So if her pay check is x she spends 0.25x on the dress and 0.125x on shoes. That’s 0.375 when added together.
So 0.375x + 24=60
0.375x = 60-24
0.375x= 36
X=36/0.375
X=$96
Answer:
D) x=
Step-by-step explanation:
The quadratic formula is :
A in terms of this question=9
B in terms of the question is 12
C in terms of the question is -24.
This question is an example of a quadratic equation. To work this out you may first need a calculator. The first step is to substitute the values of a,b and c into the formula. So once substituted the formula of becomes . Although when written in a calculator there will not be a plus and minus button and so you would have to do this separately.
However when substituting the values it would be best practice to put them in brackets.
1) Substitute the values into the equation for +.
2) Substitute the values into the equation for -.
Answer:
The correct option is:
A) L'' (-4 , -4) , M'' (-1 , -4) , N'' ( -1 , 0) , O'' (-4 , 0)
Step-by-step explanation:
The following are the vertices of a rectangle LMNO
L (-4 , 6)
M (-1 , 6)
N (-1 , 2)
O (-4 , 2)
First we have to reflect it across x-axis
When we reflect a shape across x-axis, the x components of the points remain the same while y components change their signs. After reflection:
L' (-4 , -6)
M' (-1 , -6)
N' ( -1 , -2)
O' (-4 , -2)
After we translate it up by two units, we add +2 to y components of each reflected point.
L'' (-4 , -4)
M'' (-1 , -4)
N'' ( -1 , 0)
O'' (-4 , 0)
Hence, the correct option is A
Answer:
Step-by-step explanation:
2)
x^3 - 3x^2 -24x +7
Find the derivative of this: which is,
3x^2 - 6x -24
in order to find the minimum you must set it up equal to 0
0 = 3x^2 - 6x -24
0 = 3(x^2 -2x -8)
0 = (x-4)(x+2)
x= 4
x=-2
Ignore the negative 2 answer, because it is unrealistic!
Hence, velocity is: 4 cm/sec
3) and 8) aren't visible, hence, i can't answer them
9) a. (-1,1/2) is where the f is both decreasing and concave down as shown in the graph down below.
Hope this helps!
Please mark brainliest if you think I helped! Would really appreciate!
The answer is 10x because two negatives make a positive so instead of subtracting, you add 7x+3x which is 10x
