Each day, Yumiko exercises by first doing sit-ups and then running. Use her data and the trend line y = 9x + 5 to estimate Yumiko’s exercise time if she runs 5 mi.
Estimate: about ______ minutes
Answers
Answer:
50
Step-by-step explanation:
Given the trend line equation :
y = 9x + 5
Exercise time if she runs 5 miles :
From the trend line equation :
y = exercise time
x = miles ran
If she runs 5 miles ; then x = 5
y = 9(5) + 5
y = 45 + 5
y = 50

Q1) y=-6/2+4. - Q2) y=2/4x-1
Step-by-step explanation:
In the first question y intercept was +4 in the graph
after rise/run we will go down 6 and 2 to the right so it will be -6/2 so its y=-6/2+4
In the second question y intercept was -1 then we go down 2 steps and we go to the left 4 times so it will be -2/-4 =2/4 so the answer y=2/4x-1

Each table below shows the time and distance Samantha and her friends traveled on four different road trips. In which Table is there a linear relationship between time and distance?
Include explanation
Answers
Answer:
C
Step-by-step explanation:
C 160/2 = 80
240/3 = 80
400 / 5 = 80
480 / 6 = 80
C is linear
In table C, there is a linear relationship between time and distance
The correct answer is Table C
A linear relation is a relationship between distance (d) and time (t) when a distance changes over time at a constant rate.
From table A
At t = 2 hour, d = 120 miles
[tex]\frac{Distance}{Time} =\frac{120}{2}=60 miles/hour[/tex]
At t = 4 hour, d = 220 mile
[tex]\frac{Distance}{Time} =\frac{220}{4}=55 miles/hour[/tex]
The relationship between distance and time is not linear.
From table B
At t = 1 hour, d = 70 miles
[tex]\frac{Distance}{Time} =\frac{70}{1}=70 miles/hour[/tex]
At t = 2 hour, d = 150 miles
[tex]\frac{Distance}{Time} =\frac{150}{2}=75 miles/hour[/tex]
The relationship between distance and time is not linear.
From table C
At t = 2 hour, d = 160 miles
[tex]\frac{Distance}{Time} =\frac{160}{2}=80 miles/hour[/tex]
At t = 3 hour, d = 240 miles
[tex]\frac{Distance}{Time} =\frac{240}{3}=80 miles/hour[/tex]
At t = 5 hour, d = 400 miles
[tex]\frac{Distance}{Time} =\frac{400}{5}=80 miles/hour[/tex]
The relationship between distance and time is linear.
From table D
At t = 1 hour, d = 75 miles
[tex]\frac{Distance}{Time} =\frac{75}{1}=75 miles/hour[/tex]
At t = 2 hour, d = 150 miles
[tex]\frac{Distance}{Time} =\frac{150}{2}=75 miles/hour[/tex]
The relationship between distance and time is not linear.
Therefore, In Table C, there is a linear relationship between time and distance

it Given that f (x) = xsquared 2+3x+2 find f(0) the values of x for which f (x) =0
Answers
Step-by-step explanation:
f(x) = x^2 + 3x + 2
f(0) = (0)^2 + 3(0) + 2
= 2.
f(x) = 0
x^2 + 3x + 2 = 0
(x + 1)(x + 2) = 0
x + 1 = 0 x + 2 = 0
x = -1 x = -2
hence x = -1 or -2.
