Find the equation of the line that passes through (3,-4) and is parallel to 3x+y+2=0
Leave your answer in the form y=mx+c
Answers
Answer:
y=-3x+5
Step-by-step explanation:
it parallel to 3x+y+2=0 => line is: 3x+y+c=0
It through (3;-4) => 3(3)+(-4)+c=0 <=> c=-5
Line is 3x+y-5=0 => y=-3x+5
Answer:
Since it’s parallel to 3x+y+2=0 then it must be of the form 3x+y+k=0. Since (3,-4) is on the line we have 0=3*3-4+k=k+5, therefore k=-5 and the equation is 3x+y-5=0
In the form y=mx+c this becomes y=-3x+5

What is the solution to the system of equations?
y = 2x -1
y = -x +5
Answers
x= −2 and y=3
I can't explain this very well, sorry.
x= 4/3
y= 11/3.
Step by step: (substitution)
2x+1=-x+5
Add x to both sides.
3x+1=5.
Subtract 1.
3x=4.
Divide by 3.
x=4/3.
Use 4/3 instead of x to find y.
y=-(4/3)+5
y= 11/3.

Use the binomial formula to find the coefficient of the q^4 p^17
term in the expansion of (29+p)^21
Answers
Recal the binomial theorem:
[tex]\displaystyle (a+b)^n = \sum_{k=0}^n \binom nk a^{n-k} b^k[/tex]
Then
[tex]\displaystyle (2q+p)^{21} = \sum_{k=0}^{21} \binom{21}k (2q)^{21-k} p^k = \sum_{k=0}^{21} \binom{21}k 2^{21-k} q^{21-k} p^k[/tex]
We get the q⁴p¹⁷ term when k = 17, and its coefficient would be
[tex]\dbinom{21}{17} 2^{21-17} = \dfrac{21!}{17!(21-17)!} 2^4 = \dfrac{21\cdot20\cdot19\cdot18}{4\cdot3\cdot2\cdot1}\cdot2^4 = \boxed{95,760}[/tex]
An operation is defined as p*q=-5q+p2 evaluate. 2*(7*3)
Answers
Answer:
- 166
Step-by-step explanation:
First step is to evaluate 7*3
7*3 ( with p = 7 and q = 3 )
= - 5(3) + 7²
= - 15 + 49
= 34
Now evaluate
2*34 ( with p = 2 and q = 34 )
= - 5(34) + 2²
= - 170 + 4
= - 166
Question 11 Objective: Solve for unknown side lengths of right triangles using trigonometric ratios. A right triangle has one angle that measure 27. The adjacent leg measures 29.6 cm and the hypotenuse measures 40 cm. What is the approximate area of the triangle? Round to the nearest tenth. Area of a triangle = 1/2bh а
Answers
Answer:
A≈ 268.76 sq cm.
Step-by-step explanation:
sine 27 = opposite side/hypotenuse
sine 27 = x/40
sin 27(40) = x
18.15961999 =x
18.16 = x
A = 1/2(29.6)(18.1596199)
A = 268.7623759
A≈ 268.76 sq cm.
