3) y = 4x + 24
y = x + 9
Answer:
x= -5
y= 4
Step-by-step explanation:
Substitute the equations for y
x+9=4x+24
Subtract x from both sides of the equation.
9=3x+24
Now subtract 24 from both sides of the equation.
-15=3x
x= -5
y= -5=9=4

if you play paintball for $8 for 30 minutes, how much will it cost you to play for 1 hour and 15 minutes?
please hurry! will give brainliest
Answer:
20
Step-by-step explanation:
30+30 is a hour and half of 30 is 15 so do this 8+8 and the add half of 8 and it is 4 so the full thing is 8+8+4+20
Which line has an x-intercept of 4?
4x+y=8
-4x + y= 8
2x+ 2y = -8
-2x+2y= -8
Answer:
-2x+2y=-8
-2x+2(0)=-8
-2x=-8
x=-8/-2
x=4
(4,0)
=======================================================
Explanation:
If we plug in y = 0 and solve for x, we'll get the x intercept.
Doing so for choice A has us get
4x+y = 8
4x+0 = 8
4x = 8
x = 8/4
x = 2
So the x intercept is 2. We can rule out choice A
Through similar steps, choice B has an x intercept of x = -2, so we can rule that out as well.
Choice C leads to x = -4, so that's not the answer either.
Choice D has an x intercept of x = 4 since,
-2x+2y = -8
-2(4)+2(0) = -8
-8+0 = -8
-8 = -8
So that confirms choice D is the answer.
Solve x4 - 11x2 + 18 = 0.
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3

For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicular, or neither.
10x - 3y = 3
3x + 10y = 30
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope of 10x - 3y = 3 is
(Type an integer or a simplified fraction.)
O B. The slope of 10x - 3y = 3 is undefined.
Answer/Step-by-step explanation:
Given,
10x - 3y = 3
3x + 10y = 30
Rewrite both equation in slope-intercept form, y = mx + b.
Where, m = slope of the line.
Thus,
✔️10x - 3y = 3
-3y = -10x + 3
y = 10/3x - 1
Slope of this line would be 10/3
✔️3x + 10y = 30
10y = -3x + 30
y = -3/10x + 3
The slope of this line is -³/10.
✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.

Answer:
4
Step-by-step explanation:
Since both of these numbers are negative, it means that the answer will be negative, since 2 negatives make a positive, since now you know that, you can easily do 32/8 which is 4.
-32/ -8 = 4
Check....
-8 * 4 = -32
-32 / 4 = -8
When there is a negative number and a positive number being multiplied or divided by, it will always result in a negative number.

there are 12 students in a class who are preforming at the school concert . this represents 40% of the class how many students are in the class?
Answer:
There are 30 students in class
Step-by-step explanation:
Let x be the total number of students
Then according to the given statement,
40% of x is 12
this can be expressed mathematically as:
[tex]12 = 40\%\ of\ x\\12 = 0.40 * x[/tex]
we can simply use this equation to find the total number of students
[tex]12 = 0.40x[/tex]
Dividing both sides by 0.40
[tex]\frac{0.40x}{0.40} = \frac{12}{0.40}\\x = 30[/tex]
Hence,
There are 30 students in class
