The equation of line passes through the points (4, 3) and (2, 7) will be;
⇒ y = - 2x + 11
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 3) and (2, 7)
Now,
Since, The equation of line passes through the points (4, 3) and (2, 7)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 3) / (2 - 4)
m = 4 / -2
m = - 2
Thus, The equation of line with slope - 2 is,
⇒ y - 3 = - 2 (x - 4)
⇒ y - 3 = - 2x + 8
⇒ y = - 2x + 11
Therefore, The equation of line passes through the points (4, 3) and
(2, 7) will be;
⇒ y = - 2x + 11

For the addition and subtraction of algebraic expressions,like terms are added or subtracted as per the signs given and unlike terms are kept as they are. The sum or difference of like terms give another like term in which it's coefficient is sum or difference of their coefficient.Remember the following facts of addition and subtraction :
Like terms can be added or subtracted. Only coefficients of like terms can be added or subtracted. In horizontal method , expressions are arranged in same row and put sign for addition or sign for subtraction and remove the bracket and then simplify.

x ÷ 4 + 5= 8 I need someone to do it and double check for me please.
= x/4 + 5 = 8
= x/4 = 8 - 5 ( transposing +5 from LHS to RHS changes +5 to -5 )
= x/4 = 3
= x = 3 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 l
= x = 12
Let us see whether the value of x is correct or not by placing 12 in the place of x .
= 12 ÷ 4 + 5 = 8
= 3 + 5 = 8
= 8 = 8
= LHS = RHS
Which means the value of x we found out is correct .
Therefore , x = 12 .Step-by-step explanation:
[tex] \frac{x}{4} + 5 = 8 \\ x + 5 = 32 \ \\ x = 32 - 5 \\ x27[/tex]

What is the probability of spinning a C?
Answer: 37.5%
Step-by-step explanation: Since there are 3 spaces for C it would be 3/8 for the amount of C's in all of the letters.
3/8 = 0.375 = 37.5%
Hope this helps!
The probability of spinning C will be 3/8 or 0375.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The spinner has eight equal section. And the 8 sections are marked as A, B, B, B, A, C, C, and C.
Then the total number of the event will be
Total event = 8 {A, B, B, B, A, C, C, C.}
Then the probability of spinning C will be
The favorable event will be
Favorable event = 3 {C, C, C}
P = 3 / 8
P = 0.375
The probability of spinning C will be 3/8 or 0375.

B. x= 12
C. x= 2
O D. x= 6
SUBMI
Answer:
Think
Step-by-step explanation:
4x - 6 + 2x = 18
You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.
So how do you do that? Combine the same calues together and seperate the rest
4x + 2x = 6x
6x = 18 + 6
6x = 24
x = 3
Practice practice practice. Simple stuff. You got this!
Answer:
A. x = 4
Step-by-step explanation:
To answer this question, we first have to combine like terms:
4x - 6 + 2x = 18
6x - 6 = 18
Now, we take away 6 from the left side and add it to the right side:
6x - 6 = 18
+6 +6
6x = 24
Then, we isolate the variable:
6x = 24
/6 /6
x = 4
