Answer:
im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*
Step-by-step explanation:
reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3
i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle and that would be your answer

assume that y varies directly as x. if y=7 when x=4, find y when x=12
Answers
y = 21
Step-by-step explanation:
since y = 7 as x = 4, therefore, when x = 12, y = 21
Think about it. if you divide 7 by 4, you get 1.75 and if you divide 21 by 12, you get 1.75. That means that from 4 to 12, I multiplied by 3, so therefore, y = 21.

Answers
Answer:
The correct answer is option D
Step-by-step explanation:option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (wrong option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12/x (corect option)( I meant to switch it around)
The general form of inverse variation between the variables x and y is as following:

What is the axis of symmetry for f(x) = 2x2 − 4x + 5? x = −2 x = −1 x = 1 x = 2
Answers
Step-by-step explanation:
for a quadratic equation
y = ax² + bx + c
the x value for the axis of symmetry is
x = -b/(2a)
in our case
y = 2x² - 4x + 5
a = 2
b = -4
x = - -4/4 = 4/4 = 1
x = 1 is the correct answer.

The low temperature on a certain day is 51°F. The low temperature is 17°F lower than the high temperature, h.
Which equation can be used to find the high temperature for that day?
51 = 17h
51 = h + 17
51=h−17
h + 51 = 17
Answers
You’re trying to find a certain high temperature. You know that the low is 51°, which is 17° lower than the high temperature(h). With this information, you can find that h=68 (51+17). To get from 68° to 51°, you would subtract 17°. Making the equation 51=h-17.

Answer:

Step-by-step explanation:
x needs to be any number greater than 5, as you can see, this is an inequality not an equation so there is no defenite answer. if youdo the math, 10+-5 is 5, our answer cannot equal 5 it has to be greater than 5, Therefore, x can be any number greater than -5
Kara has five exam scores of 93, 67, 82, 71, and 94 in her biology class. What score does she need on the final exam to have a mean grade of 80?
Round your answer to two decimal places, if necessary. (All exams have a maximum of 100 points.)
Answers
Answer:
She needs at least 73%
Step-by-step explanation:
1. add all of the numbers up and d the quantity to find
93+67+82+71+94/5
=407/5
=81.
2. try diffrent numbers
407+73/6
=480/6
=80
She needs at least 73%
Answer:
A score of 73
Step-by-step explanation:
Five exam scores + the final exam = mean (average) of 80.
First find the total points that you need to make an 80 average 80 × 6 = 480 points.
The five exam scores + x score = 480 points.
93 + 67 + 82 + 71 + 94 + x = 480
407 + x = 480
x = 480 - 407
x = 73

x=15 or x=35
x cannot be 15 because 15-23 is a negative answer
