Answer:
1) -3x + 5 = -10
-3x = -15
x= -15/-3
X = 5
3) 4-6x = -8
-6x = -8-4
-6x = -12
X = 2
2) 2(x-5)= -5
2x - 10 = -5
2x = 5
x = 2.5
4) -0.5(2x+6) = -6
-x -3 = -6
-x = -6+3
-X = -3 ( both negative will get cancel)
X = 3

determine whether or not the side lengths can be sides of a triangle 23, 16, 7
Answer:
The side lengths can not form a triangle
Step-by-step explanation:
Given
[tex]Sides: 23,16,7[/tex]
Required
Can the side lengths can form a triangle?
To do this, we apply triangle Inequality Theorem, which states that for sides a, b and c:
[tex]a + b>c[/tex] , [tex]c + b>a[/tex] and [tex]c + a>b[/tex]
In this case, we have:
[tex]23 + 16 > 7[/tex]
[tex]39 > 7[/tex] --- True
[tex]23 + 7 > 16[/tex]
[tex]30 > 16[/tex] --- True
[tex]16 + 7 > 23[/tex]
[tex]23 > 23[/tex] --- False
Hence, the side lengths can not form a triangle

By what factor is z multiplied to get z1?
Answer:
The correct answer is -2.
Step-by-step explanation:
"z" = 3+2i, which is (3, 2i) on the graph. You must multiply -2 by 3 and 6, which will give you the plot points for z1, (-6, -4i).
A negative number multiplied into a positive number will result in a negative number.
Therefore, -2 is the correct answer.

At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she have in her tip jar if she serves n more customers during her shift
Answer:
She has $20 + $0.50n in her tip jar.
Step-by-step explanation:
Amount in tip jar at noon = $20
Average amount made from each customer = $0.50
Number of additional customers served after noon = n
Therefore, we have:
Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n
Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n
Therefore, she has $20 + $0.50n in her tip jar.

is the equation a true statement when x equals -3 in other words is -3 a solution to the equation 6 x + 5 = 5x +8 + 2x explained? explain
Answer: Yes
Step-by-step explanation: bc 6(-3)+5=5(-3)+8+2(-3)
Becomes -18+5=-15+8+-6 which equals -13 on both sides meaning -3 is a solution
6x+5=5x+8+2x
6x+5=(5x+2x)+(8)(Combine Like Terms)
6x+5=7x+8
6x+5=7x+8
Step 2: Subtract 7x from both sides.
6x+5−7x=7x+8−7x
−x+5=8
Step 3: Subtract 5 from both sides.
−x+5−5=8−5
−x=3
Step 4: Divide both sides by -1.

g Find the equation of the line passing through the point (1, 1, 1) which is perpendicular to the plane containing the points (1, 0, 0), (2, 1, 1) and (1, 1, 2).
Answer:
The equation of the line is given by:
[tex]x = 1 + t[/tex]
[tex]y = 1 - 2t[/tex]
[tex]z = 1 + t[/tex]
Step-by-step explanation:
Parametrizing the equation of the line in function of t, the equation of the line is given by:
[tex]x = x_0 + at[/tex]
[tex]y = y_0 + bt[/tex]
[tex]z = z_0 + ct[/tex]
In which we have an initial point [tex](x_0,y_0,z_0)[/tex] and [tex](a,b,c)[/tex] is a vector parallel to the line.
Line passing through the point (1, 1, 1)
This means that [tex]x_0 = y_0 = z_0 = 1[/tex]. So
[tex]x = 1 + at[/tex]
[tex]y = 1 + bt[/tex]
[tex]z = 1 + ct[/tex]
Perpendicular to the plane containing the points (1, 0, 0), (2, 1, 1) and (1, 1, 2).
From this, we get two vectors:
[tex](2-1,1-0,1-0) = (1,1,1)[/tex]
[tex](1-2,1-1,2-1) = (-1,0,1)[/tex]
The parallel vector is given by the determinant of the following matrix:
[tex]\left[\begin{array}{ccc}i&j&k\\1&1&1\\-1&0&1\end{array}\right][/tex]
Which is:
[tex]D = i*1*1 + j*1*-1 + k*1*0 - k*1*(-1) - j*1*1 -i*1*0[/tex]
[tex]D = i - j + k - j[/tex]
[tex]D = i - 2j + k[/tex]
So the vector is (1,-2,1), and the equation of the line is:
[tex]x = 1 + t[/tex]
[tex]y = 1 - 2t[/tex]
[tex]z = 1 + t[/tex]
What is the x-intercept of the graph below?
Answer:
[tex] \huge \boxed { - 3}[/tex]
Step-by-step explanation:
The graph intercepts x-axis at (-3,0). Therefore x-intercept is - 3.
To find the x-intercept from graph, look where does the graph intercept x-axis at, and that is x-intercept. If the graph doesn't intercept of pass x-axis then there's no x-intercept.

The sum of three consecutive EVEN integers is is 138. Find the smallest integer.
Step-by-step explanation:
Let x be the smallest even integer.
Then (x + 2) and (x + 4) are the other even integers.
We have x + (x + 2) + (x + 4) = 138.
=> 3x + 6 = 138
=> 3x = 132
=> x = 44.
Hence the smallest integer is 44.

The equivalent value of the fraction is A = 1/3
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = p - q
when the value of p = 17/15
And , when the value of q = 4/5
On simplifying the equation , we get
A = 17/15 - 4/5
So , the left hand side of the equation is equated to the right hand side by the value of ( 17/15 - 4/5 )
A = ( 17/15 - 4/5 )
Taking the LCM of the denominators of the fraction , we get
A = ( 17 - 12 ) / 15
On simplifying , we get
A = 5/15
A = 1/3
Therefore , the value of A = 1/3
Hence , the fraction is A = 1/3
