Q4: Write the equation in slope-intercept form of the line that is perpendicular to
the graph of each equation and passes through the given point. y = 2x - 3; (-5,3
Answer:
y= −1/2x+ 1/2
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula
y-y1=m(x-x1) to find the line perpendicular to y=2x−3.

The weight, y, in pounds, of puppies was tracked for the first 10 weeks after birth where t represents the number of weeks after birth. The linear model representing this relationship is ŷ = 2.3 + 5.73t. Collin wanted to predict the weight of a puppy at 14 weeks.
What is this an example of, and is this method a best practice for prediction? Explain your reasoning.
Answer:
This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks.
Step-by-step explanation:
thats just what it is
The solution is Option C )
This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks
What is Linear model?
A linear model is a model in which the terms are added, such as has been used so far in this section, rather than multiplied, divided, or given as a non-algebraic function. Linear modeling can predict the behavior of complex systems or analyze experimental, financial, and biological data.
Linear regression is a statistical method used to create a linear model. The model describes the relationship between a dependent variable y (also called the response) as a function of one or more independent variables Xi (called the predictors).
Given data ,
Weight of the puppies = y pounds
Number of weeks after birth = t
Linear model representing the relationship between weight of puppies and time after birth in weeks is y = 2.3 + 5.73t
This is a clear idea of Linear models because the data describe a continuous response variable as a function of one or more predictor variables.
Hence , this is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks

The formula for the area of a triangle is A =12bh, in which b represents the length of the base and h represents the height. If a triangle has an area of 232 mm 2 and the height is 16 mm, what is the measure of the base? The measure of the base is mm.
Answer:
Step-by-step explanation:
Write it out: A = 1/2(bh)
substitute values: 232 = 1/2(16b)
Simplify: 232 = 8b
Divide each side by 8: b = 29

Answer:
70°
Step-by-step explanation:
since two lengths are equal to 3.5 that’s means there’s are two equal angles (55° and 55°)
a triangle adds up to 180°
so to find x we set this up:
x +55 +55 = 180
x + 110 = 180
x = 70°

5b-b-1 > or equal too-11
Answer:
-2.5
Step-by-step explanation:
5b - b - 1 ≥ -11
4b - 1 ≥ -11
+1 +1
4b ≥ -10
4/4 -10/4
b ≥ -2.5
Answer:
b ≥ [tex]-\frac{5}{2}[/tex]
Step-by-step explanation:
The expression:
5b - b - 1 ≥ -11
Now to solve this problem, we must be aware of some rules of inequality.
When dividing or multiplying with a negative value, the sign of the inequality must change;
5b - b - 1 ≥ -11
4b - 1 ≥ -11
Add + 1 to both sides;
4b -1 + 1 ≥ -11 + 1
4b ≥ -10
Now divided both sides by 4;
[tex]\frac{4b}{4}[/tex] ≥ [tex]\frac{-10}{4}[/tex]
b ≥ [tex]-\frac{5}{2}[/tex]

Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5
amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.
Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".

Based on the graph, which inequality is correct for a number that is to the right of -3?
A number line is shown from negative 8 to 8 at increments of 1. A circle is shown at negative 3. The entire portion of the number line to the right of negative 3 is shaded.
a
4 > −3
b
−3 > 4
c
−2 < −3
d
−3 < −6
Answer:
The inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
Step-by-step explanation:
Given the inequality
[tex]-3\:>\:4[/tex]-3 can not be greater than 4, so [tex]-3\:>\:4[/tex] is also incorrect.
Given the inequality
[tex]-2\:<\:-3[/tex]-2 can not be lesser than -3, so [tex]-2\:<\:-3[/tex] is also incorrect.
Given the inequality
[tex]-3\:<\:-6[/tex]-3 can not be lesser than -6, so [tex]-3\:<\:-6[/tex] is also incorrect.
Given the inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
If hot and cold water taps are turned on altogether, a bath is filled in three minutes but if the cold tap was only half opened it would take one minute forty eight seconds longer. How long would the hot tap alone take to fill the bath?
9514 1404 393
Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.
