Answer:
y = 2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, then
y = 2x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = 8 + c ⇒ c = 3 - 8 = - 5
y = 2x - 5 ← equation of line
7m - 17 = -24

Across what line of reflection was the angle reflected in the coordinate plane below?
Answer:
Let us revise the reflection
If point (x , y) reflected across the x-axis, then its image is (x , -y)
If point (x , y) reflected across the y-axis, then its image is (-x , y)
If point (x , y) reflected across the line y = x, then its image is (y , x)
If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point A (-5 , 8) is reflected across the line y = x
∵ If point (x , y) reflected across the line y = x , then its image is (y , x)
∵ x = -5 and y = 8
- Switch x and y
∴ The image of point A is A' = (8 , -5)
Mrs. Adele is buying a new tie from Macy's. It says
the tie costs $15.00 but there is a sign above it that
says 25% off. How much will the tie cost?
Answer:
$11.25
Step-by-step explanation:
You take the original cost and multiply it by 0.25 for 25%. You get 3.75. Then you subtract 3.75 from 15.00. The answer is $11.25

Points A, S, and R are ___.
Answer:
B
Step-by-step explanation:
I'm pretty sure it's B, (please let me know if I'm wrong.)
Colinear means to be on the same straight line, which they are.
Coplanar means to be in the same plane, which they appear to be as well.
So yeah I'm pretty sure it's B.

Step-by-step explanation:
Solve each system by substitution.
y=-4x-9 y=3x+19
Answer:
x=-4, y=7
Step-by-step explanation:
According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.
y = 3x + 19
-4x - 9 = 3x + 19
Add 9 to both sides
-4x = 3x + 28
Subtract 3x
-7x = 28
Divide by -7
x = -4
Plugging this into the equation, we have:
y = -4x - 9
y = -4(-4) - 9
y = 16 - 9
y = 7

Please do number 16 for me. (With work)
Answer:
m<5 = 75°
Step-by-step explanation:
16. Given:
m<1 = 75°; m<3 = 40°
Required:
m<5
Solution:
Since lines A and B are parallel, and m<1 corresponds to m<5, therefore,
m<1 = m<5 (corresponding angles are congruent)
m<1 = m<5 = 75°
m<5 = 75°

Answer:
64/109 ≈ 0.5872
Step-by-step explanation:
41 + 23 = 64 of the events have outcome E.
An additional 35 + 10 = 45 do not.
The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.
P(E) = 64/109 ≈ 0.5872

Raju covers a certain distance in 1 hour and sham covers the same distance in 2 hours , who travels in a higher speed?
Answer: Raju travels at a higher speed.
Step-by-step explanation:
[tex]Speed =\dfrac{Distance}{Time}[/tex]
Speed inversely proportional to time.
As time taken to cover a particular distance decreases the speed will increase.
Raju covers a certain distance in 1 hour.
Sham covers the same distance in 2 hours.
1< 2
Thus Raju travels at a higher speed.

Three fifths of the students in the cafeteria bought their lunch from the school. The rest brought their lunch from home. 27 of the students bought their lunch. Let t represent the total number of students in the cafeteria.
Answer:
45 students
Step-by-step explanation:
Three fifths of the students in the cafeteria bought their lunch from the school. The rest brought their lunch from home. 27 of the students bought their lunch. Let t represent the total number of students in the cafeteria.
We are to calculate the total number of students in the cafeteria.
Fraction of the students in the cafeteria that bought their lunch from the school = 3/5
Number of the students that bought their lunch = 27 students
The total number of students can be calculated as:
3/5 Of t = 27 students
3/5 × t = 27
Cross Multiply
3t/5 = 27
3t = 27 × 5
t = 27 × 5/3
t = 45 students
Therefore, the total number of students in the cafeteria = 45 students
