Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7
Answer:
The last one, Explanatory variable: player 40-yard-dash time
Response variable: player weight would be your answer. Hope this helps : )
Step-by-step explanation:
(5,36)(8,48)
slope = (48 - 36) / (8 - 5) = 12/3 = 4
y = mx + b
slope(m) = 4
(5,36)...x = 5 and y = 36
now sub and find b
36 = 4(5) + b
36 = 20 + b
36 - 20 = b
16 = b
equation is : y = 4x + 16.....in standard form : 4x - y = -16 <==
=======================
function notation : f(x) = 4x + 16
=======================
x axis will be ur hrs....I would label them at intervals of 1
y axis will be total cost of renting the bike......as far as the intervals...not sure how to label them.....sorry....I wanna say intervals of 2...but am not sure
y = 4x + 16
slope = 4
y int = (0,16)
x int = (-4,0)
so start at (-4,0)....and since ur slope is 4, go up 4 and to the right 1...keep doing this and u will cross the y axis at (0,16)
Answer:
2 shirts and 14 pants
why it is awnser
it is that because if u do 15×16 u get 240 and if u subtract 10 twice from that u get 220 so
subtract 16 from 2 and that gives u how many pants she bought and the 2 represents the shirts
We are given with an original equation of y = x where the slope is 1 and passes through (0,0). if the equation is translated by 8 units to the right, the line still has the same slope but now passes through (8,0).
y-y1 = m (x-x1)y - 0 = 1 (x-8)y = x - 8
The line now becomes y = x - 8
