Which statement is true?
OA Jake made a mistake in step 2.
OB. Jake made a mistake in step 4.
OC. Jake made a mistake in step 5.
OD. Jake solved the equation correctly.
Two equal expressions combine to make an equation. Jake made a mistake in step 2 and the value of x is 24. The right answer is A.
When two equal expressions are added together with the aid of the equal sign "=," an equation is created.
You may find the solution to the given equation 1/3x + 7 = 15 as shown below.
1/3x + 7 = 15
Subtract 7 from both sides of the given equation
=> 1/3x + 7 - 7
=15 - 7.
1/3x = 8
Multiply both sides of the given equation by 3,
3 x 1/3x = 3 X 8.
x = 24
Hence, X has a value of 24. Jake also erred on the second step.

Triangle IHJ is similar to triangle RST.
What is the length of side RT?
Answer:
Length of RT = 6 mm
Step-by-step explanation:
When the triangles are similar the ratio of corresponding sides are equal.
In given triangles we have ( we can take ratio of two sides also)
[tex]\frac{JI}{RT}=\frac{HI}{SR}[/tex]
We need to find length of RT = x
While length of JI= 8 mm
Length of HI = 12 mm
Length of SR = 9 mm
Putting values in formula and finding length of RT
[tex]\frac{8}{x}=\frac{12}{9} \\Cross\:Multiply\\9\times 8= 12\times 8\\72=12x\\x=\frac{72}{12}\\x=6\:mm[/tex]
So, Length of RT = x = 6 mm

Answer:
✔️The correct system of linear equations:
2x + 3y = 34
3x + 2y = 36
Cost of each roast beef sandwich: $8
Cost of each turkey sandwich: $6
Step-by-step explanation:
Cost of each roast beef sandwich = x
Cost of each turkey sandwich = y
First platter consists of:
2 roast beef sandwiches, which costs 2 × x = 2x, and,
3 turkey sandwiches, which costs 3 × y = 3y.
Total cost of first platter is $34.
Thus, an equation that represents this scenario would be:
2x + 3y = 34.
The other platter consists of:
3 roast beef sandwiches, which costs 3 × x = 3x, and,
2 turkey sandwiches, which costs 2 × y = 2y.
Total cost is $36.
Thus, an equation that represents this scenario would be:
3x + 2y = 36.
The correct system of linear equations would be:
2x + 3y = 34
3x + 2y = 36
Find the value of x and y by solving simultaneously.
Thus:
2x + 3y = 34 ----› Eqn. 1 × 2
3x + 2y = 36 ----› Eqn. 2 × 3
4x + 6y = 68
9x + 6y = 108
Subtract
-5x = - 40
Divide both sides by -5
x = 8
Cost of each roast beef sandwich = x = $8
Substitute x = 8 into eqn. 1.
2x + 3y = 34 ----› Eqn.
2(8) + 3y = 34
16 + 3y = 34
3y = 34 - 16
3y = 18
Divide both sides by 3
y = 6
Cost of each turkey sandwich = y = $6

=====================================================
Explanation:
When two letters are placed together without any space between them, this implies multiplication.
gf = g times f
So we'll be multiplying the functions g and f.
There are two ways to approach this problem.
----------------------------------------------
Method 1
First we need to find f(4) and g(4)
f(x) = 2x+3
f(4) = 2*4+3
f(4) = 8+3
f(4) = 11
g(x) = 2x^2-1
g(4) = 2(4)^2-1
g(4) = 2(16)-1
g(4) = 32-1
g(4) = 31
Now we multiply the results
gf(4) = g(4)*f(4)
gf(4) = 11*31
gf(4) = 341
----------------------------------------------
Method 2
We'll multiply g(x) with f(x) like so
gf(x) = g(x)*f(x)
gf(x) = (2x^2-1)*(2x+3)
gf(x) = 2x^2*(2x+3) - 1(2x+3) .... distribute
gf(x) = 4x^3+6x^2-2x-3 .... distribute again
Now plug in x = 4
gf(x) = 4x^3+6x^2-2x-3
gf(4) = 4(4)^3+6(4)^2-2(4)-3
gf(4) = 4(64)+6(16)-2(4)-3
gf(4) = 256+96-8-3
gf(4) = 341
We get the same result. Method 1 may be the better method, but it will depend on your preference.

Answer: A is the answer
Step-by-step explanation:
A function is shown below :
what is f(3)?
Please explain if possible!! Thank you!!
Given:
[tex]f(x)=\begin{cases}-\dfrac{1}{2}x^2 & 0<x\leq 3 \\ x^3+2x & x>3\end{cases}[/tex]
To find:
The value of f(3).
Step-by-step explanation:
For x=3, we have
[tex]f(x)=-\dfrac{1}{2}x^2[/tex]
Putting x=3 in the above function, we get
[tex]f(3)=-\dfrac{1}{2}(3)^2[/tex]
[tex]f(3)=-\dfrac{1}{2}(9)[/tex]
[tex]f(3)=-\dfrac{9}{2}[/tex]
Therefore, the value of f(3) is [tex]-\dfrac{9}{2}[/tex]. So, the correct option is a.

now for the slope
find two points on the line, i chose(8 , 120) and (4 , 240)
use the slope formula: y2-y1 over x2-x1
240-120=120 and 4-8= -4
so the slope is 120/-4 and that can be simplified to 30/-1 or -30

There are 234 pieces of candy in 9 bags of candy. If there are the same amount of pieces of candy in each bag, how many total pieces of candy are in 5 bags?
Answer:
130 pieces of candy in 5 bags
Step-by-step explanation:
234/9 equals 26, that means there would be 26 pieces of candy in 9 bags, therefore 26x5 equals 130, and just to make sure, divide 130/26 to check if its wrong, but it should be 130. :) hope this helps you out!
On a coordinate plane, 2 lines intersect at (negative 2, negative 5). What point appears to be the solution to the system of equations shown in the graph? ( , )
Answer:
We conclude that the point of intersection i.e (x, y) = (-2, -5) will appear to be the solution to the system of equations.
Step-by-step explanation:
We know that when two lines meet or intersect at a point in the coordinate plane, the point where they meet is called the point of intersection.
The point of intersection is termed as the solution of the system of equations on a coordinate plane.
Given that the two lines intersect at (-2, -5)
In other words,
at x = -2, y = -5Thus, the point of intersection = (x, y) = (-2, -5)
Thus, we conclude that the point of intersection i.e (x, y) = (-2, -5) will appear to be the solution to the system of equations.
