The rate of change is the starting height, and the initial value is the
number of inches grown per month.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept
Given,
A sunflower is 13 inches tall and grows 41 inches each month.
The sunflower's height is a linear function of time.
A linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
y=13+41x.
Here x represents the number of months
13 is the initial height of the sunflower.
In the given options, The rate of change is the starting height, and the initial value is the number of inches grown per month is the statement best describes the rate of change and initial value of this function
Hence, The rate of change is the starting height, and the initial value is the number of inches grown per month

Decide where the first digit of the quotient should be placed without performing division The first digit of the quotient for 2,370 = 24 should be in the Choose... ones tens hundreds thousands
Answer:
tens place
Step-by-step explanation:
24 can't be into the thousands place or the hundreds place. hope this helps
Answer
hundredths place
Step-by-step explanation:
When performing long division, the first digit of the quotient appears over the least significant digit of the first portion of the dividend that is greater than or equal to the divisor.
Here, when performing long division we compare ...
64 vs 1 . . . no quotient digit
64 vs 15 . . . no quotient digit
64 vs 159 . . . the first quotient digit appears with the same place value as the 9 in 1.59. That is, the first quotient digit will be 0.02, 2 in the hundredths place.

Match the unknown entries in the two matrices with their correct values
Answers:
v = 54y = 0u = 6w = -48x = -1===================================================
Explanation:
The left hand side is
[tex]-6\begin{bmatrix}3 & -1 & 3\\8 & x & -9\\4 & -1 & y\end{bmatrix}[/tex]
That -6 outside the matrix is multiplied with each item inside the matrix. This is known as scalar matrix multiplication. Effectively, it's very similar to the idea of the distributive property.
So for the first row, we have the three columns of: -6*3 = -18 and -6*(-1) = 6 and -6*3 = -18
The other two rows are handled the same way. This is what should result:
[tex]-6\begin{bmatrix}3 & -1 & 3\\8 & x & -9\\4 & -1 & y\end{bmatrix}= \begin{bmatrix}-18 & 6 & -18\\-48 & -6x & 54\\-24 & 6 & -6y\end{bmatrix}[/tex]
From here, you'll then match up the terms in the given right hand side matrix. The top row has the variable 'u' in the middle, which matches with the '6' in the middle of the top row shown. Therefore, u = 6.
-----------------------------
Now to the second row.
The -48 in the first spot pairs up with the w in the other matrix. So we can see that w = -48. Similarly, we have v = 54.
Also, we have -6x in the middle which matches with the 6 in the same corresponding spot. Solving -6x = 6 leads to x = -1.
-----------------------------
Finally, the third row.
There's only one variable here and that's the variable y in the bottom right corner. It pairs up with 0 in the same corresponding spot for the right hand side matrix. Therefore, y = 0.

49. [tex]x = \dfrac{1}{a}[/tex] and [tex]y = 3[/tex]
50. [tex]x = \dfrac{1}{2a}[/tex] and [tex]y = \dfrac{1}{b}[/tex]
Step-by-step explanation:
We are going to solve these systems of equations using the elimination method.
49. Given:
[tex]5ax + 4y = 17[/tex] (1)
[tex]\:\:ax + 7y = 22[/tex] (2)
Multiply Eqn(1) by 7 and multiply Eqn(2) by -4 to get
[tex]\:\:35ax + 28y = 119[/tex]
[tex]-4ax - 28y = -88[/tex]
Adding the two equations above, we get
[tex]31ax = 31 \Rightarrow x = \dfrac{1}{a}[/tex]
Substituting this value for a into Eqn(2), we get
[tex]y = 3[/tex]
50. Given:
[tex]4ax + \:\:by = 3[/tex] (3)
[tex]6ax + 5by = 8[/tex] (4)
Multiplying Eqn(3) by -5, we get
[tex]-20ax - 5by = -15[/tex]
[tex]\:\:\:\:\:\:6ax + 5by = \:\:8[/tex]
Adding the two equations above, we get
[tex]-14ax = -7 \Rightarrow x = \dfrac{1}{2a}[/tex]
Plugging in the value of x into Eqn(3), we get the value for y as
[tex]4a(\frac{1}{2a}) + by = 3[/tex]
or
[tex]2 + by = 3 \Rightarrow y = \dfrac{1}{b}[/tex]
Determine whether the quadratic function shown below has a minimum or maximum, then determine the minimum or maximum value of the function.
f(x)=2(x−8) ^2−3
Answer:
It's a minimum, at (8, -3)
Step-by-step explanation:
Option 1: you unwrap the square , add like terms, and then recognize it's a parabola and find the coordinates of the vertex.
Or look at it as -3 + something ^2. It means you are adding something positive to -3, so the sum is greater or equal to -3, that is the definition of a minimum. At that point you find the minimum by setting that something equal to 0 (which gives you x = 8) and the value is -3 + 0 = -3
