Write the standard form of the equation of a line with a slope of 3 passing through the point (-5, -6).
Select one:
a. -x + 3y + 13 = 0
b. -3x + y - 9 = 0
c. 3x - y + 9 = 0
d. x - 3y - 13 = 0
Answers
Step 1: We need to first find the equation of the line in slope-intercept form by finding b, or the y-intercept.
[tex]-6 = 3(-5) + b\\\\-6 = -15 + b\\\\9 = b[/tex]
Step 3: We now need to write the equation of the line in slope-intercept form.
[tex]y = 3x + 9[/tex]
Step 3: Now we convert the above equation from slope-intercept form to standard form.
[tex]y = 3x + 9\\\\-3x + y = 9\\\\-3x + y - 9 = 0[/tex]
Our equation in standard form is: B. -3x + y - 9 = 0.

Suppose that y is inversely proportional to the 4th power of x, and that y=15 when x=5. What is y when x=7? Round your answer to two decimal places if necessary.
Answers
Answer:
y = 3.91 when x =7
Step-by-step explanation:
y = k / x⁴
Where,
k = constant of proportionality
y=15 when x=5
y = k / x⁴
15 = k / 5⁴
Cross product
15 × 5⁴ = k
15 × 625 = k
9,375 = k
What is y when x=7?
y = k / x⁴
= 9,375 / 7⁴
= 9,375 / 2401
= 3.9046230737192
Approximately
y = 3.91
Blake and Josh are both saving money for a new bike. The ratio of Blake's savings to Josh's savings is 3:1. If they have saved $400, how much has each boy saved?
Answers
Given:
Total savings = $400
Ratio of savings of Blake and Josh = 3:1
To find:
The saving of each.
Solution:
Let the savings of Blake and Josh are 3x and x respectively.
According to the question,
[tex]3x+x=400[/tex]
[tex]4x=400[/tex]
Divide both sides by 4.
[tex]x=100[/tex]
Now,
Savings of Blake = 3(100)=300
Savings of Josh =100
Therefore, the savings of Blake and Josh are $300 and $100 respectively.

a team of divers assembles at an elevation of -10 ft relative to the surface of the water. Then the team dives at a rate of the water. Then the team dives at a rate of -50ft/min. Write a rule that represents the teams depth d as a function of time t. What is the team's depth after 3 minutes?
Answers
Answer: The team will be 160 feet below sea level after 3 minutes.
Step-by-step explanation:
If the team is at -10 ft relative to sea level then it means that they are 10 feet below sea level, and if they also going -50 ft per minute, it also means that they are still going below sea level.
The rule will be, d= -50t -10
If t is the time, input 3 minutes into the equation for t and solve for d to find their depth.
d= -50(3) - 10
d= -150 - 10
d= -160

If two angles of a triangle measure 20 and 130 degrees, what is the measure of the third angle?
A.) 40°
B.) 50°
C.) 30°
D.) 60°
Answers
Answer:
c.) 30 degrees
Step-by-step explanation:
the sum of the angles of a triangle is 180 degrees
so if the third angle was x
then
x=180-(20+130)
x=180-150
x=30 degrees
The measure of third angle is 30 degree.
What is Angle Sum property?The total of a triangle's three internal angles is 180 degrees, as stated by the angle sum feature of a triangle. A closed shape with both inner and exterior angles, a triangle is created by three line segments.
Given:
Two angles are 20 and 130.
Using Angle sum property of triangle
<1 + <2 + <3 = 180
20+ 130 + <3= 180
150 + <3 = 180
<3 = 180- 150
<3 = 30
Hence, the third angle is 30 degree.

A car uses 8.4 liters of petrol for a 112 mile journey. When the tank is full, the car holds 54 liters of petrol. How far should the car be able to travel on a full tank of petrol.
Answers
Answer:
720 miles
Step-by-step explanation:
A car uses 8.4 liters of petrol for a 112 mile journey.
In 1 litres = [tex]\dfrac{112}{8.4}\ \text{miles}[/tex] of journey
We need to find far should the car be able to travel on a full tank of petrol i.e. 54 litres of petrol.
[tex]54\ l=\dfrac{112}{8.4}\times 54\\\\=720\ \text{miles}[/tex]
So, the car can travel 720 miles when it holds 54 lirres of petrol.

-y=7-5x
y=5x-7
∴m(slope)=5

Using no digits other than 5 and 8, make a 6-digit number, that has the properties below. If it is impossible, write so. Of course you may use each digit more than once. c A multiple of 5, but not a multiple of 15.
Answers
Answer:
Doing this would be impossible
Step-by-step explanation:
Doing this would be impossible. This is because the final digit and the first digit in the 6-digit number would always be a 5 or an 8. This means that the entire 6-digit number will either be completely divisible by both 5 and 15 or neither. Therefore not meeting the requirements that have been set. So in conclusion, this would be impossible to do by using only 5's and 8's as the single digits.
