Answer:
We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,
mACE = mECD
Next, we look at the choices
mECD = mECB > This not possible since ray CD is between the two angles
mACE = mACD > This is still not possible since ray CE is between the two angles
mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.
mECD = mACD > This is not possible since ray CE is between the two rays
The answer is the third option

what is AC?
is it
A. 4
B.7.5
C 5
D. 3
Step-by-step explanation:
your answer is C 5. also to find the answer by yourself get a ruler then measure the big one then the little one in mm. Then you can check how much larger they are then each other. In this case it is dilated to be twice the size. you call tell in this case by looking at the measurements it already gives you as you can see they both have the same labeled side, 3 and 6. 3 times 2 = 6 therefore it's twice the size

What is the equation of the line that passes through the point (7,2) and has a slope of 1
Answer:
y=x-5
Step-by-step explanation:
For this, use point-slope formula, which is (y-y1)=k(x-x1), in which k is slope.
Now, substitute in your values. (y-2)=1(x-7)
Then, since you got y-2=x-7, add 2 to both sides.
You get y=x-5
y = x +5 is the equation of the line that passes through the point (7,2) and has a slope of 1.
What is an equation of a line?The equation of a straight line is y=mx+c where m is the gradient and c is the height at which the line crosses the y -axis, also known as the y-intercept. There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
given, a line that passes through the point (7,2) and has a slope of 1
Since the Slope of the line = 1
From the slope-intercept form of the line
y = mx + c
thus, the Equation of the line
y = 1 * x + c
y = x + c
Since this line passes through coordinates (7, 2 ) this point will satisfy the equation
7 = 2 + c
c = 5
hence, the equation of a line
y = x +5
therefore, the equation of the line that passes through the point (7,2) and has a slope of 1 is y = x +5.

A marching band stands in a triangle formation. The drum major stands at A, one of the vertices of the triangle. The whole formation marches 3 units left and 5 units up. They then march 2 units left and 2 units up. After the movement, what coordinates will the drum major be standing on? A. (11, 3) B. (11, 11) C. (1, 11) D. (1, 3)
Answer:
D. (1, 3)
Step-by-step explanation:
Based on the image uploaded, during the first march, move point A, 3 units left, the new position will (3, -4), then move point A again 5 units up, the new position will be (3,1).
From second march move point A 2 units left, the new position will be (1,1), finally move point A 2units up, the new position and last position will be (1, 3).
Thus, the drum major be standing on (1, 3)

Triangle DEF is formed by connecting the midpoints of the sides of triangle ABC. The lengths of the sides of DEF are shown. What is the length of BC?
Answer:
may be it's helpful✌️..........
Applying the triangle midsegment theorem, the length of BC is: 8.
The Triangle Midsegment Theorem?Based on the triangle midsegment theorem, there are three midsegments in every triangle.The midsegments are parallel to each of their corresponding third sides.Length of midsegment = half of the length of the third side.Given:
DF = 4 (midsegment)
BC = ? (Third side).
Therefore,
BC = 2(DF)
BC = 2(4)
BC = 8
Therefore, applying the triangle midsegment theorem, the length of BC is: 8.

Answer:
No; equation
Step-by-step explanation:
2x+5 = 10 is not an expression rather it's an equation because it has an equal sign. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

A function assigns the value of each element of one set to the other specific element of another set. The value of f(8) is 5.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The function that is given is mentioned below. Now, the value of the function can be found as shown below.
A.) f(-10)=?
When the value x is -10, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-10) = 2(-10)+1\\\\f(-10) = -20+1 = -19[/tex]
B.) f(2) = ?
When the value x is 2, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(2) = 2^2 = 4[/tex]
C.) f(-5)=?
When the value x is -5, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-5) = 2(-5)+1\\\\f(-5) = -10+1 = -9[/tex]
D.) f(-1)=?
When the value x is -1, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(-1) = (-1)^2 = 1[/tex]
E.) f(8)=?
When the value x is 8, it will lie in the third category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x-3\\\\f(8) = 8-3 = 5[/tex]
