Write a linear function f with the
values f(0) = 6 and f(4) = -6.
Answer:
f(x) = -3x + 6
Step-by-step explanation:
The general linear function is;
y = mx + b
it can also be written as (x , f(x))
f(x) = mx + b
where m is the slope and b is the y-intercept
so we have the points ;
(0,6) and (4,-6)
So we have;
for f(0) to be 6, it means that the y-intercept b is 6
This is because the value of x at the y-intercept is 0
So we have this as;
f(x) = mx + 6
Now, let’s substitute the other point so as to get m
For the other point;
x = 4 and f(x) = -6
that means;
-6 = 4m + 6
4m = -6-6
4m = -12
m = -12/4
m = -3
So we have the equation as;
f(x) = -3x + 6

Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{3}{c}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
c = 3[tex]\sqrt{2}[/tex]
One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45
Answer:
x=60, y= 60
x=100, y= 20
x=40, y=80
Step-by-step explanation:
Triangles add up to 180 degrees. The ones above added to 60 equal 180.
60+60+60=180
100+20+60=180
40+80+60=180
Hope this helps! :)
in AABC, the measure of angle A=x degree, the measure of angle B=(2x)degrees, and the measure of angle C=(6x+18)degrees. What is the measure of angle B?
Answer:
m<B: 36
Step-by-step explanation:
x + 2x + 6x + 18 = 180
9x + 18 = 180
9x = 162
x = 18
m<B:
2x
2(18)
36
Answer:
m<B=36°
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
That means the sum of m<A+m<B+m<C=180°
We're given that:
m<A=x°
m<B=(2x)°
m<C=(6x+18)°
we can substitute those values as m<A, m<B, and m<C
x+2x+6x+18=180
combine like terms
9x+18=180
subtract 18 from both sides
9x=162
divide by 9
x=18°
we found the value of x, but we're not done yet
The question asks to find m<B, which is 2x°
in that case, we can substitute our known value to find the measure of <B
m<B=2x°
m<B=2(18)°
m<B=36°
Write an expression for the amount that Elaine earns per day.
A.32+d
B.32d
C.32/d
Answer:
B. 32d
Step-by-step explanation:
B. 32d
If Elaine earns $32 per day, 32 would act as how much she earns a day and 'd' would act as how many days she has worked.
E.g. Elaine worked 6 days. 32*6 = $192
find the exact value of x.
Answer:
x = 4 sqrt(3)
Step-by-step explanation:
x is not to be confused by the mark on the right angle -- X
The function is the cosine of Y which is 30 degrees.
The cosine of 30o is sqrt(3)/2
cos(30) = adjacent side / hypotenuse = sqrt(3) / 2
The adjacent side is 6
cos(30) = 6/ x = sqrt(3) / 2
6/x = sqrt(3) / 2 Cross multiply
x * sqrt(3) = 6 * 2
x * sqrt(3) = 12 divide by sqrt(3)
x = 12 / sqrt(3) Multiply top and bottom by sqrt(3)
x = 12* sqrt(3) / sqrt(3) * sqrt(3)
x = 12 sqrt(3)/ 3 Divide by 3
x = 4 sqrt(3)

The average color of the population would become paler would living in White Sands National Monument for a few generations change a population of eastern fence lizards. Hence, option C is correct.
What Is White Sands National Monument worth visiting?It's difficult to travel to White Sands National Park, and there aren't many things around to keep you very busy. It's a peaceful area with peculiar traits and uncommon lifeforms. Not everyone can benefit from it, but some of us can. If you go, sand will likely go in your eyes as well as your boots.
Plan to spend a whole day in White Sands National Park for the finest experience. Early in the morning, before the tourists gather and the warmth rises, hike the Alkali Flat Trail. Have a picnic lunch and go sledding on the dunes around noon. One of the shorter hiking trails is another option.
Thus, option C is correct.

Answer:
We have to find the value of x.
We need to substitute with 3 because they measure the same.
Step-by-step explanation:
(x - 1)
x - 1 = 3
x - 1 + 1 = 3 + 1
x = 4
(x + 1)
x + 1 = 5
x + 1 - 1 = 5 - 1
x = 4
Both answers are the same which means that they are correct.

Can anyone help? 110 degrees ,41 degrees , 40 degrees, x?
Answer:
11°
Step-by-step explanation:
This is hard to explain because they don't have names lol
So looking at the larger main triangle...
the top angle is composed of two angles measuring 40° and 41°. So it is equal to 81°.
The angle on the lower left side is a supplimentary angle with the one that measures 110°. The two of them combined make a line. A straight line is 180°, so that angle is 70°. (180 - 110)
The final angle in the triangle is accross from x. This makes them a pair of vertical angles, so therefore congruent.
The angles of a triangle add up to 180°
We already know the other two angles so 180 - 81 - 70 = 11°
so x is also 11°

Gary draws this sequence of patterns of white and grey squares. The sequence is continued. How many grey squares will there be with 16 white squares?
Answer:
20 gray squares
Step-by-step explanation:
Given
See attachment for squares
Required
Number of gray squares when white = 16
First, we calculate the equation that represents both squares.
The white squares
[tex]a = 2[/tex] --- initial
[tex]d = 4 - 2 = 6 - 4[/tex]
[tex]d = 2[/tex] -- difference between successive gray squares
So, the nth term is:
[tex]W_n = a + (n - 1)d[/tex]
[tex]W_n = 2 + (n - 1)*2[/tex]
[tex]W_n = 2 + 2n - 2[/tex]
[tex]W_n = 2n[/tex]
The gray squares
[tex]a = 6[/tex] --- initial
[tex]d = 8-6=10-8[/tex]
[tex]d = 2[/tex] -- difference between successive gray squares
So, the nth term is:
[tex]G_n = a + (n - 1)d[/tex]
[tex]G_n = 6 + (n - 1) *2[/tex]
[tex]G_n = 6 + 2n - 2[/tex]
[tex]G_n = 4 + 2n[/tex]
When the white squares is 16
[tex]W_n = 16[/tex] --- Calculate n
[tex]W_n = 2n[/tex]
[tex]16 = 2n[/tex]
[tex]8 = n[/tex]
[tex]n = 8[/tex]
To get the number of gray squares;
Substitute [tex]n = 8[/tex] in [tex]G_n = 4 + 2n[/tex]
[tex]G_n = 4 + 2 * 8[/tex]
[tex]G_n = 20[/tex]
