Which equation represents the graphed function? O y = -3x + 3 O y = 3x - 3 O y = 3x - 2 / 2 O y=-*x+3
Answer:
y=1/3x+3
Step-by-step explanation:
the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3
we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1
then we substitute the m and c then tha is the equation.

Solve for a. 2.4a + 8 = 27.2
Answer:
Hello! answer: a = 8
Step-by-step explanation:
2.4 × 8 = 19.2
19.2 + 8 = 27.2 therefore a = 8 hope that helps!
Answer:
a = 8
Step-by-step explanation:
2.4a + 8 = 27.2
2.4a + 8 - 8 = 27.2 - 8
2.4a = 19.2
2.4a ÷ 2.4 = 19.2 ÷ 2.4
a = 8
Mark, Jessica, and Nate each downloaded music from the same website. Mark downloaded 10 songs in total consisting of pop, rock, and hip hop. Jessica
downloaded five times as many pop songs, twice as many rock schgs, and three times as many hip hop songs as Mark. She downloaded 28 songs total.
Nate downloaded 20 songs total with three times as many pop songs, three times as many rock songs, and the same number of hip hop songs as Mark.
Which system of equations represents their music choices?
Answer:
Mark:
x + y + z = 10
Jessica:
5x + 2y + 3z = 28

find the distance between each pair of points
(7 1/2, 3 1/4) and (7 1/2, 9 1/2)
Answer:
d=13
Step-by-step explanation:
D = √(x2 - x1)2 + (y2 - y1)2
D = √(-6 - (-8))2 + (1 - 4)2
D = √(-6 + 8)2 + (-3)2
D = √(2)2 + (-3)2
D = √4 + 9
D = √13

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of sides? A.20cm B.16cm C.22cm D.23cm
Complete question:
If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm
Answer:
B. 16 cm
Step-by-step explanation:
Given;
two lengths of the triangle as 15 cm and 4 cm
The length of the third side of the triangle must be less than the sum of the two given sides.
Length of third side < 15 cm + 4 cm
Length of third side < 19 cm
The only option less than 19 cm is B. 16 cm
Therefore, the correct option is B. 16 cm

Solve using the quadratic formula. Approximate answers to the nearest tenth.
Help
Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).
Given that a = two and b = 3, what is the value of (ab)?
Answer:
(ab) = 6
Step-by-step explanation:
a = 2 and b = 3
So, (2(3)) or 2 x 3 = 6

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25
