Write an equation of the line that passes through the point (2,3) and is perpendicular to the line x+4y-8
Answer:
[tex]y = 4x - 5[/tex]
Step-by-step explanation:
rewrite the equation
[tex]x + 4y - 8 = 0 \\ 4y = - x + 8 \\ y = - \frac{1}{4} x + 2[/tex]
perpendicular slope is a negative reciprocal. we will use the negative reciprocal to find the y-intercept
[tex]3 = 4(2) + b \\ 3 = 8 + b \\ b = - 5[/tex]
The functions r and s are defined as follows.
r(x)= -2x-2
s(x)=2x² +2
Find the value of s (r (2)).
[tex]r(x) = -2x-2\\ s(x) = 2x^2+2[/tex]
[tex]s\big(r(2)\big) = s(-2\cdot 2-2) = s(-4-2) = s(-6) = 2\cdot(-6)^2+2 = 2\cdot 36+2 =\\ = 72+2 = 74[/tex]
[tex]\Rightarrow \boxed{s\big(r(2)\big) = 74}[/tex]
Answer:
74Step-by-step explanation:
Given functions:
r(x) = -2x - 2 s(x) = 2x² + 2Find s(r(2)) in steps:
r(2) = -2*2 - 2 = - 4 - 2 = - 6s(r(2)) = s(- 6) = 2(-6)² + 2 = 72 + 2 = 74which of the following expressions to 36x + 24y? choose all that apply.

Choose the number sentence that illustrates the distributive property of multiplication over addition.
A. 2 × (6 + 9) = (2 × 6) + 9
B. 2 × (6 + 9) = (2 × 6) + (2 × 9)
C. 2 × (6 + 9) = (2 + 6) × (2 + 9)
The answer is B It basically just expressing the 2×(6+9)
The expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.
What is distributive property?The distributive property is the property that expresses the distributive law of algebraic multiplication. Similarly, in polynomial expression we can use the distributive property, for example we can write a(c+b) in the form of (ac+bc).
We have an expression:
= 2 × (6 + 9)
After applying the distributive property:
= (2 × 6) + (2 × 9)
= (12) + (18)
= 30
Thus, the expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.

What is the domain of y=log 4(x+3)
Answer:
domain is the set of numbers you can use for x
Step-by-step explanation:
log_4(x+3)=y means
I mean it translates to
4^y=x+3
remember that x^m≥0 for all real values of x and m
it actually can equal 0 only when x=0 or when x is very small
so
therefor since 4^y>0, x+3>0 as well
solving we get
x>-3
all real numbers greater than -3

2(x-3)< 8 or x+5> 6
Solve the compound inequality
Answer:
1 < x < 7
Step-by-step explanation:
1. Solve for 2(x - 3)
Step 1: Simplify both sides of the equation.
[tex](2)(x)+(2)(-3)<8[/tex] [tex]2x - 6 < 8[/tex]Step 2: Add 6 to both sides.
[tex]2x - 6 + 6< 8 + 6[/tex] [tex]2x < 14[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} <\frac{14}{2}[/tex] [tex]x< 7[/tex]2. Solve for x + 5 > 6
Step 1: Subtract 5 from both sides.
[tex]x + 5 - 5 > 6 - 5[/tex] [tex]x > 1[/tex]3. Now that we know x is more than one but less than 7, we can write the solution as this: 1 < x < 7.
Therefore, the answer is 1 < x < 7.
Answer: 1. Solve for 2(x - 3) Step 1: Simplify both sides of the equation. Step 2: Add 6 to both sides. Step 3: Divide both sides by 2. 2. Solve for x + 5 > 6. Step 1: Subtract 5 from both sides.
