Variable p is 2 less than variable d. Variable p is also 1 more than variable d. Which pair of equations best models the relationship between p and d? (5 points)
a
p = d + 2
p = d − 1
b
p = d − 2
p = d + 1
c
d = 2p
d = 2p − 1
d
d = 2p
d = 2p + 1
Answer:
b)
p = d − 2
p = d + 1
Step-by-step explanation:
From the above question:
Interpreting the statement above to form algebraic expressions, we have:
Variable p is 2 less than variable d.
Less than means to subtract in this context
p = d - 2
Variable p is also 1 more than variable d
More than means to add in this context
p = d + 1
Therefore, the pair of equations tha best models the relationship between p and d is Option b :
p = d − 2
p = d + 1

4(x-11)=19 solve for x
Answer:
x = 63/4 or 15 3/4
Step-by-step explanation:
4(x-11)=19
Distribute
4x -44 = 19
Add 44 to each side
4x-44+44 = 19+44
4x = 63
Divide by 4
4x/4 = 63/4
x =15 3/4
Answer:
[tex]\huge\boxed{Answer\hookleftarrow}[/tex]
[tex]4(x - 11) = 19 \\ 4x - 44 = 19 \\ 4x = 19 + 44 \\ 4x = 63 \\ x = \frac{63}{4} \\ x = 15.75[/tex]
✐ The value of x is 63/4 (in fraction form) OR 15.75 (in decimal form).

Write an equation if the line that passes through (0,-2) and (2,2)
Answer:
[tex]y=2x-2[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (0,-2) and (2,2)
[tex]=\frac{2-(-2)}{2-0}\\=\frac{2+2}{2}\\=\frac{4}{2}\\=2[/tex]
Therefore, the slope of the line is 2. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=2x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=2x+b[/tex]
Plug in one of the given points and solve for b
[tex]2=2(2)+b\\2=4+b[/tex]
Subtract 4 from both sides to isolate b
[tex]2-4=4+b-4\\-2=b[/tex]
Therefore, the y-intercept of the line is -2. Plug this back into [tex]y=2x+b[/tex]
[tex]y=2x-2[/tex]

The probability that one shopper, selected at random prefers either Beverage A or Beverage C; P(A or C) = 12/25.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
We are looking for the probability that one shopper, selected at random prefers either Beverage A or Beverage C.
a. A probability distribution of the experiment.
The probability of selecting Beverage A is ;
P(A) = 15/50 = 0.3
The probability of selecting Beverage B is ;
P(B) = 12/50 = 0.24
The probability of selecting Beverage C is ;
P(C) = 9/50 = 0.18
The probability of selecting Beverage D is ;
P(D) = 6/50 = 0.12
The probability of selecting Beverage E is ;
P(E) = 8/50 = 0.16
b. The probability that one shopper, selected at random prefers either Beverage A or Beverage C.
P(A or C) = 15/50 + 9/50
P(A or C) = 24/50
Thus, P(A or C) = 12/25

Helppppppp meeeeeee I don’t understanddddd
Answer:
DF = 9.5
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
DE × DF = DC × DB
5(5 + x) = 5(5 + 4.5) ← divide both sides by 5
5 + x = 5 + 4.5
5 + x = 9.5 ( subtract 5 from both sides )
x = 4.5
Then
DF = DE + EF = 5 + 4.5 = 9.5

solve the inequality 14≥3x+2
Answer:
4 ≥ x
Step-by-step explanation:
14 ≥ 3x + 2
14 - 2 ≥ 3x
12 ≥ 3x
4 ≥ x
Solving the inequality 14 ≥ 3x+2 we get x ≥ 4.
What is inequality?In mathematics, an assertion of an order connection greater than, greater than, or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
Given:
14 ≥ 3x+2
Switch sides
3x+2 ≥ 14
Subtract 2 from both sides of the equation, we get
3x + 2 - 2 ≥ 14 - 2
Simplifying the above equation
3x ≥ 12
Divide both sides by 3, we get
3x/3 ≥ 12/3
x ≥ 4
Therefore, the value of x ≥ 4.

The first term of an AP is -7 and the ratio of the eight term to the third term is 7:1 calculate the common difference
Answer:
the common difference is 6.
Step-by-step explanation:
Given;
first term of an AP, a = -7
let the common difference = d
The third term is written as;
T₃ = a + 2d
The eight term is written as;
T₈ = a + 7d
The ratio of the eight term to third term = 7:1
[tex]\frac{T_8}{T_3} = \frac{7}{1} = \frac{a+ 7d}{a + 2d} \\\\7 = \frac{a+ 7d}{a + 2d}\\\\Recall, a = -7\\\\7 = \frac{-7+ 7d}{-7 + 2d}\\\\7(-7 + 2d) = -7+ 7d\\\\-49 + 14d = -7 + 7d\\\\14d -7d = -7 + 49\\\\7d = 42\\\\d = \frac{42}{7} \\\\d = 6[/tex]
Therefore, the common difference is 6.
