Answer:
y = 6x + 4
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 )
Here m = 6 and given point (0, 4 ) ⇒ c = 4
y = 6x + 4 ← equation of line
y varies directly with x. y is 84 when x is 16. What is the constant of proportionality? (Write answer as improper fraction...Remember to reduce!)
Answer: 5 1/4
Step-by-step explanation:
We use the formula for direct proportion to solve the question since we are informed that y varies directly with x and that y is 84 when x is 16.
The formula will be:
y = kx
where,
y = 84
x = 16
We then slot the values into the formula
y = kx
84 = 16k
k = 84/16
k = 5 1/4
The constant of proportionality is 5 1/4

what is the mass of an object that weighs 7 kg and 50 N?
Answer:
7kg
Step-by-step explanation:
mass: amount of matter in a substance,
SI Unit: kg
It has nothing to do with N (weight) in this case so take the kg value as the mass
Answer:
0.71 kg
Step-by-step explanation:
a common equation in physics is w = mg
we can rearrange this to m = w/g
g is the acceleration of gravity: 9.81 m/s^2
w is the weight of the given equation of the object: 7 kg
so m = 7 kg ÷ 9.81 m/s^2
this gives us: m = 0.71 kg

310= -6.2f
I’m just struggling on this question;—;
Answer:
Step-by-step explanation:
sup. so what you're going to do is divide -6.2 on both sides to get f by itself
310/-6.2= -6.2f/-6.2
f=-50
Answer:
-50.
Step-by-step explanation:
310 = -6.2f
To solve for f we divide both sides of the equation by -6.2
310 / -6.2 = -6.2f / -6.2
f = -310/-6.2 = -50.

8. Which of the following is the 43rd term of the arithmetic sequence 3,0-3, ...?
A-117
B 120
C. -123
D. -126
Answer:
C
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 0 - 3 = - 3 , thus
a₄₃ = 3 + (42 × - 3) = 3 - 126 = - 123 → C
Answer:
C. -123.
Step-by-step explanation:
nth term = a1 + d(n - 1)
43rd term = 3 + -3(43-1)
= 3 - 126
= -123.

A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green marbles are in the jar
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles

Change 8 1/2 to an
improper fraction.
Answer:
17/2
Step-by-step explanation:
Answer:
17/2
Step-by-step explanation:
Improper fraction means no whole number. So, we have to change 8 to a fraction with a common denominator as 1/2. So, 8/1 = 16/2, plus the given 1/2, that's 17/2.
