!!! HELP ME !!!
i just need the four letter code !!!
solve each box using the answer choices on the side in the picture !
Answer:
DHGB
Step-by-step explanation:
Let's start with 1.
The equation is in standard form (ax+by=c): -4x+2y=8
we'll put it into slope intercept form.
Add 4x onto both sides
2y=4x+8
divide by 2
y=2x+4
Parallel lines have the same slope, but a different y intercept. (the line parallel to this one will have a slope of 2 but a y intercept different from +4)
Looking at the answer choices, the only choice with a slope of 2 is D (y=2x-5)
So the answer to 1 is D
Now 2.
we're given 3 points. One of the points crosses the y axis, which is the y intercept. In this case, the line crosses the point (0,3)
That means the y intercept of the line is (0,3)
here's the line so far:
y=mx+3 (m is a placeholder for the slope)
when given a graph, we can use rise/run. Starting from the point (3,2), we can move 3 spaces to the left, and one up.
In a graph, if you move to the left or downwards, it's a negative move. If you move up or to the right, it's a positive move.
Since we went 1 space up (rise) and 3 spaces to the left, (run) the slope is -1/3
So the line is y=-1/3x+3
Perpendicular lines are negative and reciprocal. If you multiply their slopes, they will equal -1. Their y intercepts don't matter at all.
So to find the slope, we can use this equation.
-1/3m=-1
multiply by -3 on both sides
m=3
Looking at the answer choices, H is the only answer with a slope of 3. So the answer to 2 is H.
Now, 3
You can do the graph method like above for 2, but I'll just calculate the slope.
We're given two points, (-1,-2) and (0,2)
the formula for slope is (y2-y1)/(x2-x1)
we can label the points.
x1=-1
y1=-2
x2=0
y2=2
now, substitute into the equation.
m=(2--2)/(0--1)
m=4/1
the slope is 4.
Now let's use point slope form, which is y-y1=m(x-x1)
once again, sub. into the equation.
y+2=4(x+1)
do distributive prop
y+2=4x+4
subtract by 2
y=4x+2
As said above, parallel lines have the same slope.
Looking at the answer options, G also has the slope of 4
so the answer to 3 is G
Finally, #4
Equation: 3x+y=1
subtract 3x from both sides
y=-3x+1
As said above, perpendicular lines have slopes that multiply to equal -1.
-3m=-1
multiply by -1/3
m=1/3
so the slope of the line will be 1/3.
Looking at the answer options, B also has a slope of 1/3.
So the answer to 4 is B
The code is DHGB
Hope this helps!

what number do we use to replace the (a) a-(-19)= -12
Answer:
-31
Step-by-step explanation:
We write the equation out
[tex]a-(-19)=-12[/tex]
Distribute the -1
[tex]a+19=-12[/tex]
Subtract the 19 on both sides
[tex]a=-31[/tex]

6. The base of a triangular field is three times its height. If the cost of cultivating the field
at 36 per hectare is? 486, find its base and height (1 hectare = 10000 m²).
Answer:
base = 519.62, height = 173.21 m
Step-by-step explanation:
Let the base and height of the triangle be represented by b and h respectively.
Thus,
b = 3h
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
For the given triangle,
area = [tex]\frac{1}{2}[/tex] x b x 3h
= [tex]\frac{3}{2}[/tex]bh
Area of the triangle = [tex]\frac{3}{2}[/tex]bh
To determine the number of hectares,
36 per hectare = 486
hectare = [tex]\frac{486}{36}[/tex]
= 13.5
numbers of hectares = 13.5
Area of the hectares = number of hectares x 10 000 m²
= 13.5 x 10 000
= 135000
Total area of the hectares = 135 000 m²
So that,
area of the hectares = area of the triangle
area of the triangle = [tex]\frac{3}{2}[/tex]bh
135 000 = [tex]\frac{3}{2}[/tex]bh
270000 = 3bh
bh = [tex]\frac{270000}{3}[/tex]
= 90000
bh = 90000
But, b = 3h
3h x h = 90000
3[tex]h^{2}[/tex] = 90000
[tex]h^{2}[/tex] = [tex]\frac{90000}{3}[/tex]
= 30000
h = [tex]\sqrt{30000}[/tex]
= 173.2051
h = 173.21 m
So that,
b = 3 x 173.2051
= 519.6153
b = 519.62
Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.

The triangles △ABC and △DEF are similar.
Which set of measurements prove that the two triangles are similar?
The two triangles are similar if the ratio of the corresponding sides are equal.
What is ratio?Ratio is a mathematical comparison of two or more quantities expressed as a fraction. A ratio can be expressed as a fraction, a decimal, or in the form of words. Ratios are used to compare items or quantities in a variety of different contexts, from mathematics and science to business and daily life. For example, a ratio of 2:1 indicates that for every two items, there is one of the same item.
This means that the ratio of side AB to side DE must be equal to the ratio of side BC to side EF, and the ratio of side AC to side DF must be equal to the ratio of the remaining sides.
For example, if side AB is 10 cm and side DE is 5 cm, then side BC must be 10 cm and side EF must be 5 cm for the two triangles to be similar. Similarly, if side AC is 8 cm and side DF is 4 cm, then the remaining sides must be 8 cm and 4 cm respectively.

It's fear has a radius of 4 inches in a cube shaped box has an edge length of 7.5 inches JD says the box has greater volume so the sphere will fit in the box is he correct
Answer:
JD is wrong.
Although, the volume of the cube shaped box V' = 421.88 in³ > volume of the sphere V = 268.1 in³, the sphere cannot fit into the box because its diameter, d = 8 in > side of cube = 7.5 in.
Step-by-step explanation:
The sphere would only fit into the cube shaped box if its diameter is less than the length of side of the cube L = 7.5 inches.
So, diameter of sphere d = 2r where r = radius of sphere = 4 inches. Thus, d = 2r = 2(4 in) = 8 in.
Since the diameter of the sphere d = 8 inches > length of side of the cube = 7.5 inches, the sphere would not fit into the box.
So, JD is wrong.
We calculate both the volume of the sphere and cube.
Volume of a sphere V = 4πr³/3 where r = radius of sphere = 4 inches
So, V = 4πr³/3
= 4π(4 in)³/3
= 4π(64) in³/3
= 256π in³/3
= 804.25 in³/3
= 268.1 in³
Volume of a cube V' = L³ where L = length of side of cube = 7.5 inches
So, V' = L³
= (7.5 in)³
= 421.88 in³
Although, the volume of the cube shaped box V' = 421.88 in³ > volume of the sphere V = 268.1 in³, the sphere cannot fit into the box because its diameter, d = 8 in > side of cube = 7.5 in.

Taylor plans to borrow $4500 from the bank to purchase a used vehicle if he borrows the money at the rate of 4% interest for two years what is the total amount we will have to pay back to the bank
Answer: $ 4860
Step-by-step explanation:
Formula : Amount = P (1+rt) , P = principal value , r= rate of interest , t= time
Given ; P= $4500 , r = 4% = 0.04 , t = 2years
Total amount we will have to pay back to the bank = [tex]4500(1+0.04\times 2)[/tex]
