Answer:
<h2>h=8</h2>
Step-by-step explanation:
we know
9h=81-9
let's do 81-9 first
81-9= 72
so we know
9h=72
to get h on its own, divide everything by 9
h=8
Answer:
13 and 44
Step-by-step explanation:
let x and y be the 2 numbers with y < x , then
x - y = 31 ( add y to both sides )
x = y + 31 ( subtract 31 from both sides )
x - 31 = y → (1)
4y = x + 8 → (2)
substitute y = x - 31 into (2)
4(x - 31) = x + 8
4x - 124 = x + 8 ( subtract x from both sides )
3x - 124 = 8 ( add 124 to both sides )
3x = 132 ( divide both sides by 3 )
x = 44
substitute x = 44 into (1)
44 - 31 = y , then
y = 13
the 2 numbers are 13 and 44

Answer:
Step-by-step explanation:
Given y=-1/2x-3, rewrite this as y = (-1/2)x - 3 for greater clarity.
x-intercept: Let y = 0 and find x: 0 = (-1/2)x - 3, or
(1/2)x = 3, or x = 6. Thus, (6, 0) is the x-intercept.
y-intercept: Let x = 0 and find y. Then (-1/2)(0) - 3 = y. Thus, y = -3, and the y-intercept is (0, -3).
Plot these two intercepts and then draw a line connecting them.
Example: To graph the y-intercept, start with your pencil point at the origin. Move your pencil point 3 units down and plot a dark dot there.
