 5 to both sides.

7y−5+5=9+5

7y=14

then ima divide 14 by 7 which equals 2

14/7y =2

so its true

(0,7) , (7,8)

Y-intercept is at (0,7) and the slope is 1/7 so from the y intercept, go up 1 and over 7.

Step-by-step explanation:

Answer:

f(x)=-1/4x-2

Step-by-step explanation:

m=-3-(-2)/4-0=-1/4= slope

b=y-intercept=-2,

so f(x)=-1/4x-2

A linear function f with f(4)=−3 and f(0)=−2 is

[tex]f(x)=-\frac{1}{4}x-2[/tex]

Given :

a linear function f with f(4)=−3 and f(0)=−2.

f(0)=-2. It means y intercept is -2

Linear equation of a line is given by y=mx+b

where m is the slope and b is the y intercept

y intercept b is -2

Lets find out slope m . Lets use f(4)=-3  that is when x=4 the value of y is -3

[tex]y=mx+b\\y=mx-2\\x=4, y=-3\\-3=m(4)-2\\-3+2=4m\\-1=4m\\m=-\frac{1}{4}[/tex]

Now we replace in the equation of line y=mx+b

[tex]y=mx+b\\y=-\frac{1}{4}x-2[/tex]

Replace y with f(x) to get linear function

[tex]f(x)=-\frac{1}{4}x-2[/tex]

Answer:

The histogram shows the heights in meters of trees in a certain section of a park.  

How many trees are less than 20 meters tall?

Answer: From the given histogram, we clearly see:

There is 1 tree with height less than 8 meters

There are 1 + 2 = 3 trees with height less than 12 meters

There are 3 + 2 = 5 trees with height less than 16 meters

There are 5 + 4 =9 trees with height less than 20 meters.

Therefore, the correct option is B. 9

Answer:

around 66% of their games

Step-by-step explanation:

So if we add 20 and 10 we get 30 which is the total amount of games played. We know that the team won 20 of the 30 games which we can reduce to 2/3. 2/3 is equal to 66.66 but most people just say 66% or you can round it up to 67%

Hope I helped!

Answer:

30/t = 18/r

30 = 18t/r

30r = 18t

18t = 30r

18t/18 = 30r/18

t = 5/3r

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

30/t = 18/r

30r = 18t/r

30r = 18t

30r/30 = 18t/30

r = 3/5 t

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

r = 3/5t, t = 5/3r

Answer:

Step-by-step explanation:

The set up will give a right angles triangle;

Given

The height of the ramp (opposite) = 6 foot

distance away along the ground = 40 feet (adjacent)

Required

Angle of depression theta

Using the TOA identity;

tan theta = opposite/adjacent

tan theta = 6/40

tan theta = 0.15

theta = tan^-1{0.15}

theta =8.53 degrees

hence the angle of depression to nearest tenth of a degree is 89.5 degrees

Answer:

4.5 hours

Step-by-step explanation:

Given that Gian lives 45 miles east of Salina where Zach lives.

At the same time, both start driving in the same direction towards the east, Zach drives 65 miles per hour and Gina drives 55 miles per hour.

Let A and B are the initial locations of Zach and Gina respectively, after t hours they meet at point C which x miles east of point B as shown in the figure.

Distance traveled by Gina = BC= x miles

As distance = speed x time, so

[tex]x= 55 \times t \cdots(i)[/tex]

Similarly, distance traveled by Gina = AC= (45+x) miles

As distance = speed x time, so

[tex]45+x= 65 \times t \\\\[/tex]

[tex]\Rightarrow 45+55t= 65 \times t[/tex] [ using equation (i)]

[tex]\Rightarrow 10t= 45 \\\\[/tex]

[tex]\Rightarrow t = 45/10 = 4.5[/tex] hour

Hence, the required time is 4.5 hours.

Answer:

The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

Step-by-step explanation:

Given

[tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex]

We know the rational zeros theorem such as:

if [tex]x=c[/tex] is a zero of the function [tex]f(x)[/tex],

then [tex]f(c) = 0[/tex].

As the [tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex] is a polynomial of degree [tex]4[/tex], hence it can not have more than [tex]4[/tex] real zeros.

Let us put certain values in the function,

[tex]f(5) = 448[/tex], [tex]f(4) = 126[/tex], [tex]f(3) = 0[/tex], [tex]f(2) = -20[/tex],

[tex]f(1) = 0[/tex], [tex]f(0) = 18[/tex], [tex]f(-1) = 16[/tex], [tex]f(-2) = 0[/tex], [tex]f(-3) = 0[/tex]

From the above calculation results, we determined that [tex]4[/tex] zeros as

[tex]x = -3, -2, 1,[/tex] and [tex]3[/tex].

Hence, we can check that

[tex]f(x) = (x+3)(x+2)(x-1)(x-3)[/tex]

Observe that,

[tex]for x > 3[/tex], [tex]f(x)[/tex] increases rapidly, so there will be no zeros for [tex]x>3[/tex].

Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.
