Answer:
-4x + y = -20
Step-by-step explanation:
2x+2(2x-1)=4(x-5)+3(x+1) is x =
Answer:
x=15
Step-by-step explanation:
First, you get rid of the parentheses:
2(2x-1) is 4x-2
4(x-5) is 4x-20
3(x+1) is 3x+3
________________________________
2x+4x-2=4x-20+3x+3
6x-2=4x-20x+3x+3
6x-2=7x-20+3
6x-2=7x-17
6x=7x-15
-1x=-15 or x=15

Answer: 80
Step-by-step explanation:
First you split the shape into simple parts, and think about the measurements when you do so. Although you can't see my work, the way I split it is a rectangle that measures 8 by 4, and a rectangle that measures 8 by 6. You find the answer to these separately (32 and 48) and add them together (80).

Choose the representations or descriptions that model the relation provided in each item. For each relation, select all situations that apply.
x -2 0 2 4
f(x) 4 0 4 16
a The relation is a function.
b f( x) = -2 x
c f(4)= -2
d domain: {-2, 0, 2, 4}
e The relation is not a function.
f f( x) = x2
It is B and D because it is the only one that matches the input and outputs. D shows a perfect graph of the points while B shows the points themselves. They cannot be a linear function since they are not linear so it is not E or F.

What is the 28th term of the arithmetic sequence with a 1 = 4 and d= -2
Answer:
Step-by-step explanation:
tn = a + (n-1)*d
t28 = 4 + (27)*-2 27 because 27 = 28 - 1
t28 = 4 + - 54
t28 = 4 - 54
t28 = - 50
The number of boys and girls in a class are in the ratio 4 : 7. There are 15 more girls than boys. find the number of total students in the class
Answer:
The number of total students in the class is 55
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The number of boys and girls in a class are in the ratio 4: 7
∵ There are 15 more girls than boys
→ That means the difference between them is 15
∵ The difference between the terms of their ratio = 7 - 4 = 3
→ By using the ratio method
→ boy : girl : difference
→ 4 : 7 : 3
→ x : y : 15
→ By using cross multiplication
∵ x × 3 = 4 × 15
∴ 3x = 60
→ Divide both sides by 3
∴ x = 20
∵ y × 3 = 7 × 15
∴ 3y = 105
→ Divide both sides by 3
∴ y = 35
∵ x represents the number of boys
∴ The number of boys is 20
∵ y represents the number of girls
∴ The number of girls is 35
∴ The total number of students = 20 + 35 = 55
∴ The number of total students in the class is 55

Which expression is equivalent to 8c + 6 - 3c - 2 ?
A)5c + 4
B)5c + 8
C)11c + 4
D)11c + 8
Answer:
I believe the answer is 5c + 4.
Step-by-step explanation:
The first step in simplifying expressions like this is to combine the values with the same coefficient and rearrange them so that they are next to each other in the expression. When you do this, you also have to keep the operation that comes before it if possible. 8c + 6 -3c - 2 will be turned into 8c - 3c + 6 - 2. Now you can simplify the expression in different parts. 8c - 3c = 5c, and 6 - 2 = 4. Keep the addition operation in the middle and combine the numbers:
5c + 4.

Answer:
The second option, 2 is a prime number, but not odd
Step-by-step explanation:
A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.
x2-16= -2x - 1
Please help
Answer:
The solutions are -5 and 3.
Step-by-step explanation:
[tex]x^2 - 16 = -2x-1[/tex]
[tex]x^2 - 16 +2x+1=0[/tex]
[tex]x^2 +2x-15=0[/tex]
Factoring the quadratic expression:
[tex](x+5)(x-3)= x^2 +2x-15=0[/tex]
So,
[tex]x+5 = 0 \implies x =-5[/tex]
[tex]x-3 = 0 \implies x =3[/tex]
