Write the measurements for the angles.
Answer:
1: 45
2: 135
3: 45
4: 135
5: 60
6: 120
7: 60
8: 120
9: 75
10: 105
11: 75
12: 105
Step-by-step explanation:
1, 2, 3, and 4 and 9, 10, 11, and 12 can be solved using the vertical angle and supplementary angle rules. Vertical angles are always the same and supplementary angles always add up to 180. But to find 5, 6, 7, and 8, you need to find 5 using the rule where all the angles in a triangle add up to 180. Since we know the angles for 9 and 3, we can find the angle 5 and then we can finish finding the rest of the angles.

how do you solve 6x+104=16x+114
Answer:
x = -1
Step-by-step explanation:
6x + 104 = 16x + 114
First subtract 104 from both sides
Now you have:
6x = 16x + 10
Subtract 16x from both sides
-10x = 10
Divide by -10 on both sides and you get your answer
x = -1
Answer:
x = - 1
Step-by-step explanation:
First you wanna subtract 104 from both sides
6x + 104 - 104 = 16x + 114 - 104
you should get 0 on the left and 10 on the right
next you subtract 16x from both sides
6x - 16x = 16x - 16x + 10
you should get -10x on the left side and get 0 on your right
next you divide both side by -10
-10x ÷ -10 = 10 ÷ -10
the left should be 0 and the right should be -1
that's how i got the answer and I hope it helped !
6) In a true experimental design, the manipulated variable, or grouping variable is
and assignment to groups is
(choose the option in which both are correct)
called the
a) dependent variable; random
b) dependent variable; based on preexisting differences
c) independent variable; based on preexisting difference
d) independent variable; random
In a true experimental design, the manipulated variable, or grouping variable is independent variable; based on pre-existing difference.
What is the independent variable?The independent variable is the variable in an experiment that is manipulated by the researcher. It is assumed that the independent variable has a direct effect on the dependent variable. The dependent variable is the variable whose value is being determined in the experiment.
For example, you want to carry out an experiment to determine the effect of the hours spent reading for a test on the grade gotten on the grade. In this research, the independent variable is the hours spent reading and the dependent variable is the grade gotten. Different data on the hours studied would be collected.

find the value of B in the following equation if you know it goes through (-7,2). -7x+By=31
Hello!
[tex]\large\boxed{B = -9}[/tex]
Find "B" by plugging in the x and y values into the equation given:
-7x + By = 31
-7(-7) + B(2) = 31
49 + 2B = 31
Subtract 49 from both sides:
2B = -18
Divide both sides by 2:
2B / 2 = -18/2
B = -9

Mrs. Haley had 5/7 of a liter of salt water. She used 1/2 of a liter for an experiment. How much salt water does Mrs. Haley have left?
Mrs. Haley had
liters of salt water left
PLEASE HELP SOON!! :))
Answer:
Mrs. Haley had [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.
Step-by-step explanation:
Mrs Haley has salt = [tex]\frac{5}{7}\:liter[/tex]
Mrs Haley used salt = [tex]\frac{1}{2}\:liter[/tex]
We need to find how much salt is left?
[tex]Salt\: left = Total\: Salt - Salt\: used\\Salt\: left = \frac{5}{7}-\frac{1}{2}\\Salt\: left =\frac{5*2-1*7}{14} \\Salt\: left =\frac{10-7}{14} \\Salt\: left =\frac{3}{14}[/tex]
So, Mrs. Haley had [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.
(-8,7) and (x,9) given m=1/2
Answer:
x = -4
Step-by-step explanation:
put the quardinates in the slope formula and set it to 1/2 and solve by cross multiplying
9-7/x+8 = 1/2
2/x+8 = 1/2
4 = x+8
x = -4

plug in the answers to see which has an equal scale factor between mp and mt, and po and tr
if tr = 6, then the scale factor between po and tr is 1.5
that means, that in order to equal 9 mt would have to be 3
if mt = 3, then the scale factor between mp and mt would also be 1.5
therefore, since they both have an equal scale factor, the answer is
4) TR = 6

Answer:
3rd and 4th options
Step-by-step explanation:
(12)
(f + g)(x)
= f(x) + g(x)
= x - 2 + 5x - 1 ← collect like terms
= 6x - 3
(13)
(g • f)(x)
= g(x) × f(x)
= - 3x(6x² - 3x) ← multiply each term in the parenthesis by - 3x
= - 18x³ + 9x²
