can someone help me find the values of y and z?
Answer:
y= 134.5 and z= 44.5 :)
Step-by-step explanation:
6z-87=180
6z=267
267/6=44.5
180-44.5=134.5
Answer:
y=99, z=81
Step-by-step explanation:
the angle above y is corresponding to 81, so if you substitute 81 in that place then it'll be angles on a straight line;
81 + y =180
(add like terms)
y =180 - 81
=99.
thus, y is 99. Once you do that, y and z are on a straight line so you solve for x using the formula for angles on a straight line;
y + (6z - 87)
(substitute y with 99)
99 + 6z - 87 =180
6z + 12 =180
(add like terms)
6z =180-12
6z =168
(divide both sides by six)
6z /6= 168/6
z = 28
(then you solve everything that was in the bracket for z)
(6z - 87)
(substitute z with 28)
=6 × 28 - 87
=168 - 87
=81
therefore, y =99 and z =81

Step-by-step explanation:
hi! this is modus ponens. modus ponens is a form of assumption, and modus tollens denies the initial statement. modus ponens is like saying if A, then B occurs as well. if A is proven to be true, B must also be true. this makes sense in this situation because it says if an animal is a dog, then it barks (if A, then B). the animal barks, so it is a dog (A is true, so B must also be true).
hope this helps!

Question 2: A line includes the points (20, 18) and (15, 13). What is its equation in
slope-intercept form?
y =
Answer:y=x
Step-by-step explanation: 13-18=-5
15-20=-5
-5/-5=1 slope
Using point slope take the first point and that slope to find the slope intercept.
Y-18=1(x-20)
Y=x-2

Step-by-step explanation:
What is the equation of a line that passes through the point (-7,-8) and parallel to y=5/7x-5.
Answer:
The equation of the line that passes through the point (-7, -8) and parallel to the given line is y = 5/7·x - 3
Step-by-step explanation:
The coordinates of the point the line passes = (-7, -8)
The equation of the line the required line is parallel to is y = 5/7·x - 5
The slope of of the given line is therefore in slope and intercept form with the slope = 5/7 and the y-intercept = -5
The slope of a line parallel to another line are equal, therefore the slope of the required line = The slope of the given line = 5/7
The equation of the required line in point slope form is therefore;
y - (-8) = 5/7 × (x - (-7))
y + 8 = 5/7 × x + 5/7 × 7
y + 8 = 5/7 × x + 5
∴ y = 5/7 × x + 5 - 8 = 5/7 × x - 3
y = 5/7 × x - 3
The equation of the line that passes through the point (-7, -8) and parallel to y = 5/7x - 5 is y = 5/7·x - 3.
Write each equation in slope-intercept form of the equation of a line. Underline the slope and circle the y-intercept in each equation.

Step-by-step explanation:
2y–6=0
a. slope intercept form using y = mx + b
y = 6/2
y = 3
b. slope: use the slope intercept form: y = mx + b
slope = m = 0
c. y-intercept = (0,3)
Answer:
slope intercept form: y=3
the slope:0
the y-intercept(0,3)

The formula K= C + 273 is used to
convert temperatures from degrees
Celsius to Kelvin. Solve this formula
for C.
Answer:
c = k - 273
Step-by-step explanation:
solve for c: k = c + 273
flip the equation: c + 273 = k
add -273 to both sides: c + 273 + -273 = k + -273
answer: c = k - 273
