The function f(x)= 3x + x2 + 2x rises as x grows very small. As x goes to negative
infinity, f(x) goes to infinity.
True
False
Answer:
.
Step-by-step explanation:
3x + x^2 + 2x
= x^2 + 5x
As x goes to negative infinity,
x^2 is always positive and will be higher than 5x as x increases so
f(x) goes to infinity
Brenda thought of a number divided it by 5 and then added seven to her answer she got the final number 11 what was her starting number
Answer:
20
Step-by-step explanation:
lets assume the number she thought of was x
[tex] \frac{x}{5} [/tex]
then she added 7 to it and got 11
[tex] \frac{x}{5} + 7 = 11[/tex]
l.c.m
[tex] \frac{x + 35}{5} = 11[/tex]
cross multiply
[tex]x + 35 = 11 \times 5[/tex]
[tex]x + 35 = 55 [/tex]
[tex]x = 55 - 35[/tex]
x = 20

You add a number to (–3) and the sum is negative. List four possible numbers you
might have added and four you could not have added.
Answer:
Four possible numbers
-4
-32
-2
-10
Four numbers that are not possible
100
120
20
10
Step-by-step explanation:
I choose the 4 possible numbers because if you add a negative to a negative, the answer will always be a negative. However if you added a positive like 100 to -3, the answer wouldn't be negative so that's why I chose those numbers.

What is the distance between W(3, 1) and X(-2,-5)? Round to the nearest tenth.
10
A. 61.0
B. 3.3
C. 2.2
D. 7.8
Answer:
D. 7.8
Step-by-step explanation:
Distance formula: [tex]\sqrt{(x_{2} - x_{1})^2 +( y_{2} - y_{1})^2 }[/tex]
Substituting (-2 - 3)² + (-5 - 1)²
Distance = [tex]\sqrt{(-5)^2 + (-6)^2}[/tex]
Distance = [tex]\sqrt{25 + 36}[/tex]
Distance = 7.8

Answer:3102+5780=8882
Step-by-step explanation:
Isabella and her brother, Santiago, want to make their grandma's famous fruit salad, but they can't remember how to make the honey-lime dressing. They decide to make two versions with different amounts of sweet honey and tangy lime, then compare them. Isabella mixes 4 tablespoons of honey and 2 tablespoons of lime juice. Santiago mixes 5 tablespoons of honey and 4 tablespoons of lime juice. Whose dressing is sweeter?
Answer:
Isabella
Step-by-step explanation:
4:2, is Isabella's ratio of honey:lime.
5:4, is Santiagio's ratio of honey:lime.
Therefore, Isabella has 6 equal parts over all and 4/6 of those parts are honey.
Santiago, has 9 equal parts, so he has 5/9 parts of honey.
Next is to make the denominators the same:
That would make the denominators 54 and then you just multiply the opposite denominator to the numerator:
5/9=36/54
4/6=30/54.
This means that Isabella's dressing is sweeter.
What is the slope of this line?
Step-by-step explanation:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Answer:
slope = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (3, 2) ← points on graph
m = [tex]\frac{2-5}{3-7}[/tex] = [tex]\frac{-3}{-4}[/tex] = [tex]\frac{3}{4}[/tex]

Solve the equation for the y–value and choose whether it is a direct variation or inverse variation
-4x + y = 0
Answer: Choice C
y = 4x
Direct variation
=====================================================
Explanation:
We add 4x to both sides to isolate y. That leads to y = 4x
This is a direct variation equation because it's in the form y = kx, for some constant k.

show that for all x >0
Answer:
See belowStep-by-step explanation:
We can show that for x = 0, both sides of the inequality get the value of 1.
With x > 0, the left side goes towards - ∞ with the negative slope and the right side is always positive.

Enrollment at a golf academy has grown exponentially since the academy opened. A graph depicting this growth is shown. Determine the percentage rate of growth.An exponential graph has Time in Years on the x-axis and Enrollments on the y axis. A curve that rises from left to right begins at zero comma fifteen and passes through four comma seventy-five.a. 1.5%b. 5%c. 50%d. 0.5%
Applying the points given, it is found that the growth rate of the exponential function is:
c. 50%
An exponential function has the following format:
[tex]y = a(1 + r)^x[/tex]
In which:
a is the initial value, that is, the value of y when x = 0.r is the growth rate, as a decimal.In this problem:
The curve begins at (0,15), thus a = 15.It passes through (4, 75), which means that when [tex]x = 4, y = 75[/tex], and this is used to find r.[tex]y = a(1 + r)^x[/tex]
[tex]75 = 15(1 + r)^4[/tex]
[tex](1 + r)^4 = 5[/tex]
[tex]\sqrt[4]{(1 + r)^4} = \sqrt[4]{5}[/tex]
[tex]1 + r = 1.4953[/tex]
[tex]r = 1.4953 - 1[/tex]
[tex]r = 0.4953[/tex]
Thus, approximately 50%, option c.

What is 500 miles decreased by 20%?
Answer:
400
Step-by-step explanation:
Percentage decrease = 20% × 500
New value = 500 - Percentage decrease
500 - (20% × 500) =
500 - 20% × 500 =
(1 - 20%) × 500 =
(100% - 20%) × 500 =
80% × 500 =
80 ÷ 100 × 500 =
80 × 500 ÷ 100 =
40,000 ÷ 100 =
