Write the following equations in slope intercept form
Equation 1: y-7x=6
Equation 2: y+7x=8
Answer:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Step-by-step explanation:
Isolate the y variables in both equations
Equation 1:
y - 7x = 6
y = 7x + 6
Equation 2:
y + 7x = 8
y = -7x + 8
So, the equations in slope intercept form are:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8

Answer:
When you have two parallel lines cut by a transversal, you get four acute angles and four obtuse angles . All the acute angles are congruent, all the obtuse angles are congruent, and each acute angle is supplementary to each obtuse angle.

X=_____
BC=10
Answer:
see explanation
Step-by-step explanation:
Since B is the midpoint of AC, then
AB = BC , substitute values
3x - 5 = x + 5 ( subtract x from both sides )
2x - 5 - 5 ( add 5 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus
BC = x + 5 = 5 + 5 = 10

Leah is writing an equivalent equation which solves for y. What should be her next step? 3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.
Given :
A linear equations :
3x+4y = 8 .
She have completed the following steps :
3x+4y = 8
3x+4y-3x = 8-3x
4y = 8 -3x
To Find :
The equivalent equation which solves for y.
Solution :
General equation of line or equation which solves for y is given by :
y = mx +c
So , our next step should be dividing both sides by 4 .
[tex]\dfrac{4y}{4}=\dfrac{8}{4}-\dfrac{3x}{4}\\\\y=2-\dfrac{3x}{4}[/tex]
Therefore , equation which solves for y is [tex]y=2-\dfrac{3x}{4}[/tex] .
Hence , this is the required solution .

−112.74 = 9.2p − 9.7
Answer:
p= -11.2
Step-by-step explanation:
-112.74 = 9.2p - 9.7
-103.04 = 9.2p (added 9.7 to both sides because its the inverse operation)
[tex]\frac{-103.04}{9.2}[/tex] = [tex]\frac{9.2p}{9.2}[/tex]
-11.2 = p

Answer:
The angle should be 74 degrees and they are supplementary
Step-by-step explanation:
It is 74 degrees because the two angles must add up to 180, so you can simply subtract 106 from 180 to get 74. The angles are supplementary because they add up to 180 degrees, while complementary angles only add up to 90 degrees

A:You can compare irrational numbers using rational approximation.
B:Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol.
C:You cannot compare the value of rational and irrational numbers.
D:The closer together the numbers being compared, the more decimal places you need to use.
The correct options are given below;-
1) You can compare irrational numbers using rational approximations
2) Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol.
3) The closer together the numbers being compared, the more decimal places you need to use
What is an irrational number?All real numbers that are not mathematically rational are referred to as irrational numbers. On the other hand, irrational numbers cannot be expressed as the ratio of two integers.
1) Due to the fact that both rational and irrational numbers are a component of the real numbers and, as a result, have distinct positions on the real number line, it is possible to compare the values of two irrational numbers based on their relative positions on the number line.
2) Square roots can be sorted in their order of magnitude and can also be compared by comparing and sorting the numbers under the radical sign because the values of square roots are directly proportional to the value under the radical symbol.
3) The difference between two numbers that are very close to one another will be little. Therefore, the value of the difference between the numbers must be increased by increasing the detail or the number of decimal places of the numbers in order to clearly highlight the differences between two near numbers.
Similarly, It is necessary to increase the level of detail or the number of decimal places when comparing two numbers that are extremely close to one another.

1. For the equation, x-7 = 24. can a value be substituted for x to make that a true
number sentence? How many values could be substituted for x and have a true
number sentence?
Answer:
The value 31 can be substituted for x. Only the value 31 can be substituted.
Step-by-step explanation:
So to solve a one step equation the goal is to isolate the variable. As you can tell from we are subtracting the 7. The opposite of addition is subtraction so we want to add the 7. -7 plus a positive 7 is 0 which cancels it out. Now we have x=24. However what you do to one side you need to do to the other. So we add 7 to the 24. 7+24 is 31. Therefore 31 can be substituted for x. Lets check out answer. What is 31-7? 31-7 is 24. Now we know our work was correct
