The slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.
According to the given question.
We have a line AB containing the points A(4, 5) and B(9, 7).
Here, we have to find the slope of line AB.
As we know that, as we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).
Therefore, the slope of the line AB which passes through the points (4, 5) and B(9, 7)
= (7 - 5)/(9 - 4)
= 2/5
Hence, the slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.

find four consecutive multiples of 4 such that twice he sum of the least and greatest exceeds three times the least by 32.
According to the question, the four consecutive numbers can be written as :
First = [tex]x[/tex]; Second = [tex]x+2[/tex]; Third = [tex]x+4[/tex]; Fourth = [tex]x+6[/tex]
As per the question, the final expression is :
[tex]2((x+2)+(x+4)) = 3(x)+32[/tex]
[tex]4x+12 = 3x+32[/tex]
[tex]x = 20[/tex]
Therefore, the four values can be calculated by substituting the above value:
[tex]x=20; x+2=22; x+4=24; x+6=26[/tex]
The four consecutive numbers are: [tex]20,22,24,26[/tex]
Substitute the calculated values in the final expression, to check whether the answer is correct or not.
[tex]2(22+24) = 3(20)+32[/tex]
[tex]92=92[/tex]
Therefore, the calculated values are correct.

Some key features regarding the state legislatures are-
Every state (except Nebraska) has a bicameral legislature, which means the legislature is divided into two separate legislative chambers (or "houses"); Nebraska does have a unicameral, or one-chamber legislature. The smaller chamber is called the "Senate" in all bicameral legislatures and is commonly referred to as the "upper house." The smaller chamber generally, but not always, has the exclusive power to approve appointments made by the governor and to attempt articles of impeachment.To know more about the state legislatures, here

tolerance is an allowance made for imperfections in a manufactured object. the manufacturer of an oven specifies a temperature tolerance of ±15ºf. this means that the temperature inside the oven will be within 15ºf of the temperature to which it is set. write an absolute value equation to find the maximum and minimum temperatures inside the oven when the thermostat is set to 400ºf. let t represent the temperature inside the oven.
The highest temperature recorded was 415°F(maximum).
At its lowest, the temperature is 385°F(minimum).
How to to find the maximum and minimum temperatures ?The function of absolute value calculates the separation between a point and an origin.

an air conditioning system can circulate cubic feet of air per minute. how many cubic yards of air can it circulate per minute?
We know that ,
1 feet= 0.33 Yard
Given that .
An air conditioning circulate 1 cubic foot per minutes
So it circulates 0.33 Yards per minute .
an air conditioning system can circulate 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute13.32 yards per minute
Given that an air conditioning system can circulate 360 cubic feet of air per minute. This is the rate of cubic feet per minute. That is,
Rate = volume/time. Which is
360 = volume/ 1
Volume = 360 cubic feet
Convert cubic feet to cubic yard
1 cubic foot = 0.037 cubic yards
Multiply this by 360
Cubic yards = 360 × 0.037
Cubic yards = 13.32
Therefore, if 360 cubic feet can circulate air per minute, this is equal 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute to 13.32 cubic yards of air which can circulate air per minute

x= -136 and x = 80
x=-112 and x = 80
x= -80 and x = 80
Answer:
x = -136 and x = 80
Step-by-step explanation:
|(1/4)x +7| - 3 = 24
|(1/4)x + 7| = 27 (transpose 3 and it becomes positive)
now:
(1/4)x + 7 = 27 (first solution)
(1/4)x = 20
x/4 = 20
x = 20×4
x = 80
(1/4)x + 7 = -27 (second solution)
(1/4)x = -34
x/4 = -34
