What is the equation of a line that has a slope of 2 and passes through point (-6, 3)?
Step-by-step explanation:
m= 2
x1 = -6
y1 = 3
Applying the formula,
y-y1 = m(x-x1);
we have,
y - 3 = 2(x -(-6))
y- 3 = 2(x + 6)
y - 3 = 2x + 12
y -2x -3 -12 = 0
y -2x -15 = 0
Therefore the equation of the line is;
2x - y + 15 = 0

David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use the variable a for Aaron's score.
Answer:
Aaron's bowling score is 30
David's bowling score is 54
Step-by-step explanation:
The variable representing Aaron's score is = a
The variable representing David's bowling score = d
The sum of their scores is 84.
= a + d = 84...... Equation 1
David's bowling score is 6 less than 2 times Aaron's score.
d = 2a - 6
Substituting 2a - 6 for d in Equation 1
a + 2a - 6 = 84
3a - 6 = 84
3a = 84 + 6
3a = 90
a = 90/3
a = 30
Hence, Aaron's bowling score is 30
d = 2a - 6
d = 2(30) - 6
d = 60 - 6
d = 54
David's bowling score is 54

Oil is pumped into a tank at a rate of Q(t)=45-t gallons per minute where time is t is measured in minutes how many gallons are in the tank after 30 minutes
Answer:
15 gallons
Step-by-step explanation:
Given that:
Pumping rate is modeled by the equation :
Q(t)=45-t gallons per minute ; where t is in minutes
Number of gallons in tank after 30 minutes ;
Q(t)=45-t
Q(30) = 45 - 30
Q(30) = 15
Hence, Number of gallons in tank after 30 minutes is 15 gallons

You can solve the equation 2x + 7 = 1 - x by graphing y = 2x + 7 and y = 1 - x and finding the point of intersection
Answer:
x = -2
Step-by-step explanation:
You can also solve for the equation given.
2x + 7 = 1 - x
3x = -6
x = -2
The solution to the equation 2x + 7 = 1 - x is x = -2.
To solve the equation 2x + 7 = 1 - x by graphing, we can plot the two equations on a graph and identify the point where they intersect.
First, let's graph y = 2x + 7 and y = 1 - x on the same coordinate system.
The equation y = 2x + 7 represents a straight line with a slope of 2 and a y-intercept of 7.
The equation y = 1 - x represents a straight line with a slope of -1 and a y-intercept of 1.
Plotting these lines, we can see that they intersect at a specific point on the graph. The coordinates of this point represent the solution to the equation 2x + 7 = 1 - x.
By visually inspecting the graph, we can determine the point of intersection, which is approximately (-2, 3). This means that x = -2 is the solution to the given equation.

A jeweler wants to make 14 grams of an alloy that is precisely 75% gold.. The jeweler has alloys that are 25% gold, 50% gold, & 82% gold. Choose 2 different alloys that can be used to create one that is 75% gold. pls try to explain with a system of equations ; ;
Given that the jeweler has alloys that are 25% gold, 50% gold, and 82% gold.
As he wants to make 14 grams of an alloy by adding two different alloys that is precisely 75% gold, so one alloy must have a percentage of gold more than 75%.
One alloy is 82% gold and, the second can be chosen between 25% gold, 50% gold, so there are two cases.
Case 1: 82% gold + 50% gold
Let x grams of 82% gold and y grams of 50% gold added to make x+y=14 grams of 75% gold, so
75% of 14 = 82% of x + 50% of y
[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times y \\\\[/tex]
[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times (14-x)[/tex] [as x+y=14]
[tex]\Rightarrow 75 \times 14 = 82 \times x + 50 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 50 \times14-50\times x \\\\\Rightarrow 75 \times 14 = 32 \times x + 50 \times14 \\\\\Rightarrow 32 \times x =75 \times 14 - 50 \times14 \\\\[/tex]
[tex]\Rightarrow x =(25 \times 14)/32=10.9375[/tex] grams
and [tex]y = 14-x= 14-10.9375=3.0625[/tex] grams.
Hence, 10.9375 grams of 82% gold and 3.0625 grams of 50% gold added to make 14 grams of 75% gold.
Case 2: 82% gold + 25% gold
Let x grams of 82% gold and y grams of 25% gold added to make x+y=14 grams of 75% gold, so
75% of 14 = 82% of x + 25% of y
[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times y \\\\\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times (14-x) \\\\ \Rightarrow 75 \times 14 = 82 \times x + 25 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 25 \times14-25\times x \\\\\Rightarrow 75 \times 14 = 57 \times x + 25 \times14 \\\\\Rightarrow 57 \times x =75 \times 14 - 25 \times14 \\\\[/tex]
[tex]\Rightarrow x =(50 \times 14)/57=12.28[/tex] grams
and [tex]y = 14-x= 14-12.28=1.72[/tex] grams.
Hence, 12.28 grams of 82% gold and 1.72 grams of 50% gold added to make 14 grams of 75% gold.

One week gas $1.25 gallon the next sweet gas was $1.50 per gallon by what percentage to the price increase
Answer:
20%
Step-by-step explanation:
The first step is to calculate the increase
= 1.50-1.25
= 0.25
Therefore the percentage increase can be calculated as follows
= 0.25/1.25 × 100
= 0.2 × 100
= 20%

Answer:
The original length of the new candle is 10 inches
Step-by-step explanation:
The form of the linear function is y = m x + b, where
m is the slope of the lineb is the y-intercept value y at x = 0∵ L represents the length of the candle remeaning unburned in inches
∵ t represents the time after the candle was lit in hours
∵ The relationship between L and t is linear
→ Put it in the form of the equation above
∴ L = m t + b, where b is the original length of the new candle
→ Use the table to find m
∵ m = [tex]\frac{L2-L1}{t2-t1}[/tex]
∵ (1, 9) and (6, 4) are two points in the given table
∴ t1 = 1 and L1 = 9
∴ t2 = 6 and L2 = 4
→ Substitute them in the rule of m above
∵ m = [tex]\frac{4-9}{6-1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1
∴ m = -1
→ Substitute it in the equation above
∵ L = -1(t) + b
∴ L = -t + b
→ To find b substitute t by 1 and L by 9
∵ 9 = -(1) + b
∴ 9 = -1 + b
→ Add 1 to both sides
∵ 9 + 1 = -1 + 1 + b
∴ 10 = b
∵ b is the original length of the new candle
∴ The original length of the new candle is 10 inches
