€800 with 50% = €400. €600 with 30%=€420
Answer:
x > 3
Step-by-step explanation:
Given
2(4 + 2x) < 5x + 5 ← distribute left side
8 + 4x < 5x + 5 ( subtract 5 from both sides )
3 + 4x < 5x ( subtract 4x from both sides )
3 < x ⇒ x > 3
Answer:
<em>The slope of line
is
</em>
Step-by-step explanation:
Line
has the slope
and is perpendicular to line ![LM](https://tex.z-dn.net/?f=LM)
Suppose, the slope of line
is ![m](https://tex.z-dn.net/?f=m)
We know that, the <u>product of the slopes of two lines which are perpendicular to each other is always
</u>. So, the equation will be..............
![\frac{3}{4}*m= -1\\ \\\frac{3m}{4}=-1\\ \\ 3m= -4\\ \\ m=-\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%2Am%3D%20-1%5C%5C%20%5C%5C%5Cfrac%7B3m%7D%7B4%7D%3D-1%5C%5C%20%5C%5C%203m%3D%20-4%5C%5C%20%5C%5C%20m%3D-%5Cfrac%7B4%7D%7B3%7D)
So, the slope of line
will be ![-\frac{4}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B3%7D)
Answer:
it would be 60%
Step-by-step explanation:
Answer:
F(4) = 23
Step-by-step explanation:
Find F(4) also means finf F = 4x + 7 when x =4
When x = 4, it would be:
F = 4*4 +7
F = 16 + 7
F = 23
F(4) = 23
