Which does not describe slope? I will mark Brainly plz help fast
Answer:
Initial value
Step-by-step explanation:
Initial value never changes, whatsoever.
Slope is either a constant increase or decrease.
Unit rate, rate of change, and "per" all describe a rate at a certain point which is always fluctuating.
Answer:
Initial value
Step-by-step explanation:
The initial value is the y-intercept.
Clare has 80 pencils and 56 erasers to give away. What is the largest number of group that can formed with the same numbers of pencils and erasers in each group?
Answer:
56
Step-by-step explanation:
I assume each person in the group must have 1 pencil AND 1 eraser each.
Since you have more pencils than erasers, then the limiting factor is the number of erasers. So a group of 56 people will have 1 pencil And 1 eraser and Clare will have 24 pencils left over (assuming Clare has her own pencil and eraser - if not then the group size is 55 assuming Clare is not in the group)

Write an equation in slope-intercept form for the line between (2,7) and (6, 19)
Answer:
y= 3x +1
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate
Using the formula above, slope of line
[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]
Subst. m=3 into the equation:
y= 3x +c
To find the value of c, substitute a pair of coordinates.
When x= 2, y= 7,
7= 3(2) +c
7= 6 +c
c= 7 -6
c= 1
Thus, the equation of the line is y= 3x +1.
A person on top of a lookout tower spots a fire 100meter away. The height of the tower is 60 meters. Find the angle of elevation from the fire to the person.
Answer:
30.96° to the nearest hundredth
Step-by-step explanation:
Let x = angle of elevation
tan x = 60/100 = .6
x = arctan .6
x ≅ 30.96°

because 5 and 7 are the same angle that means the opposite of the 65 has to also be 65
Which is the equation of the line that passes through the points (-4, 8) and (1, 3)?
Answer:
Step-by-step explanation:
(3 - 8)/(1 + 4)= -5/5= -1
y - 8 = -(x + 4)
y - 8 = -x - 4
y = -x + 4

What is the length of arc S shown below? Enter an exact expression. The angle in the figure is a central angle in radians.
Answer:
The arc length S = 11.304 cm
Step-by-step explanation:
Explanation:-
Given that the radius of the circle 'r' = 6 cm
Given that the central angle = [tex]\frac{3\pi }{5}[/tex]
The Arc length is defined by
S = r θ
S = 6 × [tex]\frac{3\pi }{5}[/tex]
[tex]S = \frac{18\pi }{5}[/tex]
[tex]S = \frac{18(3.14) }{5}[/tex] (∵ π = 3.14)
S = 11.304 cm
The arc length S = 11.304 cm

Denise has 6 hours to spend for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 7mph and walks back at a speed of 3 mph, how long should she plan to spend walking back?
Answer:
She walks back for 4.2 hours
Step-by-step explanation:
Notice that we don't know the distance of the race (so let's name it "d").
She clearly would spend less time running (t1) the distance d at 7 mph, than when coming back walking (t2) at 3 mph.
But we know that the addition of both times must be 6 hours which is what she has to spend:
t1 + t2 = 6
Considering the equation that relates distance (D), time(t) , and speed (v) as:
v = D/t
we can solve for the times t1 and t2 in each trip (running vs walking){
t1 = d/7
t2 = d/3
then when we add these two equations term by term, we get:
t1 + t2 = d/7 + d/3
extract d common factor;
t1 + t2 = d (1/7 + 1/3)
replace t1 + t2 with the 6 hours:
6 = d (10/21)
multiply both sides by 21, and divide both sides by 10 to isolate d:
21 * 6 / 10 = d
d = 12.6 miles
Now knowing the distance she run and walked, we can find the time she spent walking back (t2)
t2 = 12.6 /3 = 4.2 hours

Using the angle addition postulate,
Parts of an Angle add up to form a new angle with the measure of that angle is the sum of the two separate angles.
Add ABD and DBC
[tex]65 + 60 = 125[/tex]
ABC=125
