Answer:
slope = -3
x-intercept = (4/3,0) = (1.33,0)
y-intercept = (0,4)
f(-1) = 7
Step-by-step explanation:
Take 2 known points
i.e (0,4) and (1,1) from the graph
slope = (1-4)/(1-0) = -3
now we have
linear equation
y = mx+c
we have (0,4)
4 = -3 * 0 + C
C =4
so the equation of line is
y = -3x + 4
now
f(-1) = -3 * -1 +4 = 3+4 =7
for x intercept, put y = 0
o = -3x + 4
x = -4/-3 = 4/3
for y intercept, x = 0
y = -3 * 0 + 4 = 0+4 = 4
Shown here is a mathematical step taken when solving an equation. Identify the mathematical reason or property used to simplify from the first step to the second step. B+7=15. B=8
Answer:
Subtration property of Equality
Step-by-step explanation:
B + 7 = 15
- 7 - 7
B = 8
The equation B + 7 = 15 becomes B = 8 by subtraction property of equality thus option (C) is correct.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use b.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given equation,
B + 7 = 15
Subtract 7 on both sides,
B + 7 - 7 = 15 - 7
B = 8
Hence "The equation B + 7 = 15 becomes B = 8 by subtraction property of equality".

How long will it take for the concentration to reach 0.0500 M?
This question is incomplete, the complete question is;
A general reaction written as A + 2B → C + 2D is studied and yields the following rate law: ∆A/∆t = k A².
The initial concentration is 1.000 M and t½=20.00 s.
How long will it take for the concentration to reach 0.0500 M
Answer:
it will take 380 seconds for the concentration to reach 0.0500 M
Step-by-step explanation:
Given that;
A + 2B → C + 2D
initial concentration A₀ = 1 M
half life t1/2 = 20sec
concentration after t time [A_t] = 0.0500 M
∆A/∆t = k A²
This is a second order chemical kinetics
for this order; t1/2 = 1 / [A]₀K
A₀ is initial concentration, K is rate constant, t1/2 is half life
so,
k = 1 / [A₀]t1/2
we substitute
K = 1 / 1.000 × 20
K = 0.05 mol⁻¹L/sec
for second reaction order
1/[A_t] = kt + 1/[A₀]
kt = 1/[A_t] - 1/[A₀]
we substitute
kt = 1/0.0500 - 1/1.000
kt = 20 - 1
kt = 19
substitute the value of k
0.05 × t = 19
t = 19 / 0.05
t = 380 sec
Therefore it will take 380 seconds for the concentration to reach 0.0500 M

Find the perimeter of the figure to the nearest hundredth, if a =9 and b=2.
Answer:
e. 23.14 m
Step-by-step explanation:
Perimeter of the figure = ½(perimeter of a circle) + 2(a) + b
= ½(πd) + 2(a) + b
Where,
d = 2 m
a = 9 m
b = 2 m
Plug in the values into the equation
Perimeter of the figure = ½(π*2) + 2(9) + 2
= π + 20
= 23.14 m (nearest hundredth)
A washer and dryer cost $1011 combined the washer cost $61 more than the dryer what is the cost of the dryer
Answer:
$475
Step-by-step explanation:
First, we need to subtract 61 from 1011 which given us 950. Then, we divide 950 by 2 to give us the cost of the dryer :)
950 ÷ 2 = 475
This means the cost of the washer is $536 (not relevant to the answer, but at least now you know :) )

Given the following table, find the equation that matches it.
Answer:
The equation that matches the table is y = -5x + 7 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given table
→ Choose any two points from the table
∵ Points (0, 7) and (1, 2) are in the table
∴ x1 = 0 and y1 = 7
∴ x2 = 1 and y2 = 2
→ Substitute them in the rule of the slope above
∵ m = [tex]\frac{2-7}{1-0}=\frac{-5}{1}[/tex]
∴ m = -5
→ Substitute it in the form of the equation above
∵ y = -5x + b
∵ b is the value of y at x = 0
∵ At x = 0, y = 7
∴ b = 7
∴ y = -5x + 7
∴ The equation that matches the table is y = -5x + 7

a Black Friday sale and she bought a TV that was originally $200. The TV
was marked down 25%. How much did Sally pay after it was marked down?
(1 point)
Answer:
150$
Step-by-step explanation:
In order to find the answer to this question you must find twenty-five percent of two-hundred.
50% of 100 = 50
100% of 100 = 100
100% of 200 = 200
50% of 200 = 100
25% of 200 = 150
= 150$
