Answer:
Step-by-step explanation:
In order to combine like terms, you have to isolate x and y from one side of the equation.
<u>First, thing you do is remove parentheses.</u>
<u>Solve.</u>
<u>Then, you combine like terms.</u>
<u>Add/subtract the numbers from left to right.</u>
-8z+3.5z=-4.5z
<u>Rewrite the problem down.</u>
<u>Solve.</u>
4.5-1.5=3
- <u>Therefore, the correct answer is 7y+3-4.5z.</u>
I hope this helps, let me know if you have any questions.
Answer:
x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
Step-by-step explanation:
(x3 + 2x - 1) (x4 - x3 + 3)
= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3
= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
Answer:
Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
<h3>-4x-8>-20</h3>
<u>First, add by 8 from both sides.</u>
<u>Solve.</u>
-20+8=-12
<u>Rewrite the problem down.</u>
<u>Multiply by -1 from both sides.</u>
(-4x)(-1)<(-12)(-1)
<u>Solve.</u>
<u>Multiply the numbers from left to right.</u>
(-12)(-1)=12
4x<12
<u>Divide by 4 from both sides.</u>
4x/4<12/4
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
12/4=3
<u>x<3</u>
- <u>Therefore, the correct answer is D. x<3 (last option).</u>

Answer:
y = 3/5x + 62/5
Step-by-step explanation:
Equation of a line with two points is
m = y - y_1 / x - x _1
m = y_2 - y_1 / x_2 - x _1
Equating both
y - y_1 / x - x_1 = y_2 - y_1 / x_2 - x_1
Using what we are provided with
(-4 , 10)(16 , -2)
x_1 = -4
y_1 = 40
x_2 = 16
y_2 = -2
Imputing the values
10 - (-2) / 16 - (-4) = y - 10 / x - (-4)
10 + 2 /16 + 4 = y - 10 / x + 4
12 / 20 = y - 10 / x + 4
Lets cross multiply
12 ( x + 4) = 20(y - 10)
Open the brackets
12x + 48 = 20y - 200
12x + 48 + 200 = 20y
12x + 248 = 20y
Following this equation of line
y = mx + C
20y = 12x + 248
Let's divide through by 20 to get y.
20y / 20 = 12x + 248 / 20
y = 12x + 248 / 20
We can separate it by
y = 12x / 20 + 248 / 20
y = 3/5x + 62/5
Therefore, the equation of the line is
y = 3/5x + 62/5
Answer:
x + 61 = 411
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 61 = the number of student tickets sold
x + x + 61 = 761
2x = 700
x = 350
