Answer:
The lines are perpendicular. Option B.
Explanation:
Equation of the Line
One of the characteristics of the line is its slope. It can be determined in two ways:
* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.
* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (3,4) and (7,3), thus the slope is:
[tex]\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}[/tex]
A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect
B. For two lines to be perpendicular, their slopes must meet the condition:
[tex]m1*m2=-1[/tex]
4*(-1/4)=-1
Both lines are perpendicular. Correct choice
D. Since choice B. is correct, this cannot be true. Incorrect

Answer:
38 degrees
Step-by-step explanation:
The two triangles are congruent, so do the following
1. Add 37 and 105 together
2. 37 + 105 = 142, subtract this from 180
3. This would amount to 38. So yeah.
Simplify Using Distributive Property
-6(2a + 8)
Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
[tex]\huge\boxed{\mathcal{HELLO!}}[/tex]
The distributive property states that
a(b+c)=ab+ac (we multiply a by everything inside the parentheses)
-6(2a+8)
-12a-48
[tex]\huge\boxed{Answer:-12a-48}[/tex]

Answer: x = 23
∠DBC = 23°
∠ABC = 157°
Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.
180 - 19 = 161
23 × 6 = 138
138 + 23 = 161
If x = 23°, then ∠DBC is 23°.
For ∠ABC, (6(x) + 19°
6(23) + 19°
6 × 23 = 138
138 + 19 = 157
∠ABC = 157°

9(m - 3) + 3m = 7m + 43
Answer:
m=14
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
M=14
Step-by-step explanation:
So distribute first
9m-27+3m=7m+43
Combine like Terms
12m-27=7m+43
Subtract 7m on both Sides
5m-27=43
Add 27 on both sides
5m=70
Iso,ate variable by dividing 5 on both sides
m=14

Answer:
[tex]g^{-1}[/tex] (x) = 8x + 48
Step-by-step explanation:
let y = g(x) and rearrange making x the subject, that is
y = [tex]\frac{x}{8}[/tex] - 6 ( add 6 to both sides )
y + 6 = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )
8(y + 6) = x , distribute
8y + 48 = x
Change y back into terms of x with x = [tex]g^{-1}[/tex] (x) , thus
[tex]g^{-1}[/tex] (x) = 8x + 48
