four times daphne's age plus five times isaac's age adds up to 57. also, isaac's age is 11 less than twice daphne's age. how old

Talja [164]

4d + 5i = 57
i = 2d - 11

4d + 5(2d - 11) = 57
4d + 10d - 55 = 57
14d = 57 + 55
14d = 112
d = 112/14
d = 8 <== Daphne's age

i = 2d - 11
i = 2(8) - 11
i = 16 - 11
i = 5 <==Isaac's age

Someone help me pls

Wittaler [7]

Answer:

y=1/2x + 3

Step-by-step explanation:

The first thing you need to know is that the slope of a perpendicular line is the opposite reciprocal of the other slope. Find the slope of this line, which is -2. The opposite reciprocal is 1/2. So, you know that the perpendicular line is equal to y=1/2x. Plug the x coordinate (4) in for x to have: y=1/2(4). Multiply 4 by 1/2 to get y=2. Since the y coordinate is supposed to equal 5, add 3 to y=2 to get 5. Since 3 is the amount we added, thats where the y intercept will be. Hope this helped!

Y=-2/3x+2 how to graph

Nikolay [14]

Step-by-step explanation:

Starting from y-intercept of [0, 2], you can either move two blocks north over 3 blocks west or two blocks south over three blocks east. Either way, you will still get this line because this is a negative rate of change [slope].
