Answer:
The car has an initial speed of 35 units and is slowing down by 4 units per second.
Step-by-step explanation:
The changing speed of a car is modeled by the function :
[tex]s(t)=-4t+35[/tex]
t is time in seconds
Initial speed means at t = 0
s(0) = 35 units
Here the change in speed is negative, it means that the car is slowing down by this rate.
So, the correct answer is : The car has an initial speed of 35 units and is slowing down by 4 units per second.

Answer:
1.) Ans -2 , 14
2.) Ans 2 1/5
3.) Ans y= mx+c
Step-by-step explanation:
first one you use Y = Mx +c
You see the Mx is a multiplication
and you input.
M * x = -5 x 2
M* x = -5 x -1
M* x = -5 x 3
M* x = -5 x -2
and note the answers will be less 4 as the equation states +4 is the y intercept and balances the equation.
So answers of the above in same order are;
-10
5
-15
10
we add 4
-6
9
-11
14
and see that 14 is the correct answer for y.
So the correct coordinates are -2, 14
Question 2) coordinates -1 k can equal = -5x+3
First we write as a division we know the gradient is -5
-we eliminate x
5x-1 / k+3
= 4x/k+3
M = -5
= 4x = -5(k+3)
= 4x = -5k +15
= 4x -15 =-5k
= -11 =-5k
= 11/-5 = k
k = 2 1/5
3) Ans The equation of a line is y=(input the number whatever times the x to make the number before you add)
y = m
3) Ans then you place x next to it
3) Ans then you place + 4 or whatever adds to the number.
So the equation of the line is what makes y its value through m the gradient being the number you times with x and the difference of that total to make y intercept.
Find y intercept and you have c of Mx+c
A curb is 4 inches high. The ramp from the sidewalk yo the street follows the same guidelines as other Ramos (no more than 4.8 degrees, so a 1:12 ratio of vertical to horizontal). What is the horizontal distance for a ramp with a 4 inch vertical distance?
Answer:
48 inches.Step-by-step explanation:
Givens
The height of a curb is 4 inches. So, the ramp has a height of 4 inches.The ratio between vertical and horizontal distance of the ramp is 1:12.Accoriding to the given ration, one unit of vertical distance is equivalent to 12 units of horizontal distance. So, the horizontal distance is
[tex]h=12(4 \ in)=48 \ in[/tex]
Therefore, the horizontal distance is 48 inches.
The horizontal distance for a ramp with a 4 inch vertical distance will be 48 inches.
Given,
The height of curb is 4 inches.
We have to calculate the horizontal distance for a ramp with a 4 inch vertical distance.
The ramp from the sidewalk of the street follows the same guidelines as other Ramos, no more than 4.8 degree.
Since The ratio of vertical to horizontal is 1:12, it means for a 1 inch vertical distance the horizontal distance is 12 inches.
So, for 4 inches of vertical distance the horizontal distance will be,
[tex]12\times4=48[/tex] inches.
Hence the required horizontal distance is 48 inches.

In the following quadratic equation identify the values of a, b, and c that you would use in the quadratic formula.
7x^2-3x+9=0
A. a=7 b=-3 c=9
B. a=9 b=7 c=-3
C. a=-7 b=3 c=-9
D. a=7 b=3 c=9
Answer:
A
Step-by-step explanation:
Let's first define what exactly the values of a, b, and c represent.
- a: this is the coefficient of the x^2 term
- b: this is the coefficient of the x term
- c: this is the constant term (no variable attached)
Our equation is: y = 7x^2 - 3x + 9.
The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.
Thus, the answer is A.
Answer:
The general quadratic equation is ax^2 + bx + c = 0
=> Here, we have: 7x^2 - 3x + 9 = 0 <=> 7x^2 + (-3)x + 9 = 0
=> a = 7, b = -3, c = 9
=> Option A is correct.

Examine the diagram. Triangle A B C. Angle A is (3 x minus 24 degrees) and angle B is x degrees. The exterior angle to angle C is 132 degrees. What equation can be used to find the value of x? What is the measure of ∠B? m∠B= °
Answer:
Setting up the equation you would have: 132 = x + (3x-24)
Now solve for x:
132 = x + (3x-24)
Simplify:
132 = 4x -24
Add 24 to both sides:
156 = 4x
Divide both sides by 4:
x = 156/4
x = 39
Step-by-step explanation:
The measure and equation that should be used is 39 and 132 = x + (3x-24)
Calculation of the equation used:Since angle B is x degrees. The exterior angle to angle C is 132 degrees.
Here the equation that should be used is shown below.
132 = x + (3x-24)
132 = 4x -24
156 = 4x
x = 39
