The y-intercept is the point (0,-4)
This is the y-intercept because this point has a zero for its x-coordinate, which indicates that this point is staying on the y-axis.
Answer:
68°
Step-by-step explanation:
ABD is a right angle and the measure of it is 90°
m<CBD + m<ABC = m<ABD
4x + 52° + 8x - 10 = 90° add like terms
12x + 42° = 90°
12x = 48°
x = 4
m<CBD is 4x + 52° replace x with 4
4×4 + 52 = 68°
Answer:
12
Step-by-step explanation:
Start by expanding the expression:
4(3x+5)
Distribute the 4 to each of the numbers in the parentheses
12x+20
The coefficient of x is basically what is being multiplied by x. In this scenario, we can expand 12x to be...
12*x
Which means that the coefficient of x is 12
6(2x+5)-6=0
(12x+30)-6=0
+6 +6
12x+30=6
-30 -30
12x=-24
/12 /12
x=-2
MC=2(-2)+5
MC=-4+5
MC=1
LM=11
MC=1
LC=-18
check the picture below.
the line QS is just a flat-line and therefore it has 180° on either side, so the angle QPR is 57°, as you see there, and since we know the diameter is 20, that simply means the radius of the circle is 10.
