What is an equation of the line that passes through the point (-5,2) and is parallel
to the line 4x - 5y = 5?
Answer:
Step-by-step explanation:
first change the equation so it just equals y
-5y = 5 -4x
y = 4/5x -1
since this new equation has to be parallel to the previous line, the slopes are the same
y = 4/5x + b
now we have to make sure the new equation passes through (-5,2) so we plug in -5 for x and 2 for y
2 = 4/5(-5) + b
2 = -4 + b
b = 6
so the final equation is
y = 4/5x +6
The equation of the line that passes through the point (-5,2) and is parallel to the line 4x - 5y = 5 is 5y - 4x = 30
The equation of a line in point-slope form is expressed as:
[tex]y-y_0=m(x-x_0)[/tex]
m is the slope of the line
(x0, y0) is any point on the line
Given the equation 4x - 5y = 5.
Rewrite in standard form:
-5y = -4x + 5
y = 4/5 x - 1
The slope of the line passing through the given equation is 4/5
Substitute the slope and the point into the equation:
[tex]y-2=4/5(x+5)\\5(y-2)=4(x+5)\\5y-10=4x+20\\5y-4x=20+10\\5y-4x=30[/tex]
Hence the equation of the line that passes through the point (-5,2) and is parallel to the line 4x - 5y = 5 is 5y - 4x = 30

Identify the interval(s) on which the function y = -x2 + 5x + 14 is positive.
A.) X < -2 and x > 7
B.) X > 2 and x < -7
C.) -7 < x < 2
D.) -2 < x < 7
Given:
[tex]y=-x^2+5x+14[/tex]
To find:
The interval on which the given function is positive.
Solution:
We have,
[tex]y=-x^2+5x+14[/tex]
Splitting the middle term, we get
[tex]y=-x^2+7x-2x+14[/tex]
[tex]y=-x(x-7)-2(x-7)[/tex]
[tex]y=(x-7)(-x-2)[/tex]
[tex]y=-(x-7)(x+2)[/tex]
Using zero product property, we get
[tex]x-7=0\text{ and }x+2=0[/tex]
[tex]x=7\text{ and }x=-2[/tex]
-2 and 7 divide the number line is three interval.
Interval Signs of [tex]y=-(x-7)(x+2)[/tex] Result
(-∞,-2) (-)(-)(-) Negative
(-2,7) (-)(-)(+) Positive
(7,∞) (-)(+)(+) Negative
So, the function is positive for the interval (-2,7), i.e., -2 < x < 7.
Therefore, the correct option is D.

Answer:
15/8 or 1 7/8

3*5=15 which gets you 15/8. Since 8 is a whole subtract 15 - 8 = 7 so your mixed number would be 1 7/8
Calculate the area of a circle with the radius of 2cm. Pie=3
Answer:
12
Step-by-step explanation:
The formula to find the area of a circle is:
[tex]\pi[/tex][tex]r^{2}[/tex]
Where "r" is the radius of the circle.
In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.
The equation will be:
3 * 2^2
Simplify, remember the order of operations:
3 * 4
12
Answer:
12.56 cm
Step-by-step explanation:
Area of a circle is A=3.14 r to the second power.
so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56
i don't know what pie=3 means but this is my answer from the best of my ability.
Draw a diagram to represent each of these situations. Then write an addition expression that represents the final temperature.
The temperature was 80 ℉ in Arizona and then fell 20 ℉ during the night.
The temperature was -13 ℉ in Minneapolis and then rose 9 ℉ in the morning.
The temperature was -5 ℉ in Denver and then fell 8 ℉ by the morning.
Answer:
1) 80+(-20)
2) -13+9
3) -5+(8)
I don't quite know how to explain
Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).
at a basketball game at team made 58 successful shots they were a combination of one and two point shots the team scored 98 points in all right and solve a system of equations to find out the number of each type of shot
Answer:
There were 18 1 point goals and 40 2 point goals
Step-by-step explanation:
Let the number of one point shots be x and the number of two point shots be y
Total number of shot is 58
x + y = 58 ••••(i)
Then;
Total of 1 point is 1 * x = x
Total of 2 points is 2 * y = 2y
x + 2y = 98 ••••••(ii)
x = 98-2y
Put this in 1
98-2y + y = 58
-y = 58-98
y = 40
x = 58-40
x = 18
Water flows down the Mississippi river at about 1.2 miles per hour. The relationship between hours and miles the water has traveled is... Discrete or continuous
Answer:
Continuous
Step-by-step explanation:
Given
[tex]Rate = 1.2\ miles/hour[/tex]
Required
Determine if this relationship is discrete or continuous
Numbers in their whole form (i.e. 1,2,3.....) represent discrete values while others with decimals (such as 0.2,0.9, 1.2...) represent continuous values
From the above analysis, we can see that 1.2 fall in the category of continuous values.
Hence, the relationship between both parameters is continuous

32-ounce containers for $10.97. Which is the better buy? (Example 1)
Answer:
the second one

what is y=-4/3x-4 in standard form
Answer:
4x + 3y = - 12
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - [tex]\frac{4}{3}[/tex] x - 4 ( multiply through by 3 to clear the fraction )
3y = - 4x - 12 ( add 4x to both sides )
4x + 3y = - 12 ← in standard form
