-3x - 5y = -7
-4x + 5y = 14
Answer:x=-1, y=2
Step-by-step explanation:
Summing these equations, we will obtain,
-7x =7
Therefore, x=-1
If we put x in the first equation,
(-3*-1)-5y=-7
3-5y=-7
-5y=-10
y=2
Answer:
x=-1, y=1
Step-by-step explanation:
-3x-5y=-7
-4x+5y=14
-7x=7
x=-1
-3x-5y=-7
-3(-1)-5y=-7
3-5y=-7
-5y=-10

Which value of a in the exponential function below would cause the function to stretch? (one-third) Superscript x 0. 3 0. 9 1. 0 1. 5.
Using exponential functions, it is found that a = 1.5 would cause the function to stretch.
The exponential function given is:
[tex]y = \left(\frac{1}{3}\right)^x[/tex]
If it is multiplied by a such that |a| < 1, it is compressed.If it is multiplied by a such that |a| > 1, it is stretched.Hence, a = 1.5 would cause the function to stretch.

how to find inflection points from first derivative
Answer:
For finding the inflection points you'll have to put the first derivative equal to zero and solve for x. After you've done that, you can plug in the x you've just found into the original function and find also the y, so you'll find the ordered pair (x,y) of the inflection point(s).

Find the zeros of this polynomial:
p(x)= (x²+4x+3)(x²-4)
====================================================
Explanation:
Set each factor equal to zero and solve for x. I'm using the zero product property which says A*B = 0 leads to either A = 0 or B = 0.
Let's apply that idea to the first factor.
x^2+4x+3 = 0
(x+1)(x+3) = 0
x+1 = 0 or x+3 = 0
x = -1 or x = -3 are two roots
-------------
Do the same for the other factor as well.
x^2 - 4 = 0
(x-2)(x+2) = 0 .... difference of squares rule
x-2 = 0 or x+2 = 0
x = 2 or x = -2 are another two roots
--------------
In total, the four roots are:
x = -3x = -2x = -1x = 2Side note: The term "root" is the same as the zeros of a polynomial. Visually, this corresponds to the x intercepts. Plugging any of those four items into p(x) will lead to p(x) = 0.

A distance of 6.5 × 10−8 is multiplied by 10. The result is written in scientific notation. What is the new exponent?
Answer:
6.5 x 10^(-7)
Step-by-step explanation:
When multiplied by 10, it is like multiplying by 10^1. We can use the exponent rule: 10^(-8) * 10^1 = 10^(-7).
Example:
1.3 x 10^2 multiplied by 10
This is the same as 130 multiplied by 10 which is equal to 1300.
1300 written in scientific notation is 1.3 x 10^3, which adds one more onto the exponent.

Half of the marbles in a box are red, a third are white, and the other 6 are blue. Find the probability of picking a marble that is not blue
The probability of picking a marble that is not blue is 5/6
The proportions of the balls are given as:
[tex]Red = \frac 12[/tex]
[tex]White = \frac 13[/tex]
[tex]Blue = 6[/tex]
The probability of picking a ball that is not blue is:
[tex]P(Not\ Blue) = P(Red) + P(White)[/tex]
So, we have:
[tex]P(Not\ Blue) = \frac 12 + \frac 13[/tex]
Rewrite the fractions as equivalent fractions
[tex]P(Not\ Blue) = \frac 36 + \frac 26[/tex]
Take LCM
[tex]P(Not\ Blue) = \frac {3 + 2}6\\[/tex]
Add 3 and 2
[tex]P(Not\ Blue) = \frac {5}6[/tex]
Hence, the probability of picking a marble that is not blue is 5/6
