Answer:
x = 8 or x = -8
Step-by-step explanation:
Solve for x over the integers:
-abs(x) = -8
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides by -1:
abs(x) = 8
Hint: | Eliminate the absolute value.
Split the equation into two possible cases:
Answer: x = 8 or x = -8

Answer:
h=9cm
P=(x+5)cm
b=(x-3)cm
by the Pythagoras theorem,
h^2=p^2+b^2
9^2=(x+5)^2+(x-3)^2
81=x^2+10x+25+x^2-6x+9
81=2x^2+4x+34
Factor: 5x2 – 15x – 20
(a) 5(x-4)(x+1)
(b) -2(x-4)(x+5)
(c) -5(x+4)(x-1)
(d) 5(x+4)(x+1)
Answer:
A.
Step-by-step explanation:
5x^2 – 15x – 20
= 5(x^2 – 3x – 4)
= 5(x^2 – 4x + x – 4)
= 5{x(x - 4) +1(x - 4)}
= 5(x-4)(x+1)

What is the GCF of x2 and x9?
Answer:
x²
Step-by-step explanation:
Given the values x² and x^9
The greatest common factor is the factors common to two or more compared values :
Factors of :
x² = x * x
x^9 = x * x * x * x * x * x * x * x * x
Multiplying the Factors in both are : x * x = x²
Similarly :
___|x² | x^9
_ x | x | x^8
_ x | 1 | x^7
There is no factor which can reduce both further simultaneously, Hence the G. C. F = (x * x) = x²
Use inductive reasoning to determine the next two terms in the sequence 7, 16, 34, 70
Answer: 142 and 286
==========================================
Explanation:
If we multiply a given term by 2, then add 2, we get
7*2+2 = 14+2 = 16
16*2+2 = 32+2 = 34
34*2+2 = 68+2 = 70
So the rule seems to be "multiply by 2, then add 2"
If that rule holds up, then the next two terms are
70*2+2 = 140+2 = 142
142*2+2 = 284+2 = 286

PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of seconds after the golf ball is hit. What is the height of the golf after 2.5 seconds? F 156 ft. G 84 ft. H 150 ft. J 136 ft.
Answer:
H. 150 ftStep-by-step explanation:
Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;
[tex]h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\[/tex]
Hence the height of the golf after 2.5 seconds is 150ft.

Irrational because its not an even number. If you try to do it you should get around 7.05
what is the opposite of 0.75
The opposite of 0.75 is -3/4.
What is Additive Inverse?To get a result equal to 0, add the original number and the additive inverse by simply changing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below.
Given:
we have 0.75
So, to find the opposite we have to find the additive inverse of 0.75
Then, the additive inverse of 0.75 is (-0.75).
Then, -0.75 = -3/4.
Hence, the opposite is -3/4.

A plane took 3h 33 min to finish a journey.if the distance of the journey was 2840 miles
Answer:
The plane was traveling at 800 mph
Step-by-step explanation:
Step 1: Find the total number of minutes flown by airplane
3 hours * 60 minutes/hour = 180 180 + 33 = 213 total minutes
Step 2: Divide the number of miles flown by the number of minutes
2840 miles / 213 minutes = 13.3333333 miles/minute
Step 3: Multiply the number of miles/minute by 60 to calculate the number of miles/hour
13.3333333 miles/minute * 60 minutes/hour = 800 miles/hour
Greatest 3 digit multiple of 33 using 3 diffrent digits
Answer:

Write the contrapositive of the given conditional statement.
Conditional Statement: "If a shape has four sides, then the shape is a rectangle."
Answer:
"If the shape is not a rectangle, then the shape doesn't has four sides."
Step-by-step explanation:
Given conditional statement is,
" Is a shape has four sides, then the shape is a rectangle."
Here we have two statements:
Statement p → A shape has four sides
Statement q → The shape is a rectangle.
Contrapositive of the statement will be:
If [tex]\sim q[/tex] then [tex]\sim p[/tex].
Therefore, contrapositive will be,
"If the shape is not a rectangle, then the shape doesn't has four sides."

Lm (51 + m) + 21² (m - 3) + 6L (m² +L)
Answer:
Step-by-step explanation:
Given :
l + m + n = 9
l²+ m² + n²= 31
l + m + n = 9
On squaring both sides
(l + m + n)²= 9²
(l²+m²+n²+2(lm+mn+nl) = 81
31 +2(lm+mn+nl) = 81
2(lm+mn+nl) = 81 - 31
2(lm+mn+nl) = 50
(lm+mn+nl) = 50/2
(lm+mn+nl) = 25
Hence, the value of (lm+mn+nl) = 25

90°, that is all the other angles so it would be 40° and 50°
Step-by-step explanation:
I hope this helps you :)
Answer:
40 degrees
Step-by-step explanation:
the three angles of a triangle must add to 180 and since it is an isosceles two angles must be equal therefore 180-100=80 to be divided by 2.
