1) An airplane is at 10,000 feet above the ground. It needs to fly higher to reach the regular flying height. It increases its height at a constant rate of 2,000 feet per minute. How high will the plane be in 10 minutes?
Answer:
20000
Step-by-step explanation:
Answer: 30,000 feet
Step-by-step explanation: We start with the 10,000 feet original height. From there, we can take 2,000 feet per minute and multiply it by 10 minutes. That gets us 20,000 feet. Add 20,000 to our original 10,000 and we get 30,000.

what is the answer for k=6x+100
Answer:
x = k/6 - 50/3
Step-by-step explanation:
K=6x+100
--> Swap sides so that all variable terms are on the left hand side.
6x+100=k
--> Subtract 100 from both sides.
6x=k−100
--> Divide both sides by 6.
6x/6 = k-100/6
--> Dividing by 6 undoes the multiplication by 6.
x = k-100/6
--> Divide k−100 by 6.
Answer : x = k/6 - 50/3
Hope this helps you!

Answer:
The answer is the second option
Step-by-step explanation:
All you have to do is replace x with the data given.
Example: f(x) = 3[tex]x^{2}[/tex] - 6
x = 0 => f(x) = 3 x [tex]0^{2}[/tex] - 6 = 3 x 0 - 6 = -6
x = 1 => f(x) = 3 x [tex]1^{2}[/tex] - 6 = 3 x 1 - 6 = 3 - 6 = -3
x = 2 => f(x) = 3 x [tex]2^{2}[/tex] - 6 = 3 x 4 - 6 = 12 - 6 = 6

Answer:
RS = 80°
Step-by-step explanation:
The sum of the arcs of a circle is 360°.
RS +ST +TR = 360°
RS = 360° -ST -TR = 360° -130° -150°
RS = 80°

The difference between two times a number and eight is twenty two. What is twice the number?
Answer: 30
Step-by-step explanation:
2x -8 = 22
2x = 22 + 8
2x = 30
Divide both sides by 2
X = 15
Twice of x
2 x X = 2 x 15 = 30

find the slope of the line that passes through the points (-2 3 )and( 4 3)
Step-by-step explanation:
Given points,
( -2 , 3) and (4,3)
we know,
slope = y_2 - y_1 / x_2 - x_1
so according to it we got,
→ (3 - 3)/4 - (-2)
→ 0/6
hope this answer helps you dear! take care.
Hello!
To find the slope when we have 2 points, we use the following formula:
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
m=[tex]\frac{3-3}{4-(-2)} \\\frac{0}{6} \\0[/tex]
Here's something for you to remember:
When the y-coordinates of two points are the same, the slope is 0.Hope it helps!

the point (-2,6) is on a line with a slope of 3/4. If the point -8,k) is also on the same line what is the value of k
For a point with a slope 3/4 and which passes through the points (-2, 6) and (-8, k), the value of k is 1.5
The line passes through the points (-2, 6) and (-8, k)
That is, [tex]x_1=-2, y_1=6, x_2=-8, y_2=k[/tex]
The slope of the line, m = 3/4
The formula for calculating the slope of a line is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute [tex]x_1=-2, y_1=6, x_2=-8, y_2=k, m = \frac{3}{4}[/tex] into the formula above
[tex]\frac{3}{4} = \frac{k-6}{-8-(-2)} \\\\\frac{3}{4} = \frac{k-6}{-8+2}\\\\\frac{3}{4} = \frac{k-6}{-6}\\\\-6(3)=4(k-6)\\\\-18=4k-24\\\\4k=-18+24\\\\4k=6\\\\k=\frac{6}{4} \\\\k=1.5[/tex]
Therefore, the value of k is 1.5

Which expression shows the distance on the number line between −3 and −10 ?

Step-by-step explanation:
Anything number raised to the zero power is
Answer:
It is equal to 1 when raised to the zero power.
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Any number raised to the zero power equals 1. This is by definition to make the rules of exponents work.
Look at this example:
Any number (except zero) divided by itself equals 1.
For example, 25/25 = 1,
but 25 = 5²,
so 25/25 = 5²/5²
The rule of dividing two powers with the same base is to use the same base and subtract the powers.
5²/5² = 5^(2 - 2) = 5^0
By the rule of exponents, 5²/5² = 5^0,
but we saw above that 5²/5² = 25/25 = 1, so
5^0 must equal 1.
This led to the following definition of zero exponent.
Definition:
For any number a, a^0 = 1.
Use the model to find the missing number in the pair of equivalent expressions.
