Answers
Answer:
y=3, 0; 9x-3y=18, 3; line through (5, 7) and (5, – 8), undefined; the line through ( – 4, – 1) and (-1,–7), -2;
Step-by-step explanation:
y=3 is a horizontal line so the slope is 0
9x-3y=18 can be written as 3y=9x-18 or y=3x-6 so the slope is 3
the line through (5,7) and (5,-8) is a vertical line since the x value didnt change between the two points so the slope is undefined
we have to find the slope of the line through ( – 4, – 1) and (-1,–7). to do this use the formula (y_2-y_1)/(x_2-x_1)=(-7-(-1))/(-1-(-4))=(-7+1)/(-1+4)=-6/3=-2 so the slope is -2

The area of the rectangle is 68 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answers
let "L" represent the length of the rectangle
let "W" represent the width of the rectangle
Area of the rectangle = LW
68= LW --------eqn 1
Area of a square = L/2 ×L/2
34= L^2/4
136=L^2
L= 11.67
From eqn 1 , W=68/L
W=68/11.6619
W=5.83
If two vectors are perpendicular then what is the condition
Answers
Answer:
If two vectors are perpendicular, then their dot-product is equal to zero. The cross-product of two vectors is defined to be A×B = (a2_b3 - a3_b2, a3_b1 - a1_b3, a1_b2 - a2*b1). The cross product of two non-parallel vectors is a vector that is perpendicular to both of them.

Maggie studied for 2/5 of an

Maggie study?
Answers
Answer: 3/20
Concept:
When encountering questions that ask for [how much longer A comparing to B], the basic operation would be the value of A subtracted by the value of B.
Solve:
Given information
Maggie study time = 2/5 hours
Julie study time = 1/4 hours
Given expression deducted from the concept
Maggie (study time) - Julie (study time)
Substitute values into the expression

Find the denominators' Least Common Multiple (LCM)
First five multiples of 5: 5, 10, 15, 20, 25
First five multiples of 4: 4, 8, 12, 16, 20
Since [20] is the first term that appears in both multiples, it would be the LCM of 4 and 5
Convert the fractions to common denominator
2/5 = (2 × 4) / (5 × 4) = 8 / 20
1/4 = (1 × 5) / (4 × 5) = 5 / 20
Simplify by subtraction
=8/20 - 5/20
=(8 - 5) / 20

valentines was 1 more than twice the number of

valentines was 2 less than the number of
35-cent ones. If he spent $4.20 all together,
how many valentines of each kind did he buy?
Answers
9514 1404 393
Answer:
20-cent: 935-cent: 450-cent: 2Step-by-step explanation:
Let x, y, z represent the numbers of 20-cent, 35-cent, and 50-cent valentines. Then the given relations can be written as ...
x = 1 +2y
z = -2 +y
0.20x +0.35y +0.50z = 4.20
__
Using the first two equations to substitute for x and y in the third equation, we get ...
0.20(1 +2y) +0.35y +0.50(-2 +y) = 4.20
1.25y -0.80 = 4.20 . . . . . simplify
1.25y = 5.00 . . . . . . . . . . add 0.80
y = 4 . . . . . . . . . . . . . . . divide by 1.25
x = 1 +2(4) = 9
z = -2 +4 = 2
Romeo bought 9 20-cent, 4 35-cent, and 2 50-cent valentines.

X=67°,Z=113°,Y=0°
Step-by-step explanation:
2.1=
X+113°=180°(being straight angle)
Or, X=180°-113°
Or,X=67° answer
Now,
Z=113°(being alternative angle)
Again,Y+Z+X=180°(being co-interior angle)
Or, Y+113°+67°=180°
Or,Y+180°=180°
Or,Y=180°-180°
=Y=0° answer
