An equation for the line whose slope is 4 and which passes thorough the point (-5,3)
Answers
Answer:
y = 4x + 23
Step-by-step explanation:
[tex]y-y_{1}=m(x-x_{1} )\\y-3=4(x-(-5))\\y-3=4(x+5)\\y-3=4x+20\\y=4x+23[/tex]
The equation of the line is required.
The equation of the line is [tex]y=4x+23[/tex]
Equation of line[tex]m[/tex] = Slope of line = 4
Point = [tex](-5,3)[/tex]
[tex]x_1=-5[/tex]
[tex]y_1=3[/tex]
Equation of a line is given by
[tex]y-y_1=m(x-x_1)\\\Rightarrow y-3=4(x-(-5))\\\Rightarrow y-3=4x+20\\\Rightarrow y=4x+20+3\\\Rightarrow y=4x+23[/tex]

if line p has a slope of 4/7, what is the slope of a line perpendicular to p?
(1). 4/7
(2). 7/4
(3). -4/7
(4). -7/4
Answers
Answer:
-7/4
Step-by-step explanation:
When you find the perpendicular slope, you take the opposite reciprocal of the original slope. For 4/7, the opposite is -4/7, and the reciprocal of that is -7/4.

Given:
A right angled triangle.
To find:
The value of x.
Solution:
We have,
Base = x
Hypotenuse = [tex]\sqrt{5}[/tex]
In a right angle triangle,
[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]
For the given triangle,
[tex]\cos 45^\circ= \dfrac{x}{\sqrt{5}}[/tex]
[tex]\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}[/tex]
Multiply both sides by [tex]\sqrt{5}[/tex].
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{10}}{2}= x[/tex]
Therefore, the required value of x is [tex]\dfrac{\sqrt{10}}{2}[/tex].

find the constant rate of change
Answers
Answer:
- 2 ft/ s
Step-by-step explanation:
The rate of change is the slope m of the line.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line
m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2
Rate of change is - 2 ft/ s

Answer:
48%
Step-by-step explanation:
If the coin is flipped 250 times, and lands on tails 120 times, set this up as a fraction. Put 250 on the bottom, and 120 on the top (because you want to know percentage of tails for 250 coin flips) to get 120/250. This is 0.48, to turn this into a percentage multiply by 100, 48%. You can check this answer by taking 0.48(250) and you will get 120.

Step-by-step explanation:
Just write the givens like this f(x) + g(x)
f(x) + g(x) = -7x + 1 + - 5x + 3
f(x) + g(x) = - 7x + 1 - 5x + 3

Find the value of x if 9^1/2 • 9^1/2 = x^√81
Answers
Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
