Step 1: Define
Point (0, 0)
Point (5, -10)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m. Slope and gradient is the same.
Substitute in points [SF]: [tex]\displaystyle m=\frac{-10-0}{5-0}[/tex][Fraction] Subtract: [tex]\displaystyle m=\frac{-10}{5}[/tex][Fraction] Divide: [tex]\displaystyle m=-2[/tex]Answer:
Let "m" be the slope of the line passing through the point.
[tex]m = \frac{y_ 2 - y_1}{x_ 2 - x_1 } = \frac{( - 10 - 0)}{(5 - 0)} = \frac{ - 10}{5} = \boxed{- 2 }[/tex]
-2 is the gradient of the line that passes through the points (0,0) and (5,-10).
If (1/4)^2-y, =1 find the value of y
Answers
1/16 - y = 1
Then you subtract 1/16 on both sides
-y = 1 - 1/16
Then subtract 1/16 from 1
-y = 15/16
Then divide by -1 to make y positive
answer —-> y = -15/16
Esther and her 6 brothers went shopping at the mall. She shopped in 12 different stores while her brothers each shopped in 8 different stores. How many stores did Esther and her brothers shop in altogether?
Answers
Answer:
60 stores
Step-by-step explanation:
Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping
From the question, she shopped in 12 different stores
Each of her six brothers shopped in 8 different stores
That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores
The total number of stores is thus, 48 + 12 = 60 stores

What is the apparent solution to the system of equations?
y = -2 +2
y=40 +7
Graph the system of equations using the Line tool. Plot a point at the apparent solution to the system using the point tool.
Answers
Answer:
y=−x+2y=4x+7 NO
y=−x+2 YES
y=4x+7
Multiply the first equation by 4, obtaining: 4y = -4x + 8
Add the 2nd equation to this result: y = 4x + 7
--------------------
5y = 15, and y = 3
Then, using the first equation, determine x:
y = 3 = -x + 2
1 = -x, so x = -1
The solution is (-1, 3)
Answer: (-1; 3)
Step-by-step explanation:
y = -x + 2
y = 4x + 7
4x + 7 = -x + 2
4x + 7 + x - 7 = - x + 2 + x - 7
5x = - 5
x = - 1
y = 4(-1) + 7
y = 3
Intersection point: (-1; 3)

A beam bridge has a total length of 168 yards. The bridge is supported at both ends and has three additional supports in the water. What is the span between any two consecutive supports?
Answers
The answer is 6
Step-by-step explanation:
6-65
The total length of a beam bridge is 168 yards. then the span between any two consecutive supports is 23 approx.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that the total length of a beam bridge is 168 yards.
The Total number of supports on the bridge = 1 at both end + 3 additional = (1 + 3 + 1) = 5 supports
Arch lies in between two successive supports ;
Hence, the number of archs = 5
Hence, width of arch = (5 * x) = 5x meters
Width of support = 2 meters
The Total width of support : (2 * x+ 1) = 2(x + 1) meters
Hence, the total distance of bridge :
Total arch width + total support width
5x + 2(x + 1) = 168 meters
5x + 2x + 2 = 168
7x = 166
x = 23 approx
Hence, the span between any two consecutive supports is 23 approx.
