Answer:
Step-by-step explanation:
Subtract 4x from both sides
4x-4x + 2y = -4x - 12
2y = - 4x - 12
Divide by 2
2y/2 = -4x/2 - 12/2
y = -2x - 6
The y intercept happens when x = 0
y intercept is - 6
or 0,-6
Answer:
y intercept = -6
x intercept = -3

Which geometric figure does not have rotational symmetry?
A. trapezoid
B. equilateral triangle
C. regular pentagon
D. rectangle
Answer:
A. trapezoid
Step-by-step explanation:
A trapezoid does not have rotational symmetry . It would have to rotate 360 degree to look the same
An equilateral triangle has 120 degree rotational symmetry
A regular pentagon has 72 degree rotational symmetry
A rectangle has 180 degree rotational symmetry
What is the value of c, d, a, and b?
Answer:
a=101
b=67
c=84
d=80
Step-by-step explanation:
The measure of an intercepted arc will always be twice the measure of the inscribed angle
to find A:
2(100)=a+99
200=a+99
a=101 degrees
d=80 degrees because 100*2=200, 360-200=160, and 160/2=80
You can find c by subtracting 100, 96, and 80 from 360 and you get c=84 degrees
Find the measure of b by using what you found as measure of c and a
2(84)=101+b
168=101+b
b=67
Answer:
By the inscribed angle theorem, the measure of inscribed angles is half the measure of its intercepted arc, the inscribed angle measuring 100°.
Intercepts the arc measuring [tex](a+99)^{o}[/tex] so:
[tex]100=1/2(a+99)[/tex]
[tex]200=a+99[/tex]
Subtract 99 from both sides
[tex]a=101[/tex]
By the corollary 3 of the inscribed angle theorem, the opposite angle of a quadrilateral inscribed in a circle are supplementary so:
[tex]c+96=180[/tex]
Subtract 96 from both sides
[tex]c=84[/tex]
and, [tex]d+100=180[/tex]
[tex]d=80[/tex]
The inscribed angle measuring c° intercepts the arc measuring (a+b)° so:
[tex]c=1/2(a+b)[/tex]
[tex]84=1/2(101+6)[/tex]
[tex]168=101+b[/tex]
[tex]b=67[/tex]

Please help me find x
Need help fast!!
Answer:
x = 100°
Step-by-step explanation:
p and q are parallel lines. Construct line 'l' parallel to p and q
a = 30° {p// l when parallel lines are intersected by transversal alternate interior angles are congruent}
c +110 = 180 {linear pair}
c = 180 - 110
c = 70°
b= c {q // l when parallel lines are intersected by transversal alternate interior angles are congruent}
b = 70°
x = a + b
x = 30° + 70°
x = 100°

Tyrone measured the floor of his rectangular storage unit. It is 3 feet wide and 8 feet from one corner to the opposite corner. How long is the storage unit? If necessary, round to the nearest tenth.
Answer:
Rounded to the nearest tenth, 7.4 feet long.
Step-by-step explanation:
Tyrone has a rectangular storage unit. We are given the width and the diagonal length.
So we can use Pythagorean Theorem.
3^2 + b^2 = 8^2
9 + b^2 = 64
subtract 9 from both sides
b^2 = 55
b = sqrt55
b is around 7.4161984871, so b rounded to the nearest tenth is 7.4 feet long.

Solve the square of this equation with explanation as I don’t understand please
===========================================================
Explanation:
Cut the x coefficient (10) in half to get 10/2 = 5. Then square this to get 5^2 = 25.
We'll add 1 to both sides so that the "24" turns into "25", thereby completing the square
x^2 + 10x + 24 = 0
x^2 + 10x + 24+1 = 0+1
x^2 + 10x + 25 = 1
Notice on the left hand side we have something of the form A^2+2AB+B^2 where A = x and B = 5. We can factor this into (A+B)^2, which is the whole reason why we completed the square. You can use the FOIL rule to see how (A+B)^2 expands out into A^2+2AB+B^2. Factoring reverses this process.
This means x^2+10x+25 factors to (x+5)^2 and we now have these steps
(x+5)^2 = 1
x+5 = sqrt(1) or x+5 = -sqrt(1)
x+5 = 1 or x+5 = -1
x = 1-5 or x = -1-5
x = -4 or x = -6 are the two solutions
------------------
Let's check x = -4 to see if it works or not
x^2 + 10x + 24 = 0
(-4)^2 + 10(-4) + 24 = 0
16 - 40 + 24 = 0
-24 + 24 = 0
0 = 0
We get a true equation. That confirms x = -4 is a solution.
If we tried x = -6, then,
x^2 + 10x + 24 = 0
(-6)^2 + 10(-6) + 24 = 0
36 - 60 + 24 = 0
-24 + 24 = 0
0 = 0
That x value is confirmed as well.

10. The slope of the line passing through (3, 3)
and (-3, 3) is:
Answer:
0
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= (3-3)/(-3-3)
= 0/-6
=0
Answer:
m = 0
Step-by-step explanation:
Use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
[tex]\frac{3-3}{3-(-3)}\\\\ \frac{0}{6}\\\\0[/tex]
Therefore, the slope of the line is 0.
*Note that if the y values do not change as x changes, it is evidence that the slope is 0.*

Identify the number as prime, composite or neither. If the number is composite, write it as the product of prime
factors.
18
Answer:
composite number
prime factors={2,3}
factors of 18={1,2,3,6,9,18}
❏ Hello there! ❏
This number is composite.
Prime numbers have only two factors.
An example of a prime number is 5 (it's divisible by itself and 1)
Every prime number is divisible by itself and 1 (only these two numbers)
Composite numbers, however, have 3 or more factors.
18 has more than 3 factors, therefore, it's composite.
Product of prime factors:
2*3*3
2 is prime, because it's divisible by itself and 1
3 is prime as well
Hope it helps you!

A purchase costs $25.79 plus a tax of $1.29. Find the sales tax rate.
Answer:
The sales tax rate is 5%.
Step-by-step explanation:
To determine the sales tax rate if you already know the amount of tax being added to the purchase price, divide the amount of tax by the purchase price. In this example, divide $1.29 (amount of tax being added) by $25.79 (purchase price). When you do that, you will see that the answer is 0.0500, or 5%.

what is the product of (3 + x) and (2x – 5)
Answer:
2x² + x - 15
Step-by-step explanation:
(3 + x)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3(2x - 5) + x(2x - 5) ← distribute both parenthesis
= 6x - 15 + 2x² - 5x ← collect like terms
= 2x² + x - 15
