write the equation of the line in fully simplified slope-intercept form
Answer:
y = 3x - 7
Step-by-step explanation:
Slope - Intercept Form : [tex]y = mx+b[/tex]
[tex]m[/tex] = slope
[tex]b[/tex] = y - intercept
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac3{1}[/tex]
= [tex]3[/tex]
So far: [tex]y = 3x + b[/tex]
Plug in a point from the graph, ex. (3,2)
[tex]2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7[/tex]
Equation : [tex]y = 3x - 7[/tex]

$65 for Unlimited Data $70 for Unlimited Data
Which of the following deals has the cheapest price per GB?
A.
Prepaid Single Phone Plan $35 for 6 GB
B.
Prepaid Single Phone Plan $45 for 16 GB
C.
Prepaid Family Plan 1 Person $30 for 1 GB
D.
Prepaid Family Plan 1 Person $50 for 16 GB
The data plan that has the cheapest deal is given by the ratio of the data
plan price to the GB allocated.
The deal that has the cheapest price per GB is B. Prepaid Single Phone Plan $45 for 16 GB.The given phone data plans are;
[tex]\begin{tabular}{|l|cl|}&Prepaid Single Phone Plan&Prepaid Family Plan\\ a&\$30 for 1 GB &\$30 for 1 GB\\b& \$35 for 6 GB & \$40 for 6 GB\\ c&\$45 for 16 GB&\$50 for 16 GB\\d & \$65 for Unlimited Data & \$70 for Unlimited Data\end{array}\right][/tex]
The price per GB are;
Plan a = $30 ÷ 1 = $30 per GB
Plan b = $35 ÷ 6 = $5.8[tex]\overline 3[/tex] per GB and $40÷ 6 = $6.[tex]\overline 6[/tex] per GB for Family Plan
Plan c = 45 ÷ 16 = $2.8125 per GB and $3.125 per GB
Plan d = $65 for Unlimited Data = 65 ÷ ∞ ≈ 0; $70 for Unlimited Data = 0
Therefore, the plan with the cheapest price per GB from the given option is option B. Prepaid Single Phone Plan $45 for 16 GB.

Melinda creates jewelry. After purchasing supplies, she had $150 left in her account. She sells five bracelets and a necklace making her new account total $235. If the necklace sold for $22. 50, which equation can be used to determine the sales price of the bracelets?.
The equation that can be used to determine the sales price of the bracelets is $22.5
Amount in her account = $150
Amount in her account after sales = $235
Change in account balance = $235 - $150
= $85
cost of necklace = $22.5
let
bracelet = x
necklace = y
The equation:
Total sales = 5x + y
85 = 5x + 22.5
85 - 22.5 = 5x
62.5 = 5x
x = 62.5/5
x = $12.5
Therefore, the cost of each bracelet is $12.5 and the cost of necklace is $22.5

X + X + 38= 180
2x = 180-38
2x = 142
X = 71°
Answer:
71
Step-by-step explanation:
The two line of length 21 defines that the base angles are equal.
so therefore.
38 degrees + x degrees + x degrees = 180
38 + 2x = 180
2x = 180 - 32
2x = 142
x = 71.

x/4 = 16
Hi there!
Since this is a one-step equation, we can solve it in one step.
This step is multiplying both sides by 4 to isolate x:
x=16*4
x=64
Therefore, x=64.
Hope it helps!
~GracefulGirlie
Good luck. :)
Answer:
X = 64
Step-by-step explanation:
x/4 = 16
Multiply both sides by 4
x = 16 x 4
Multiply 16 and 4 equals 64
