Both angles equal 47°
kramer3 years ago
5 0
These angles are equal to each other, so 
2x+35=7x+5
Clean this up and we get
30=5x
x=6
Check your answer
2(6) + 35 = 7 (6) + 5
12 + 35 = 42 + 5
47 = 47

Write an equation of the line that passes through a pair of points:<br> (-5, - 2), (4, 5)
attashe74 [19]

Answer (<u>assuming it can be written in slope-intercept form)</u>:

y = \frac{7}{9} x+\frac{17}{9}

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula, m = \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the given points into the formula and solve:

m = \frac{(5)-(-2)}{(4)-(-5)} \\m  = \frac{5+2}{4+5} \\m = \frac{7}{9}

So, the slope is \frac{7}{9}.

2) Now, use the point-slope formula y-y_1 = m (x-x_1) to write the equation of the line. Substitute m, x_1, and y_1 for real values.

Since m represents the slope, substitute \frac{7}{9} for it. Since x_1 and y_1 represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form (y = mx + b format) and find the following answer:

y-(5) = \frac{7}{9} (x-(4))\\y-5 = \frac{7}{9} (x-4)\\y -5=\frac{7}{9} x-\frac{28}{9}\\y = \frac{7}{9}  x-\frac{28}{9} +\frac{45}{9}\\y = \frac{7}{9} x+\frac{17}{9}

2) 13.2607 Round the above number to th
NARA [144]

Answer:

For number two, nearest whole number is 13. nearest hundredth is 13.26. number three I don't see anything.

Step-by-step explanation:

Explanation: When rounding, u look at the right number and if

greater than 4, round up which is add one

if right number is 4 or less we take nothing. also we change all other numbers behind the left number to 0. so round to a whole number it would be 13. 2 is smaller than 5. Nearest hundredth is the same thing. we look at the hundredth place which is 6. We look to the right. it's 0. less than 5 we round down. so it would be 13.2600. Or 13.26

number 3 I don't see anything so I can't help out
