drag the ordered pair that are 5.5 units apart.
(-3, -3.5)
(5, 1.5)
(5, -3.5)
(-1.5, -3.5)
(-1.5, 2)
(-1.5, 2.5)
Answer:
(-1.5, -3.5) and (-1.5, 2)
Step-by-step explanation:
The x-coordinates in increasing order are ...
-3, -1.5, 5
The distances between pairs of these coordinates are ...
-1.5 -(-3) = 1.5
5 -(-3) = 8
5 -(-1.5) = 6.5
Clearly, any pair with x = 5 is too far away from any pair with a different x-value.
∆x = 1.5
If the distance between pairs is 5.5, then the distance formula tells us the y-coordinate differences for pairs with x-coordinates of -3 and -1.5 must be ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
5.5 = √(1.5^2 +(y2 -y1)^2) . . . substitute known values
30.25 = 2.25 +(y2 -y1)^2 . . . . square both sides
√28 = (y2 -y1) . . . . . . . . . . . . . . subtract 2.25 and take the square root
This value is irrational. Clearly none of the y-coordinates is irrational, so there are no point pairs with x-coordinates -3 and -1.5 that are 5.5 units apart.
__
∆x = 0
If the x-coordinates are the same, then the y-coordinates must differ by 5.5 in order for the points to be 5.5 units apart. The coordinates in order are ...
for x = -1.5, y = -3.5, 2, 2.5 . . . . . differences of 5.5, 6, 0.25
for x = 5, y = -3.5, 1.5 . . . . . . . difference of 5
The only pair we can find that is 5.5 units apart is ...
(-1.5, -3.5) and (-1.5, 2).

Answer and Explanation:
Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:
x = 4√(2)
y = 2(4) = 8
because where 4 = T,
x = T√2 and y = 2T
so again:
[tex]x = 4\sqrt{2}\\y = 8[/tex]
Answer:
B. 8.Step-by-step explanation:
All answers verified:
A. 5. Incorrect. 5 is not long enough for y.B. 8. Correct. Just the right size for y.C. 4. Incorrect. 4 is already in there, so this is incorrect.D. 2. Incorrect. Not even close to fit y.Your answer is B.
A ball is thrown from an initial height of 1 meter with an initial upward velocity of 11 m/s. The ball's height h (in meters) after t seconds is given by the following.
h=1+11t-5^2
Find all values of t for which the ball's height is 6 meters.
Round your answer(s) to the nearest hundredth.
Answer:
[tex]t=0.64[/tex] and [tex]t=1.56[/tex] seconds
Step-by-step explanation:
[tex]h=1+11t-5t^2\\\\6=1+11t-5t^2\\\\0=-5+11t-5t^2\\\\0=-5t^2+11t-5\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-11\pm\sqrt{11^2-4(-5)(-5)}}{2(-5)}\\\\t=\frac{-11\pm\sqrt{121-100}}{-10}\\ \\t=\frac{-11\pm\sqrt{21}}{-10}\\\\t=\frac{11}{10}\pm\frac{\sqrt{21}}{10}\\ \\t_1\approx0.64\\\\t_2\approx1.56[/tex]
Therefore, the values of t for which the ball's height is 6 meters is [tex]t=0.64[/tex] and [tex]t=1.56[/tex] seconds.

The football team gained 8 yards on the first play. Lost 6 yards on the next. Gained 3 yards on the
third play and lost 12 yards on their final play. What was their final change in yardage after the
four plays?
(HELPP)
Answer:
-7 yards
Step-by-step explanation:
Might help to line everything up
First play: gained 8 yards (+8)
Second play: lost 6 yards (-6)
Third play: gained 3 yards (+3)
Fourth play: lost 12 yards (-12)
Then put it all together and solve (I'll solve left to right):
(8-6)+3-12
(2+3)-12
5-12
-7
The final change in yardage was -7 yards

A line has 2/3 and y intercept -2 which answer is the equation of the line
Answer:
A line has a slope of 2/3 and y–intercept -2. The equation of the line is y = (2/3)x - 2.
Step-by-step explanation:
Hope this helps
Answer:
y = (2/3)x - 2
Step by step explanation:
The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.
Given, slope of the line is 2/3
y-intercept is -2.
The equation of the line in slope-intercept form is given by
y = mx + c
Where, m is the slope
c is the y-intercept.
y = (2/3)x - 2

What is the Y intercept and the slope of the equation Y=3-1/2x
Answer:
3
Step-by-step explanation:
y = 3 - 1/2x
rewrite equation so the slope is in front
y = -1/2x + 3
plug in 0 for x
y = -1/2(0) + 3
solve for y
y = 0 + 3
y = 3
y- intercept = (0,3)
Step-by-step explanation:
Since this equation is in slope-intercept form, we can easily identify what the slope is, and the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y intercept
Switch the coefficient and 3:
y = -1/2x + 3
-1/2 = Slope
3 = Y-intercept
Note: If we're asked to graph, using this equation will allow us to graph without solving.

C. (3, 0) (4, 1) (5, 2) (6, 3)
D. (-3, 0) (-4, 1) (-5, 2) (-6, 3)
Answer:
B. (0, 3) (1, 4) (2, 5) (3, 6)
Step-by-step explanation:
An ordered pair is (x, y). So the first number in the first ordered pair is x=0, or (0, _).
The value of y is 3 more than the value of x, so the first ordered pair is (0, 3). This matches answer choice B.
