Write the equation of the line with the given slope and the given point. Write the equation in slope-intercept form.
y = ?
Answer:
Y=x
Step-by-step explanation:
Hope this helps you!
Answer:
y = x + 8
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of 1, and contains the point (-4, 4).
We want to write the equation of this line in slope-intercept form.
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept (hence the name).
SolvingSince we already are given the slope of the line, we can immediately plug it into the equation.
Substitute m as 1 in y=mx+b.
y = x + b
We now need to find b.
As the equation passes through (-4, 4), we can use its values to help solve for b.
Substitute -4 as x and 4 as y.
4 = -4 + b
Add 4 to both sides.
4 = -4 + b
+4 +4
_________________
8 = b
Substitute 8 as b in the equation.
y = x + 8

Answer:
15 Doughnuts

Answer:
The distance between -34 and +16 is 50
the distance between -34 and -16 is 18
Step-by-step explanation:
Answer:
[First Answer] 50
[Second Answer] 18
Step-by-step explanation:
Since these are not coordinate-points and just numbers on a number line, we can subtract the smaller number from the larger number to get our answer.
[First Answer] 16 - - 34 = ? -> 16 + 34 = 50
[Second Answer] - 16 - - 34 = ? -> - 16 + 34 = 18

The width of a triangle varies inversely with its length. if the width is 4 when the length is 12 find the width when the length is 16
Answer:
3 units
Step-by-step explanation:
If a triangles dimensions vary directly, then x (length) and y (width) are related by a constant of proportionality, k such that [tex]y=kx[/tex]. If they vary inversely, [tex]x[/tex] and [tex]y[/tex] are related such that [tex]xy = k[/tex]. Using this we find the value of k for this triangle to be [tex](4)(12) = 48[/tex]. We can apply this to our new triangle with length 16 to say that [tex]16y = 48[/tex], and [tex]y=3.[/tex]
If the idea of how these equations work confuses you, think of it this way.
Varying directly means that when x increases, so does y.
Varying inversely means that when x increases, y decreases.
The opposite is true for either relationship.

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the difference between the angles' measures?
Enter your answer as the correct number of degrees, like this: 42
HELP PLEASEEEEEE
Answer:
156°Step 1: Create an Equation Using the idea (Angle B + Angle C = 180°)
=> 14x + x = 180°
Step 2: Solve.
=> 14x + x = 180°
=> 15x = 180°
=> x = 12°
Step 3: Multiply 12 by 14.
=> 12 x 14 = 168°
Step 4: Subtract 168 by 12.
=> 168 - 12
=> 156°
Final Answer:
After working on this problem, we can conclude that the difference between Angle B and Angle C is 156°

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The coordinates from the graph:
(2, 1), (3, 1.5), (4, 2), (6, 3), and (8, 4)
Where the x-axis is the number of months and the y-axis is the length of the hair in inches.
Now,
1 inch = 2.54 cm
3 inches = 3 x 2.54 = 7.62 cm
The hair length after 6 months.
= (6, 3)
= 3 inches
= 7.62 cm
Now,
6 months = 3 inches
Multiply 8/3 on both sides.
8/3 x 6 months = 8 inches
16 months = 8 inches
Now,
From the graph, we see that,
(8, 4)
This means,
In 4 months the length of the hair is 4 inches.
8 months = 4 inches
Multiply 5 on both sides.
40 months = 20 inches
Thus,
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.
