Answer:
Only: C. The lines are perpendicular.Step-by-step explanation:
4x - 2y = 6 x + 2y = 14
- 2y = - 4x + 6 2y = - x + 14
y = 2x - 3 y = - ¹/₂x + 7
A.
y-intecept: (0, -3) (0, 7)
The lines don't share the same y-intercept
B.
x=1 ⇒ y = 2(1)-3 = -1 and y = -¹/₂(1) + 7 = 6¹/₂ ≠ -1
the line x+2y=14 doesn't go through point (1,−1) so the lines couldn't intersect at point (1,−1)
Slope: m₁ = 2 m₂ = -¹/₂
C.
m₁· m₂ = 2·(-¹/₂) = -1
The lines are perpendicular.
D.
m₁ ≠ m₂ The lines are not parallel
please help important!!!!!!!!!!!!!
Answer:
the answer is B!! hopefully this helps
what is the slope of (2,-2) and (5, -6) ?
Answer:
-4/3
Step-by-step explanation:
Answer:
m = - 4 /3
Step-by-step explanation:
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m = y2 - y1 / x2 - x1
m =( -6) - (-2)/ 5 - 2
m = -6 plus 2 / 3 I put plus because negative times negative is plus
m = -4 / 3 negative 6 plus 2 is -4
To find y2, y1, x2 and x1 you have look on the two points that they gave you.
(2, -2), The x1 is 2 and y1 is -2
(5,-6), The x2 is 5 and y2 is -6
At the beginning of the year, John had $40 in savings and saved an additional $13 each week thereafter. Isaac started the year with $80 and saved $9 every week. Let J represent the amount of money John has saved tt weeks after the beginning of the year and let I represent the amount of money Isaac has saved t weeks after the beginning of the year. Write an equation for each situation, in terms of t, and determine the number of weeks after the beginning of the year until John and Isaac have the same amount of money saved.

You spent $88 buying two shirts at Macy's along with two scarves that cost $30.00. If s is the cost of the shirt, and the equation representing the purchase is: 2s + 30.00 = 88. What is the cost of the shirt?
Answer:
58
Step-by-step explanation:
Answer:
s = 29
Step-by-step explanation:
Let's solve your equation step-by-step.
2s+30=88
Step 1: Subtract 30 from both sides.
2s+30−30=88−30
2s=58
Step 2: Divide both sides by 2.
2s

=
58

What are the coordinates of point P on the directed line segment from A (-5, -4) to B(5, 1) that partitions the segment into a ratio of 3 to 2?
(1 point)
(11,4)
0 (-1, -2)
O (1, -1)
O 0,- 3)
Answer:
Option (3)
Step-by-step explanation:
Coordinates of a point (h, k) which divides a line with ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the ratio of m : n are,
h = [tex]\frac{mx_2+nx_1}{m+n}[/tex]
k = [tex]\frac{my_2+ny_1}{m+n}[/tex]
If the ends of line AB are A(-5, -4) and B(5, 1) and a point (h, k) divides this line into two parts in the ratio of 3 : 2
h = [tex]\frac{3\times (5)+2(-5)}{3+2}[/tex]
h = 1
k = [tex]\frac{3(1)+2(-4)}{3+2}[/tex]
k = -1
Therefore, coordinates of the point (h, k) are (1, -1).
Option (3) will be the answer.

Alex has 64 cubes with dimensions in feet (ft), like the one shown. He uses all the cubes to fill a box shaped like a larger rectangular prism. There are no gaps between the cubes. Part B: If there are 64 of these cubes in the larger prism, then what is the volume, in cubic feet, of the larger rectangular prism?
Answer:
The volume, in cubic feet, of the larger rectangular prism is 64 cubic feet
Step-by-step explanation:
Length of small cube =[tex]\frac{1}{2} ft[/tex]
Volume of each cube = Side^3
Volume of each cube =[tex](\frac{1}{2})^3[/tex]
=[tex]\frac{1}{8} ft^3[/tex]
Volume of 64 cubes = [tex]64 \times \frac{1}{8}[/tex]
Volume of 64 cubes [tex]= 8 ft^3[/tex]
We are given that He uses all the cubes to fill a box shaped like a larger rectangular prism.
So, Volume of 64 cubes = Volume of rectangular prism
So, If there are 64 of these cubes in the larger prism, then the volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

write an equation that is parallel to the equation (-3,-5) and (1,7) and goes through the point (2,4)
You didn't give an original equation, just the two points so I'm just going to go ahead and assume that b = 0, but in reality, it doesn't really matter what it equals I think.
Slope intercept form:
First, we find the slope, so we do y1-y2/x1-x2 which is 3. So then we do y=mx+b so 4=3(2)+b. Then we do 4=6+b. So, b = -2.
So the equation is y=3x-2
Find the slope which we already know. Plug into y-y1=m(x-x1).
y-4=3(x-2)
y-4=3x+6
Brian, Chris, and Damien took a math test that had 20 questions. The number of questions Brian got right is 14 more than the number of questions Chris got right. Damien correctly answered 2 less than the number of questions Chris answered correctly. If Brian and Damien have the same score, which statement is true?
Answer:
C. Brian and Damien both answered 2 more questions correctly than Chris did.
Step-by-step explanation:
A. Brian and Damien both answered 2 fewer questions correctly than Chris did.
B. Brian and Damien both answered 4 more questions correctly than Chris did.
C. Brian and Damien both answered 2 more questions correctly than Chris did.
D. Brian and Damien both answered 4 fewer questions correctly than Chris did.
Let
B = number of questions Brian got right
C = number of questions Chris got right
D = number of questions Damien got right
The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right.
B = 14 + (1/4) * C
Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly.
D = (5/4) C - 2
If Brian and Damien have the same score,
14 + (1/4) * C = (5/4) C - 2
14 + 1/4C = 5/4C - 2
14 + 2 = 5/4C - 1/4C
16 = 5C-C/4
16 = 4/4C
C = 16
B = 14 + (1/4) * C
= 14 + 1/4*16
= 14 + 4
= 18
D = (5/4) C - 2
= 5/4*16 - 2
= 5*4 - 2
= 20 - 2
= 18
