The point (-10,4) is on the graph of which of these functions? Select ALL that apply.
Answers
===========================================================
Explanation:
We'll plug x = -10 into each equation shown. If we get y = 4 as an output, then it is one of the answers.
------------------------------
A)
y = -x^2 + 6
y = -(-10)^2 + 6
y = -100 + 6
y = -94
We don't get y = 4, so we cross choice A off the list.
The point (-10,4) is not on y = -x^2+6. Instead, the point (-10,-94) is.
------------------------------
B)
y = (-1/2)*x - 1
y = (-1/2)*(-10) - 1
y = 5 - 1
y = 4
We can see that x = -10 leads to y = 4. The point (x,y) = (-10,4) is on the line. Choice B is one of the answers.
------------------------------
C)
y = (-1/10)*x - 3
y = (-1/10)*(-10) - 3
y = 1 - 3
y = -2
Choice C is not one of the answers since we want y = 4 as an output. So we can cross choice C off the list.
The point (-10,-2) is on the line instead of (-10,4)
------------------------------
D)
y = (1/10)x + 5
y = (1/10)*(-10) + 5
y = -1 + 5
y = 4
Choice D is one of the answers
------------------------------
E)
y = (1/5)*x^2 - 16
y = (1/5)*(-10)^2 - 16
y = (1/5)*(100) - 16
y = 20 - 16
y = 4
Choice E is one of the answers
------------------------------
An alternative method is to graph each equation and see if (-10,4) is on the curve or not. See the diagram below. Only choices B, D and E have (-10,4) on their respective curves.

Answers
Answer:
x = 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
(Linear pair angles)
(10x - 20 + 6x + 8)°= 180°
(16x - 12)°= 180°
16x - 12 = 180
16x = 180 + 12
16x = 192
x = 192/16
x = 12
Answer:
so x would equal 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
so you are going to want to combine like terms which would be
10x and 6x, and 20,8
10x+6x=16x
20-8=12
16x-12=180
now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side
which gets rid of the first 12
16x=180+12
now you can add 180+12
and you get 192
so now we want to get x by itself in order to do that you must divide
you are going to divide by 16 an each side and the 16 cancels out the first 16
16x/16=192/16
x=192/16
and 192 divided by 16 is 12
so you answer is
x=12
Hope this made sense :)

Answers
Answer:
x = 41
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
2x + 13 + x - 4 + x + 7 = 180, that is
4x + 16 = 180 ( subtract 16 from both sides )
4x = 164 ( divide both sides by 4 )
x = 41
Answer:
x=41
Step-by-step explanation:
we know that all the angles need to add up to 180
The angle on top is almost a right angle(90) but is not exactly
playing with the numbers will help
95-13=82/2=41
lets continue with this and see if it works out
41+7=48
41-4=37
48+95+37=180
hope this helps!
Which of these expressions is equivalent to log (92)? O A. log (2) • log (9) O B. log (2) – log (9) OC. log (2) + log (9) OD. 2 • log (9)
Answers
Correct question is;
Which of these expressions is equivalent to log (9^2)?
Answer:
D: 2•log 9
Step-by-step explanation:
From log rules, we know that;
log(a^n) = n•log(a)
Applying that rule to this question, we can simplify log (9^2) as;
log (9^2) = 2•log 9
Looking at the options, the correct one is Option D

Step-by-step explanation:

∠A+∠B+∠C=180
40+2X+X+2=180
X=46
∠B=46*2=92°
Answer: 92 degrees
Step-by-step explanation:
The exterior angle measuring 140 is equal to the sum of the two remote interior angles.
(X+2) + (2x) = 140. Combine like terms.
2 + 3x = 140. Subtract 2 from both sides.
3x = 138. Divide both sides by 3.
X = 46
Angle b = 2x. Substitute 46 in for x.
Angle b = 2(46)
Angle b = 92

Step-by-step explanation:
The area of the given triangle in the image is 74.8m².
What is a triangle?A triangle is simply a polygon with three vertices with three edges.
A scalene triangle is the triangle with no equal sides and angles.
It area can be calculated using the expression;
A = 1/2 × absinθ
Given the data in question;
Length of side a = 15mLength of side b = 11mLength of side c = 22mAngle C = 115°
To determine the area of the triangle, we substitute our given values into the expression above.
A = 1/2 × absinθ
A = 1/2 × 15m × 11m × sin( 115° )
A = 0.5 × 15m × 11m × 0.9063
A = 74.76975m²
A = 74.8m²
Therefore, the area of the given triangle in the image is 74.8m²
