The equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.
Step-by-step explanation:
We need to write an equation for the line that is parallel to the given line [tex]y=\frac{3}{4} x-9[/tex] and point (-8,-18)
The equation of required line will in in form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope m and b y-intercept for new line.
Finding slope:
When two lines are parallel, they have the same slope.
The slope of given line can be found by comparing the equation [tex]y=\frac{3}{4} x-9[/tex] with [tex]y=mx+b[/tex]
So, m = 3/4
The slope of new line will be: [tex]m=\frac{3}{4}[/tex]
Finding y-intercept:
Using slope m = 3/4 and point (-8,-18) we can find y-intercept
[tex]y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12[/tex]
So, y-intercept is b=-12
The equation of new line having m = 3/4 and b=-12 is:
[tex]y=mx+b\\y=\frac{3}{4}x-12[/tex]
So, the equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.

Step-by-step explanation:
it can't be B or C since Function A has a greater y-intercept of 2. and if you graph function A you can see that Function B has a greater rate of change
Answer:
D
Step-by-step explanation:
The rate of change for the graph is 2 so we can rule anything out that shows A has a larger rate of change. Now we look at the y intercept on the graph which is -2. The one in the function is 2 so we eliminate anything that says B has a greater y intercept this should give you the answer

*please make sure you answer all the questions please and thank you.
Answers
Answer:
x and y can be any two numbers greater than zero such that y is also greater than x
D.no more than 45
C.50 miles per hour
Step-by-step explanation:
Let the two numbers be such that x< y because we have been given y/x>1 and x/y< 1 .
Suppose we take y= 9 and x= 3 then
9/3 > 1
3>1
Also
3/9 < 1
1/3 < 1
x and y can be any two numbers greater than zero such that y is also greater than x
2. Total weight that can be carried is 3000 pounds.
The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.
The smaller machines weigh 60 pounds
The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.
3. Total distance = Speed * time
= 48 * (40/60) = 32 miles
New distance = 32+ 8= 40 miles
New time = 48 minutes
Speed = distance / time = 40/ 48/60= 50 miles per hour

Step-by-step explanation:
Angles in a Circle
We need to recall some basic concepts.
An inscribed angle is the angle formed in the interior of a circle when two secant lines intersect.
An arc of a circle is a portion of the circumference of the circle.
Theorem: Inscribed angles subtended by the same arc are equal.
In the figure provided, the points BD form an angle of 34° and the arc BD.
Similarily, arc BD also has two secants BE and DE that form the angle BED.
Thus, applying the above theorem, angle BED and 34° are subtended by the same arc, and the measure of BED is also 34°

I seem to be late but I feel like the answer is X = 12.
Step-by-step explanation:
I will start out with my expression .
First step i take is adding 3 to both sides of the expression. [tex]\sqrt{x} +4 - 3+3 = 1 + 3[/tex] . This leaves me with [tex]\sqrt{x}+4 = 4[/tex].
My second step I will need to remove the check mark thingy away from the expression. In order for me to do that, I am going to have to square both sides of the expression giving me this! [tex]\sqrt{x} +4^{2} = 4^{2} = x +4 = 16[/tex] .
Now for my final step which will be to remove 4 from both sides of my expression. X + 4 – 4 =16 – 4 = x = 12.
Leaving me with my answer of X = 12

Answers
Answer:
C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.
In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.
In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.
To solve the equations graphically, graph them and find the point where they intersect.
