Which equation best represents the line graphed above?
Please help
Answer:
y=x+4
Step-by-step explanation:
Slope is positive and it goes up by 1 so it is just 1 and the y-intercept is 4 so it is y=x+4
If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?
Let's see what to do buddy...
____________________________
Reminder:
[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
So we need to just Multiply above equations like this :
[tex]x + y = 70[/tex]
[tex]x - y = 40[/tex]
[tex](x + y)(x - y) = 70 \times 40[/tex]
[tex] {x}^{2} - {y}^{2} = 2800 [/tex]
____________________________
And we're done.
Thanks for watching buddy good luck.

A volleyball player sets a volleyball straight up into the air. The height of the volleyball, , is modeled by this equation, where t represents the time, in seconds, after that ball was set.
The volleyball reaches its maximum height after 0.625 seconds. What is the maximum height of the volleyball?
Answer:
The maximum height of the volleyball is 12.25 feet.
Step-by-step explanation:
The height of the volleyball, h(t), is modeled by this equation, where t represents the time, in seconds, after that ball was set :
....(1)
The volleyball reaches its maximum height after 0.625 seconds.

In one version of a trail mix, there are 6 cups of peanuts mixed with 4 cups of
raisins. In another version of trail mix, there are 13.5 cups of peanuts mixed
with 9 cups of raisins.
1a. Are the ratios equivalent for the two mixes?
Yes
No
This is a required question
16. Explain how you know.
Your answer
Ratio of peanuts to raisins in the first version of a trail mix = 3:2.
Ratio of peanuts to raisins in the second version of a trail mix = 4.5:3.
Divide the ratio by 1.5.
Ratio for second mix = 3:2.
The ratios are equivalent for the two mixtures.

How many quarts of water must be added to 7 qts of a 19% saline solution to obtain a 5% saline solution?
Answer: quantity of water added = 19.6 quarts
Step-by-step explanation:
Let x= quantity of water added
Then, Quantity of saline in 7 quarts solution = 19% of 7 = 0.19 (7)=1.33 quarts [to remove % divide number by 100]
When x quarts water is added , the quantity of solution becomes = x+7
Quantity of saline in it= 5% of (x+7)= 0.05(x+7)
Now, quantity of saline remains same, so
[tex]1.33= 0.05(x+7)\\\\\Rightarrow\ 1.33x=0.05x+0.35\\\\\Rightarrow\ 1.33-0.35=0.05x\\\\\Rightarrow\ x=\dfrac{0.98}{0.05}=19.6[/tex]
Hence, quantity of water added = 19.6 quarts

What is the ratio AC: CB?
Answer:
D. 1 : 2
Step-by-step explanation:
Given:
A(-6, -2),
B(6, 7),
C(-2, 1)
Required:
Ratio of AC : CB
SOLUTION:
Find AC:
[tex] AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] A(-6, -2) = (x_1, y_1) [/tex]
[tex] C(-2, 1) = (x_2, y_2) [/tex]
[tex] AC = \sqrt{(-2 -(-6))^2 + (1 -(-2))^2} [/tex]
[tex] AC = \sqrt{(4)^2 + (3)^2} [/tex]
[tex] AC = \sqrt{16 + 9} = \sqrt{25} [/tex]
[tex] AC = 5 [/tex]
Find CB:
[tex] CB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] C(-2, 1) = (x_1, y_1) [/tex]
[tex] B(6, 7) = (x_2, y_2) [/tex]
[tex] CB = \sqrt{(6 -(-2))^2 + (7 - 1)^2} [/tex]
[tex] CB = \sqrt{(8)^2 + (6)^2} [/tex]
[tex] CB = \sqrt{64 + 36} = \sqrt{100} [/tex]
[tex] CB = 10 [/tex]
Find AC : CB
AC : CB = 5 : 10 = 1 : 2

A cyclist rode at a constant speed of 21mph for 3 hours. Then she decreased her rate of speed to 17 mph for 4 hours. How far fid they cyclist ride in 7 hour
Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.
What is the speed?
The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here given that,
A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.
[tex]21[/tex] x [tex]3[/tex] [tex]=63 + 17 (4)[/tex]
[tex]= 131[/tex] miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.
