Answer:
x = -2 5/14
Step-by-step explanation:
7(x + 6) + 7x = 9
First, open the parenthesis.
7x + 42 + 7x = 9
Combine like terms.
7x + 7x + 42 = 9
14x + 42 = 9
Subtract 9.
14x = -33
Divide.
x = -33/14
Simplify.
x = -2 5/14
Hope this helps!
Solve: 4n - 6 = 12
O n = 4
O n = -4
O n = 4.5
O n=-4.5
Answer:
4.5
Step-by-step explanation:
4n - 6 = 12
add +6 to both sides
4n = 18
divide by 4
4/4n = 18/4
n = 4.5

Graph the relation shown in the table. Is the relation a function? Why or why not?
Yes; no vertical line passes through two graphed points.
Yes; no horizontal line passes through two graphed points.
No; a vertical line passes through two graphed points.
No; a horizontal line passes through two graphed points.
Answer:
Im gonna say its C because if a vertical line passes through 2 graphed points of intersection it isn't a function sorry if I fail you. -Your Ally, Bill Cipher

I need help on number 6 and 7
Answer:
1. c=13
2. a=12
Step-by-step explanation:
We have to use the Pythagorean theorm
a^2+b^2=c^2
(5*5)+(12*12)=c^2
25+144=c^2
169=c^2
Now we have to square root 169 to find c
[tex]\sqrt{169}[/tex]
c=13
For this one we have to do c^2-b^2=A^2
(15*15)-(9*9)
225-81=a^2
144=a^2
[tex]\sqrt{144}[/tex]
a=12

3&4. using the diagrams, is there enough information given to prove that the triangles are congruent? if so, state the theorem you would use
5&6. name the third congruence statement that is needed to prove that ABC is congruent to XYZ using the given theorem
Answer:
3. There is enough information to prove that ΔABC and ΔDEF are congruent using the Angle-Side-Angle (ASA) congruency theorem
4. More information is required to prove that ΔGFH and ΔJKL are congruent
5. ∠B ≅ ∠Y
6. ∠A ≅ ∠X
Step-by-step explanation:
3. In triangle ΔABC, and triangle ΔDEF, we have;
Corresponding angles ∠A and ∠D are congruent
Corresponding angles ∠C and ∠F are congruent
Corresponding side in between the given angles [tex]\overline{AC}[/tex] and [tex]\overline{DF}[/tex] are congruent
Therefore ΔABC is congruent to ΔDEF by the Angle-Side-Angle (ASA) rule of congruency
4. The corresponding angles ∠F and ∠J in triangle ΔGFH and triangle ΔJKL are congruent as well as the corresponding adjacent sides to the given angles and the corresponding opposite sides to the given angles are congruent, however, there is not enough information to prove that the two triangles are congruent
The included angles, ∠H and ∠L between the sides congruent corresponding sides should be congruent or the other adjacent sides [tex]\overline{FG}[/tex] and [tex]\overline{JK}[/tex] to the congruent angles ∠F and ∠J should be congruent for the triangles ΔGFH and ΔJKL to be congruent
5. Given [tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, using the Angle-Angle-Side, AAS, rule of congruency, we have;
The angles adjacent to ∠C and ∠Z, and opposite to [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex], which are B and ∠Y are congruent
Therefore, we have;
∠B ≅ ∠Y using AAS rule of congruency
6. Using Angle-Side-Angle, ASA, rule, given;
[tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, then the angles on the other side of [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex] which are ∠A and ∠X should be congruent, we have;
∠A ≅ ∠X

What is the quotient of 3.12 x 108 and 2.6 x 105 expressed in scientific notation?
Answer:
1.2 * 10^3
Step-by-step explanation:
3.12 * 10^8
=========
2.6 * 10^5
Start by doing 3.12 / 1.6 = 1.2 and that is the correct number of sig digs.
Now get the power on the 10. When dividing, the powers subtract.
10^(8 - 5)
10^ 3
The answer is 1.2 * 10^3
Danny has 11 1/4 cups of chocolate syrup. He is going to make chocolate sundaes for his friends. Each sundae will have 3/4 cup of chocolate. How many sundaes can Danny make?
Answer: Danny can make 15 sundaes from 11 1/4 cups of chocolate
Step-by-step explanation:
number of cups of chocolate syrup= 11 1/4 cups
For ever sundae, he decides to make, it will require 3/4 cup of chocolate
Number of sundae , Danny can make = number of cups of chocolate syrup /3/4 cup of sundae
= 11 1/4 / 3/4
45/4 x 4/3= 15 sundaes
Therefore, Danny can make 15 sundaes from 11 1/4 cups of chocolate

Answer:
11
Step-by-step explanation:
The future value of the account is given by the formula ...
A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years
Solving for t, we find ...
A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P
log(A/P) = 12t·log(1 +r/12) . . . . . . take logs
Divide by the coefficient of t, then fill in the numbers.
t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))
t ≈ 11.497
It will take about 11 years for the account balance to reach the desired amount.

Find x y and ABHG for brainliest
Answer:
because AB//EF//CD, using thales theorem in ABEF, we have:
[tex]\frac{12}{21}=\frac{15}{y}\\\\<=>y=\frac{15.21}{12}=26.25[/tex]
we also have: CD//EF//GH => using thales theorem in CDGH:
[tex]\frac{21}{x}=\frac{y}{10}\\\\<=>x=\frac{210}{y}=\frac{210}{26.25}=8[/tex]
with y = 26.25 => AB = 26.25 - 14 = 12.25
x = 8 => GH = 5.8 - 3 = 40 - 3 = 37
+) the perimeter of ABHG = AB + AC + CE + GE + GH + HF + DF + BD
= 12.25 + 12 + 21 + 8 + 37 + 10 + 26.25 + 15
= 141.5
