Over what interval of x values is the function increasing ?
A) -infinity,2
B) (-1,5)
C)- infinity, 9
D) 2, infinity
Answer:
C. (-infinity,9)
Step-by-step explanation:
The correct interval of x values is the function increasing is,
⇒ (- ∞, 9)
Since, We know that,
If f(x) is increasing on (a, b),
Then, f(a) < f(b) on (a, b).
Here, By the graph of function, we get;
The correct interval of x values is the function increasing is,
⇒ (- ∞, 9)
Thus, The correct option is,
⇒ (- ∞, 9)

what is the gradient of the line y=3x+7
Answer:
gradient = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = 3x + 7 ← is in slope- intercept form
with gradient m = 3
The gradient of the line can be obtained from the given equation as 3.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The given equation of the line is y = 3x + 7.
Compare this equation with y = mx + c to get,
m = 3 and c = 7.
Where m and c are the slope and y-intercept of the line respectively.
Since, the gradient and slope are similar.
The gradient of the equation is 3.
Hence, the gradient of the line is 3.

A package of construction paper has 6 sheets of red paper, 14 sheets of blue pape
and 10 sheets of yellow paper. If Dexter bought enough packages of construction
paper to have 50 sheets of yellow paper, how many sheets of red paper does he
have?
Answer:
50/10=5 so the ratio is 5 times more
there was 6 sheets of red paper and there is 5 times more so 5 x 6 = 30 red sheets
30 red sheets
Hope this helps
Step-by-step explanation:
Answer:
30 sheets of red paper

if you were to solve the following system by substitution, what would be the best variable to solve for and from what equation? 2x+8y=12 3x-8y=11
Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11

c) Uranus has three moons less than Saturn. Together, they have thirty-three moons. How many
moons does each planet have?
Answer:
Uranus : 15
Saturn : 18
Step-by-step explanation:
Uranus = U
Saturn = S
1) U= S - 3
2) U+ S = 33
1)* U - S = -3
2)* U + S = 33
1)* + 2)* 2U = 30, so U = 15
Then Saturn will have 18 (because they add up to 33)
On a road trip you see a sign "350 km to Indianapolis". About how many hours will it
take you to drive to Indianapolis if you are traveling at 68 mi/h (1 mile 1.61 km).
Round your answer to the nearest hundredth.
Answer: 3.20 hours
Step-by-step explanation:
Hi, to answer this question, first we have to convert the kilometers into miles:
Since: 1 mile = 1.61 km
For 350km:
350 /1.61 = 217.39 miles
Next, we have to apply the next formula:
Time = distance / speed rateReplacing with the values given:
Time = 217.39 mi / 68 mi/h = 3.20 hours

What is the value of x in this figure?
A.) 103√3
B.) 5√3
C.) 5
D.) 5√2
I think its 5 or 5√3, but don't know
Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
*Since the options you have are in exact values, you can't use a calculator just to find x.
Cos 30 in exact values is √3/2
*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees
So to find x:
x = √3/2 x 10
x = 5√3

Answer: 5, 8
Step-by-step explanation:
The difference between 3 times a number and -8 is BETWEEN 23 and 32
Note: "difference" means subtraction --> 3x - (-8) --> 3x + 8
23 < 3x + 8 < 32
15 < 3x < 24 subtracted 8 from all 3 sides
--> 5 < x < 8 divided 3 from all 3 sides

At a TV.repair shop, the amount charged for labor depends on the time the
repair technician works. Which of the following shows this idea expressed in
function notation?
A. Amount(hours worked)
B. Time(number of televisions)
C. Amount(number of televisions)
D. Time(amount charged)
SEBNI
Answer:
A. Amount(hours worked)
Step-by-step explanation:
Function notation is a way of converting a written description of a function to a concise form that is easy to read.
It is another way of representing the y-value in a function, y = ƒ(something)
Let's convert the word expression to function notation:
"The amount charged for labour depends on the time the repair technician works." "The amount depends on the hours worked." "The amount is a function of the hours worked." Amount = amount(hours worked) y = a(h)

A bicycle wheel turns at 80 rpm. If the rider travels 27.227 m in 10 seconds, what is the radius of the wheels of the bicycle?
Answer:
2.042 meters
Step-by-step explanation:
We have that the angular speed is 80 rpm and we can calculate the linear speed, we know that the linear speed is equal to the radius times the angular speed, like this:
v = w * r
w = 80 rpm, but we must pass it to seconds, that is:
80/60 = 1,333 rps, that is, revolutions per second, to have the same time unit as the linear speed.
v = distance / time = 27,227 / 10 = 2.7227
therefore, the radius would be:
r = v / w = 2.7227 / 1,333
r = 2.042
Which means that the radius is 2.042 meters.
