show me a Graph x=−4.
Answer:
The graph of line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
Step-by-step explanation:
Given the line
x=−4
The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.
As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
The graph of the line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,

What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given algebraic expression is 3z²− 6z.
The value of the expression at z = 5 is given as follows,
3z²− 6z
Substitute z = 5 to obtain,
3 × 5²− 6 × 5
= 75 - 30
= 45
Hence, the given expression can be simplified as 45.

Sissy wants to enlarge a picture of a constellation so that she can put it on the wall in her daughter’s room. What will be the area of the enlarged picture on the wall?
24 in.2
108 in.2
224 in.2
486 in.2
Answer: 486 in
Just did this on edge
The enlargement transformation applied to the rectangular figure gives
a rectangle that is enlarged and similar to the figure.
Correct response:
The area of the enlarged picture is 486 in.²The given dimensions of the picture are;
Height, [tex]\overline{MN}[/tex] = 6 in.
Width, [tex]\overline{LP}[/tex] = 4 in.
The length of QL' = 12 + 42 = 54
By similar triangles, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]
Which gives;
[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]
[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]
Given that an enlargement gives similar figures, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]
Therefore;
[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]
Which gives;
[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]
The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]
Which gives;
A = 27 × 18 = 486
The area of the enlarged picture on the wall is A = 486 in.²

The pair of figures is similar. Find x. Round to the nearest tenth if necessary.
A. 34 cm
B. 9.8 cm
C. 21.9 cm
D. 29.6 cm
Answer:
Choice B
Step-by-step explanation:
When two shapes are similar their sides are always going to be proportional. So here we will set up a proportion to solve this.
[tex]\frac{23}{40}=\frac{x}{17}[/tex]
Now we cross multiply
[tex]391=40x[/tex]
After we got an equation we solve it
[tex]x=9.775[/tex]
Since we got a decimal we will have to round it to the place they instruct for us, on this one it is 9.8 cm so it is choice b.
The required value of x is 9.8 cm. For the two similar triangles.
Two similar triangles are given. value of x to be determined.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Here, if triangles are similar then their ratio of sides is also equal.
x/23=17/40
x = 0.425*23
x = 0.425 * 23
x = 9.8 cm
Thus, The required value of x is 9.8 cm. For the two similar triangles.

Step-by-step explanation:
Average speed = 400 miles per hour
Distance = 400t
t= 5
Total distance = 400t at t hours
Total distance when t = 5 hours
Total distance travelled = 400t
= 400 × 5
= 2,000 miles
Total distance travelled = 2,000 miles
The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles

Chanelle deposits $7,500 into the bank. She does not withdraw or deposit money for 6 years. She earns 6% interest during that time. a. How much interest will she have earned at the end of 6 years? She will earn $2,700 interest b. What will the balance be when she is finally able to withdraw her money?
Answer: a. $2700
b. $10200
Step-by-step explanation:
a. The interest she would have earned at the end of the 6 years can be gotten using the formula
= PRT/100
= $7500 × 6% × 6
= $7500 × 6/100 × 6
= $7500 × 0.06 × 6
= $2700
b. Her balance when she wants to withdraw the money would be:
= $7500 + $2700
= $10200

Rita says they should the formula `d=rt`, where `d` is the distance traveled in miles, `r` is the rate of speed in miles per hour, and `t` is the time in hours.
Lumiere says they should use the equation `t=\frac{d}{r}` instead. Who is right? Explain.

The value for angle [tex]x[/tex] will be [tex]70^0[/tex] .
What is Angle ?Angle is when two rays meet together then the space between them is angle.
We have,
[tex]x=?[/tex]
A triangle with one of its angle equals to [tex]55^0[/tex] and two sides are equal .
So,
"When two sides are equal then the interior angles opposite to these lines are also equal".
So,
According to the above mentioned theorem the angle other than the angle [tex]x[/tex] will be [tex]55^0[/tex] .
Now, Using angle sum property,
[tex]x+55^0+55^0=180^0[/tex]
[tex]x=180^0-110^0[/tex]
[tex]x=70^0[/tex]
So, the value of [tex]x[/tex] is [tex]70^0[/tex] which is find out using the angle sum property.
Hence, we can say that the value for angle [tex]x[/tex] will be [tex]70^0[/tex] .
