Answer:
[tex]d = \sqrt{13}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(7-4)^2+(-3-(-1))^2}[/tex]
[tex]d = \sqrt{(3)^2+(-3+1)^2}[/tex]
[tex]d = \sqrt{9+(-2)^2}[/tex]
[tex]d = \sqrt{9+4}[/tex]
[tex]d = \sqrt{13}[/tex]

Find the value of r so the line that passes through each pair of points has the given slope.
(5, 9), (r, –3), m = –4
The value of r is 8 for the points to have a slope of -4.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is also defined as the ratio of the rise and the run.
The slope is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the points are (5, 9) and (r, –3) and the slope is -4. The value of the unknown number will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
-4 = ( -3 - 9) / ( r - 5 )
-4r + 20 = -12
-4r = -32
r = 32 / 4
r = 8
Therefore, the value of r is 8 for the points to have a slope of -4.

Derek collects quarters that have the names of the 50 U.S. States on them. He has collected 13 different state quarters in 2.25 months. His grandfather is coming to visit him in 9 months, and he wants to show his grandfather his collection. If he continues collecting quarters at the same rate, will his collection be complete by the time his grandfather visits? Explain your answer.
Answer:
Yes, his collection will be complete by the time his grandfather visits
Step-by-step explanation:
Here, we want to know if his collection would be complete by the time his grandfather visits.
From the question;
he has collected 13 different quarters in 2.25 months
At the same rate, x different quarters will be collected in 9 months
Thus, mathematically;
x * 2.25 = 13 * 9
x = (13 * 9)/2.25 = 52
Thus, at this rate he would have collected 52 quarters in 9 months.
Since he has only 50 to collect, it means his collection would be complete by the time his grandfather visits
Which function inputs will result in a horizontal stretch of the function f(x) = x? Check all that apply. F f(StartFraction 3 Over two EndFraction x) f(x + 2) f f(StartFraction one-half EndFraction x) f(x – 3.2) f(x) f f(StartFraction 2 Over 3 EndFraction x)
Answer:
The correct options are;
3) f(1/2·x)
5) f(2/3·x)
Step-by-step explanation:
The given parameter is presented here as follows;
f(x) = x
Therefore;
f(x) = y = x
Comparing with the general equation for a straight line, y = m·x + c, we have;
For y = x, m = 1
∴ The slope = 1
1) For f(3/2·x) = y = 3/2·x, the slope, m = 3/2 which is a steeper slope than m=1 and therefore a has more increase in y than in x values or has a vertical stretch rather than a horizontal stretch
2) For f(x + 2) = y = x + 2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
3) For f(1/2·x) = y = 1/2·x, the slope, m = 1/2 which is a gentler slope slope than m=1 as y increase half unit, for each unit increase in x and the function is horizontally stretched
4) For f(x - 3/2) = y = x - 3/2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
5) For f(2/3·x) = y = 2/3·x, the slope, m = 2/3 which is a gentler slope slope than m = 1 as y increase 2/3 unit, for each unit increase in x and the function is horizontally stretched.
