Step-by-step explanation:
The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables and c is the constant term. The other different forms to find and represent the equation of a line are slope-intercept form, point-slope form, two-point form, intercept form, and normal form.
The <em><u>correct answer</u></em> is:
pairs 1 and 3
Explanation:
Congruent figures are the same size and the same shape.
Pair 1 has two polygons that are the same size and same shape; they are congruent.
Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.
Pair 3 has two polygons that are the same size and same shape; they are congruent.
Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.
Answer:
Undefined
Step-by-step explanation:
(7 - 3 - 4) ÷ (-7 * (2+6))
(0) ÷ (-56)
Undefined because zero cannot be divided

Answer:
x = -4y/7 + 51/7
Step-by-step explanation:
First, you add all the numbers without variables and are on the same side.
7x - 4 + 4y + 8 = 55
Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.
4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8
4x + 4y = 51
Then you get the x by itself by doing the same thing you did with the last step by this time with 4y. Because this has a variable, you don't add it onto the 51, but add as a different number.
4x + 4y - 4y = 51 - 4y
4x = -4y + 51
Now to isolate the x, you divide 4x by 4.
4x/4 = -4y/7 + 51/7
x = -4y/7 + 51/7
Your answer is x = -4y/7 + 51/7
