Answer:
[tex]y=2x+7[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-\frac{1}{2}x[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -1/2
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: 2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2, 3) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 2 and the point (-2, 3)
[tex]y-3=2\left(x-\left(-2\right)\right)[/tex]
[tex]y-3=2\left(x+2\right)[/tex]
Add 3 to both sides
[tex]y-3+3=2\left(x+2\right)+3[/tex]
[tex]y=2x+7[/tex]

Solve for Y.

6=2(y)+2(2)
6=2y+4
-4 -4
2=2y
-- --
2 2
divide two in both sides to get y by itself
y=1
Answer:
y = 1
Step-by-step explanation:
6 = 2 (y + 2)
Distribuite:
2 * y = 2y
2 * 2 = 4
2y + 4 = 6
Use additive inverses. The additive inverse of addition is subtraction.
Subtract 4 from both sides:
2y + 4 - 4 = 6 - 4
6 - 4 = 2
2y ÷ 2 = 2 ÷ 2
2y ÷ 2 = y
2 ÷ 2 = 1
To check our answer we multiply how much y is (which is 1) by 2.
2(1) + 4 = 6
2 * 1 = 2
2 + 4 = 6.

Luis does not know how old your grandfather Fernando is, but he does know the age of his father john is 20 years younger than him. Luis was 15 years old and was born when his father was 35 years old. Luis uncle is 3 years younger than his dad. Analyze the two equations bellow that represents the ages of the person describe. X+20=y Y-20-3=z what do each variable represents
Answers
Answer: X= John's age , Y= Fernando's age, Z = Age of Luis uncle
Step-by-step explanation:
Given: John is 20 years younger than fernando.
i.e. John' age + 20 = Fernando's age
So in the given equation "X+20=Y " , X= John's age and Y= Fernando's age.
From this , John's age: X= Y-20 (i)
Also, Luis uncle is 3 years younger than his dad( John).
Age of Luis uncle = John's age -3
=X-3
= Y-20-3 [From i]
So in the given equation Y-20-3=Z , Z = Age of Luis uncle
The carnival fundraiser at Westville Elementary School raised $300 on Friday. On Saturday, the carnival will raise 480 percent of that amount. Which statements are true about the amount of money that the carnival will raise on Saturday? Check all that apply.
Answers
The missing options in the question are:
a.) The answer will be less than $300 because 100 is less than 480.
b.) The answer will be greater than $300 because 480 is greater than 100.
c.) (100)(3) = 300, so 480(3) is the amount of money that the carnival will raise on Saturday.
d.) 480 + 300 is the amount of money that the carnival raised on Saturday.
e.) The carnival raised $780 on Saturday.
f.) The carnival raised $1,440 on Saturday.
Answer:
The correct options are: (b), (c), (f)
Step-by-step explanation:
Given that:
The carnival fundraiser raised $300 on Friday
On Saturday, It was stated that the carnival fundraiser will raise 480 percent of the amount raised on Friday;
i.e.
= (480% × 300)
[tex]= \dfrac{480}{100} \times 300[/tex]
= 480 (3)
= $1440
So; we are to check the given option and choose the statements that are true about the amount of money that will be raised at the carnival on Saturday.
From the above explanation;
The true statements are:
The answer will be greater than $300 because 480 is greater than 100.
(100)(3) = 300, so 480(3) is the amount of money that the carnival will raise on Saturday.
The carnival raised $1,440 on Saturday.
