Answer:
Step-by-step explanation:
The parenthesis can cancel because the lack of anything you can do in them, so that will leave you with 7m + 3 + 7m + 6
Next step is to add like numbers, you should start by adding 7m + 7m, which would be 14m.
Next would be to add 3 + 6, which is nine.
To end this equation, simply put 14m + 9
There is no one-number answer because we do not know what m is. So the equation 14m + 9 is the final answer.
Find the slope of the line passing through the points (-7, 8) and (5, -7)
Answer:
5/4
Step-by-step explanation:
the equation for slope is:
y² - y¹
m= x² - x¹ , except the ones and twos are at the bottom by the x. if you plug into the equation you get:
-7 - 8
m= 5 - (-7) = 5 + 7. that equation equals
-15. 5
m = 12 = 4
Slope of the line passing through the points (-7, 8) and (5, -7) is [tex]\frac{-5}{4}[/tex]
What is slope of the line?The slope of a straight line between two points says ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex])can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter 'm'.
As we know that slope of line (m) passing through ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is given as
m = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
As the line passing through the points (-7, 8) and (5, -7)
m = [tex]\frac{-7-8}{5-(-7)}[/tex]
m = [tex]\frac{-15}{12}[/tex]
m = [tex]\frac{-5}{4}[/tex]
Hence, slope of the line passing through the points (-7, 8) and (5, -7) is [tex]\frac{-5}{4}[/tex]

-△DEF ~ △GHI
-△GHI ~ △ABC
-△GHI ~ △JKL
-△JKL ~ △ABC
Answer:
Umm.. I think the second one in the first two pairs and the last one on the bottom
Step-by-step explanation:
I don't know for sure tho.. I'm sorry if it's wrong
The pair of triangles that are similar are △DEF ~ △GHI and △JKL ~ △ABC
Given:
△ABC
length = 20
Base = 14
length / base = 20/14
= 10/7
△DEF
length = 10
Base = 8
length / base = 10/8
= 5/4
△GHI
length = 12
Base = 15
length / base = 15/12
= 5/4
△JKL
length = 10
Base = 7

y-b=m(x-a)
y--8=16/15(x--8)
y+8=16/15(x+8)

A circular pizza with diameter of 10 inches. The pizza is in a square box with side lengths of 14 inches. In square inches, how much of the box is empty?
Answer:
117.45 in²
Step-by-step explanation:
Given that:
Diameter of circular pizza = 10 inches
Length of square box = 14 inches
Area of a square = a²
Where a = side length
Area of square = 14² = 196 in²
Area of circle :
pi * r²
Pi = 3.142 ; r = d/2 = 10/2 = 5 inches
Area of circle = 3.142 * 5² = 78.55 in²
Amount of the box which is empty :
196 in² - 78.55 in² = 117.45 in²

*ratios and proportions*
Answer:
So, first you need to set up a proportion and cross multiply. This allows you to get an equation which you can solve for x.
Step-by-step explanation:
[tex]\frac{4}{5}[/tex] × [tex]\frac{17}{x}[/tex]
Cross multiply to get 4x = 85
Next, isolate the x variable by dividing the 4 on both sides. This leaves you with x = 21.25.
Answer: x = 21.25

Find the last angle measurement. Note that the total angle measurement of the interior angles of a triangle = 180°.
It is given that two of them are 50 & 60. Find the last measurement:
180 - (50 + 60) = 180 - 110 = 70.
Note that to find the sides without proper measurements, the angles OPPOSITE of the sides determine the value. The greater the angle's value, the greater the opposite side's measurement value.
In this case, side a will be the least as it is opposite of 50°, side c will be next as it is opposite of 60°, and side b will be the greatest as it is opposite of 70°.
