Answer:
2
Step-by-step explanation:
sum of angles in a triangle is 180
(26x - 2) + 70 + 60 = 180
26x -2 = 180 - 70 - 60
26x - 2 = 50
26x = 52
x = 2
hope this helped
Answer:
D) 2
Step-by-step explanation: The interior angles of triangles will ALWAYS add up to 180 degrees. In this case 2 angles are already provided, 70 and 60, so adding those together (130) the remaining angle must be 50 (180-130=50). In 26x-2=50, x=2 is the only possible answer. (Feel free to ask any questions if you don't understand anything I said!)
PLS HELP ME 12x - 15 = 6 - 3x
Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)
Answer:
x= 21/15
if you need to reduce it would be x=7/5
Step-by-step explanation:
12x-15 =6-3x
add 3x to both sides
15x- 15 = 6
now add 15 to both sides
15x = 21
lastly divide both sides by 15
x= 21/15
if you need to reduce it would be x=7/5
Answer:
x = 7/5 or 1.4
Step-by-step explanation:
12x - 15 = 6 - 3x Need to move one variable term to the other side to
+3x + 3x isolate it on one side
---------------------------
15x - 15 = 6 need to +15 to isolate the variable term
+15 +15
-----------------------
15/15x = 21/15 (simplify 21/15 = 7/5) need to divide by 15 to isolate x
------------------------
x = 7/5 or 1.4

what are the equalities of f(x)=loga(x)
A. f(1)=0
B. f(a)= 1
C. f(0)=0
D. f(1/a)=-1
9514 1404 393
Answer:
A, B, D
Step-by-step explanation:
For appropriate values of 'a', the log function has the following characteristics:
A: f(1) = 0B: f(a) = 1D: f(1/a) = -1Any log function will tend toward negative infinity as x tends to zero (for |a|>1).

need help solving to complete the square
Answer:
b=9 and b=-21
Step-by-step explanation:
first step: move 195 to the other side by adding to get:
b^2+12b=189
now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36
b^2+12b+36=189+36
next factor b^2+12b+36.
(b+6)^2=225
square root both sides to get:
b+6=15 and b+6=-15
solve by subracting 6 to both sides and you get the 2 final answers.
b=9 and b=-21

Find the gradient of the line segment between the points (-2,3) and (-4,-2).
Give your answer in its simplest form.
Given:
The two points are (-2,3) and (-4,-2).
To find:
The gradient of the line segment between the given points.
Solution:
The gradient is also known as slope.
The slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is
[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]
[tex]m=\dfrac{-5}{-4+2}[/tex]
[tex]m=\dfrac{-5}{-2}[/tex]
[tex]m=\dfrac{5}{2}[/tex]
Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].

Find the area of a triangle with a base of 10 inches and a height of 5 inches
Answer:
area = 25 in^2
Step-by-step explanation:
area = 1/2(10)(5) = 25 in^2
Answer:
The height is 4 inches.For a triangle, we have Area = 1/2 base times height.
With a = area, b = base and h = height,
we have:
A=1/2bh
We are told that A=10 square inches and b=5 inches, so we need to solve (find h ) for:
10=1/2(5)h
We can get rid of the fraction by multiplying by 2 on both sides:
20=5h
Now divide noth sides by 5 (or multiply by 1/5 , to get
20/5=5h/5 so 4=h
The height is 4 inches.

Actually Welcome to the Concept of the inequalities.
===> -7 + 45m - 35 < 9m - 11
===> 45m - 42 < 9m - 11
===> 45m - 9m < -11 + 42
==> 36m < 31
==> m < 31/36
hence the value of m < 31/36
Answer:
m = 31/36
