Answer:
43°
Step-by-step explanation:
the blue angle is congruent with the 80° because they are vertical angles
the red angle is 57° because 123° and 57° angles are supplementary angles
the green angle is 43° because the sum or angles in a triangle is 180°

The force (F) needed to cause the acceleration (a) of an object of mass, m, is given by the equation, F=ma where m is the object’s mass. If a 12-Newton force causes the object to accelerate to 3 m/s2, what is that object’s mass? The unit for this mass is kg.
Answers
From Newton’s Second Law of Motion, the force needed to accelerate a moving object of mass m at acceleration a is given by ;
F = ma
In this case, m = 5kg, a = 6m/s^2 and we want to find F
F = 5 x 6
F = 30N
Therefore, a force of 30N is needed to accelerate a 5kg object at 6m/s^2.

Answer:
f(x) = - (x + 3)² + 12Step-by-step explanation:
The vertex form:
f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola and a- the leading coefficientWe have on the graph:
(h, k) = (-3, 12)Substitute into equation:
f(x) = a(x - (-3))² + 12 = a(x + 3)² + 12Use the point (0, 3) to find the value of a:
3 = a(0 + 3)² + 123 = 9a + 129a = 3 - 129a = - 9a = -1So the function is:
f(x) = - (x + 3)² + 12You should know the __________ and ___________ of all safety equipment.

Answers
Answer:
Step-by-step explanation:
-2(x-4) =10x+2
-2x--8= 10x+2
-2x+8= 10x+2
-2x+10x= 8+2
8x= 10
x= 0.8
Answer:
Step-by-step explanation:
To solve for x you first isolate the variable you want on one side. We will do this by using PEMDAS and expanding our terms fully first before we move our terms around.
[tex]-2(x-4)=10x+2\\-2x-8=10x+2[/tex]
We then isolate our term, remember to add numbers and variables to both sides so you aren't changing the value of the equation, and solve for x.[tex]-2x-8=10x+2\\-2x-8-2+2x=10x+2-2+2x\\-10=12x\\\frac{-10}{12}=x\\\frac{-6}{5}=x\\-1.2=x\\[/tex]

Answer:
Equation of Parallel Line: y = -7x - 44
Equation of Perpendicular Line: y = x/7 - 8/7
Step-by-step explanation:
1) Parallel
Substitute (-6, -2) to find C
-2 = -7(-6) + c
-2 = 42 + c
-2 - 42 = c
c = -44
y = -7x -44
2) Perpendicular
Negative reciprocal
Substitute (-6, -2) to find C
-2 = 1/7(-6) + c
-2 = -6/7 + c
-2 + 6/7 = c
c = -8/7
y = 1/7x - 8/7 or
y = x/7 - 8/7

Solve for x. Remove the fractions first. 3/5(x-5)=-2/3
Answers
Answer:
x = 35/9 or 3 8/9
Step-by-step explanation:
removing the fractions implies using the distributive property, which is multiplying each term outside the parentheses by each term inside
in this problem, after distributing 3/5 we get:
3/5x - 3 = -2/3
we want to isolate the 'x' so we undo subtraction first by adding 3 to each side to get:
3/5x = 9/3 - 2/3
3/5 x = 7/3
x = 7/3 × 5/3
x = 35/9
3/5x = 7/3
we can get the 'x' by itself if we multiply each side by the reciprocal of 3/5, which is 5/3 to get:
x = 7/3 × 5/3
x = 35/3

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answers
Answer:
x = 12.2 mi
Step-by-step explanation:
Given the two sides of the right triangle:
a = 6.1 mi
b = 10.6 mi
c = x
Use the Pythagorean Theorem to solve for the value of the hypotenuse, x:
c² = a² + b²
c² = (6.1)² + (10.6)²
c² = 37.21 + 112.36
[tex]\sqrt{(c^{2})} = \sqrt{ 37.21 + 112.36 }[/tex]
[tex]\sqrt{(c^{2})} = \sqrt{ 37.21 + 112.36 }[/tex]
c = 12.2 mi
Therefore, x = 12.2 mi

1. Vinay applied the distributive property to the equation -5(m - 2) - 25. His equation then became --5m + 10 = -125. Did he apply the distributive property correctly?
Explain
Yes. When using the distributive property you need to multiply all the terms in the equation by the number that is in front of the parentheses.
No. The product of -5 and 25 is 125, not - 125.
No. Vinay also multiplied the right-hand side of the equation by --5, which is incorrect.
Yes. Vinay multiplied the terms on the left-hand side of the equation by -5, which is what you are supposed to do.
Answers
Answer:
C. No. Vinay also multiplied the right-hand side of the equation by --5, which is incorrect.Step-by-step explanation:
Proper application of the property:
- 5(m - 2) - 25 = -5m - 5(-2) - 25 = -5m + 10 - 25 = -5m - 15Vinay multiplied 5 and 25 as well, which is incorrect.
Correct answer choice is C.
