Answer:
y = 1/4x-1
Step-by-step explanation:
Ok first, you need to find the slope:
0+2 = 2=1
4+4 = 8=4
Slope: 1/4
y=1/4x+b
Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.
I will use (4,0)
0=1/4 X 4 + b
0=x+b
minus x on both sides. x=1
-1=b
An equation of the line that passes through the pair of points
(- 4, - 2), (4, 0) is y + 2 = (1/4)(x + 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line that passes through the pair of points. (−4, −2), (4, 0).
We also know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (0 + 2)/(4 + 4) = 1/4.
So, the equation of a line in point-slope form is y - y₁ = m(x - x₁).
∴ y + 2 = (1/4)(x + 4).

Adrian is drawing a map to show the directions from his house to his grandmother's house. He uses a scale of 1 1/2
inches represents 12 miles. If the distance from his house to his grandmother's house is 36 miles, how long is the drawing
on the map?
The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of miles be = 12 miles
So , 12 miles on the drawing represents = 1 1/2 inches
Now , the number of miles = 36 miles
12 x 3 = 36 miles
And , 36 miles on the drawing represents = 3 x 12 miles on the drawing
Substituting the values in the equation , we get
36 miles on the drawing represents A = 3 x ( 1 1/2 )
On simplifying the equation , we get
36 miles on the drawing represents A = 4 1/2 inches
Hence , the value on the drawing is 4 1/2 inches

Solve the system of equations using elimination. How many solutions does the system have?
15j + 12k = 18
5j + 4k = 6
Responses
A. One solution, j = 3, k = 3
B. No solution
C. One solution, j = 10, k = 8
D. Infinitely many solutions
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:

3. If you buy a new car for $6,000 which depreciates at 4%/year,
what will the value be after 3 years?
Answer:
$5,308.42
Step-by-step explanation:
(see attached for reference)
recall that the formula for Depreciation
is given by
A = P ( 1 - r)^t,
where
A = final amount
P = principal amount = given as $6,000
r = depreciation rate = given as 4% = 0.04
t = time in years = given as 3,
Simply substitute these into the equation to get:
A = P ( 1 - r)^t
= 6000( 1 - 0.04) ^ 3
= 6000 (0.96)^3
= $5,308.42

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?
Answer:
The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.
Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.
Step-by-step explanation:
First let's find the area:
5x² × 12x
= 60x³
Now the perimeter:
2(5x² + 12x)
= 10x² + 24x
HELP ASAP YALL- PLS
Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.

2.y=6x+3/4
3. y=-3/4x+6
4. y=3/4x+6
Answer:
3. y=-3/4+6
Step-by-step explanation:
The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.
Answer:
y=-3/4x+6
Step-by-step explanation:
the y/intercept is (0,6) because that is the point where the line crosses the y-axis
knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4
using the slope intercept equation y=mx+b it is y= -3/4+6
it is negative because its going downward

The sides of a regular hexagon is 16ft. What is the area of the hexagon?
Answer:
665.1
Step-by-step explanation:
The formula for an area of a hexagon is [tex]\frac{3\sqrt{3}}{2}S^{2}[/tex]
the S (side) is 16 so,
[tex]\frac{3\sqrt{3}}{2}16^{2}[/tex]
=[tex]\frac{3\sqrt{3} }{2}256[/tex]
=[tex]3\sqrt{3}[/tex] × 128
= [tex]384\sqrt{3}[/tex]
round to the nearest sq. rt. means that you have to round to the nearest tenth, or 0.1
[tex]384\sqrt{3}[/tex] is 665.10751 as a decimal
665.1 as rounded. Therefore, the area of the hexagon is 665.1 sq ft

The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?
Answer:
Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:
(1) 120x + 200y = 2150
(2) 100x + 300y = 2625
Solving the system of equations above we have 2 solutions:
x = 15/2 = $ 7.5 and y = 25/4 = $ 6.25
