Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of the given equation.
Equation: y-intercept of 1, 3x – y = 5
Answer:
The equation is [tex]y=-\frac{1}{3}x+1[/tex]
Step-by-step explanation:
You have the y-int, so you just need to find the slope, which is the negative reciprocal of A/B since it is perpendicular. Plugging in the numbers gets you the above equation.
what is 96-4.5y-3.2y=5.6y+42.80
PLEASE HELP!!!!

Solve for x.
y=(2 + x)m
Answer:
x = [tex]\frac{y-2m}{m}[/tex]
Step-by-step explanation:
Given
y = (2 + x)m ← distribute parenthesis by m
y = 2m + mx ( subtract 2m from both sides )
y - 2m = mx ( divide both sides by m )
[tex]\frac{y-2m}{m}[/tex] = x
The seventh term of an arithmetic progression is equal to twice the fifth term. The sum
of the first seven terms is 84. Find the first term.
Answer:
a₁ = - 24
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₇ = 2a₅ , then
a₁ + 6d = 2(a₁ + 4d) = 2a₁ + 8d ( subtract 2a₁ + 8d from both sides )
- a₁ - 2d = 0 → (1)
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
Given [tex]S_{7}[/tex] = 84 , then
[tex]\frac{7}{2}[/tex] (2a₁ + 6d) = 84
3.5(2a₁ + 6d) = 84 ( divide both sides by 3.5 )
2a₁ + 6d = 24 → (2)
Thus we have 2 equations
- a₁ - 2d = 0 → (1)
2a₁ + 6d = 24 → (2)
Multiplying (1) by 3 and adding to (2) will eliminate d
- 3a₁ - 6d = 0 → (3)
Add (2) and (3) term by term to eliminate d
- a₁ = 24 ( multiply both sides by - 1 )
a₁ = - 24

Answer:
22.222222%
Step-by-step explanation:
all together the entire video is 9 min and 2 of those are the intro so 2/9 and that as a percent is the answer
Answer: 22.23% (Infinitely Long)
Step-by-step explanation:
9 = 100%
9 (100%) - 7 (77.78%) [Also Infinitely Long] = 2 (22.23%) [Infinitely Long]

find the distance between points (2, 9) and (5, 4) to the nearest tenth
Answer:
[tex]Distance = 5.8[/tex]
Step-by-step explanation:
[tex]d=\sqrt{(4-9)^{2} } { (5-2)} ^{2} \\[/tex]
[tex]d = -5^{2} + 3^{2}[/tex]
[tex]d= 25 + 9[/tex]
[tex]d= \sqrt{34}[/tex]
[tex]distance = 5.8[/tex]
Felix used place value and the distributive property to rewrite the expression 9(278). His work is shown below. 9(278) = 9(200 + 70 + 8) What should Felix do to find the product? Select all that apply. Multiply 9(200) and multiply 70(8). Multiply 9(200), 9(70), and 9(8). Multiply 9(200) and then add (70 + 8). Distribute the 9 to each addend. Find the sum of (1,800 + 630 + 72).
Step-by-step explanation:
Distributive property is as follows :
a(b+c) = ab + ac
Felix used place value and the distributive property to rewrite the expression 9(278).
Place value of 278 = 200 + 70 +8
He has done like : 9(278) = 9(200 + 70 + 8). Now, the steps are as follows :
9(278) = 9(200 + 70 + 8)
= 9(200)+9(70)+9(8)
= 1800 + 630 +72
= 2502
Hence, option (d) "Distribute the 9 to each addend. Find the sum of (1,800 + 630 + 72)" should be the correct answer.
