Answer:
x=-6
Step-by-step explanation:
2x=-4-8
2x=-12
2x/2=-12/2
x=-6
Answer:
x = - 6
Step-by-step explanation:
2x+8 = 4
Subtract 8 from both sides:
2x+8-8 = - 4 - 8
Simplify :
2x = -12
Divide both sides by 2 :
2x/2 = -12/2
Simplify :
-12/2 : -6
x = -6

Find PUR, given the following sets:
P = {b, d, f, g}
Q = {a, b, c, d]
R = {c, e, f, g}
S = {a, d. g}
Answer:
={b,c,d,e,f,g}
Step-by-step explanation:
={b,c,d,e,f,g}
Answer:
PUR= b, d, f, g, c, e
Step-by-step explanation:
To fid the answer you unite the sets together. When uniting the sets you only write the letter once even if it appears in both sets.
So when we combine p and r the answer we get is:
PUR= b, d, f, g, c, e

2x + y = 10
x - 2y = -5
if (x,y) is the solution to the system of equations above, what is the value of 3x - y?
3x - y = 5
Step-by-step explanation:2x + y = 10 | ×2
x - 2y = -5
4x + 2y = 20
x - 2y = -5
add
4x + x + 2y - 2y = 20 - 5
5x = 15
x = 15 : 5
x = 3
replace x
4(3) + 2y = 20
12 + 2y = 20
2y = 8
y = 8 : 2
y = 4
3x - y =
= 3(3) - 4
= 9 - 4

Area of triangle = 1/2 × b × h
b = base and h = height
Area = 1/2 × (x+4) × (2)
Area = x + 4Area of rectangle = lb
l = Length and b = Breadth
Area = 10 (x + 2)
Area = 10x + 20
Given:The area of rectangle is 8 times greater than the area of the triangle.
Solution:According to the question,
10x + 20 = 8(x+4)
or, 10x + 20 = 8x + 32
or, 10x - 8x = 32 - 20
or, 2x = 12
or, x = 12/2 = 6
Answer:The value of x is 6.
Hence, Option D. 6 is correct.
Answer:
x = 6
Step-by-step explanation:
Area of rectangle = length * width
= 10 *(x +2)
= 10*x + 10*2
= 10x + 20 unit²
Area of triangle = [tex]\frac{1}{2}bh[/tex]
[tex]=\frac{1}{2}*2*(x +4)\\\\=1*(x+4)\\\\= x +4[/tex]
Area of rectangle = 8*area of triangle
10x + 20 = 8* (x+ 4)
10x + 20 = 8x + 32 {Subrtact 20 from both sides}
10x = 8x + 32 - 20
10x = 8x + 12 {subtract 8x form both sides}
10x - 8x = 12
2x = 12 {divide both sides by 2}
2x/2 = 12/2
x = 6

Carter is an election officer. On election day, he travels from his home to the polling place, which appears 8 inches away on a map of the county. What is the actual distance between Carter's home and the polling place if the scale of the map is 2 inches = 0.9 miles?
Answer:
3.6 miles
Step-by-step explanation:
since his house is 8 inches away and 2 inches =0.9miles
we just need to multiply. Divide 8 by 2 .
4× 9 = 36 so just add the decimal
0.9× 4= 3.6 miles

Find all excluded values for the expression. That is, find all values of x for which the expression is undefined.
x+6/x² - 6x-27
Answer:
The values of x for the expression is undefined is -3 or 9
Step-by-step explanation:
Given function,
[tex]f(x) = \frac{X +\ 6}{X^2 - 6X-27}[/tex]
The values of x for which the expression is undefined is obtained when the denominator is equal to zero, from the expression it is given by;
x² - 6x - 27 = 0
Factorize the equation
x² + 3x - 9x - 27 = 0
x (x + 3) -9(x + 3) = 0
(x + 3)(x - 9) = 0
x = -3 or x = 9
Therefore, the values of x for the expression is undefined is -3 or 9

1. What percent of 29 is 3?
Answer:
0.34%
Step-by-step explanation:
1. Start by representing the percentage with the variable, x %. Using x%, create an algebraic expression.
29% X x = 3
2. Solve for x by dividing both sides by 29.
29x divided by 29 =3 divided by 29.
x=0.1034
3.Convert 0.1034 into a percentage by multiplying the decimal by 100%
X =0.1034 x 100%
x=10.34%

Which statement is true? Question 7 options: A) |–3| = 3 and –|–4| = –4 B) |–3| = 3 and –|4| = 4 C) –|3| = 3 and |4| = 4 D) |–3| = 3 and |–4| = –4
Answer:
option A is correct
Step-by-step explanation:
mod's has a simple function -
if |x| is given it simply means that the value of "X" can't be negative
Option A is correct, |–3| = 3 and –|–4| = –4 is true statement.
What is Number system?A number system is defined as a system of writing to express numbers.
The absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign.
|-x|=x
For option A
|–3| = 3 and –|–4| = –4 is true
For option B
|–3| = 3 and –|4| = 4 is not true because –|4| is -4.
For option C
–|3| = 3 and |4| = 4 is not true because –|3| is -3
For option D
|–3| = 3 and |–4| = –4 is not true because |-4| is 4
Hence, option A is correct, |–3| = 3 and –|–4| = –4 is true statement.

Help me withis problem please I'm bad at math.
g(x) = f(x) - 5
We subtract 5 from f(x) because we are doing a vertical shift down 5 units.
Answer: A
Step-by-step explanation:
For this problem, you would need to analyze the graph.
If you notice, both lines look pretty identical with the exception of one lower than the other. As you can see, the blue line is the same as the red line, but shifted down by 5. Therefore, you would subtract f(x) by 5. That would make A our answer.
