Help please. Domain ASAP
Answer:
x ≥ -1
Step-by-step explanation:
The domain is all the possible x-values of the function.
Reading from left to right, the first x-value is x = -1 (which is included because the dot is filled in.) From there, the graph goes to the right, towards infinity.
So x is greater than or equal to -1.
x ≥ -1
If ∠AOB, ∠BOC, and ∠COD are supplementary angles, then what is the value of x and m∠COD?
A.
x = 20; m∠COD = 50°
B.
x = 20; m∠COD = 70°
C.
x = 50; m∠COD = 20°
D.
x = 30; m∠COD = 80°
Answer:
B
Step-by-step explanation:
x=180-90-20-50=20
m∠COD=20+50=70
Answer:
B
Step-by-step explanation:
∠ AOB + ∠ BOC + ∠ COD = 180° ( AOD is a straight line ) , then
20 + 90 + x + 50 = 180 , that is
x + 160 = 180 ( subtract 160 from both sides )
x = 20
Then
∠ COD = x + 50 = 20 + 50 = 70°

The area of triangle ABC is
square units.
Answer: Area = 17.5 unit²
Concept:
Here, we need to know how to calculate the area of a triangle.
Area (triangle) = b · h · (1/2)
b = base
h = height
Solve:
Given information (By counting grids on the graph)
b (AB) = 7
h (BC) = 5
Given expression
Area = b · h · (1/2)
Substitute values into the expression
Area = (7) · (5) · (1/2)
Simplify by multiplication
Area = (35) · (1/2)
Area = [tex]\boxed{17.5}[/tex]
Hope this helps!! :)

Solve 1/x = 1/a + 1/b find x
Answer:
[tex]x=\frac{ab}{a+b}[/tex]
Step-by-step explanation:
Combine the two fractions on the right by using the common denominator ab.
[tex]\frac{1}{x}=\frac{b}{ab}+\frac{a}{ab}\\=\frac{b+a}{ab}[/tex]
If two quantities are equal, then their reciprocals are equal.
[tex]x=\frac{ab}{b+a}[/tex]
Answer:
x = [tex]\frac{ab}{b+a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{x}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{1}{b}[/tex]
Multiply through by abx ( the LCM of denominators ) to clear the fractions
ab = bx + ax ← factor out x from each term on the left side
ab = x(b + a) ← divide both sides by (b + a)
[tex]\frac{ab}{b+a}[/tex] = x

Twenty-five percent of three dozen plants are blooming.
a. What fraction of the total number of plants are not blooming?
b. How many plants are not blooming?
Answer:
a. 3/4 b. 27
Step-by-step explanation:
We know 25% percent are blooming, since 100-25 = 75, 75% aren't blooming.
Since 1 / 4 = 0.25, 3/4 = 0.75, so for question a. 3/4 of the plants aren't blooming.
For question b, we know there are three dozen plants, which is 3 * 12 = 36 plants.
75% of 36 = 36 * 0.75 = 27 plants aren't blooming.
A particular brand of milk is sold in 1L and 2L bottles. If the shop owner orders 120L of milk and receives 97 bottles in total, calculate how many of each size the shop owner receives.
Answer:
74 1L bottles and 23 2L bottles
Step-by-step explanation:
We can use algebra to figure out the answer
let the 1L bottles be called m and the 2L bottles be called n
We know that:
(1) m+n = 97
and
(2) m+2n(2L bottles) = 120L
(2) - (1)
m+2n-m-n = 120-97
n = 23
and so
m = 74
Therefore, The shop owner receives 74 1L bottles and 23 2L bottles

How to find the absolute value of |2x+3|=13
Answer:
x=5 or x = -8
Step-by-step explanation:
|2x+3|=13
There are two solutions to this problem, one positive and one negative
2x+3 =13 and 2x+3 = -13
Subtract 3 from all sides
2x+3-3 = 13-3 2x+3-3 = -13-3
2x = 10 2x = -16
Divide each side by 2
2x/2=10/2 2x/2 = -16/2
x = 5 x = -8
The equation of a line in the point-slope form is show below. 4 – 9 = (x – 2) What is the slope of this line?
Answer:
undefined
Step-by-step explanation:
4 - 9 = x - 2
-5 = x - 2
-3 = x
this is a vertical line (parallel to the y-axis) at x = -3.
that means the slope of this line is "undefined". or some would call it "infinite".
as the slope is the ratio of y/x describing how many units y changes, when x changes a certain amount of units.
now the change of x for this line is constant 0.
so, we have a slope y/0, which is undefined.
Expand and simplify 5)3x+2)-2(4x-1)
Answer:
It is 7x + 12
Step-by-step explanation:
[tex]5(3x + 2) - 2(4x - 1)[/tex]
open brackets:
[tex] = 15x + 10 - 8x + 2[/tex]
group like terms together:
[tex] = (15x - 8x) + (10 + 2)[/tex]
factorise out x :
[tex] = x(15 - 8) + 12 \\ = 7x + 12[/tex]

x = -22/9 (when converted to decimal form, you get x = -2.44)
What is the sum of a rational number but a product of an irrational one.
I'm going to only focus on part B
If 'a' and 'b' are rational numbers, then
a = p/qb = r/swhere p,q,r,s are integers. Also, q and s are nonzero. In fact, this context would make sense to also have p and r to be nonzero as well.
The perimeter of this rectangle is
P = 2*(length+width)
P = 2*(a+b)
P = 2*(p/q + r/s)
P = 2*(ps/qs + qr/qs)
P = 2*( (ps+qr)/qs )
P = (2ps+2qr)/qs
P = integer/integer = some rational number
We see that the perimeter P is rational if and only if 'a' and 'b' are rational.
From this, notice that the area is
area = length*width = a*b = (p/q)*(r/s) = (pr)/(qs)
Showing that the area is also rational.
If we wanted the area to be irrational, then we'd have to have either 'a' and/or 'b' irrational; this would then make the perimeter irrational as well. This contradiction is sufficient to show that case B is not possible.
There is no way to have a rational perimeter but an irrational area.
