Answer:
y=4x-2
Step-by-step explanation:
y=mx+b
plug in known variables
6=(4)(2)+b
simplify
b=-2
plug in m and b
y=4x-2
Find the equation of the line shown.
Answer:
[tex]\huge\boxed{y=-\dfrac{1}{4}x+2}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept (0, b)
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex](x_1;\ y_1);\ (x_2;\ y_)[/tex] - points on the line
From the graph we have two points (look at the picture)
[tex](4;\ 1)[/tex] and [tex](0; 2)\to b=2[/tex]
Calculate the slope:
[tex]m=\dfrac{2-1}{0-4}=\dfrac{1}{-4}=-\dfrac{1}{4}[/tex]
Put the values of [tex]m[/tex] and [tex]b[/tex] to the equation of a line:
[tex]y=-\dfrac{1}{4}x+2[tex]
what is slope intercept form?
Answer:
y=mx+b

what is this Find the value of |-6| - 3(42 - 1).
Answer:
-117
Step-by-step explanation:
The absolute value cancels out the negative sign for the 6.
6 - 3(42-1)
= 6 - 3*41
= 6 - 123
= -117

Phillipe says he cannot simplify the expression 5^c • 2^c. Complete the statement about Phillipe's claim.
Answer:
Step-by-step explanation:
[tex]a^{m} * b^{m}[/tex] = [tex](ab)^{m}[/tex]
Yes, he can!!
[tex]5^{c} * 2^{c} = (2 * 5 )^{c}[/tex] = [tex]10^{c}[/tex]
For example,
2³ × 3³ = 8 × 27 = 216
6³ = 216
The expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Phillips says he cannot simplify the expression [tex]5^c.2^c[/tex]
She can not simplify the expression because the bases of the expression are not same, and this expression is same as
[tex]5^c.2^c\\\\= (5.2)^2\\\\=10^c[/tex]
Hence, the expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]

Jason has a lemonade stand but he already made $26 he charges his customers one dollar per lemonade Kaylee has a lemonade stand where she made $16 and she charges the customers two dollars per lemonade which equation shows the number of lemonade, eggs, Kaylee needs to sell to make a higher profit than Jason. A. 26-x<16-2x. B. X+26<2x+16 C. 26+2x>16+x D. 16x+2>26x+1
Answer: B. X+26<2x+16
Step-by-step explanation:
Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.
Given: Jason has made $26. he charge $1 per lemonade.
Total earnings after x lemonades = $26+($1) x
= $(26+x)
Kaylee has made $16. he charge $2 per lemonade.
Total earnings after x lemonades = $16+($2) x
= $(16+2x)
Required inequality : (16+2x)> (26+x)
i.e. correct option is B.

Last summer, the Abrams family had a 30-gallon baby pool that they could fill in just 2
minutes. This summer, they purchased a larger kiddie pool that holds 150 gallons of water.
If the Abrams fill the larger pool at the same rate, how long will it take to fill it?
Answer:
10 mins
Explanation:
Because it takes 2 minutes to fill a 30 gal pool, and 150/30=5, 2 x 5 = 10 giving you the answer of 10 mins to fill a 150 gal pool.
Time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.
Given that, the Abrams family had a 30 gallon baby pool that could fill in just 2 minutes.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, rate of filling the pool = 30/2
= 15 gallons per minute
So, time taken to fill 150 gallons of water
= 150/15
=10 minutes
Therefore, time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.

The angles of a triangle add to 180, add the angles and solve for x
Answer:
x = 14
Step-by-step explanation:
3x + 9 + 5x - 1 + 4x + 4 = 180 because triangles have 180 degrees
12x + 12 = 180
180 - 12 = 168
12x = 168
168/12 = 14
x = 14
