Answer:
-108
Step-by-step explanation:
just multiply the numbers. it will be negative because there is odd number of negative sign so the profuct would be negative
7h+3s=27.95 subtract 7h from both sides
3s=27.95-7h divide both sides by 3
s=(27.95-7h)/3
Then we are told:
5h+4s=23.4, using s found above makes this equation become:
5h+4(27.95-7h)/3=23.4 multiply both sides by 3
15h+4(27.95-7h=70.2 perform indicated multiplication on left side
15h+111.8-28h=70.2 combine like terms on left side
-13h+111.8=70.2 subtract 111.8 from both sides
-13h=-41.6 divide both sides by -13
h=$3.20
Answer:
The graph of a relation must pass the vertical line test.
True
Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 5)² + (y - 7)² = 36 ← is in standard form
with (h, k ) = (- 5, 7 ) → B
On this graph, coordinate P lies 2 units to the left of the center. The side-to-side movement of a point on a coordinate plane is called movement on the x-axis, and since it is 2 units to the left of the center, it is called -2. All units to the left of the zero point (middle of the graph) is counted in negative numbers.
Coordinate P also lies 4 units down from the center. Movement up and down the graph is called movement on the y-axis, and since it is 4 units below the center, it is called -4. All units below 0 on the y-axis are counted in negative numbers.
To assemble our coordinates, we just have to remember the format for coordinates on a plane, which is (x, y). The value of the point's position on the x-axis always comes first, followed by its position on the y-axis. In this case, the finished coordinate would be (-2, -4).
Hope that helped! =)
