Hello! Can someone please help me with this question ? I’ll mark brainly thanks ! :)
Answer:
[tex]\Large\boxed{\text{Perpendicular Equation:} \ y = -\frac{2}{7}x + \frac{22}{7}}[/tex]
[tex]\Large\boxed{\text{Parallel Equation:} \ y = \frac{7}{2}x -12}[/tex]
Step-by-step explanation:
In order to find the equations that are parallel/perpendicular to the line [tex]y = \frac{7}{2}x - 4[/tex], we need to note a couple things about the relationships between lines and their parallel/perpendicular lines.
A) If a line is perpendicular to another, the slopes will be opposite reciprocals (for instance [tex]-2[/tex] and [tex]\frac{1}{2}[/tex] - multiplied, they equal -1.)B) If a line is parallel to another, they will have the exact same slope.Perpendicular:We know that the slope of a perpendicular line will be the the opposite reciprocal of the line we're comparing it to.
Since the slope of our base line is [tex]\frac{7}{2}[/tex], we can find the reciprocal, then the opposite of that.
Reciprocal of [tex]\frac{7}{2} = \frac{2}{7}[/tex] Opposite of [tex]\frac{2}{7} = -\frac{2}{7}[/tex]So the slope of this line will be [tex]-\frac{2}{7}[/tex], making our equation [tex]y = -\frac{2}{7}x+ b[/tex]
However, y-intercepts will not stay the same. In order to find this, we can substitute the point (4, 2) into our equation to solve for b.
[tex]2 = -\frac{2}{7} \cdot 4 + b[/tex] [tex]2 = -\frac{8}{7} + b[/tex] [tex]b = 2+\frac{8}{7}[/tex] [tex]b = 2 \frac{8}{7}[/tex] [tex]b=\frac{22}{7}[/tex]Now we know the y-intercept of this equation is [tex]\frac{22}{7}[/tex]. We can now finish off our equation of the line by substituting that in to what we already have, [tex]y = -\frac{2}{7}x+ b[/tex].
[tex]y = -\frac{2}{7}x+ \frac{22}{7}[/tex]
Parallel:As mentioned earlier, parallel lines will have the exact same slope but not the same y-intercept. Since the slope of our original equation is [tex]\frac{7}{2}[/tex], the slope for this one will also be [tex]\frac{7}{2}[/tex].
So we now know the equation looks something like [tex]y = \frac{7}{2}x + b[/tex].
In order to solve for b, we apply the same logic we did in the perpendicular line and substitute in the point (4, 2) into the equation.
[tex]2 = \frac{7}{2} \cdot 4 + b[/tex] [tex]2 = \frac{28}{2}+b[/tex] [tex]2 = 14+b[/tex] [tex]b = 2-14[/tex] [tex]b =-12[/tex]Now that we know the slope and the y-intercept, we can finish off our equation as [tex]y = \frac{7}{2}x -12[/tex].
Hope this helped!
What is the equation of the line that passes through the point
Answer:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
an aquarium sells five stuffed animal for 64.95 what is the cost of eight stuffed animal
Answer: 103.92

1) just make an equation (answer below)
SO the new bottle is 30 ounces
The old bottle was 25 percent more then the new one
So we can just find 25 percent of 30
And add it
That is the most simple way but I would just do
30*1.25 Its the same thing but if you think a bout ti, the new bottle can Only hold 30 ounces, 30 ounces is 100 percent of the new bottle, if you multiply 1.25 its adding 25 percent so it Turns a 2 step into a 1 step.
1.25*30=37.5
The larger bottle was 37.5 ounces
PLEASE HELP IM DESPERATE! Which of these is equivalent to the expression s + s + s + s +12 ? ANSWER CHOICES: A. 4s + 3, B. 4(s + 3), C. 4s (s + 3), D. 4 + s + 12
Answer:
B
Step-by-step explanation:
s+s+s+s+12 = 20. s=2
4(s+3)
4(2+3)
4(5)=20
Hey there!
s + s + s + s + 12
= 1s + 1s + 1s + 1s + 12
= 2s + 2s + 12
= 4s + 12
So, we’re looking for something that’s equivalent to: 4s + 12
• Option A.
4s + 3 ≠ 4s + 12
Option A. is wrong because it is NOT equivalent to the given equation
• Option B.
4(s + 3)
= 4(s) + 4(3)
= 4s + 12
Thus, this mean Option B. could possibly be your answer.
• Option C.
4s(s + 3)
= 4s(s) + 4s(3)
= 4s(s) + 3(4s)
= 4s^2 + 12s
Option C. is wrong because it is NOT equivalent to the given equation as well.
• Option D.
4 + s + 12
COMBINE the LIKE TERMS
= 16 + s
= s + 16
Option D. is wrong because it isn’t equivalent to the given equation as well.
Therefore, your answer is:
Option B. 4(s + 3)
Good luck on your assignment & enjoy your day!

-1/4d-2/5d=39
Solve for d
Please explain I don’t understand
Answer:
d = -60
Step-by-step explanation:
Given:
-1/4d - 2/5d = 39
-5d-8d/20 = 39
-13/20d = 39
Divide both sides by -13/20
d = 39 ÷ -13/20
= 39 × -20/13
= -60
d = -60
