Write your answer with no space and any fraction with “/“
Answer:
y+3=-1/2(x-1)
Step-by-step explanation:
Point-slope form of a line is given by the equation y - b = m(x - a), where,
(a, b) = is a point on the line
m = slope of the line.
A line that is perpendicular to y = 2x - 1 will have a slope value that is the negative reciprocal of the slope of the line.
The slope of the line, y = 2x - 1, is 2.
The negative reciprocal of 2 = -½.
The slope of the line that is perpendicular to y = 2x - 1 is -½.
Thus, m = -½.
Let's find the equation of the perpendicular if it passes through the point (1, -3).
Substitute (a, b) = (1, -3), and m = -1/2 into y - b = m(x - a).
Thus:
y - (-3) = -1/2(x - 1)
y+3=-1/2(x-1)
Which expression is a sum of a number and product. Answers. .8+3x .X+1 over 5 2(x-9). 5+x-4
Answer:
8 + 3x
Step-by-step explanation:
A product is a multiplication, such as 3 * 5, 2x, 4y.
3x is a product.
8 + 3x is the sum of the number 8 and the product 3x.
Answer: 8 + 3x
Add the expression
2x + 6 and 6x−1
Answer:
8x + 5
Step-by-step explanation:
You add like terms:

6 + (-1) = 5
Adding them up, you get:
8x + 5
The ratio of boys to girls at a movie is 4:5. If there are 15 girls, how many boys are at the movie?
Answer:
There are 12 boys at the movie.
Step-by-step explanation:
Key skills needed in order to solve: Proportions, Ratios, and Multiplication
1) The ratio is 4 boys : 5 girls --> It can be written as a fraction --> 4/5
2) If there are 15 girls, we need to find the number of boys. let's say x is the number of boys when there are 15 girls. The ratio would then be x/15
3) Make a proportion --> [tex]\frac{4}{5}[/tex] = [tex]\frac{x}{15}[/tex]
You have to cross multiply here. You do the first fraction's numerator times the second fraction's denominator, and the first fraction's denominator times the second fraction's numerator.
4) This means you have to do: 4(15) = 5(x)
5) Multiply it out --> 60=5x
6) Divide by 5 and you will get x=12
Therefore there are 12 boys at the movie.
Hope you understand and have a nice day!! :D

which expression are eguivalent to x+2y+x+2
Answer:
2x + 2y + 2
Step-by-step explanation:
x + 2y + x + 2
1. Combine like terms
x + x = 2x
there is only one y and one number w.out variable so you cannot combine anything else
2x + 2y + 2
and u cannot simplify it anymore

What is the perimeter of ABC with vertices A (-2,9) , B (7,-3) , C (-2,-3) in the coordinate plane?
A. 21 units
B. 15 units
C. 34 units
D. 36 units
9514 1404 393
Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.

Write and solve an inequality that represents the values of x for which the area of the rectangle will be at least 35 square feet.
Explanation:
There really is not enough information here. You have not indicated how x is related to the rectangle.Perhaps (as an alternative to the assumption I made [above]), you meant for x > 0 to be the length of one side of a square.
I have attached the answer in the picture.
Can someone please help me with numbers 4 and 5!!!
Answer:
Area: 378.5
Perimeter: 71.4
Step-by-step explanation:
Area = 3 square + 2 semicircle
A = 3 x 10² + 2 x (3.14 x 5²)/2 = 300 + 78.5 = 378.5
perimeter = 2 square/2 + 2circle/2
P = 2 x(10 + 10) + 2 x (2 x 3.14 x 5) / 2 = 40 + 31.4 = 71.4
p=7q-3 make q the subject
Answer:
q = (P + 3) / 7
Step-by-step explanation:
Give the expression :
P=7q-3
To make q the subject
Isolate 7q by adding 3 to both sides
P + 3 = 7q + 3
P + 3 = 7q
To. Isolate q alone, multiply both sides by 1/7
(P + 3) * 1/7 = 7q * 1/7
(P + 3) / 7 = q
q = (P + 3) / 7
