y = -x-4
C.
y=x+4
by=-x+4
d. y = x-4
Answer:
y = -x + 4
Step-by-step explanation:
Mathematically, the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from the plot, the y intercept is 4
So we have;
y = mx + 4
To get the value of m, we substitute the coordinates of any point and solve for m
we select the point; (4,0)
so;
0 = m(4) + 4
4m = 0-4
4m = -4
m = -1
so the equation of the line is;
y = -x + 4

Ronald has 5 2/3 cups of a smoothie he then drank 1 3/4 cups of the smoothie how many cups were left
Answer:
4 1/6 cups of the smoothie were left.
Step-by-step explanation:
The LCD here is (3)(4) = 12.
Thus, 5 2/3 cups equals 5 8/12 and 1 3/4 cups equals 1 6/12 cups.
Subtract 1 6/12 cups from the original 5 8/12 cups. We get:
5 8/12
-1 6/12
-----------
4 2/12, or 4 1/6.
4 1/6 cups of the smoothie were left.

Step-by-step explanation:
Two trains are 1.5 miles apart, train a is traveling at 3/4 the speed of train b if they meet in 4 minutes how fast is each train going
Answer:
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.
Step-by-step explanation:
Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have the following kinematic equations:
Train A
[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)
Train B
[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)
If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:
[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]
[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]
[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]
[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]
[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]
Then, the speed of the train B is:
[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

in a class with 28 students, 18 learn English and 13 learn French. Some students learn both languages. What is the number of students learning both languages?
a) 2
b) 3
c) 4
d) 5
Answer:
3
Step-by-step explanation:
18 + 13 is 31.
31 is more than 28, and for the people who learn both languages(x), we can do 31-28 = x. 31-28 is 3, so the answer is B, or 3.

What happens to the value of the expression \dfrac{10}{d} d 10 start fraction, 10, divided by, d, end fraction as ddd increases from a small positive number to a large positive number?
Answer:
The quotient decreases
Step-by-step explanation:
Give the expression :
10 / d
What happens to the expression as d increases. from small positive to large positive ;
d in the expression is the denominator ;the value obtained by dividing the numerator by the denominator is the quotient.
Since the value of the numerator is constant ;
As the value of d increases, the quotient obtained becomes smaller `
For instance,
Let
d = 2;
10 /2 = 5
d = 3
10 / 3 = 3.333
d = 4
10 / 4 = 2.5
And the trend continues

10(x - 5) = -80 find the value of
Answer:
the value of x = -3
Step-by-step explanation:
10 (x-5) = -80
10x - 50 = -80
10x = -30
x = -3
CHECK:
10 ( -3 - 5) = -80
10 (-8) = -80
-80 = -80

Answer:
red = 28 apples
green = 13 apples
equations:
r + g = 41
r = g + 15
Step-by-step explanation:
r = number of red
g = number of green
r = g + 15 (the number of red apples is 15 more than the number of green apples)
r + g = 41
Substitute the firs equation into the second and solve for a numerical value of g
(g + 15) + g = 41
2g + 15 = 41
2g = 26
g = 13
Now solve for a numerical value of r
r = g + 15
r = 13 + 15
r = 28
checking the math:
r + g = 41
28 + 13 = 41

An experiment consists of rolling a number cube (dice). What is the probability of rolling a number GREATER THAN 4? Express your answer as a fraction in the simplest form.
Answer:
1/3
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur
Probability = Expected/Total outcome
Since the experiment requires rolling a dice
S = {1, 2, 3, 4, 5, 6}
Total outcome n(S) = 6
Number greater than 4 are;
Events E = {5,6}
Expected outcome n(E) = 2
Probability of rolling a number greater then 4 = 2/6
Probability of rolling a number greater then 4 = 1/3
Rob is on vacation in Paris, France. When Rob visited the Eiffel Tower today, he climbed 1,000 stairs in 25 minutes. Tomorrow, Rob will climb 280 stairs at Montmartre. If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow?
Answer:
7 minutes
Step-by-step explanation:
The computation of the number of minutes that climbs the stairs tomorrow is shown below:
Given that
He claimed 1000 stairs in 25 minutes
So for 280 stairs, he would take
= 280 × 25 minutes ÷ 1000 minutes
= 7000 ÷ 1000
= 7 minutes
hence, 7 minutes would be taken
The same is to be considered
Answer:
7 minutes

Find the distance between the two points in simplest radical form.
(-5,6) and (-3,-1)
Answer:
√53
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = -5
x2 = -3
y1 = 6
y2 = - 1
Solution
d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )
d = sqrt( ( -3 + 5)^2 + (-7)^2 )
d = sqrt( 2^2 + 49)
d = sqrt(4 + 49)
d = sqrt(53)
