Solve by using elimination.
Answer:
The equations are not compatible
Step-by-step explanation:
y = -4x + 3
8x + 2y = 8
substitute for y:
8x + 2(-4x + 3) = 8
simplify:
8x - 8x + 6 = 8

Answer:
[tex]\sqrt{0.5}[/tex]
Step-by-step explanation:
cosx=adj/hyp
adj= [tex]\sqrt{2}[/tex]/2
hyp= r
cos(45)= ([tex]\sqrt{2}[/tex]/2)/r
[tex]\sqrt{2}[/tex]/2 = ([tex]\sqrt{2}[/tex]/2)/r
multiply both sides by r
([tex]\sqrt{2}[/tex]/2)r = [tex]\sqrt{2}[/tex]/2
divide both sides by [tex]\sqrt{2}[/tex]/2
r = 1
pythagorean theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a = [tex]\sqrt{2}[/tex]/2
b = y
c = r = 1
[tex](\sqrt{2}/2)^{2}[/tex] + [tex]y^{2}[/tex] = [tex]1^{2}[/tex]
[tex](\sqrt{2}/2)^{2}[/tex] = 2/4 = 0.5
0.5 + [tex]y^{2}[/tex] = 1
subtract 0.5 from 1
[tex]y^{2}[/tex] = 0.5
[tex]\sqrt{y^{2}}[/tex] = [tex]\sqrt{0.5}[/tex]
y = [tex]\sqrt{0.5}[/tex]
6) You go to dinner with some
friends. Your total bill was $56.32.
You have a coupon for 15%. How
much is your total cost if you leave
a 20% tip?
Answer:
$57.44
Step-by-step explanation:
1. subtract 15% from the bill with coupon:
$56.32 - ($56.32 x 0.15) = $47.87
2. add 20% to this new bill:
$47.87+(47.87 x 0.20) = $57.44

Find the correlation coefficient for the data. Round to the nearest hundredth.
the correlation coefficient for Alfonso survey is 0.36.
What is the correlation coefficient?
The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.
For the given situation,
The table below shows the values of the data x, y and the correlation calculations.
The formula of correlation coefficient is
[tex]r=\frac{n(\Σ xy)-(\Σ x)(\Σ y)}{\sqrt{[n\Σ x^{2} -(\Σ x)^{2} }] [n\Σ y^{2}-(\Σ y)^{2} ]}[/tex]
From the table substitute all the values.
⇒ [tex]r=\frac{(11)(98-(37)(26))}{\sqrt{[11(153)-37^{2} ][(11)(92)-26^{2} ] }}[/tex]
⇒ [tex]r=\frac{1078-962}{\sqrt{(1683-1369)(1012-676)} }[/tex]
⇒ [tex]r=\frac{116}{\sqrt{(314)(336)} }[/tex]
⇒ [tex]r=\frac{116}{324.81}[/tex]
⇒ [tex]r=0.357[/tex] ≈ [tex]0.36[/tex]
Hence we can conclude that the correlation coefficient for Alfonso survey is 0.36.

Miki already knew 4 appetizer recipes before starting culinary school, and she will learn 1 new appetizer recipe during each week of school. Write an equation that shows the relationship between the number of weeks x and the number of appetizer recipes y.
Answer:
y = 4 + x
Step-by-step explanation:
Appetizer recipe Miki knows already = 4
Appetizer recipe learnt per week = 1
x = number of weeks
y = total number of appetizer recipes Miki knows
Equation that shows the relationship between the number of weeks x and the number of appetizer recipes y

Tyler bought shoes for $72. The next week he noticed that the price went
up to $87. What was the percent increase (percent change)? Round your
answer to the nearest whole percent. *
Answer:
Percent increase is 21%
Step-by-step explanation:
Initial cost of shoes = $72
New price of shoes = $87
Increase in price of shoes = New price of shoes - Initial cost of shoes
= [tex]87-72[/tex]
= $15
Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100
= [tex]\frac{15}{72}(100)=20.8\%[/tex]
≈ 21%
So, percent increase is 21%
Which equation represents the proportional relationship between the cost, t, in dollars, of p pounds of wood bought? T=0.29pt = 0.29 p t=0.31pt = 0.31 p t=3.45pt = 3.45 p t=3.48p
Answer:
T = 0.29p
Step-by-step explanation:
From the table Given :
We can obtain the uint cost per pound of wood :
Cost of 12 pounds of wood = $3.48
Cost per pound = Cost / weight
Cost per pound = $3.48 / 12 = $0.29
Hence, the proportional relationship cost, T in dollars and p pounds of wood is ;
Cost = unit cost per pound * number of pounds
T = 0.29 * p
T = 0.29p
