Multiple Step Equations
Solve the multiple choice equation
What is the solution to this equation?
5(x – 4) = 3x + 4
A x = -8
(B) x = -2
C x=3
(D) x = 12
Math
Answer:
D
Step-by-step explanation:
5(x-4) = 3x + 4
5x-20 = 3x + 4
5x-3x-20= 4
2x=4 +20
2x=24
x=12
check answer by inserting 12 for x into original equation.
5(12-4) = 3(12) +4
5(8) = 36 +4
40 = 40

Does the graph represent a function? Why or why not?
Answer:
Yes
Step-by-step explanation:
The line can go through the graph and have the y- axis lines hit it once
Answer:
it does not.
Step-by-step explanation:
for a graph to represent a function, it needs to pass the vertical line test (just run a finger or pencil along the graph vertically and if you never have two points touch the vertical line, it passes). there are multiple points at x=0

I have a question on this math problem that I'm stuck on
Answer:
what's the question?..
Quinton typically walks 28 yards south on Pine Street and 45 yards east on Maple Avenue in order to get to school. How much shorter would his walk be if he took the shortcut shown below? (50PTS)
Answer:
B- 20 yards
Step-by-step explanation:
First you have to find the hypotenuse by finding the square root of 28 squares plus 45 squared which equals 53 yards. Next you have to add the two legs of the right triangle so we can subtract the shortcut length from that. So you have to do 28 plus 45 which equals 73 yards. 73 minus 53 is 20. So the answer is 20 yards.
Answer:
20

So you have to do 28 plus 45 which equals 73 yards. 73 minus 53 is 20. So the answer is 20 yards.
15 points!!
b. Determine whether hypotenuse-leg (HL) is a valid means for establishing triangle
congruence for right triangles. If it is a valid criterion, explain why.
Answer:
If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Can someone put this into vertex form?
y=x2+24x-15
Answer:
The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = hLet us use the facts above to solve the question
∵ y = x² + 24x - 15
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = 24
∵ h is the x-coordinate of the vertex point
∵ h = [tex]\frac{-b}{2a}[/tex]
→ Substitute the values of a and b to find h
∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]
∴ h = -12
→ To find k substitute y by k and x by h
∵ y = k and x = h
∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15
∴ k = -159
∴ The coordinates of the vertex point are (-12, -159)
→ Substitute the values of a, h, and k in the vertex form above
∵ y = 1(x - -12)² + (-159)
→ Remember (-)(-) = (+) and (+)(-) = (-)
∴ y = (x + 12)² - 159
∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

sure.

what is -xy x=6 y=3
Answer:
the answer is -18
Step-by-step explanation:
Put 6 in for x and 3 in for y 3 times 6 is 18 and since there is a negative in front then it is a negative answer
Answer:
Heya your answer is - 18 (minus 18)
In triangle ABC, AB measures 25 cm and AC measures 35 cm. The inequality < s < represents the possible third side length of the triangle, s, in centimeters. The inequality < p < represents the possible values for the perimeter, p, of the triangle, in centimeters.
Answer:
The inequality 10 < s < 60 represents the possible third side length of the triangle, s in centimeters.
The inequality 70 < p < 120 represents the possible values for the perimeter p, of the triangle in centimeters.
Step-by-step explanation:
Firsts one The lower number has to be the difference between the bigger number and smaller number. In this case 35 - 25 = 10 and the s < 60 has to be the sum of both numbers.
Second one. I'm assuming it's just the sum of the two numbers to the first answer, and the second number is just the second number from the previous one, but multiplied by 2. Sorry that I couldn't go into too much detail about this one
The inequality that represents the possible third side length
[tex]10cm<s<60cm[/tex]
The inequality that represents the possible values for the perimeter
[tex]70cm<P<120cm[/tex]
Given :
In triangle ABC, AB measures 25 cm and AC measures 35 cm.
For any triangle , we know that the sum of measures of two sides is greater than the third side
Let 's' be the third side length
[tex]25+35>s\\60>s\\\\Also , s+25>35\\s>35-25\\s>10\\Inequality\; is \;\\10<s<60[/tex]
Now we find the perimeter when s=10
Perimeter = sum of all the sides
[tex]s=10\\P=25+35+10=70\\s=60\\P=25+35+60=120[/tex]
[tex]70<P<120[/tex]

Step-by-step explanation:
A sink contains 16 liters of water before the drain is opened. It drains at a rate of 2 liters per minute.
Use the segment tool to plot a graph representing the liters of water in the sink over time. Plot only one segment which represents the situation from when the sink starts draining until the sink is empty.
Answer:
8
Step-by-step explanation:
16 liters divided by 2 liters a minute you get 8
also i would do a graph but there is no way of putting it up with my answer i hope this helps a little if it doesnt im sorry

Can someone help me with this please asap
Answer:
The answer is 4
Step-by-step explanation:
because all of the angles need to add up to 180 so 17 x 4 is 68 and 68 - 8 = 60 and 60 x 3 = 180 so the answer would be 4
Answer:
4
Step-by-step explanation:
Since all the sides are congruent, so is the angles and in a triangle all angles add up to 180. To find the angle of one of them divide 180 by 3 which is 60.
Then put the equation equal to 60
17x - 8 = 60
17x = 68
x = 4

The table shows the amount spent on tomatoes at three different stands at a farmer's market. Which stand sold their tomatoes at the least expensive price per pound, and what is that price? Round to the nearest cent as necessary.
Answer:
i have the same question someone pls answer
Step-by-step explanation:
Stand C sold their tomatoes at the least expensive price per pound that price is 2.70 per pound.
What is Ratio?
The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Stand Weight(lb) Cost
A 3/4 2.00
B 1 1/4 3.45
C 5 1/2 14.85
We have to determine the price of sold tomatoes at the least expensive price per pound.
the price of sold tomatoes at stand A:
⇒ 2/(3/4) = 2/0.75 = 2.67 per pound.
the price of sold tomatoes at stand B:
⇒ 3.45/(5/4) = 3.45/1.25 = 2.76 per pound.
the price of sold tomatoes at stand C:
⇒ 14.85/(11/2) = 14.85/5.5= 2.70 per pound.
Here is the least expensive price per pound at stand C.
Therefore, stand C sold their tomatoes at the least expensive price per pound that price is 2.70 per pound.
