what is the slope of y = -x + 7
Answer:
slope m = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 7 ← is in slope- intercept form
with slope m = - 1

what is the measure of the line segment AB if D is between A and B, AD = 7, and DB = 12?
Answer:
Given AD = 7 and DB = 12, to find AB you need to add them
AB = 12+7
AB = 19
The measure of the line segment AB is 19 units.
What are the coordinates of midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}andy = \dfrac{q+n}{2}[/tex]
We are given that;
AD = 7, and DB = 12
Now,
To find the measure of the line segment AB, we need to use the segment addition postulate. The segment addition postulate states that if a point is between two other points on a line segment, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.
In this problem, D is between A and B, so we can apply the segment addition postulate and write:
AD + DB = AB
Substituting the given values of AD and DB, we get:
7 + 12 = AB
Simplifying, we get:
19 = AB
Therefore, by the given point the answer will be 19 units.

what is the y - intercept
Answer:
The y- intercept is 1
Step-by-step explanation:
Since the line crosses the y-axis at 1, the y-intercept is 1. Like the x-intercept. The line crosses the x-axis at um.. I would say about -1.5, so the x-intercept is -1.5.

Mya applied the distributive property to write the equivalent expressions below
45+ 72 - 9(5 + 9)
What is Mya's error?
Mya did not write the common factor in the correct place,
Mya wrote two expressions that are not equivalent
O Mya did not use the correct operations in the equation,
Mya used a factor that is not common to 45 and 72,
Answer:
Mya wrote two expressions that are not equivalent
Step-by-step explanation:
45 +72 does not equal to 9(5+9)
9(5+9) = 45 + 81
Answer:
D
Step-by-step explanation:
I dislike these kinds of questions. I could argue either of 2 answers - b and d.
b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.
d says she didn't use a common factor to both terms and that is true.
The actual answer is that she made a silly error which we all often do.
8 * 9 is 72
so the distributive property should be
9(5 + 8)
So, what's the answer? I would pick D, but hold your nose when you enter it.

What is the slope of the line parallel to 7x + 4y = -16?
Answer:
The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]
Step-by-step explanation:
Parallel lines have the same slopes and different y-intercepts
The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]
Let us use these rules to solve the question
∵ The equation of a given line is 7x + 4y = -16
→ Compare it with the form of the equation above
∴ a = 7 and b = 4
∵ The slope of the line = [tex]\frac{-a}{b}[/tex]
∴ The slope of the line = [tex]\frac{-7}{4}[/tex]
∵ Parallel lines have the same slope
∴ The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

9. Suppose GH = JK. HI = KI and QI = ZL. How can you prove that GHI is congruent to JKL ?
You can use SAS to prove the triangles are congruent.
You can use SSS to prove the triangles are congruent.
You can use SSA to prove the triangles are congruent.
There is not enough information to prove that the triangles are congruent.
Answer:
C. SSSStep-by-step explanation:
Since we are not given any angle measure and three side measure, we can prove these triangles congruent by SSS.
To prove triangle GHI and JKL are congruent, rule SSS is used.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
Different rules of congruency are as follows.
SSS (Side-Side-Side)
SAS (Side-Angle-Side)
ASA (Angle-Side-Angle)
AAS (Angle-Angle-Side)
RHS (Right angle-Hypotenuse-Side)
Given
Triangles GHI and JKL
GH = JK
HI = KI
QI = ZL
All three sides are equal in both triangles.
By side-side-side theorem,
ΔGHI ≅ΔJKL
Hence, by SSS theorem, it is proved the triangles are congruent.

Graph the line with slope 1/4 and y intercept -2
Answer:
y= 1/4x -2
Step-by-step explanation:
Y=mx+b
m is the slope
b is the y intercept
The equation of line is y= 1/4x -2 .
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
slope = 1/4 and y intercept = -2
Using slope- intercept form
y= mx + b
y= 1/4x + (-2)
y= 1/4x -2

What is the answer to this question?
Answer:
≈ 3.9 miles
Step-by-step explanation:
The third angle in the triangle is
180° - (53 + 78)° = 180° - 131° = 49°
Using the Sine rule in the triangle with distance from 2 being x, then
[tex]\frac{3}{sin49}[/tex] = [tex]\frac{x}{sin78}[/tex] ( cross- multiply )
x × sin49° = 3 × sin78° ( divide both sides by sin49° )
x = [tex]\frac{3sin78}{sin49}[/tex] ≈ 3.9 ( to the nearest tenth )
