Step-by-step explanation:
Answer:
On a coordinate plane, a line goes through points (0, negative 3) and (6, 0).
Step-by-step explanation:
First, solve for two points which solve the equation and plot these points:
First Point: For
x=0
0−2y=6
−2y=6 then divide it by -2
y=(0.-3)
second point:
x−(2⋅0)=6
x−0=6
x=(6,0)

A road starts at sea level and climbs steadily, reaching an elevation of 2000 feet after 8 miles, as shown in the diagram.
8 mi
5 mi
2000 ft
Note: Figure is not drawn to scale.
What is the elevation in feet of the road 5 miles from the starting point?
A. 1000
B. 1250
C. 750
D. 1500
Answer:
I think the answer is 1500
Step-by-step explanation:
Elevation of the road at 5 miles from the starting point is 1250 ft.
Similarity of triangles: If two triangles are similar, their corresponding sides will be proportional.
Given in the question,
Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).
Since, ∠A ≅ ∠A (Reflexive property)
∠AED ≅ ∠ACB (right angles)
ΔADE ~ ΔABC (By A-A property of similarity)
In these similar triangles, corresponding sides will be proportional.
[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]
[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]
[tex]DE=\frac{5\times 2000}{8}[/tex]
[tex]=1250[/tex] miles
Therefore, elevation of the road at 5 miles from the starting point will be 1250 ft.
Option (B) will be the answer.

Two linear functions are shown. Which function has the greater initial value?
Answer:
The answer is Function A
Step-by-step explanation:
Trust me its correct
pls mark me as brainliest
Answer:
we conclude that function A has a greater initial value.
Step-by-step explanation:
As we know that the initial value is obtained by setting x=0
so
Given the function A
From function A, it is clear that at point x=0, the value of y=8
i.e.
at x=0, y=8
Given the function B
[tex]y=3x+4[/tex]
substitute the value x=0 to get the initial value of function B
[tex]y=3x+4[/tex]
[tex]y=3(0)+4[/tex]
[tex]y=0+4[/tex]
[tex]y=4[/tex]
i.e.
at x=0, y=4
Therefore, we conclude that function A has a greater initial value.
if f(x)=x/2-2 and g(x)=2x^2-2+x-3, find (f+g)(x)
Answer:
Add all the corresponding parts of each function. The degree of x determines which correspond.
2x^2 (degree 2)
x + x/2 (degree 1)
-3-2 (degree 0)
So you get
2x^2 + 3x/2 - 5

How do you write 199.4% as a decimal?
Answer:
1.994
Step-by-step explanation:
"Percent" means "per 100" or "over 100". To convert 199.4% to a decimal rewrite 199.4 percent in terms of per 100 or over 100.
199.4% = 199.4 over 100 or,
199.4%=199.4100
199.4 over 100 is the same as 199.4 divided by 100. Completing the division we get:
199.4 ÷ 100 = 1.994
Therefore, we have shown that
199.4% = 1.994
Simplified Conversion:
Remove the percent sign % and divide by 100.
199.4 ÷ 100 = 1.994
Shortcut Conversion:
Move the decimal point 2 places to the left and remove the percent sign %
199.4% becomes 1.994
Answer:
1.99400

I need to Write an explanation of how find the slope of a line given points A (1,5) B (-7,8) can someone help me please!
Answer:
finding slope
Step-by-step explanation:
So slope is the change in y over the change in x, to show (Y/X). So finding the difference or the change usually means you need to subtract which you do to the x and y values. So you subtract the y's and x's and what you get is the change.

For the equation 6 - m = 3, how many solutions are there for m?
0
1
infinite
2
Answer:
1.
Step-by-step explanation:
The only way to get 3 as an answer to (6-m) is if m were to equal 3. Think about how many numbers can you replace m with to make the statement true. For example, try putting 1 as your m and see if it works. 6-1=3 -> 5=3. as you can see, this statement isnt true. The only solution that would work to make this statement true is one number, 3. Hope this helps.
A recipe requires 7/8 stick of butter for each 1 1/4 cups of flour. Find the unit rate of sticks of butter to cups of flour.
Let R = unit rate
R = (7/8) ÷ 1_1/4
R = (7/8) ÷ (5/4)
R = (7/8) • (4/5)
R = (7/2) • (1/5)
R = 7/10

D. the correct inequality is not listed
Answer:
c
Step-by-step explanation:
Answer:
C. 6x - y < -3Step-by-step explanation:
The graphed inequality shows that:
The function is increasing, so it has a positive slope, shaded region is to the left of the dashed line, so it should have > sign after y.Above information lets us build the inequality:
y > ax + b, where a> 0Now lets verify the options:
A. 6x + y < 3 ⇒ y < -6x + 3
NoB. -6x + y < 3 ⇒ y < 6x + 3
NoC. 6x - y < - 3 ⇒ y > 6x + 3

If a sweatshirt is on sale for 35% and now costs $52,
what was the original price?
Answer:
The original price of the sweatshirt is $80.
Step-by-step explanation:
If a product is on sale for a 35% discount, then it is 65% of the original price ( because 100 - 35 = 65)
So set up a proportion,
((part)/(whole)) = ((x)/(100))
In the given information, we know that the part (the amount paid) is 52$, what we need to find is the whole. To make solving the problem easier, let's call the whole x.
((52)/(x)) = ((65)/(100))
Simplify,
52/x = 13/20
Cross multiply,
1040 = 13x
Inverse operations,
1040 = 13x
/13 /13
80 = x
So the original price of the sweatshirt is $80.
