Step-by-step explanation:
if it is correct plz plz mark as brainliest
thank you

Answer:
y = 2x-6
Step-by-step explanation:
Slope intercept form:
y = mx+b
m = slope
In this case the slope is 2/1 or 2.b = The point where the line crosses the y-axis
In this case -6 is the exact point the line crosses the y-axisSo if you put it all together you get the answer of:
y = 2x-6
I hope this helped!

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = -16x^2 + 232x + 134
Answer:
15.06 seconds.
Step-by-step explanation:
Hit Ground→Height=0
−16x^2 +232x + 134=0
Choose the graph of the inequality x> -2
Choose 1 answer. HELPPPP
Step-by-step explanation:
step 1. x > -2 means numbers greater than -2 but not including -2.
step 2. you graph a single variable on a number line.
step 3. the graph would include an open circle above -2 (not equal to -2)
step 4. the line would go right of the open circle (greater than) and have an arrow at the end.
step 5. the answer is b.

Step-by-step explanation:
Ira bought a t-shirt that was discounted 50%. He used a coupon for 50% off at the cash register. Why was he charged $6.50 instead of $0?
50% off makes the new price half of the original, then another 50 % would be half off the discounted price, so they actually end up paying 25 % of the original price:
50 % x 50 % = 25 %
Answer:
she was charged for 50% of the 50% off
Step-by-step explanation:
Lets say the original price was 100$ The store discounted it by 50% so it is now 50$ but the coupon take 50% off of that 50 so it would be 25$
Which graph represents the function f(x) = 4|x|?
Answer:
The 2nd one
Step-by-step explanation:
It is a compression, because you are multiplying by a whole number greater than 1, therefor the line will look thinner
Can you explain to me how to solve this?

can anyone give me the formula to this or how to solve it? thanks
The width is 3.
A rectangular prism is 3d. This means that there are three dimensions being multiplied by each other to obtain the overall volume. We can use the equation V = lwh to solve this equation, with V being volume, and the following, length, width, height. Substituting in the values (and changing the mixed numbers to improper fractions for simplicity):
1035/4 = (15/2)(23/2)(w)
w = (1035/4)(2/15)(2/23)

sketch the graph of each function. Then State the domain, range and increasing, decreasing intervals. Part 3.
Answer:
19) Domain: - ∞ < x < ∞ 20) Domain: - ∞ < x < ∞
Range: - ∞ < y < ∞ Range: - ∞ < y < ∞
Increases throughout Decreases throughout
Step-by-step explanation:
Given the parent function " y = ∛x" we know that the first graph should have a vertical shift down 2 units, and a horizontal shift 4 units to the right. There is no vertical stretch since there is no coefficient. (Check first graph)
Domain: - ∞ < x < ∞
Range: - ∞ < y < ∞
Increases throughout
______________________________
For the second graph there should be a vertical shift down three units, a horizontal shift 1 unit to the left, and a vertical stretch by a factor of - 1. (Check second graph)
Domain: - ∞ < x < ∞
Range: - ∞ < y < ∞
Decreases throughout

Answer:
(c) [tex]h(3) = 1[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Find h(3)
The formula to use in solving this is:
[tex]y = h(x)[/tex]
Substitute 3 for x
[tex]y = h(3)[/tex]
From the attached graph, the value od x = 3 points to the value of y = 1.
So, we have:
[tex]y = 1[/tex]

Which set of values for x makes the inequality 12−x<7 true
Answer:
[tex]\{x:x>5\}[/tex]
Step-by-step explanation:
Given
[tex]12 - x < 7[/tex]
Required
Values of x that make it true
First: solve the inequality.
[tex]12 - x < 7[/tex]
Collect Like Terms
[tex]- x < 7-12[/tex]
[tex]- x < -5[/tex]
Multiply both sides by -1
[tex]-1 * - x < -5 * -1[/tex]
[tex]x > 5[/tex] --- The inequality changes when multiplied by a negative value
So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)
Hence, the set is:
[tex]\{x:x>5\}[/tex]

7 1/3 : 2 4/9= what does it equal?
Answer:
3/1 or 3
Step-by-step explanation:
7 1/3 = 7x3 + 1/3 =21 + 1/3 =22/3
7x3/3 = 21/3
-------------------------------------------------
2 4/9 2x9 + 4/9 = 18 + 4 /9= 22/9
2x9/9 = 18/9
Divide: 22/3 : 22/9 =22/3 x9/22 =
22/3 x 9/22 = 198/66 66/66 x 3/1 = 3
PLS HELP TIMED QUESTION!!!
A quantity with an initial value of 9800 decays exponentially at a rate such that the quantity cuts in half every 6 days. What is the value of the quantity after 138 hours, to the nearest hundredth?
Answer:
About 5043.58
Step-by-step explanation:
The standard form for an exponential decay after t time is:
[tex]\displaystyle f(t)=a(r)^{t/d}[/tex]
Where a is the initial value, r is the rate decay, t is the time that has passed, and d is the amount of time it takes for 1 cycle.
The initial value is 9800. So a = 9800.
The quantity cuts in half. So, r = 1/2.
And it cuts in half every 6 days. For this question, we will convert this to hours. 6 days = 144 hours. So, we can let d = 144, where t will be in hours.
Therefore, our function is:
[tex]\displaystyle f(t)=9800\Big(\frac{1}{2}\Big)^{t/144}[/tex]
Where t is the amount of time that has passed, in hours.
Then the quantity left after 138 hours will be:
[tex]\displaystyle f(138)=9800\Big(\frac{1}{2}\Big)^{138/144}\approx 5043.58[/tex]

Find the curved surface area of a cylinder if it's base circumference is 36 cm and it's height is 4 cm
Answer:
CSA of a cylinder = 144cm²
Step-by-step explanation:
Given the following data;
Base circumference = 36cm
Height = 4cm
To find the curved surface area (CSA) of the cylinder;
CSA of a cylinder = 2πr * h
But 2πr = 36cm
Substituting the values into the equation, we have;
CSA of a cylinder = 36 * 4
CSA of a cylinder = 144cm²
Geometry A. In unit 2, you learned three different criteria for proving triangle congruence: ASA, SAS, and SSS. Can you give me the summarize each of them for me? 100 POINTS
Answer:
we use the ASA when a triangle is conguerent by angle,side,angle.
SAS se when atriangle is conguerent by side,angle,side
sss when the triangle is conguerent by side,side,side
Answer:
ASA- The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
SAS- is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent.
SSS- If two triangles are congruent it means that all corresponding angle pairs and all corresponding sides are congruent. The SSS criterion for triangle congruence states that if two triangles have three pairs of congruent sides, then the triangles are congruent
