Answer:

Step-by-step explanation:
evaluate the piecewise function
Answer:
f(-3)=-1
f(4)=7
f(-1)=-3
f(12) = -24
Step-by-step explanation:
Piecewise Functions
The piecewise functions define different pieces or subfunctions where the domain is divided into parts according to some conditions on the independent variable.
The pieces of the function are defined as shown below:
[tex]f(x)=\left\{\begin{matrix}-1 &x\le -2\\ 2x-1 &-2<x\le 4 \\ -3x+8 &x>4 \end{matrix}\right.[/tex]
Let's find the values of:
f(-3). Here the variable x is -3. We have to find the interval where x=-3 belongs. Since -3 ≤ -2:
f(-3)=-1
f(4). The variable x is 4 and it belongs to the second interval, thus
f(4)=2*4-1=7
f(4)=7
f(-1). x = -1. It belongs to the second interval, thus:
f(-1)=2*(-1)-1=-3
f(-1)=-3
f(12). x=12 belongs to the last interval since 12 > 4, thus:
f(12)= -3*12+8 = -36 + 8 = -24
f(12) = -24

What is the function rule?
Write the rule in function notation, using the slope-intercept form of a line.
Answer:
y = 2x - 5
Step-by-step explanation:
Okay. We have to get the slope first.
I'll be using points (3, 1) and (4, 3)
3 - 1
/
4 - 3
The slope is 2.
Now we can plug one of the points and the slope into point-slope form.
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
Answer:
y=2x-5
(3, 1) and (4, 3)
3 - 1
/
4 - 3
The slope is 2.
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
Graph the equation,show work
y - 4 = -3(x + 2)

Which expressions have a value between 5 and 6?
Select all that are correct.
- pi+2
- square root of 24
- square root of 38
- square root of 26
- pi/2
Answer:
the expression that have the value of 5 and 6 is 17
The expression [tex](\pi + 2)[/tex] and [tex]\sqrt{26}[/tex] lies between 5 and 6.
Square root:The value of [tex]\pi=3.14[/tex]
We have to find which value is lies between 5 and 6.
[tex]\pi +2=3.14+2=5.14\\\\\sqrt{24}=4.89\\ \\\sqrt{38} =6.16\\\\\sqrt{26}=5.09\\ \\\frac{\pi}{2}=3.14/2 =1.57[/tex]
From above calculation it is observed that expression [tex](\pi + 2)[/tex] and [tex]\sqrt{26}[/tex] lies between 5 and 6.

Kade measured the growth of a bean plant for 30 days. He plotted his
data and calculated the equation y = x + 3 to model the growth. Which
is the meaning of the y-intercept in this equation?
Answer:
y = x - 3
Step-by-step explanation:
Find the value of r so the line that passes through each pair of points has the given slope.
(5, 9), (r, –3), m = –4
The value of r is 8 for the points to have a slope of -4.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is also defined as the ratio of the rise and the run.
The slope is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the points are (5, 9) and (r, –3) and the slope is -4. The value of the unknown number will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
-4 = ( -3 - 9) / ( r - 5 )
-4r + 20 = -12
-4r = -32
r = 32 / 4
r = 8
Therefore, the value of r is 8 for the points to have a slope of -4.
