Answer: To use the Vertical Line Test, you draw a line parallel to the y-axis for any value of x and if the line intersects the curve graphed, then the curve is not a function. We use Vertical Line Tests to see if curves are functions.

Aluminium has a density of 2900 kg/mº. A construction company
need four cubic metres of aluminium.
Calculate the mass of the aluminium needed.
Answer:
11600kg
Step-by-step explanation:
Given parameters:
Density of aluminium = 2900kg/m³
Volume needed = 4m³
Unknown:
Mass of the aluminum needed = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Mass = density x volume
Now, insert the parameters and solve;
Mass = 2900 x 4 = 11600kg

How many solutions does the equation 1/5(20x-25)=4x-5 have?
Answer:
Infinitely many solutions
Step-by-step explanation:
we need to simplify the equations
1/5(20x-25)=4x-5
distribute the 1/5
4x-5=4x-5
+5 to each side
4x=4x
divide each side by 4
x=x
since x=x there are infinitely many solutions.
Answer:
no real solutions
Step-by-step explanation:
1/5(20x-25)=4x-5
1/5(20-25)=4-5
1/5(-5)=1
-1=1
Find y-intercept for 9x-5y=0.
Answer:
y=-9/5x+0 the y intercept would simply be 0
Step-by-step explanation:
Answer:
y=0
Step-by-step explanation:
9x-5y=0
9(0)-5y=0
-5y=0
-5y/-5=0/-5
y=0 (y intercept)
9x-5y=0
9x-5(0)= 0
9x=0
9x/9=0/9
x=0 (x intercept)
Hope this Helps :)
Have a good day :)
Solve the inequality 5x-6<=2+(3x-4)
Answer:
x =< 2
Step-by-step explanation:
5x - 6 =< 2 + (3x - 4)
5x - 6 =< 2 + 3x - 4
5x - 3x =< 2 - 4 + 6
2x =< 4
x =< 2

Answer:
g(x) = x² + 4x + 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (- 2, 1 ), thus
y = a(x + 2)² + 1
To find a substitute (0, 5) ← y- intercept into the equation
5 = a (0 + 2)² + 1 ( subtract 1 from both sides )
4 = 4a ( divide both sides by 4 )
a = 1
g(x) = (x + 2)² + 1 ← in vertex form
Expand parenthesis and simplify
g(x) = x² + 4x + 4 + 1, then
g(x) = x² + 4x + 5 ← in standard form
To celebrate the first day of school, Reagan brought in a tray of caramel brownies and walnut brownies. The tray had a total of 20 brownies, of which 10% were caramel. How many caramel brownies did Reagan bring?
Answer:
18 I think
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Reagan brought 2 caramel brownies.
Solve using a proportion.
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
You're trying to find how many brownies he brought were caramel. We know Reagan brought a total of 20 brownies. Therefore since you don't know how many caramel brownies he brought, the fraction would be ?/20. Next, you know he brought brownies in which 10% were caramel. In proportions, the denominator would be 100% since that is the total percentage. Therefore, the proportion would be 10%/100%. Now we just have to cross multiply.
Proportion:
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
10 x 20 = 200
200/100= 2
Thus, Reagan brought 2 caramel brownies.

The Population in Corpus Christi in 1970 was 204,525. The population in 2002 was 276,877. Create an
exponential equation and find out what the population will be in 2017?
When solving for b round it to the 4 decimals to use in the Equation. WHAT WILL BE THE POPULATION IN
2017?
Answer:
The population is 2017 is 291,254
Step-by-step explanation:
The exponential equation will be in the form
P = I( 1 + r)^t
where P is the present population
I is the population initially at 1970
r is the annual growth percentage
t is the number of years since 1970
So for 2002, we have
r in this case will be 2002-1970 = 32
277,877 = 204,525(1 + r)^32
(1 + r)^32 = 1.3586
1 + r = 1.0096
r = 1.0096-1
r = 0.0096
So the growth percentage is 0.96% annually
So the population in 2017 where t will be 2017-1970 = 37 will be
P = 204,525(1 + 0.0096)^37
P = 204,525(1.0096)^37
P = 291,254
Which equation in standard form has a graph that passes through the point (5, −2) and has a slope of 72 ?
A. 7x − 2y = 35
A. 7x − 2y = 35
B. 7x − 2y = 39
B. 7x − 2y = 39
C. 7x − 2y = −31
C. 7x − 2y = −31
D. 7x − 2y = −24
D. 7x − 2y = −24
Given:
Consider the graph passes through the point (5, −2) and has a slope of [tex]\dfrac{7}{2}[/tex].
To find:
The equation of graph in standard form.
Solution:
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope and [tex](x_1,y_1)[/tex] is the point lies on the line.
Slope is [tex]\dfrac{7}{2}[/tex] and graph passes through (5,-2), so the equation of line is
[tex]y-(-2)=\dfrac{7}{2}(x-5)[/tex]
[tex]y+2=\dfrac{7}{2}(x-5)[/tex]
Multiply both sides by 2.
[tex]2(y+2)=7(x-5)[/tex]
[tex]2y+4=7x-35[/tex]
[tex]4+35=7x-2y[/tex]
[tex]39=7x-2y[/tex]
The required equation is [tex]7x-2y=39[/tex].
Therefore, the correct option is B.

The slope of a line is 1, and the y-intercept is -1. What is the equation of the line written in slope-intercept form?
Answer:
y = x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b
m is the slope and b is the y-intercept so it would be:
y = x -1 but u don't have to write 1x just x will do
Answer:
y = x - 1Step-by-step explanation:
slope intercept form
y = mx + bwhere m = 1
y-intercept = b = -1
therefore:
y = x - 1PLEASE HELP ASAP:(....

One year, the population of a city was 130,000. Several years later it was 135,200.
Find the percent increase.
Answer:
Increase in percent = 4%
Step-by-step explanation:
Given:
Present population = 130,000
Future population = 135,200
Find:
Increase in percent
Computation:
Increase in population = Future population - Present population
Increase in population = 135,200 - 130,000
Increase in population = 5,200
Increase in percent = [Increase in population / Present population]100
Increase in percent = [5,200/130,000] 100
Increase in percent = 4%

Evaluate g(x)=6x when x=-3,0, and 4 .
Answer:
-3 = -18
0 = 0
4 = 24
Step-by-step explanation:
-3... so 6(-3) equals -18 because a positive times a negative equals a negative
0... so 6 (0) equals 0 because anything multiplied by 0 equals 0
4... so 6 (4) equals 24
() means multiplied by so if it’s y(x) then that means y is multiplied by x :)

Calc how much interest you would earn on a deposit of $8500 at 2.75%,
compounded annually, for a term of 4 years?
9514 1404 393
Answer:
$974.28
Step-by-step explanation:
The formula for the account balance is ...
A = P(1 +r)^t
Subtracting the principal gives the amount of interest.
I = P((1 +r)^t -1)
i = $8500(1.0275^4 -1) ≈ $974.28
You would earn $974.28 in interest over that time period.
