Answer:
1) 5/7
2) (21, 5)
Step-by-step explanation:
1) The slope of the line passing through the points (7, 5) and (21, 15) is
[tex]\frac{15-5}{21-7} =\frac{10}{14}=\frac{5}{7}[/tex]
because slope is (difference of y)/(difference of x)
the first option is correct
2) 1/3 of 5/7 is 5/21.
The line will be in the form of
y = 5/21 x + b where b is the y-intercept.
Find the complete equation by plugging in (0,0) since it passes thorugh the origin.
0 = 5/21 (0) +b
0=0+b
b=0
The equation: y=5/21 x
let's check each option by plugging in.
y= 5/21 (3)= 5/7
y is not 5 but 5/7
y= 5/21 (3)= 5/7
y is not 7 but 5/7
y= 5/21 (21) = 5
y is 5, which matches with the answer choice!!!
y= 5/21 (21) = 5
y is 5, not 7.
The third option is correct

The product of two consecutive integers is 420. Which quadratic equation can be used to find x, the lesser number? x2 + 1 = 420 x2 + 2 = 420 x2 + x = 420 x2 + 2x = 420
Answer:Answer:
The answer is x^2 + x =420
Step-by-step explanation:
It is given that
The product of two consecutive integers is 420
Le x be the first number, then
second number is the next consecutive number of x which is (x +1)
The product of these numbers can be written as
x (x + 1) which is equal to 420
x (x + 1) = 420
x^2 + x = 420
So the quadratic equation is
x^2 + x = 420

1. A multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. What is
the resistance of the starter motor?
А
Given: Current (1)
Voltage (V)
Required: Resistance (9)
V
Formula:
R= voltage
curent
Solution:
V - IR
Answer:
Resistance -
92, the resistance of the electric motor.
Answer: 0.20 Ω
Step-by-step explanation:
From the question, we are informed that a multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. The resistance of the starter motor will be calculated thus:
Current (I) = 60.0A
Voltage (V) = 12V
Resistance = Unknown
Since Voltage = Current × Resistance
Therefore, Resistance = Voltage / Current
= 12/60
= 0.20 Ω
The resistance of the motor is 0.20 Ω
The resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms
Based on the given question, for us to get the resistance of the starter motor, we will need to use Ohm's law.
According to the law, the current I passing through a conductor at constant temperature is directly proportional to the voltage "V". Mathematically;
V = IR
V is the voltage = 12V
I is the current = 60.0A
R is the resistance
Substitute the given parameters into the formula as shown:
12 = 60 R
R = 12/60
R = 1/5
R = 0/2
Hence the resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms

Step-by-step explanation:
If you get 2 imaginary answers when using the quadratic formula, how does this relate to how many times (0, 1 or 2) a quadratic graph touches/crosses the x-axis?
Answer:Roots of a number indicates value where function will be zero. If an equation let's say
y = f(x) = x^2 -3x + 2 has two roots x = 1 and x =2 . Now if you will draw the graph, line will cross x-axis at 1 and 2 indicating y will become zero at 1 and 2. But if any equation has imaginary roots implies y will be never be zero for any real value of x and as we do not show imaginary number on a Cartesian plane we cannot make y =0 hence graph will never touch x-axis.

Find x. My teacher gave me what x equals but I don’t know the step-by-step explanations. x=6
Step-by-step explanation:
The triangle is isosceles, so the base angles are the same.
All three angles add up to 180°.
(6x + 4) + (6x + 4) + (18x − 8) = 180
30x = 180
x = 6
Answer:x=6
Step-by-step explanation:since those two sides shown are the same length, the missing angle is also 6x+4. the angles on a triangle always will equal 180. so you set the problem up as 6x+4+6x+4+18x-8=180. when you combine like terms it is then 30x=180. x=6

16x-4x +48x +88xStep-by-step explanation:
Like terms are ones with the same variable (or set of variables). Here, any x-terms are "like" terms. They are combined by adding their coefficients.
4x +4x +4x +4x = x(4+4+4+4) = 16x
-7x +4 +3x = x(-7+3) +4 = -4x +4
3x +5x +8 = x(3+5) +8 = 8x +8
4x +4x = x(4+4) = 8x

12) If tan A=5/12 . find the value of (sin A + COS A) sec A.
Answer:
(sin(A) + cos(A)).sec(A) = 17/12
Step-by-step explanation:
tan(A) = 5/12
sin(A) = 5/13
cos(A) = 12/13
sec(A) = 1/(cos(A)) = 13/12
(sin(A) + cos(A)).sec(A) = (5/13 + 12/13).13/12
= 17/13.13/12
= 17/12
