write the equation of the line in fully simplified slope intercept form
Answer:
[tex] y = \dfrac{5}{2}x - 4 [/tex]
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
where m = slope, and b = y-intercept.
From the graph, we see that the y-intercept, b, is -4, so now we have
y = mx - 4
Now we need to find the slope from the graph.
We see that the points (0, -4), the y-intercept, and (2, 1) are points of the line.
slope = rise/run
rise is a vertical distance. (Up is positive; down is negative.)
run is a horizontal distance. (Right is positive; left is negative.)
Start at (0, -4). Go up 5 units. That is a rise of +5 since you went up. Now go 2 units to the right. That is a run of +2 units since you went right. The rise is 5, and the run is 2.
m = slope = rise/run = 5/2
The equation is
[tex] y = \dfrac{5}{2}x - 4 [/tex]
find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.

Answer:
true
Step-by-step explanation:
What value of n will make this equation correct. 3/10 n = 4/5
Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds
1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.
Find the slope of the line that passes through the two points.
(-2,-8) and (4,4)
Answer:
The slope is 2
Step-by-step explanation:
Basically its Point slope form. Couldn't get their equation creator to work properly. Anyway....
(-2,-8) becomes the first set of x and y
(4,4) becomes the second set of x and y
For numerator.......4- -8=12
For denominator.......4- -2=6
12/6=2
The slope is 2

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.

Answer:
x=79
Step-by-step explanation:
22+2x=180
2x=180-22
2x=158
x=79
Answer:
79
Step-by-step explanation:
The two lines on the side of the triangles indicates that the opposite angles are equal to each other.
180-22=158
158/2=79 so f = 79

A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?
Answer:
Given that speed(v) = 20km/h and time(t) = 50 min
We have to find distance (d)
First convert speed into m/s
v = (20*1000m)/(1*3600s)
v = (50/9) m/s
Now convert time into second
t = 50*60 = 3000 sec
As we know that
d = v*t = (50/9)*3000 = 50000/3
d = 16666.67m or 16.67km
Ans: 16666.67m or 16.67km

5x - 8 = 3x + 4
Answer:
x=6
Step-by-step explanation:
5x - 8 = 3x + 4
+8 +8
5x=3x+12
-3x -3x
2x=+12
/2 /2
x=6
5x + 4 = -6
please step by step explanation
Answer:
x=-2
Step-by-step explanation:
5x+4=-6 so basically what you want to do is try to get x by itself
step 1 subtract 4 from each side
5x=-10
step 2 divide each side by 5
x=-2
Definition and description of gravity
Answer:
1. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
2. extreme or alarming importance; seriousness.
"crimes of the utmost gravity"
Step-by-step explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

find the measure of angle b. no fake answers.
Answer:
∠ b = 42°
Step-by-step explanation:
b and 48° form a right angle, then
b = 90° - 48° = 42°
Answer:
42 degrees
Step-by-step explanation:
The angle shared by 48 and b is 90 total degrees.
Subtract 48 from 90 to find the measure of b

Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : 2 is not a square !!
