Answer:
y - 3 = 2(x+1)Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)

Solve for s
2s = 6t+8w
Answer:
s = 3t + 4w
Step-by-step explanation:
2s = 6t + 8w
s = 3t + 4w
Answer:
s = 3t+4w
Step-by-step explanation:
2s = 6t+8w
s = (6t+8w) ÷ 2
(6t÷2=3t, 8w÷2=4w)
s = 3t + 4w
Can someone please help me figure this out (trig) (pre calc)
Answer:
1. x = 1.5 rpm
2. x ≈ 0.8182 mi/hr
3. x = 6.6 feet
4. x = 4224 rpm
5. x = 390 rpm
Step-by-step explanation:
The relationship between angular speed and linear speed is given as follows;
Angular speed, ω = Linear speed, v/(Radius, r)
Therefore, we have;
1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm
2. When, ω = 4 rpm, and r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr
3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet
4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm
5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

Answer:
First choice
Step-by-step explanation:
To solve the system of equations below, Lisa isolated the variable y in the first
equation and then substituted it into the second equation. What was the
resulting equation?
[2y = 6x
[x² + y = 28
OA. x²-3x = 28
B. x² + 3x = 28
OC. 9x² + 3x = 28
OD. 4x² = 28
C
The resulting equation after substitution in system of equations :2y = 6x , x² + y = 28 will be option B : x^2 + 3x = 28
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
The given system of equation are :
2y = 6x.....(1)
[x² + y = 28.........(2)
also, Lisa isolated the variable y in the first equation and then substituted it into the second equation that is :
she substitute y = 3x in second equation :
x^2 + y =28
x^2 + 3x = 28
Therefore, the resulting equation after substitution will be option B : x^2 + 3x = 28

Answer:
f(x) = -2|x| +1
Step-by-step explanation:
The vertical translation is 1 unit upward, and there is no horizontal translation. So, the function will be something of the form ...
f(x) = a|x| +1
The slopes of the lines have a rise/run with a magnitude of 2/1, so the value of 'a' will have a magnitude of 2. The appropriate choice is ...

Answer:
y = 65x + 250
Step-by-step explanation:
Let the linear equation representing the relation between total pay and number of computers sold be,
y = mx + c
Here, m = commission on every computer sold = slope of the linear function
c = weekly salary
y = total pay
x = number of computer sold each week
Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table attached,
Slope of the line passing through (4, 510) and (6, 640),
m = [tex]\frac{640-510}{6-4}[/tex]
= 65
Equation of the line will be,
y = 65x + c
Since, this line passes through (4, 510),
510 = 65(4) + c
c = 510 - 260
c = 250
Therefore, equation of the line will be,
y = 65x + 250
Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
The average rate of change on the given interval is 9/70
Step-by-step explanation:
Here, we are to find the average rate of change of the function on the given interval
We proceed as follows;
on an interval [a,b] , we can find the average rate of change using the formula;
f(b) - f(a)/b-a
From the question;
a = 0
b = 3
f(0) = -3/5
f(3) = -3/14
Substituting the values, we have;
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70

x+2/2x-6=3/8 solve using multiplication property of equality
The solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to solve using multiplication property of equality?The equation is given as
x+2/2x-6=3/8
Apply the multiplication property of equality.
So, we have
8(x + 2) = 3(x - 6)
Open the brackets
8x + 16 = 3x - 18
Collect the like terms
5x = -34
Divide both sides by 5
x = -34/5
Hence, the solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5
