Answer:
x=2
Step-by-step explanation:
First you put the equations in the form of y = mx + b
Then once they are like that it would look like:
y = -2x + 6
y = 3x - 4
So then you can set them equal to each other and it will look like this:
-2x + 6 = 3x - 4
Then you add 2x to both sides and get:
6 = 5x - 4
Next, add 4 to both sides and get:
10 = 5x
So then you will simplify by dividing both sides by 5 and getting:
2 = x
A company that makes hair-care products had 6,000 people try a new shampoo. Of the 6,000 people,
36 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
% of the people had a mild allergic reaction,
Answer:
0.6% of the people had a mild allergic reaction.
Step-by-step explanation:
Given that:
Number of people who tried hair care products = 6000
Number of people who had reaction = 36
Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{36}{6000}*100[/tex]
Percent of people = 0.6%
Hence,
0.6% of the people had a mild allergic reaction.
due in a few hours, i'll give brainliest to the correct answer!!!
Answer:
Angle a=45, Angle b=45
Step-by-step explanation:
The angles are complementary angles which means they both add up to 90 degrees. And if angles a and b are equal then its 90/2 which is 45.

Hey, I'm using edmuentum too, just so you know, you only have to do the tutorials unless you get the Mastery test wrong. I normally just skip through them and just get the questions wrong since the teachers can't see your answers on the tutorials. :) Anyways the answer is:
The first is growth by 25%
The second is decay by 25%
The third is growth by 100%
The fourth is growth by 1%
The last is decay by 1%
Consider this quadratic equation:
2x2+12=0
Comparing it to the standard form, name a, b, and c
a=
b=
c=
Answer:
a=2
b=0
c=12
Step-by-step explanation:
The standard form of a quadratic equation is ax²+bx+c=0
Here's the given equation:
2x²+12=0
You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.
The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2
12 has no variable, so that means it'll be c in the equation.
Hope this helps!

2. Draw a right triangle with side lengths of 6 centimeters, 8 centimeters,
and 10 centimeters, using a protractor to ensure that one angle is exactly
90°. Now make and cut out three squares; one with 6-centimeter long
sides, one with 8-centimeter long sides, and one with 10 centimeter long
sides. Place each square next to the corresponding sides of the triangle,
Which side is the hypotenuse in your diagram?
Answer:
the ten-inch side is the hypotenuse.
Step-by-step explanation:
[tex]a^{2}+ b^{2} =c^{2}[/tex]a= 6
b= 8
c= 10
use substitution to replace the variables in the equation, it should look like this:
36+64=100
the equation above is true, so the answer is that the 10-inch side is the hypotenuse.
*** I couldn't make a diagram on here, so I explained the math. hope this helps

Given that x is a nonnegative number, a student conjectured that x+3
Which value of x is a counterexample to the student's conjecture?
X= -1/3
X= -3
X= 2
X= 3
Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
Given
Conjecture: [tex]x + 3 < x^2[/tex] --- (Missing)
Required
Which value of x prove the conjecture otherwise
To do this , we simply substitute the values of x in the options
[tex]1.\ x = -\frac{1}{3}[/tex]
This is negative;
So, there is no need to check
[tex]2.\ x = -3[/tex]
This is also negative;
So, there is no need to check
[tex]3.\ x = 2[/tex]
[tex]x + 3 < x^2[/tex]
[tex]2 + 3 < 2^2[/tex]
[tex]5 < 4[/tex]
This value of x is false because 5 is not less than 4
[tex]4.\ x = 3[/tex]
[tex]x + 3 < x^2[/tex]
[tex]3 + 3 < 3^2[/tex]
[tex]6 < 9[/tex]
