write a linear function with f with f (5) = -1 and f (0) = -5
Answer:
5y = 4x-25
Step-by-step explanation:
Let f(x) be regarded as y
So we have two points
(5,-1) and (0,-5)
We start by finding the slope of the line connecting the two points
m = y2-y1/x2-x1
m = -5+1/0-5 = -4/-5 = 4/5
The general equation of a straight line is;
y = mx + b
where m
is slope and b is the y-intercept
we already have the slope as 4/5
So;
y = 4x/5 + b
To get b, substitute one of the points
Let us use (0,-5)
-5 = 4(0)/5 + b
so b = -5
The equation is;
y = 4x/5 - 5
Multiply through by 5
5y = 4x - 25
What is the slope ple

A man is walking 3 miles per hour toward point B
from point A. At the same time, a woman is
running 6 miles per hour toward point A from
point B. If point A and point B are 15 miles apart,
how far from point B will they meet?
E. 5 miles
F. 6 miles
G. 9 miles
H. 10 miles
PLEASE PLEASE HELP I NEED THIS ANSWER
Answer:
6 miles
Step-by-step explanation:
because the common denominator is 12 so the man will walk 12 miles in 4 hours and the woman will walk 12 miles in 2 hours so they will meet in the middle
If point A and point B are 15 miles apart, they will meet H) 10 miles from point B.
The answer to the question is H: 10 miles.
To solve this problem, we can use the concept of relative velocity. Relative velocity is the velocity of one object as seen by another object. In this case, the man and the woman are moving towards each other, so their relative velocity is the sum of their individual velocities.
The man's velocity is 3 miles per hour and the woman's velocity is 6 miles per hour, so their relative velocity is 3 + 6 = 9 miles per hour.
We know that point A and point B are 15 miles apart, so they will meet when the distance between them is 0. The time it takes them to meet is 15 / 9 = 5/3 hours.
In 5/3 hours, the man will travel 3 * 5/3 = 5 miles and the woman will travel 6 * 5/3 = 10 miles. Therefore, they will meet 10 miles from point B.

Answer:
The slopes of line segments AC and AD are same or constant i.e [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
We need to find slopes of AC and AD and tell if they are same or not.
The formula used to calculate slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Finding slope of AC
We have A=(3,2) and C=(0,1)
Finding slope using formula:
We have [tex]x_1=3, y_1=2, x_2=0,y_2=1[/tex]
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-2}{0-3}\\Slope=\frac{-1}{-3}\\Slope=\frac{1}{3}[/tex]
So, Slope of AC is [tex]\frac{1}{3}[/tex]
Finding slope of AD
We have A=(3,2) and C=(9,4)
Finding slope using formula:
We have [tex]x_1=3, y_1=2, x_2=9,y_2=4[/tex]
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4-2}{9-3}\\Slope=\frac{2}{6}\\Slope=\frac{1}{3}[/tex]
So, Slope of AD is [tex]\frac{1}{3}[/tex]
So, the slopes of line segments AC and AD are same or constant i.e [tex]\frac{1}{3}[/tex]

The value of [tex]y[/tex] will be [tex]4\sqrt{3}[/tex] .
What is triangle ?Triangle is a three sides two dimensional surface having three angles.
We have,
[tex]\triangle MRN[/tex] , [tex]\triangle RSM[/tex] and [tex]\triangle RSN[/tex],
And, [tex]NS =6,\ SM=2,\ RM=x,\ NR=y,\ RS=z[/tex]
Now,
We have right angle [tex]\triangle MRN[/tex],
Using Pythagoras theorem,
[tex]x^2+y^2=8^2[/tex]
[tex]x^2+y^2+=64\[/tex] [tex].....(i)[/tex]
Now, We have right angle [tex]\triangle RSN[/tex],
Again Using Pythagoras theorem,
[tex]z^2+6^2=y^2[/tex]
⇒[tex]z^2=y^2-36[/tex] [tex].....(ii)[/tex]
Now, We have right angle [tex]\triangle RSM[/tex],
Again Using Pythagoras theorem,
[tex]z^2+2^2=y^2[/tex]
⇒[tex]z^2=x^2-4[/tex] [tex].....(iii)[/tex]
Now comparing equation [tex](ii)[/tex] and equation [tex](iii)[/tex],
We get,
[tex]x^2-4=y^2-36[/tex]
We get,
[tex]x^2-y^2=-36+4[/tex]
[tex]x^2-y^2=-32[/tex] [tex].....(iv)[/tex]
Now,
Adding equation [tex](i)[/tex] and equation [tex](iv)[/tex], i.e.
[tex]x^2+y^2+=64[/tex]
[tex]x^2-y^2=-32[/tex]
We get,
[tex]2y^2=96[/tex]
[tex]y^2=48[/tex]
[tex]y=\sqrt{48}[/tex]
[tex]y=4\sqrt{3}[/tex]
So, the value of [tex]y[/tex] is [tex]4\sqrt{3}[/tex]
Hence, we can say that the value of [tex]y[/tex] will be [tex]4\sqrt{3}[/tex] which is given in option (b).

10) Cameron got 47 questions correct on a test that had 50 total questions. What percent of the questions
did Cameron get correct?
Answer:
Cameron scored a 94% on his test.
Step-by-step explanation:
47 / 50 = 0.94 x 100 = 94
For you to find the percentage, you need to divide 47/50, which ends up 0.94. After this, multiply by 100 so that you move the decimal place 2 times to the right. Thus, you get 94.

Which of the following statements would best represent the value of a? PLEASE HELP
Answer:
The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex] ⇒ c
Step-by-step explanation:
In the right angle triangle, we can use the trigonometry ratios to find the missing sides or angles
sin β = [tex]\frac{opposite}{hypotenuse}[/tex]cos β = [tex]\frac{adjacent}{hypotenuse}[/tex]tan β = [tex]\frac{opposite}{adjacent}[/tex]In the given right triangle
∵ There measure of an acute angle is 38°
∵ The adjacent side to this angle is a
∵ The opposite side to this angle is 6
→ We will use the tangent ratio because we have the opposite and
adjacent sides of the given angle
∴ tan(38°) = [tex]\frac{6}{a}[/tex]
→ Multiply both sides by a to cancel the denominator in the right side
∴ a · tan(38°) = 6
→ Divide both sides by tan(38°) to find a
∴ a = [tex]\frac{6}{tan(38)}[/tex]
∴ The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex]

Answer: No.
Reason: (-1, -3) is (x, y) so, let's find -1 on the X scale first. Alright, -1 is in the blue, which is a great start. Now, it's -3 on the Y portion. And when you graph that, it's not in the blue shaded area, so no, it's not a solution. (TIP: Solution is the Shaded Area)
