determine what doesn't lie in the domain of g(x)=square root 2x-7
For the function g (x) = √ 2 x - 7, the elements that are not included in the domain are ( - ∞, 3.5).
We are given a function:
g (x) = √ 2 x - 7
Now, we need to find what all does not lie in the domain of this function.
For this, we first need to find the domain of the function.
We know that, a square root cannot be negative.
So, we get that:
2 x - 7 ≥ 0
Add 7 to both the sides:
2 x - 7 + 7 ≥ 0 + 7
2 x ≥ 7
Divide both sides by 2:
2 x / 2 ≥ 7 / 2
x ≥ 3.5
Domain = x ≥ 3.5 = [3.5, ∞)
Elements not included in the domain = R - [3.5, ∞) = ( - ∞, 3.5)
Therefore, we get that, for the function g (x) = √ 2 x - 7, the elements that are not included in the domain are ( - ∞, 3.5).

Triangles XYZ and EFG are given and ΔXYZ≅ΔEFG by SAS. If YZ=2n−5, YX=2n−1, EG=n+8, and FG=n+5, then which of the following statements is true.
Answer:
ZY = 15
Step-by-step explanation:
ZY is congruent to GF, so you set the equation up as
2n-5 = n+5
+5 +5
-----------------
2n = n+10
-n -n
------------------
n = 10
After you get n, you plug it in to 2n-5 (ZY)
2(10)-5

15
ZY=15
What is HL? Trapezoid
Answer:
HL = 21
Step-by-step explanation:
HL is the midsegment of the trapezoid shown above. Thus, it follows that:
HL = (JK + GF)/2
JK = 12
GF = 2.5(JK) = 2.5(12) = 30
Plug in the values:
HL = (12 + 30)/2
HL = 42/2
HL = 21

Find the balance of the account.
$1600 at 5% for 1 year
This is simple interest btw. I also need a explanation too
Answer:
$1680
Step-by-step explanation:
I = 5%
P = $1600
period = 1 year
$1600 + 15% = $1680
Answer:
$1680.
Step-by-step explanation:
The interest for 1 year = 1600 * 5%
= 1600 * 0.05
= $80.
So the new balance = old balance + interest
= 1600 + 80
= $1680.

Given that,
AD is parallel to EC, BD is congruent to BC.
Solution,
Here,
[tex]\angle D=\angle C[/tex] = the reason for this is that the two angles are alternate interior angle. So, by alternate interior angle theorem [tex]\angle D=\angle C[/tex].
As [tex]\angle ABD=\angle EBC[/tex] = due to vertically opposite theorem
It means,
[tex]\triangle ABD \cong \triangle EBC[/tex] (angle-side-angle)
Hence, the correct option is (c).

What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The expressions are given below.
[tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1
Then By simplification, we have
x - 2 = 2⁴
x = 16 + 2
x = 18
√x² + 7 = 4
x + 7 = 4
x = -3
∛(1 - x) = -1
1 - x = -1³
x = 2
The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

7) What is the equation of a circle with the center (-8, 9) and the radius of 10?
Answer:
(x+8)² + (y - 9)² = 100Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)² + (y - b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given
Centre (-8, 9) where a = -8, b = 9
radius r = 10
Substitute into the formula to get the required equation;
(x-(-8))² + (y - 9)² = 10²
(x+8))² + (y - 9)² = 10²
(x+8)² + (y - 9)² = 100
Hence the required equation is (x+8)² + (y - 9)² = 100

Both have table of 2 in common so
3/4 is the simplest form
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
No. of remaining days = [tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex]
If the denominators are the same, you can directly do the working for the numerators while leaving the denominator alone.
[tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex] = [tex]\frac{6}{8}[/tex]
6 and 8 both have a common factor of 2, so we can further simplify this fraction.
[tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
Thus, he must drive for [tex]\frac{3}{4}[/tex] more days.
