Answer:
y = -x + 6Step-by-step explanation:
Slope-intercept form:
y = mx + b, where m is slope and b is y-interceptWe see on the graph y-intercept is b = 6, point (0.6)
To find the slope we need a second point, choosing point (5, 1)
Using slope formula:
m = (1- 6)/(5 - 0) = -5/5 = -1So the line is:
y = -x + 6Answer:
y = -4/5x + 5
Step-by-step explanation:
the formula for slope intercept is y=mx+b.
m represents the slope of the line and b is the y intercept. all you have to do is replace those variables.
the y intercept is the point where the line crosses the y-axis (the line going up and down on the graph). (0,5) is the y intercept and so 5 would replace b in y=mx+b
so far we have y=mx+5
The slope is the vertical change between two points is called the rise, and the horizontal change is called the run. Starting from a point on the line you would move vertically until you're in line with another point. In this case, let's just use (0,5) from before. You would go up four to line up with a point. Then, move horizontally to meet up with the point and count the units, which is five here. And so, the slope would be 4/5.
And then you get the equation:
y=4/5x+b
Which equation represents the line that is parallel to y = 2 and passes through (-1,-6)?
Answer:
y=-6
Step-by-step explanation:
the line needs to be vertical to be parallel to y=2, and pass through (-1,-6)

Answer:
C
Step-by-step explanation:
conjugate just changes the sign of the radical (but nothing else)
what is the slope of this graph?
Answer: The slope is 0.
Step-by-step explanation: If the line is horizontal, the slope is 0
The rise is 0. 0 divided by any number is 0.
If the line is vertical, the slope is undefined.
No number can be divided by 0, so mathematicians call this situation "undefined."

The length of a rectangle is 5 inches more than three times the width.The perimeter is 64 inches. Find the length and width.
Answer:
L=25.25 in
W= 6.75in
Step-by-step explanation:
Step one
Given data
Let the width be x
W= x
and length
L= 3x+5
Perimeter= 64 in
Step two:
we want to find the dimension of the rectangle
We know that perimeter is
P= 2W+2L
64= 2*x+2*(3x+5)
64= 2x+6x+10
collect like terms
64-10=8x
54= 8x
divide both sides by 8
x= 54/8
x= 6.75in
We know that the length is
L= 3x+5
L= 3*6.75+5
L= 20.25+5
L=25.25 in
A high school club has 10 members who are seniors and 8 members who
are juniors. If a member is randomly selected to be the club president,

Answer:
The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
= [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]
Step-by-step explanation:
Explanation:-
Given A high school club has 10 members who are seniors and 8 members who are juniors
n(S) = 10 + 8 = 18
If a member is randomly selected to be the club president
Let 'E' be the event that the person will be a senior
The probability that the person will be a senior
[tex]P(E) = \frac{n(E)}{n(S)}[/tex]
[tex]P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}[/tex]
The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
= [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]
7% of what length is 200 feet
Answer:
Roughly 2857.14
Step-by-step explanation:
Answer:
2857.14285714 feet.
Step-by-step explanation:
If we put your question into an equation, we get:
7/100 * n = 200
We multiply both sides by 100 to get rid of the fraction, and get:
7n = 20000
Then, to find n, we divide both sides by 7.
Therefore,
n = 2857.14285714.

If cot 0= 4/3, find csc 0
Answer:
5/3
Step-by-step explanation:
Trigonometric ratio
Cot θ = Adjacent side/Opposite side
It is given that,
Cot θ = 4/3
Adjacent side = 4
Opposite side = 3
Csc θ = Hypotenuse/Opposite side
To find the Hypotenuse
Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²
Hypotenuse = √(3²+ 4²) = 5
To find Csc θ
Csc θ = Hypotenuse/Opposite side = 5/3

CAN U HELP I WILL GIVE 20 POINTS
Answer:
Your pay rate would be $7 per hour
Your friend's rate is $9 per hour
Step-by-step explanation:
To get the answer for your pay rate you'll have to divide 56/8 and then you'd get your number 7, so you get $7 dollars per hour.
To get the number for your friends pay rate you'd also do the same thing, divide. 36/4 gives you the number 9, so your friend gets $9 dollars per hour.

What is the measure of angle x in the figure
Answer:
167 degrees
Step-by-step explanation:
180-(180-((180-116)+103))
Answer: I think it might be y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)
x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)
Therefore, m/_x = 48 degrees.

Find the radius of a circle given that a central angle of measure pi/4 intercepts an arc of length 1.5in
Given:
Central angle = [tex]\dfrac{\pi}{4}[/tex]
Arc length = 1.5 in
To find:
The radius of the circle.
Solution:
We know that the formula for arc length is
[tex]s=r\theta[/tex]
Where r is radius and [tex]\theta [/tex] is the central angle in radian.
Substitute the given values in the above formula.
[tex]1.5=r\times \dfrac{\pi}{4}[/tex]
[tex]6=\pi r[/tex]
[tex]\dfrac{6}{\pi}=r[/tex]
[tex]\dfrac{6}{3.14}=r[/tex]
On further simplifiation, we get
[tex]r=1.910828[/tex]
[tex]r\approx 1.91[/tex]
Therefore, the radius of the circle is 1.91 in.
What is the depth of the soup ( the area shaded) 20cm is the diameter?
Answer:
8 cm
Step-by-step explanation:
Given that , the diameter of the semicircle is 20 cm . And the angle made by the level of liquid and the diameter is 37°. For diagram kindly refer to attachment .Let the depth of the liquid be represented by h . Now from the figure , ( attached ) :-
⇒ cos 37° = AB / AC
⇒ cos 37° = AB / 20 cm
⇒ 4/5 = AB / 20 cm .
⇒ AB = 4/5 * 20 cm .
⇒ AB = 16 cm .
Now , again AOB is s semicircle and AB is diameter , And the radius will be half of diameter .Hence here h = r = 16cm/2 = 8 cm .
Hence the depth of the soup is 8 cm .what is the solution 2x-y=-2 2x+4y=8
