The second equation of this system is y = 3x −1 .
The solution of the system is (4,11).
Step-by-step explanation:
PLATO correct
The first equation of this system is y = 2x + 3 while the second equation of this system is y = 3x - 1.
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
For the first line, using the points (0, 3) and (2, 7):
[tex]y-3=\frac{7-3}{2-0}(x-0)\\ \\y=2x+3[/tex]
For the second line, using the points (0, -1) and (2, 5):
[tex]y-(-1)=\frac{11-(-1)}{4-0}(x-0)\\ \\y=3x-1[/tex]

find value of x question number F give step by step solution plz take photo or write step by step answer
Answer:
x= 17 cm
Step-by-step explanation:
Apply the Pythagorean relationship in this question which is stated mathematically as;
a² + b²= c²
where
a= is the base length, b is the height and c is the hypotenuse
First find length BC , where b= 8 cm and c=10cm and a=?
Hence;
a² + b²=c²
a² + 8²=10²
a²= 10²-8²
a²=100-64 =36
a=√36 = 6 cm
Now find AD=x where AB=8cm , BD = 6+9= 15cm
In this case, a=15 cm , b=8cm , c=?
a² + b²=c²
15² + 8² = c²
225 + 64 = c²
289= c²
√289 = c
17 cm = c = x

Sketch the graph y=− |x−1|+3 and answer the questions:
b)
What are the coordinates of its vertex?
c)
What are the coordinates of x- intercepts? (theres two)
Answer: The picture I showed is the sketch of the graph y=-|x-1|+3
b) The coordinates for the vertex is (1,3)
c) One of the coordinates for the x intercepts is (-2,0)
The other is (4,0)
Step-by-step explanation:
b)The vertex is the point I showed in the picture. It's where the graph moves in the opposite direction
c) The coordinates for the intercepts can be determined where the graph hits the x axis. At -2, the graph hits the x axis and at 4 the graph hits the x axis.
X intercepts always have a 0 for its y value of the coordinate. Therefore the coordinates are (-2,0) and (4,0)

What percent of the cats weight is between 0 and 5.9?
Answer:
there are 20 cats (male and female) in the catergory of 0.59 and there are 100 cats in total.
so you do 20/100 which is already out of 100 so it is 20%
Answer:
%20
Step-by-step explanation:
start by adding all the cats that are in the row labeled 0-5.9 to find the total number of cats that weigh between 0-5.9 lbs.
8 + 1 + 7 + 4 = 20
now add all the cats in the row labeled Total to find the total number of cats.
10 + 36 + 7 + 47 = 100
Since the total number of cats is 100 we should be able to find the percent very easily.
20/100 as a percent is %20
therefore the percent of cats that weigh between 0 and 5.9 lbs is %20

Given that for an arithmetic sequence, the first term is q and the second term is qz.
(a) Find the common difference d the general term Tn and the sum of the first n terms. Answer must
be in terms of q and z.
(b) Hence, find the sum of the first 10 terms in terms of q and z.
Answer:
[tex]d = q(z-1)[/tex]
[tex]S_n = \frac{nq}{2}(2 + (n-1)(z-1))[/tex]
[tex]S_{10} = 5q(9z -7)[/tex]
Step-by-step explanation:
Given
[tex]T_1 = q[/tex]
[tex]T_2 = qz[/tex]
Solving (a1): The common difference (d)
d is calculated as
[tex]d = T_2 - T_1[/tex]
This gives:
[tex]d = qz - q[/tex]
Factorize:
[tex]d = q(z-1)[/tex]
Solving (a2): Sum of n terms
This is calculated using:
[tex]S_n = \frac{n}{2}(2*T_1 + (n-1)d)[/tex]
Substitute values for T1 and d
[tex]S_n = \frac{n}{2}(2*q + (n-1)q(z-1))[/tex]
[tex]S_n = \frac{n}{2}(2q + q(n-1)(z-1))[/tex]
Factorize:
[tex]S_n = \frac{n}{2}(q(2 + (n-1)(z-1)))[/tex]
[tex]S_n = \frac{nq}{2}(2 + (n-1)(z-1))[/tex]
Solving (b): Sum of first 10.
In this case, n = 10
So:
[tex]S_n = \frac{nq}{2}(2 + (n-1)(z-1))[/tex]
becomes
[tex]S_{10} = \frac{10 * q}{2}(2 + (10-1)(z-1))[/tex]
[tex]S_{10} = 5 * q(2 + 9(z-1))[/tex]
[tex]S_{10} = 5q(2 + 9(z-1))[/tex]
[tex]S_{10} = 5q(2 + 9z-9)[/tex]
[tex]S_{10} = 5q(2 -9+ 9z)[/tex]
[tex]S_{10} = 5q(-7+ 9z)[/tex]
[tex]S_{10} = 5q(9z -7)[/tex]
Given that the first term and the second term of an arithmetic sequence is q and qz respectively, therefore:
a. Common difference (d) = [tex]\mathbf{d = q(z - 1)}[/tex]
Sum of the first n terms is: [tex]\mathbf{S_n = \frac{qn}{2}[2 + (n - 1)(z - 1)]}[/tex]
b. [tex]\mathbf{S_{10} = 5q(9z - 7)}[/tex]
Recall:
The common difference (d) of an arithmetic sequence = difference between the next term and the previous termSum of n terms, [tex]S_n[/tex] of arithmetic sequence = [tex]\frac{n}{2}[2a + (n - 1)d][/tex]Given:
First term, [tex]T_1 = q[/tex] (this is also "a")Second term, [tex]\\\\T_2 = qz[/tex]a. Common difference (d) = [tex]T_2 - T_1[/tex]
Substitute[tex]d = qz - q\\\\\mathbf{d = q(z - 1)}[/tex]
Sum of n terms:
[tex]T_n = \frac{n}{2}[2a + (n - 1)d][/tex]
Substitute by plugging in the value of d and a[tex]S_n = \frac{n}{2}[2(q) + (n - 1)q(z - 1)]\\\\S_n = \frac{n}{2}[2q + q(n - 1)(z - 1)]\\\\S_n = \frac{qn}{2}[2 + 1(n - 1)(z - 1)]\\\\\mathbf{S_n = \frac{qn}{2}[2 + (n - 1)(z - 1)]}[/tex]
b. Sum of the first 10 terms:
Substitute n = 10 into [tex]S_n = \frac{qn}{2}[2 + (n - 1)(z - 1)][/tex][tex]S_{10} = \frac{q(10)}{2}[2 + (10 - 1)(z - 1)][/tex]
Simplify[tex]S_{10} = 5q[2 + (9)(z - 1)]\\\\S_{10} = 5q(2 + 9z - 9)\\\\[/tex]
Add like terms[tex]\mathbf{S_{10} = 5q(9z - 7)}[/tex]
In summary, given that the first term and the second term of an arithmetic sequence is q and qz respectively, therefore:
a. Common difference (d) = [tex]\mathbf{d = q(z - 1)}[/tex]
Sum of the first n terms is: [tex]\mathbf{S_n = \frac{qn}{2}[2 + (n - 1)(z - 1)]}[/tex]
b. [tex]\mathbf{S_{10} = 5q(9z - 7)}[/tex]
