Equation/Question:
-2(x+1)+4x<-10 What’s the solution?
Answer/Way I did it:
1. Expand.
-2x-2+4x<-10
2. Simplify -2x-2+4x to 2x-2.
2x-2<-10
3. Add 2 to both sides.
2x<-10+2
4. Simplify -10+2 to −8.
2x<-8
5. Divide both sides by 2.
x<-8/2
6. Simplify 8/2 to 4.
x<−4

Find the slope of the line with f(6) = -2 and f(-4) = 3
Answer:
m=-1/2
Step-by-step explanation:
f(6)=-2 is (6,-2) and f(-4)=3 is (-4,3)
the equation for slope (m) is (y2-y1)/(x2-x1)
label the points:
x1=6
y2=-2
x2=-4
y2=3
now substitute into the equation:
m=(3--2)/(-4-6)
m=5/-10
m=-1/2
the slope is -1/2
hope this helps!
Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
Kylie is 24 years old
Step-by-step explanation:
kylie = x
Bobby=x-5
x+x-5=43
2x-5=43
2x=43+5
2x=48
X=24 years old
19
If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

Actually Welcome to the Concept of the Similarities.
Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,
hence for,
1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3
hence the value of x is 12 , ===> x = 12 .
2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,
hence we apply the relation,
x = 2*4.5 ===> x = 9 units.
HELP ILL GIVE BRAINLYIST
Answer:
560
Step-by-step Explanation
Since, 476 students make 85%.
Therefore, let x students will make 100%.
[tex] \frac{476}{85} = \frac{x}{100} \\ \\ x = \frac{476 \times 100}{85} \\ \\ x = \frac{47600}{85} \\ \\ x = {560} [/tex]

W-20.5=8 please help me
This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.
We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.
w-20.5+20.5=8+20.5
w=28.5
Any questions just ask me in the comments of this question :)
Write the equation of a line with an undefined slope that passes through the point (-6,3)
Answer:
x = -6
Step-by-step explanation:
A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

During the economic downturn in 2008, the price of a stock, A(x), over an 18-month period decreased and then
increased according to the equation A(x) = 0.70x2 - 6x + 15, where x equals the number of months. The price of
another stock, B(x), increased according to the equation B(x) = 2.75x + 1.50 over the same 18-month period. State all
prices, to the nearest dollar, when both stock values were the same.

find the value of 9x+4y when x=4 and y=-3
Answer:
you substitute x for 4 and so you multiply 9 x 4 which will give you 36 and then you have to add four times y so you substitute y for -3 and you add 36 - 12 which will give you 24
