Answer:
2x - y = - 5
Step-by-step explanation:
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 7) into the partial equation
7 = 2 + c ⇒ c = 7 - 2 = 5
y = 2x + 5 ← in slope- intercept form
The equation in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Subtract y from both sides
0 = 2x - y + 5 ( subtract 5 from both sides )
- 5 = 2x - y, that is
2x - y = - 5 ← in standard form
Answer:
x = ±11
Step-by-step explanation:
x^2 =121
Take the square root of each side
sqrt(x^2) = ±sqrt(121)
x = ±11
Answer:
$8 per foot
Explanation:
Diameter of the circular flowerbed = 7 feet
Radius of the circular flowerbed = 7/2 = 3.5 feet.
Since she wants to plant roses around the edge, we deal with the circumference.
Circumference of a circle = 2πr
Therefore:
If the total cost of planting roses is $176
The unit price of planting roses per foot
The unit price of planting roses is $8 per foot.
It looks like A {x|x > or = 0}.
But, your picture is blurry so it’s hard to see. If it’s a solid dot on the top left of the line and an arrow at the bottom right, then A is the correct answer. If that’s not what those are, sorry.
Answer:
draw a grid
Step-by-step explanation:
the slope is -4 by 3 which is usually put at y over x. you can draw a grid with -9 and 17 being put x by y then plot points on the graph which go down by 4 and go right by 3.
