Find the slope of the line between the points (1, 4) and (-1,6)
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (- 1, 6)
m = [tex]\frac{6-4}{-1-1}[/tex] = [tex]\frac{2}{-2}[/tex] = - 1
which of these comparisons is correct?
A. -2 < -5
B. 0 > 2
C. 4 > -4
D. -6 < -5
is -10/3 greater than or less than negative square root of 9
Answer:
Greater :D

Step-by-step explanation:
Balloon A is released 5 feet above the ground. Balloon B is released at ground level. Both balloons rise at a constant rate. Which situation can you represent using an equation of the form y = kx? Explain.
Answer:
The situation of balloon B
Step-by-step explanation:
Balloon A is released 5 feet above the ground and our ground level be 0 feet. Let k be the rate at which it rises and t the time it takes to rise. Its height y, above the ground after time x is y = kt + 5
For Balloon B since it is released at ground level at which ground level is taken as 0 feet, let t be the time it takes to rise above the ground and k the rate at which it rises above the ground. Its height y above the ground after tie x is y = kt
Since the expression for Balloon B is y = kt and the expression for Balloon A is y = kt + 5, only the situation of Balloon B can be expressed in the form y = kx.
This is because the rate of rise of Balloon B follows a direct proportionality while the rate of rise of Balloon follow a joint proportionality since it starts from a point other than ground level.

Answer:
b= 3
d= 10/7
Step-by-step explanation:
Basically what you do is 12/6 and 10/7 for d, because it is the greatest and least on both sides. You do the same for b so it would be 10-7=3 and 12-6=6

If an angle of a parallelogram is two-third of
its adjacent angle, the smallest angle of the
parallelogram is
(a) 54°
(b) 72°
(c) 81°
(d) 108°
Answer:
We know that in a parallelogram two opposite angles are equal -
[tex] \\ \implies \sf \: 2x + 2y = 360 {}^{ \circ} \\ \\ \\ \implies \sf \: x + y = 180 {}^{ \circ} \qquad \quad \: (i) \\ [/tex]
Given -
angle x is equal to the two - third of it's adjacent angle y.[tex] \\ \implies \sf \: x = \frac{2}{3} y \\ \\ \\ \implies \sf \frac{x}{2} = \frac{y}{3} = k \\ \\ \\ \qquad \sf \small \underline{ x = 2k \: \: \& \: \: y = 3k} \\ [/tex]
Now, by using equation (1) :
[tex] \\ \implies \sf \: 2k + 3k = 180 \\ \\ \\ \implies \sf \: 5k = 180 \\ \\ \\ \implies \sf \: k = \frac{180}{5} \\ \\ \\ \large{ \boxed{ \sf{k = {36}^{ \circ} }}} \\ [/tex]
Now, by putting the value of k in x and y.
x = 2k = 2 × 36 = 72° y = 3k = 3 × 36 = 108°Therefore, the right option and smallest angle is b) 72°.

Answer:
[tex]\boxed{\tt A. \angle8 \ and \angle 7}[/tex]
Step-by-step explanation:
Supplementary angles are angles that add to 180 degrees.
Let's examine the answer choices.
A. ∠8 and ∠7
⇒ These angles are on a straight line together, so they are supplementary.
B. ∠5 and ∠1
⇒ These angles have no relation to each other. They are on different lines that are not parallel.
C. ∠7 and ∠4
⇒These angles also have no relation to each other.
D. ∠2 and ∠4
⇒ These angles are vertical, but not supplementary.
The correct answer is A. ∠8 and ∠7
If g(x) = x² + 2, find g(3)

Please help. FLVS.
Answer:
g(3) = 11Step-by-step explanation:
g(x) = x² + 2
To find g(3) , substitute the value of x that's 3 into g(x) , that is for every x in g (x) replace it with 3
That's
g(3) = 3² + 2
= 9 + 2
We have the final answer as
g(3) = 11Hope this helps you
first year of high school heh need a little help
Answer:
(12 + 3x)x
Step-by-step explanation:
(12 + 3)x = 12x + 3x = 15x
(12 + 3x)x = 12x + 3x²
15x
12x + 3x = 15x
They all equal 15x except for (12 + 3x)x

A farmer applies different fertilizer to his wheat crops to see which will make his plants grow the highest.
What is the independent variable?
Answer:
highest )hope this helps :)
Step-by-step explanation:
Answer:
The crop
Step-by-step explanation:
As the type of fertilizer changes it can not be the independent variable. Since nothing else (except the farmer) is referenced we can deduct that the crop is the independent variable.

Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Check all that apply. The associative property allows us to change the grouping of terms that are added together. When changing the grouping, the order of the terms stays the same; only the parentheses change position. The expression a + (b + c) + d is an equivalent expression. The expression ab(cd) is an equivalent expression. The expression (a+ b) + c + d is an equivalent expression. The expression a + b(c + d) is an equivalent expression.
Answer:
a.The associative property allows us to change the grouping of terms that are added together.
b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.
c.The expression a + (b + c) + d is an equivalent expression.
e.The expression (a+ b) + c + d is an equivalent expression.
Step-by-step explanation:
The correct statements are statement first, statement second, statement third, and statement fifth are correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
As we know,
The associative property allows us to change the grouping of terms that are added together.
= a + (b + c)
= (a + b) + c
The correct statements are:
