Step-by-step explanation:
Step 1: Define
-3x + 40 = -23
Step 2: Solve for x
Isolate x term: -3x = -63Isolate x: x = 21Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -3(21) + 40 = -23Multiply: -63 + 40 = -23Add: -23 = -23Here we see that -23 does indeed equal -23.
∴ x = 21 is the solution to the equation.

A line with a slope of -7 passes through the points (-8, 7) and (-7, k). What is the value of
K?
Answer:
k = 0
Step-by-step explanation:
On the graph, the second point would be at (-7,0)
Answer:
k = 0
Step-by-step explanation:
We can find the answer to this question by using the slope equation:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's define some variables:
[tex]\frac{k - 7}{-7-(-8)} = \frac{k-7}{1} = k- 7[/tex]
We know the slope is -7 so we can put k-7 equal to it and solve
[tex]k-7 = -7\\k = 0[/tex]
We find that k is equal to 0.
I hope this helps!!

What Solution set of the equation 9x^2 +6x = -1
Answer:
[tex] x=\{- \frac{1}{3}\}[/tex]
Step-by-step explanation:
[tex]9x^2 +6x = -1 \\ \\ 9x^2 +6x + 1 = 0\\ \\ {(3x + 1)}^{2} = 0 \\ \\ 3x + 1 = 0 \\ \\ 3x = - 1 \\ \\ x = - \frac{1}{3}\\\\x=\{- \frac{1}{3}\} [/tex]

What is the value of x?

2.
39
3
45
4
126
Answer:
option 3, 45
Step-by-step explanation:
3x - 9° + 30° + 24° = 180° (angle sum property of a triangle)
3x - 9° + 54° = 180°
3x + 45° = 180°
3x = 180° - 45°
3x = 135°
x = 135/3
x = 45°
therefore, option 3 is the correct option

1- (2x+4)= 4x+5 . What is the correct solution ??
Answer:
x=4
Step-by-step explanation:
We move all terms to the left:
1-(2x+4)-(-4x+5)=0
We get rid of parentheses
-2x+4x-4-5+1=0
We add all the numbers together, and all the variables
2x-8=0
We move all terms containing x to the left, all other terms to the right
2x=8
x=8/2
x=4

which expression is equivalent to 4x^2 sqrt 5x^4 • 3 sqrt 5x^8 if x ≠ 0
Answer:
B
Step-by-step explanation:
The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.
Given:
The given expression is:
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]
To find:
The equivalent expression.
Explanation:
We have,
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]
On simplification, we get
[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]
[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]
[tex]=12(x^{8})(5)[/tex]
[tex]=16x^{8}[/tex]
Therefore, the correct option is B.

Paula is the student council member responsible for planning an outdoor student dinner dance. Plans include
hiring a band and buying and serving dinner. She wants to keep the ticket price as low as possible to encourage
student attendance while still covering the cost of the band and the food.
1.) Band A charges $700 to play for the evening and Band B charges $550 plus $1.50 per student.
a. Write a system of equations to represent the costs of the two bands. Use y for total cost and use x for
number of students.
Answer:
Band A:y=700
Band B:y=550+1.50x
Step-by-step explanation:
Band A: since they are a fixed rate no matter how many students the equation would be y=700 . There is no need for x since there is no extra price for students
Band B: Since this band charges 550 plus 1.50 per student we will need a x in our equation
y=550+1.50x
The difference between the two equations is that in Band B we need to add the price per student.
