Coordinates (x, y)Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (-10, 6) → x₁ = -10, y₁ = 6
Point (-15, 7) → x₁ = -15, y₁ = 7
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [Slope Formula]: [tex]\displaystyle m=\frac{7-6}{-15+10}[/tex][Fraction] Subtract/Add: [tex]\displaystyle m=\frac{1}{-5}[/tex][Fraction] Convert: [tex]\displaystyle m=-0.2[/tex]We will be using the above formula. The answer will be a bit rough.
Okay. So our two points are (-10, 6) and (-15, 7). The number first in the brackets is always the 'x' variable while the second number in the bracket is always the 'y' variable. I will be using ² instead of the bottom 2 (As shown in the formula).
x = -10 x² = -15
y = 6 y² = 7
7 - 6
m = ———
- 15 - (-10) = -15 + 10
1
m = ——— OR - 0.2

How do the 6s in 0.96 and 93.601 compare?
The value of the 6 in 0.96 is 100 times the value of the 6 in 93.601.
The value of the 6 in 0.96 is 10 times the value of the 6 in 93.601.
The value of the 6 in 0.96 is 110 the value of the 6 in 93.601.
The value of the 6 in 0.96 is 1100 the value of the 6 in 93.601.
Answer:The value of the 6 in 0.96 is 1/10 the value of the 6 in 93.601. This is because the 6 in 0.9 compared to the 6 in 93.601 which is in the tenths place.
Step-by-step explanation:The value of the 6 in 0.96 is 1/10 the value of the 6 in 93.601. This is because the 6 in 0.96 is in the hundredths place, compared to the 6 in 93.601 which is in the tenths place.
Answer:
The value of the 6 in 0.96 is 110 the value of the 6 in 93.601

A ladder is leaning against a vertical wall. The distance from the top of
the ladder to the base of the wall is 23 feet. The distance from the base
of the wall to the bottom of the ladder is 5 feet. What is the length of the
ladder (nearest tenth)?
Answer:
23.5(to the nearest tenth)
Step-by-step explanation:
pythagoras theorem states
c^2= a^2+ b^2
a= 23
b=5
c^2= 529+25
c^2= 554
c= square root of 554
c = 23.5 (approximately)

Use I = PRT to solve.
(time is in years)
1 = $312.50
R = 25%
T = 0.25 years
Find P.
Please help :)) for 35 points !
Answer:
Step-by-step explanation:
I = PRT
PRT = I
P = I/RT
P = 312.50/(.25)(.25)
P = 312.5/.0625
P= $5000
Principal for the given interest, rate of interest and time period is $5000.
Given that, I = $312.50, R = 25% and T = 0.25 years.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Now, SI=(P × R × T)/100
312.50= (P × 25 × 0.25)/100
⇒ P × 25 × 0.25 = 31250
⇒ P = 31250/6.25
⇒ P = $5000
Therefore, principal for the given interest, rate of interest and time period is $5000.

Write an equation of the parabola in intercept form that passes through (-2, 0.05) with x-intercepts of -7 and -3
Important things you need to know:
1. x intercept = solution of the equation
2. parabola = the highest power is x²
3. "passes through" is important because you have the y intercept (it is the c in ax² + bx + c = 0)
The intercept form is y = a(x-r)(x-s), where r and s are the x intercepts (solutions) of the graph
Substitite the numbers and values you know:
y = a(x-r)(x-s)
0.05 = a(-2-(-7)) × (-2-(-3))
Then you should find a.
Rewrite the equation in the form of y = a ( x+7 )( x+3 ) where the value of a is found.
Which values of a and b make the following equation true?

Answer:
4/3
Step-by-step explanation:
Line equations are of the format:
y = m*x + b
((m is slope; b is y-intercept))
So this line has a slope of 4/3 and a y-intercept of -2/3.

Si para introducirun producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200
Complete question :
si para introducir un producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200 ¿que porcentaje se cobra por impuesto?
Responder:
18,75%
Explicación paso a paso:
Dado que:
Monto cobrado por impuestos = $ 225
Costo del producto sujeto a impuestos = $ 1200
El porcentaje del precio de costo del producto que se grava:
Sea porcentaje = x%
x% * precio de coste = importe de impuestos
0.01x * $ 1200 = $ 225
12x = 225
x = 225/12
x = 18,75
Por tanto, porcentaje de impuesto = 18,75%
