Answer:
The third graph
Step-by-step explanation:
The third graph is the only graph that could represent the equation because it is the only graph where the line goes through the y-intercept, -2. It is also positive, like the equation says the slope should be.

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, and mesurments of angle B=30 degrees.
Answer:
<D = 100
<E =30
<F =50
Step-by-step explanation
Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e
<A = <D
<B = <E
<C = <F
Given
<A = 100 then <D = 100
<B = 30°, then <E = 30°
To get <F, we will use the expression
<D+<E+<F = 180 (sum of angles in a triangle is 180°)
100+30+<F = 180
130+<F = 180
<F = 180-130
<F = 50°
Hence the measure of <F is 50°
f(1)=2
f(n+1) = f(n)+4
What is f(10)?
9514 1404 393
Answer:
38
Step-by-step explanation:
The recursion relation describes an arithmetic sequence with a first term of 2 and a common difference of 4. The explicit formula for the n-th term of the sequence is ...
f(n) = f(1) +d(n -1) . . . . . for first term f(1) and difference d
f(n) = 2 +4(n -1) = 4n -2
Then the 10th term is ...
f(10) = 4(10) -2
f(10) = 38
What is the slope of the line that passes through the points (4,5) and (12,7)?
Answer:
(2,8)
Step-by-step explanation:
If we plot both points on the graph and start at (4,5) we count up (rise) 2 and to the right (run) 8. This means they are both positive numbers as it goes up and to the right.
*Down or to the left would be negative.
Which point is located at 2/4 on the number line??
Answer:
on C
Step-by-step explanation:
The point K is located at 2/4.
What is fraction?"It is a number expressed as a quotient, in which a numerator is divided by a denominator."
For given example,
We have been given a fraction 2/4.
We simplify given fraction 2/4 as
2/4
= 1/2
=0.5
Also, the midpoint of 0 and 1 is,
(0 + 1)/2 = 0.5
In the given graph the midpoint of 0 and 1 is denoted by K
Therefore, the point K is located at 2/4.

Which equation shows the result of substituting and expression for y from the first equation into the second equation for the given system {y=x+5 {y-2x=2
Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
Answer:
(x + 5) – 2x = 2

Write a linear function f with f (5) = -1 and f(0) = -5.
f(x)=____
Answer:
We conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Step-by-step explanation:
Given
f(5) = -1f(0) = -5f(5) = -1 means at x = 5, y = -1
Hence, the point (5, -1) lies on the line function.
f(0) = -5 means at x = 0, y = -5
Hence, the point (0, -5) lies on the line function.
Thus, the two points on the linear line function graph are:
(5, -1)(0, -5)Finding the slope between the points (5, -1) and (0, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]
[tex]m=\frac{-5-\left(-1\right)}{0-5}[/tex]
[tex]m=\frac{4}{5}[/tex]
The slope-intercept form of the linear line function
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
We have already determined the slope which is: m = 4/5
We know the y-intercept can be determined by setting x = 0 and solving for y.
Thus, the point (0, -5) represents the y-intercept b = -5.
Now, substituting m = 4/5 and b = -5 in the slope-intercept form
[tex]y = mx+b[/tex]
y = 4/5x + (-5)
y = 4/5x - 5
Therefore, we conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5If each soda sells for $2.50, what is the expected daily total dollar amount taken in by the vendor from the sale of sodas?
Answer:
$34.38
Step-by-step explanation:
Y: A random variable that indicates the amount of money that the seller will receive.
p=2,50$
if x=0 → y=0.2,50=0$
if x=5 → y=5.2,50 = 12,5 $
if x=10 → y=10.2,50= 25$
if x=15 → y=15.2,50= 37,5$
if x=20 → y=20.2,50= 50 $
if x=25 → y=25.2,50= 62,5$
Y= { 0$ ; 12,5$ ; 25$ ; 37,5$ ; 50$ ; 62,5$ }
E(Y)= ∑Y.P(Y)
= 0.P(0)+12,5.P(12,5)+ 25.P(25)+ 37,5.P(37,5)+ 50.P(50)+ 62,5.P(62,5)
= 0.0,01+ 12,5.0,15+ 25.0,25+ 37,5.0,3+ 50.0,25+ 62,5.0,04
= 0 + 1,875 + 6,25 + 11,25 + 12,5 + 2,5
= 34,38$ expected value of the amount of money the seller receives.
