Answer:
Statement Two: The y-intercept of Function A is less than the y-intercept of Function B
Step-by-step explanation:
The y-intercept of Function A is -1
To calculate the y-intercept of Function B we first need to determine the slope.
The formula for slope is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex] [tex]\frac{4-2}{9-3} =\frac{2}{6} =\frac{1}{3}[/tex]
Now that we have the slope (1/3 x) we can find the y-intercept
[tex]b=y-mx[/tex]
[tex]b=0-(\frac{1}{3})(-3)[/tex]
[tex]b=1[/tex]
1 > -1, so Statement Two is true
plz mark me brainliest. :)
Use the Distributive Property to solve the problem. [Example: 4(6+3) = 4(6)+4(3) = 24 + 12 = 36] 9(8 + 4)
(sorry for spamming these questions, its part of an assignment i HAVE to do well on to raise my horrible math grade)
please let me know if you need help on anything else.
4(6+3)=4(6)+4(3)=24+12=36.
multiply 4(6) and 4(3).
4x6=24 4x3=12
24+12=24+12=24+12=36
24+12=36
9(8+4)
72+36=108

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6

how many solutions do linear equalities have?
Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

A circle has a diameter of 14 ft. What is the area of the circle? (use 3.14 for )
A. 43.96 ft²
B. 87.92 ft²
C. 153.86 ft²
D. 615.44 ft²
Answer:
answer is C. 153.86ft^2
Answer:
C 153.86ft²
Step-by-step explanation:
The formula is πr²
This mean you first find the radius of the circle which is half of the diameter. so for this circle the radius is 7ft.
Now plug everything in the formula and solve
3.14×7²
Following bedmas you would do exponents first. 7²=49
Now do 3.14×49 which is 154.86ft²

Inequality shows a relationship between two numbers or two expressions.
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
Example:
2 < 4
2x < 10
3x > 18
We have,
[tex]\frac{k}{-2}[/tex] ≤ 4
We will make an inequality in terms of k on one side.
Multiply -2 on both sides.
k ≤ -2 x 4
k ≤ -8
Thus,
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.
