<h3>
Answer: No, it is not a solution</h3>
Explanation:
Refer to the diagram below. The point (-4,3) marked in red is outside the blue shaded region. So it doesn't make both inequalities true, and therefore not considered a solution.
In contrast, a point like (-5,1) is a solution as it is in the shaded region.
Put another way, the set of all solution points must be below both the solid line and the dashed line. Points can be on the solid line, but must be adjacent to the blue shaded region. The fact (-4,3) is on the solid line doesn't count because its not below the dashed line.
Answer:
the last one is equal to the question....

Answer:
<h3>
The father is 40 and the daughter is 20.</h3>
Step-by-step explanation:
x - the present age of the daughter
2x - the present age of the fathter
x - 10 - the age of the daughter ten year ago
2x - 10 - the age of the fathter ten year ago
Father is older than his dauther, so:
2x - 10 = (x - 10) + 20
2x - 10 = x - 10 + 20
2x - 10 = x + 10 {subtract x from both sides}
x - 10 = 10 {add 10 to both sides}
x = 20
2x = 2·20 = 40
A=1/2(h)(3/4h)
A=3/8h²
h²=8/3(A)
h=√8A/3

Answer:
(D)
Step-by-step explanation:
Slope : ( y2 - y1 )/( x2 - x1)
slope : ( -2 - 4 )/( - 3 + 4)
slope: ( -6 )/( 1 )
slope : -6
