Jon rode his bike at a constant speed. He rode 1 mile in 4 minutes.
Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
Answer:
d/t=r or distance divided by time equals rate
Step-by-step explanation:
We can implement that formula to Jon’s problem. In his problem it will be 1/4 which equals one-fourth. So Jon’s rate is 1/4 mpminute.

What Plus -11 gives me 15
Answer:
i think it's postive 26
Answer:
26.
Step-by-step explanation:
If you want to "cancel" out the -11, you add 11 to make it go to 0. Then, you add 15 to 11, because you have 11 over from when you moved to -11 to 0. 15 plus 11 is 26.

what is the slop of the line that contains the points (-2,7) and (2,3) ?
Answer:
The answer would be -1
Step-by-step explanation:
Slope = ∆y/∆x
= (y2- y1 )/(x2- x1)
y2=3
y1= 7
x2=2
x1= -2
= (3-7)/(2--2)
= -4/(2+2)
= -4/4
= -1

Which statement describes the graph of this polynomial function?
f(x)= x4 + x3 - 2x2
Answer:
NOT c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The graph crosses the x-axis at x = 2 and x = –1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = 2 and x = –1 and crosses the x-axis at x = 0.
The graph touches the x-axis at x = –2 and x = 1 and crosses the x-axis at x = 0.

Select the ordered pair that is a solution of the system of linear equations.
y = 4x-7
y=-x+3
Answer:
(−4/5,19/5)
Step-by-step explanation:
The solution of the system of linear equations will be;
⇒ x = 2
⇒ y = 1
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of linear equations is,
⇒ y = 4x - 7
⇒ y = -x + 3
Now,
Since, The system of linear equations is,
⇒ y = 4x - 7 ..(i)
⇒ y = -x + 3 ..(ii)
Equate (i) and (ii) we get;
⇒ 4x - 7 = - x + 3
⇒ 4x + x = 7+ 3
⇒ 5x = 10
⇒ x = 2
And, We get;
⇒ y = 4x - 7
⇒ y = 4 × 2 - 7
⇒ y = 8 - 7
⇒ y = 1
Thus, The solution of the system of linear equations will be;
⇒ x = 2
⇒ y = 1
