Please help me!<br><br> ty :)

dalvyx [7]

Answer:

x intercept= (-3,0) y intercept= (0,3)

Step-by-step explanation:

for x intercepts, y should equal zero

for y intercepts, x should equal zero

x intercept: -x+0=3

-x=3

x=-3 (x,y)--> (-3,0)

y intercept: 0+y=3

y=3 (x,y)--> (0,3)

1. Jamie purchases gifts for three friends. She chooses a book for $12.80 and then finds two identical necklaces. Her budget is

Evgen [1.6K]

Step-by-step explanation:

(48 - 12.80)/2 = $17.6

250/6 ≈ 42 and more

485 - 319 = 166 more people

14.5x + 80 > 500
14.5x > 420
x > 420/14.5
x > 29

1.25x + 3 ≤ 28
1.25x ≤ 25
x ≤ 25/1.25
x ≤ 20 miles

6. <em>This seems a typo... 460 is likely $60</em>

60x + 145 ≤ 625
60x ≤ 625 - 145
60x ≤ 480
x ≤ 480/60
x ≤ 8 days

What is the interquartile for this set of data? 11,19,35,42,60,72,80,85,88

exis [7]

Answer:

55.5

Step-by-step explanation:

find the median - in this case it's 60

then group the upper and lower halves of the data:

(11, 19, 35, 42) 60 (72, 80, 85, 88)

now we find the medians of those sets:

35 + 19/2 = 54/2 =27

80 + 85/2 = 165/2 = 82.5

then subtract those two medians to find the interquartile:

82.5 - 27 = 55.5

Jeffrey calculated the slope between two pairs of points. He found that the slope between -5, 6 and -3, 2 is -2. He also found t

Cerrena [4.2K]

Answer:

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between -5, 6 and -3, 2

substitute the values in the formula

$m=\frac{2-6}{-3+5}$

$m=\frac{-4}{2}=-2$

step 2

Find the slope between (-1, -2) and (0, -4)

substitute the values in the formula

$m=\frac{-4+2}{0+1}$

$m=\frac{-2}{1}=-2$

step 3

Find the slope between (-3, 2) and (0, -4)

substitute the values in the formula

$m=\frac{-4-2}{0+3}$

$m=\frac{-6}{3}=-2$

therefore

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2
