The linear equation y = -2x is passing through the origin. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y = -2x
The y-intercept in the above equation is zero. Then the linear equation is passing through the origin.
The linear equation y = -2x is passing through the origin. Then the correct option is B.

-5 1/2 + 7 3/4 value of the expression
Answer:
2 1/4
Step-by-step explanation:
-11/2+7 3/4
-11/2 + 31/4
= 9/4
= 2 1/4
Answer:
2 1/4.
Step-by-step explanation:
-5 1/2 + 7 3/4
= 7 3/4 - 5 1/2
= 7 - 5 + 3/4 - 1/2
= 2 + 1/4
= 2 1/4.
s congruent to . If angle S is (5x-11) degrees and angle U is (4x+9) degrees, find the value of x.
Given:
Consider angle S is congruent to angle U.
The angle S is (5x-11) degrees and angle U is (4x+9) degrees,
To find:
The value of x.
Solution:
Since it is given that angle S is congruent to angle U, therefore the measure of theses two angles are equal because measure of congruent angles are equal.
[tex]m\angle S=m\angle U[/tex]
Put the given values.
[tex]5x-11=4x+9[/tex]
Subtract 4x from both sides.
[tex]5x-4x-11=9[/tex]
Add 11 on both sides.
[tex]x=9+11[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20.
The coordinates of point T are (0, 5) . The midpoint of overline ST is (1, - 2) . Find the coordinates of point S
Plz hurry if u can!!!
The midpoint of a line segment is the point equidistant to the endpoints of the line. The coordinate of S is (2,-9)
Given that:
[tex]T(x_1,y_1) = (0,5)[/tex]
[tex]M = (1,-2)[/tex] --- the midpoint of ST
[tex]S = (x_2,y_2)[/tex]
To calculate the coordinates of S, we use the following midpoint formula:
[tex]M = 0.5 \times (x_1 + x_2,y_1+y_2)[/tex]
So, we have:
[tex](1,-2) = 0.5 \times (0 +x_2,5 + y_2)[/tex]
Divide both sides by 0.5
[tex](2,-4) = (0 +x_2,5 + y_2)[/tex]
[tex](2,-4) = (x_2,5 + y_2)[/tex]
Compare both sides
[tex]x_2 = 2[/tex]
[tex]5 + y_2 = -4[/tex]
Collect like terms
[tex]y_2 = -4-5[/tex]
[tex]y_2 = -9[/tex]
Hence, the coordinates of S is:
[tex]S = (2,-9)[/tex]

A taxi charges a flat fee of $5.00 plus $3.25 per mile.
How much will it cost to travel 8.7 miles? Round your answer to the nearest cent.
Answer:
$33.28
Step-by-step explanation:
8.7 times 3.25 is 28.275
28.275 + 5 = 33.275
33.275 rounded to the nearest coin is 33.28
Answer:
$33.28
Step-by-step explanation:
So, we would multiply $3.25 by 8.7 miles.
$3.25 · 8.7 = $28.28
Then we would add on the additional $5.00
$28.28 + $5.00 = $33.28

One half of a is 14 more than 2 times the number.find the number?
Answer:
Let n represent the number
One half of a number= ½ n
Now, the equation will be=
½ n =14+2n
On multiplying both sides by 2, we obtain
n=2(14+2n)
n=28+4n
On subtracting 4n from both the sides,we obtain
n-4n=28
-3n=28
On dividing both sides by -3, we obtain
n= -28/3

Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
For this, we shall use the slope formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is [tex]\frac{rise}{run}[/tex]
Assuming this is a line, all we do is pick two consecutive points and plug them in. For example, let's take the first two points. (1, -4) and (7, 5) as they are the easiest to work with.
Let's plug in these two values:
[tex]\frac{5 - (-4)}{7 - 1}[/tex]
Simplified we get:
[tex]\frac{9}{6}[/tex]
We are now able to factor 3 out of the numerator and denominator:
[tex]\frac{3}{2}[/tex]
Thus resulting in the slope.

Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?
Answer:
Rebecca's overtime rate is $20.25 per hour
Step-by-step explanation:
Rebecca is paid $13.50 per hour as her regular wage.
Her boss pays her that amount and a half for overtime work.
Half of her regular pay rate is 13.50/2= $6.75
Thus, her overtime rate is:
$13.50 + $6.75 = $20.25
Rebecca's overtime rate is $20.25 per hour
