Answer: The initial elevation of the plane was 8.75 miles.
Step-by-step explanation:
Suppose that the initial elevation of the plane is E.
Then the plane descends 3.5 miles.
Then the new elevation of the plane will be:
E - 3.5 miles.
Now, we know that the new elevation of the plane is 5.25 miles, then:
E - 3.5 miles = 5.25 miles.
Now we need to solve this for E.
To solve this, we can add the same number to both sides of the equation, so we can add 3.5 miles to both sides to get:
(E - 3.5 miles) + 3.5 miles = 5.25 miles + 3.5 miles
E + (3.5 miles - 3.5 miles) = 5.25 miles + 3.5 miles
E = 8.75 miles.
The initial elevation of the plane was 8.75 miles.
The point (3,-1) is on the line by which equation below?
Answer:
D. y = x - 4
Step-by-step explanation:
Given the following data;
Points (x, y) = (3, -1)
To find the equation of line;
First of all, we would determine the slope of the graph.
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {5 - 5}{5 - 5} [/tex]
Slope, m = 1
Generally, the equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
Using points (x, y) = (3, -1)
-1 = 1*3 + c
-1 = 3 + c
c = -1 - 3
Intercept, c = -4
Therefore, the equation of line becomes;
y = x - 4.

12g=12(2/3g-1)+11
Answer:
g= -0.25 or g= -1/4 (i think)
Step-by-step explanation:
Answer:
-1/4
Step-by-step explanation:
12g = 12(2/3g -1)+11
step 1
take care of the parentheses
12g=( 24/3 g - 12 )+11
step 2
try to simply to make your life easy
12g= 8g -12 +11
step 3
put gas together on one side left side
12g-8g = -12+11
4g= -1
g = -1/4

What is another way to write the equation 7/8 x 3/4= -6? (Look at picture! Pls hurry)
Answer:
Step-by-step explanation:
Well it doesn't help you very much, but the answer is A. What this does is separates 7/8 x so that (x/8) sits by itself. After you subtract 3/4 from both sides, you can divide both sides by 7. When you do that, you get x/8 = something, but the fractions are going to be awkward at best. I'll just do a very quick run through
7(x/8) = -6 - 3/4
7(x/8) = - 6.75 Divide by 7
x/8 = 0.9642 Multiply by 8
x = 8 * 0.9642
x = 7.7143
If you have $3250 how many board feet can you buy if the cost per board foot is $2.29?
Answer:
If i am right i think its 1419
Step-by-step explanation:
3250/2.29= about 1419
Answer:
1419.21= 1419
Step-by-step explanation:
Divide the amount of money you have with the cost price of what you want to buy.
$3250/$2.29=1419.213974
The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.
Therefore = 1419

3) Let h(x)= |2x|-4. Find h(x) when x = -7.
a) -10
b) 10
c) -13
d) 13
Answer:
[tex]h(x) = 10[/tex]
Step-by-step explanation:
Given
[tex]h(x) = |2x| - 4[/tex]
[tex]x = -7[/tex]
Find h(x)
Substitute -7 for x
[tex]h(x) = |2*-7| - 4[/tex]
[tex]h(x) = |-14| - 4[/tex]
Absolute values return positive. So:
[tex]h(x) = 14 - 4[/tex]
[tex]h(x) = 10[/tex]

12-6=6
6=6 which is true
Answer:
A. (4, -3)
Step-by-step explanation:
substitute x and y for 4 and -3 so the equation would be 3(4) + 2(-3) = 6 and 4 times 3 = 12 and 2 times -3 = -6 so then the equation would be 12 + (-6) = 6 or 12 - 6 = 6. Therefore, the answer A is correct
