Answer:

x = -2

Step-by-step explanation:

2x-4+x+10=0 combine like terms

3x + 6 = 0 subtract 6 from both sides

3x = -6 divide by 3

x = -2

Which gives the correct values for points A, B, C, and D?
saveliy_v [14]

Answer:

<em>The correct answer is: A</em>

Step-by-step explanation:

<u>Points on a Numeric Line</u>

The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.

Point A is clearly on the -2 mark, thus

A=-2

Point B is one mark above A, thus it's located at:

B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}

B=-1\frac{3}{4}

Point C is one mark below -1, thus:

C=-1-\frac{1}{4}=-1\frac{1}{4}

Finally, point D is one mark below 0:

D=-\frac{1}{4}

The correct answer is: A

riangle XYZ is translated 4 units up and 3 units left to yield ΔX'Y'Z'. What is the distance between any two corresponding point
tester [92]

Answer:

5 units

Step-by-step explanation:

According to the given statement  Δ XYZ is translated 4 units up and 3 units left to yield ΔX'Y'Z' which means that each point in ΔXYZ is moved 4 units up and moved 3 units left.

To find the distance of each corresponding point we will use the Pythagorean theorem which states that the square of the length of the Pythagorean of a right triangle is equal to the sum of the squares of the length of other legs

The square of the required distance = 4^2+3^2 = 16+9 =25

By taking root of 25 we get:

√25 = 5

Thus, we can conclude that the the distance between any two corresponding points on ΔXYZ and ΔX′Y′Z′  is 5 units. ..

Solve the equation below using a graphing
UNO [17]

Answer:

<em>x = 0.05</em>

<em>x = 1.57</em>

Step-by-step explanation:

The given equation is:

e^x-\ln 2x = 3.7

Moving all terms to the left side:

e^x-\ln 2x - 3.7=0

Now we define a function:

y=f(x)=e^x-\ln 2x - 3.7

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57
