Answer:
slope = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{5}{4}[/tex] x - 1 ← is in slope- intercept form
with slope m = [tex]\frac{5}{4}[/tex]

What is the piecewise function of h(6)
Answer:
we need more info
Step-by-step explanation:
We use piecewise functions to describe situations in which a rule or relationship changes as the input value crosses certain “boundaries.” For example, we often encounter situations in business for which the cost per piece of a certain item is discounted once the number ordered exceeds a certain value.

find a ratio that equivalent to 3 to 8
Answer:
6 to 8
Step-by-step explanation:
3 and 8 multiplied by two will give an equivalent ratio
The ratio shows how many times one value is contained in another value.
The ratios that are equivalent to 3 to 8 are:
9/24, 12/32, and 15/40.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
3:8
= 3/8
We can have many ratios that is equivalent to 3:8
9/24 = (3 x 3) / (3 x 8) = 3/8
12/32 = (4 x 3) / (4 x 8) = 3/8
15/40 = (5 x 3) / (5 x 8) = 3/8
Thus,
The ratios that are equivalent to 3 to 8 are:
9/24, 12/32, and 15/40.

Correct Option: [tex]\angle XVW[/tex] and [tex]\angle YVX[/tex] are the same size
Step-by-step explanation:
Two angles are adjacent when they have a common side, a common vertex, and don't overlap.
The image shows the following angles are adjacent:
YVZ and YVX
YVZ and YVW
YVX and XVW
Furthermore, two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The first, fourth, and fifth options are true as shown above, which discards as true the second option.
The only probable false option is that XVW and YVX are the same size. They certainly could be, but we have to evidence of that, thus this option is considered false.
Correct Option: [tex]\angle XVW[/tex] and [tex]\angle YVX[/tex] are the same size

What is x
a water balloon was thrown from the window. The height of the water balloon over time can be modeled by the function y=-16square2+160x+50
The maximum height of the water balloon : 450 m
Further explanationQuadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
f (x) = ax² + bx + c
where a, b, and c are real numbers and a ≠ 0.
The parabolic curve can be opened up or down determined from the value of a. If a is positive, the parabolic curve opens up and has a minimum value. If a is negative, the parabolic curve opens down and has a maximum value
So the maximum is if a <0 and the minimum if a> 0.
The formula for finding the coordinates of the maximum and minimum points of the quadratic function is the same.
The maximum / minimum point of the quadratic function is
[tex]\rm -\dfrac{b}{2a},-\dfrac{D}{4a}[/tex]
Where
D = b²-4ac
The function h (t) = -16x²+160x+50
so the value of a <0, then it has a maximum value
Because we are looking for maximum height, then we find the value of the y coordinate, with the formula
[tex]\rm -\dfrac{D}{4a}[/tex]
Questions we might add :
What was the maximum height of the water balloon after it was thrown?
We can also use the first derivative of the above function to find the maximum value
[tex]\tt h'=0=-32x+160\\\\-32x=-160\\\\x=5[/tex]
input to function :
[tex]\tt h=-16x^2+160x+50\\\\h=-16(5^2)+160(5)+50\\\\h=-400+800+50=\boxed{\bold{450~m}}[/tex]

I need help with #6 & #7 !!
Answer:
6 is b, 7 is c
Step-by-step explanation:
Answer:
#6 wants you to find out what answer from the 4 expressions gives you the least or smallest number. For #7, you need to follow PEMDAS in order to get the right answer.
Step-by-step explanation:
#6, the answers you get are 8, -9, -3, and 9. You need to choose the smallest number. Negative numbers are smaller than positive numbers, so you can immediately eliminate 8 and 9. You have to be careful when comparing negative numbers because the larger negative number is actually smaller than the smaller negative number since it is further away from the zero. So, negative -9 would be smaller than -3 in this case.
#7, I would divide the -720/12 first. This results in -60. Then, divide the -60 by -10. This gives you an answer of positive 6.

#6 : B
#7 : C

Enter the equation of the line in slope-intercept form. Slope is − 2/3 and (-9,5) is on the line. The equation of the line is y=?
Answer:
The equation is y = 2/3x - 1
Step-by-step explanation:
To build the equation, we know the slope is -2/3, so that is done for us already. Now we just need the y-intercept, which is -1, which is the only way to get it to cross the point (-9, 5). So, the equation would be y = 2/3x - 1, while still meeting all of the qualifications. I hope this helps, and I hope it's not right, but I do not think it is.
2.Jo A certain shade of pink is created by adding 3 cups of red paint to 7 cups of white paint. How many cups of red paint should be added to 1 cup of white paint? Explain how you know. 3/7 I know this because I did 7 divided by 3 which Was 2 ⅓ so then I did 1 times 2 ⅓ which is 2 . ⅓. What is the constant of proportionality? Explain how you know. 3/7 is the constant of proportionality.
Answer:
x = 3/7
Step-by-step explanation:
Red paint : White paint = 3 cups : 7 cups
How many cups of red paint should be added to 1 cup of white paint
Red paint : White paint = x cups : 1 cup
Equate the ratios
3 cups : 7 cups = x cups : 1 cup
3 / 7 = x / 1
Cross product
3 * 1 = 7 * x
3 = 7x
Divide both sides by 7
x = 3 / 7
Number of cups of cups of red paint that should be added to 1 cup of white paint is 3/7
I did this by representing the unknown number of cups of red paint with x and equating the two ratios

A class ordered six 8-slice pizzas. Each student ate 1 1/2 slices and no pizza was left over. How many students were there?
Answer:
There are 32 students.
Step-by-step explanation:
If there are six 8-slice pizzas, that means that there is 48 slices total. If each student ate 1 1/2 slices, you can divide 48 and 1.5, and you will get 32. That is the number of students in the class. Hope this helps!
