Answer:
[tex] - 30(x + 5) = 7x - 7 \\ - 30x - 150 = 7x - 7 \\ 7x + 30x = - 150 + 7 \\ 37x = - 143 \\ x = \frac{ - 143}{37} \\ x = - 3.864[/tex]
________o____o_____
30–(x+5)=7x-7
30 – x–5 =7x -7
7x+x = 30-5+7
8x = 32
x= 32/8
x=4

Write an absolute value inequality for the graph below. Use x for your variable.
Answer:
|x| ≥ 7
Step-by-step explanation:
Taking the absolute value means that any value of x will always be positive, meaning that the absolute value of -7 or less would be 7 or greater, which satisfies the inequality above and line graph.
Absolute value is 7 or greater.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
p ≠ q means that p is not equal to qp < q means that p is less than qp > q means that p is greater than qp ≤ q means that p is less than or equal to qp ≥ q means that p is greater than or equal to qAs, absolute value means that any value of x will always be positive.
So, the absolute value according to -7 or less would be 7 or greater,
Hence, absolute value is 7 or greater.

write a polynomial in standard form with the zeros –4 0 1 and 4
Step-by-step explanation:
Hi there!
Zero of the polynomial is the value of "X" that gives final answer as zero.
So, as the polynomial in the second gives zero every time when we keep the zero which are given in the question. It is the answer.
Check:
• x⁴ - x³ - 16x² + 16x
(-4)Keep the value -4 as the value of X in polynomial.
= (-4)⁴-(-4)³ -16*(-4)²+16*(-4)
= 256+64-256-64
= 0
0Keep the value 0 as the value of X in polynomial.
= (0)⁴-(0)³ -16*(0)²+16*(0)
= 0-0-0+0
= 0
1Keep the value 1 as the value of X in polynomial.
= (1)⁴-(1)³ -16*(1)²+16*(1)
= 1-1-16+16
= 0
4Keep the value 4 as the value of X in polynomial.
= (4)⁴-(4)³ -16*(4)²+16*(4)
= 256 - 64-256+64
= 0
Therefore, the correct answer is option B.

Find the value of n. olease help
Step-by-step explanation:
(-3n-13)+(n-369)=360degrees
-3n-13+n-369=360degrees
-3n+n-369-13=360degrees
-2n-382=360 degrees
-2n=(360+382)degrees
-2n=742
n=742 divided by - 2
= - 371
[tex]\\ \rm\longmapsto -3n-13=n-369[/tex]

Select all solutions to the equation (2x — 4)(x + 5) = 0.
x = -1/2
x = 1/2
x = -2
x = 2
x = -5
x = 5
Answer:
(2x-4) (x+5)=0
2x(x+5) -4(x+5)=0
2x^2+10x-4x-20=0
2x^2+6x-20=0
x^2+3x-10=0 ( Taking common of 2 )
x^2+(5-2)x-10=0 • (3=(5-2)x)
x^2+5x-2x-10=0
x(x+5)-2(x-5) =0 • Taking common
(x+5)(x-2) =0
so x=-5 or x=2.
The solutions to the equation (2x — 4)(x + 5) = 0 will be negative 5 and 2. Then the correct options are D and E.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equation is given below.
(2x - 4)(x + 5) = 0
The factors (2x - 4) and (x + 5) will be zero. Then we have
2x - 4 = 0
2x = 4
x = 4/2
x = 2
Then the other solution to the equation will be
x + 5 = 0
x = -5
The solutions to the equation (2x — 4)(x + 5) = 0 will be negative 5 and 2. Then the correct options are D and E.

1.3/4 part of number of students are girls and 120 students are boy. how many student are there altogether *
Answer:
159 students.
Since all you need to do is multiply 120×1.3/4=39, then you add 120, as we are told that there are 120 boys. Basically, there are 39 girls and 120 boys, since by multiplying 20×1.3/4 equals 39, so 39 girls, and 120 boys. Now add them all together, 120+39=159.

the length of rectangular ground is 18m longer than its breadth and its perimeter is 124 find its length and breadth
Answer: length is 22m and breadth is 40m.
Step-by-step explanation:
breadth = b
length = 18+b
so
perimeter of rectangle = 2(l+b)
124 = 2(18+b+b)
or, 124 = 36 + 4b
or, 124-36 = 4b
or, b = 88/4 = 22m
so
l = 18 + b
= 18+22
= 40m

The points A,B and C have coordinates (2,1), (b,3) and (5,5), where b>5 and angle ABC = 90 degrees. Find b.
Answer:
b=6
Step-by-step explanation:
modul of the vector AB= sqrt((b-2)^2+(3-1)^2)= sqrt (b^2-4b+8). It is the length of the side AB
modul of the vector BC is equal to sqrt ((b-5)^2+(-2)^2)= sqrt (b^2-10b+29)
modul of the vector AC is sqrt ((5-2)^2+(5-1)^2)= 5
squared modul of AB + squared modul of BC = squared modul of the vector AC.
b^2-4b+8+b^2-10b+29=25
2b^2-14b+12=0
b^2-7b+6=0
b=1 b=6
b>5, s0 b=6
