: -- ) PLEASE HELP me out with this one
Answer:
A
Step-by-step explanation:
To answer this, we need to see what happens to the curves on the given interval
For f(x), we have that there is a decrease as we are moving from a higher positive value of y to a lower positive value of y over the specified interval
For g(x), we can see that we are moving from a lower positive y value to a higher positive y value
What this mean is that the first option is correct

You read 9.75 pages in your science book and 24.5pages of a play for English class. It takes you 1.2minutes to read each page of science and 0.8
of a minute to read each page of the play. How much time do you spend reading?
Answer:
the number of time spend in reading is 31.3 minutes
Step-by-step explanation:
The computation of the number of time spend in reading is as follows:
= 9.75 pages in science book × 1.2 minutes + 24.5 pages in english class × 0.8 minutes
= 11.7 minutes + 19.6 minutes
= 31.3 minutes
Hence, the number of time spend in reading is 31.3 minutes

20% of 150 is 30 :)
Step-by-step explanation:
Which equation represents a functional relationship?..
Y=6
X=6
Plz justify your answer~
Answer:
defines y as a function of x, because for every x value there is no more than a y value. (In fact for every x there is exactly one y value). We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
x=y2+6 does not define y as a function of x, because some value(s) of x have more than one y.
In general,
x=y2-6--->x+6=y2
So, all the values of x larger than -6 would have two y values.
For example, x=10 would be paired with y=4 and y=-4.
A function cannot assign more than one y to any x value.

Blanca jogged 8 days last month she jogged 1.25 miles on each day and burned 140 calories per mile while jogging how many calories did Blanca burn by jogging last month
Answer:
140p calories
Step-by-step explanation:
Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is
8 * 1.25 = 10 miles
Therefore, Bianca jogged a total of 10 miles the previous month.
Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.
If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.
Therefore, we conclude that Bianca burnt 1400 calories.
Matt's family traveled 7 10 of the distance to his uncle's house on Saturday. They traveled 2 3 of the remaining distance on Sunday. What fraction of the total distance to his uncle's house was traveled on Sunday?
Answer: 1 / 5 of the total distance
Step-by-step explanation:
On Saturday, Matt's family travelled 7/10 of the total distance to his uncle's house.
This means that the distance left is:
= 1 - 7/10 (Fractions should add up to one with one representing the total distance here)
= 3/10
The remaining distance is 3/10 and out of this distance they travelled 2/3 on Sunday.
The distance they traveled on Sunday was:
= Remaining distance * Proportion travelled
= 3/10 * 2/3
= 6/30
= 1 / 5 of the total distance
solve it (4+3x) (5)
Please explain how you got your answer!
Answer:
[tex](4 + 3x)(5) \\ = (5 \times 4) +( 5 \times3x) \\ = (20 + 15x) [/tex]
(20+15x) is the right answer.Answer:
(4 + 3x) (5)
(5 × 4) + (5 × 3x)
(20 + 15x)
Further we can find the value of x...
(20 + 15x)
15x = -20
x = -20/-15

.15m - .13m = 69.96 - 55.96
Answer:
m=7
Step-by-step explanation:
15m−13m=69.96−55.96
Step 1: Simplify both sides of the equation.
15m−13m=69.96−55.96
15m+−13m=69.96+−55.96
(15m+−13m)=(69.96+−55.96)(Combine Like Terms)
2m=14
2m=14
Step 2: Divide both sides by 2.

Solve: (8-u)-(5u+1) with steps
Answer:
-6u + 7
Step-by-Step Explanation:
Rearrange Terms:
(8 - u) - 1(5u + 1)
(-u + 8) - 1(5u + 1)
Distribute:
(-u + 8) - 1(5u + 1)
(-u + 8) - 5u - 1
Eliminate Redundant Parentheses:
(-u + 8) - 5u - 1
-u + 8 - 5u - 1
Subtract the Numbers:
-u + 8 - 5u - 1
-u + 7 - 5u
Combine Like Terms
-u + 7 - 5u
-6u + 7
Solution:
-6u + 7
13. If l is parallel to m, find the values of x and y.
Answer: 14. x = 16; y = 23
15. x = 9; y = 13
Step-by-step explanation:
14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)
4x + 4 = 7x - 44
Collect like terms
4x - 7x = -4 - 44
-3x = -48
Divide both sides by -3
x = -48/-3
x = 16
39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)
39 + 8y - 43 = 180
Add like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23
15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)
15x - 26 = 12x + 1
Collect like terms
15x - 12x = 26 + 1
3x = 27
Divide both sides by 3
x = 27/3
x = 9
28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)
Plug in the value of x
28 + 12(9) + 1 + 4y - 9 = 180
28 + 108 + 1 + 4y - 9 = 180
Add like terms
128 + 4y = 180
Subtract 128 from each side of the equation
4y = 180 - 128
4y = 52
Divide both sides by 4
y = 52/4
y = 13
Both answer and explantion.
