Answer:

When finding the y-intercept it indicates that the x-coordinate will be zero.

So,when letting x=0 you will get

y=-3(0)+4

Hence,

y=4

Find the measure of the missing angle.<br> a<br> 66°

yanalaym [24]

Answer:

24°

Step-by-step explanation:

the total angle, made up from both a and 66°, is a mini-square, as you can see. this represents a right angle of 90°

thus, a and 66° combine to make 90°

a + 66° = 90°

subtract 66 from both sides to get a

a = 24°

PLEASE HELP!!

RSB [31]

Answer:

D.130°

Step-by-step explanation:

An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.

-Given that AC and BC are diameters, then $\angle AOB =\angle DOC$ since they are alternate angles.

$\angle AOB =\angle dOC=180\textdegree\\\\3x-70=x+10\\\\x=40\textdegree$

#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:

$(3x-70)+m\angle BC=180\\\\M\angle BC=180+70-3\times 40\\\\=130\textdegree$

Hence, mBC=130°

Eli read four more biographies than historical fiction book during the semester. He also read two fewer mysteries than historica

9966 [12]

Answer: Eli read 3 historical fiction books , 7 biographies and 1 mystery book.

Step-by-step explanation:

Let x be the number of historical fiction books Eli read.

Then, Number of biographies he read = x+4

Number of mysteries he read = x-2

If he read a total of eleven books during the semester , then we have the following equation :

$x+x+4+x-2=11$

$\\\\\Rightarrow\ 3x+2=11$

$\\\\\Rightarrow\ 3x=9$ (Subtract 2 from both sides )

$x=3$ (Divide both sides by 3)

Therefore , Number of historical fiction books Eli read = 3

Number of biographies he read = 3+4=7

Number of mysteries he read =3-2=1

Hence, Eli read 3 historical fiction books , 7 biographies and 1 mystery book.
