Answer:
slope is 10x
Y - intercept is 7
Step-by-step explanation:
The equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have a line that has a slope of 10 and passes through the point (0, 7).
Assume the equation of the line to be -
y = 10x + c {since m = 10}
For the point (0, 7), we can write -
7 = 10 x 0 + c
c = 7
So, the equation of the line will be -
y = 10x + 7
Therefore, the equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7

What is the explanatory variable?
A) age of patient
B) gender of patient
C) amount of symptom relief
D) concentration of active ingredient
Answer:
D
Step-by-step explanation:
The required explanatory variable is concentration of active ingredients. Option D is correct.
Given that,
From the paragraph, "Medical researchers studying a medication in male and female patients 20 to 29 years old noticed that, up to a certain amount, a larger concentration of an active ingredient lead to greater levels of symptom relief." it is to be determined which is an explanatory variable.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A) age of patient = Not explanatory
B) gender of the patient = Not explanatory
C) amount of symptom relief = Not explanatory
D) concentration of active ingredient = Explanatory
Thus, the required explanatory variable is the concentration of active ingredients. Option D is correct.

A person has a rectangular board 12 inches by 16 inches around what she wants to put a uniform border of shells if she hasn't of shells were border whose area is 128 square in determine the width of the Border
Answer:
2 inches
Step-by-step explanation:
Given that:
Dimensions of rectangular board = 12 inches by 16 inches
Area of uniform border around the rectangular board = 128 square inches
To find:
Width of the border = ?
Solution:
Let the width of the uniform border = [tex]x[/tex] inches
Now, there are two rectangular shapes after the addition of border.
One rectangle with the border, one without the board.
Area of border can be found by subtracting the area of board from the area of rectangle with the board.
Dimensions of the rectangle with the border = (12+2[tex]x[/tex]) inches by (16+2[tex]x[/tex]) inches
Area of rectangle = Length [tex]\times[/tex] Width
So, area of border = ((12+2[tex]x[/tex]) [tex]\times[/tex] (16+2[tex]x[/tex])) - 16 [tex]\times[/tex] 12 = 128 square inches
[tex]\Rightarrow 4x^2+56x+192-192=128\\\Rightarrow 4x^2+56x-128=0\\\Rightarrow x^2+14x-32=0\\\Rightarrow (x+16)(x-2)=0\\\Rightarrow x = 2, -16[/tex]
Width can not be negative, so possible value of width = 2 inches
If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?
A horizontal line. A line extends from the line to form a 90 degree angle. Another line cuts through the 2 lines to form angles 1 and 2, which total 90 degrees.
32 degrees
38 degrees

A. 40
B. 35
C. 20
Answer:
C
Step-by-step explanation:
im pretty sure it this because it would make 180 degrees ;-;
Answer:
20 degrees
Step-by-step explanation:
angles on a straight line/ straight line angles/ supplementary angles = 180 degrees
angle 1 + angle 2 = 180 degrees
160 + angle 2 = 180
angle 2 = 180 = 160
angle 2 = 20 degrees

In Triangle JKL, ∠J is congruent to ∠L. Triangle J K L is shown. Ray L K extends beyond point K to form an exterior angle that is labeled sixty-seven and eight tenths degrees. What is the measure of ∠L? Enter the correct answer in the box.
Answer:
m<L = [tex]33.9^{o}[/tex]
Step-by-step explanation:
Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.
The exterior angle formed = [tex]67.8^{0}[/tex]
But,
<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)
Let <J ≅ <L be represented by a, so that;
a + a = [tex]67.8^{0}[/tex]
2a = [tex]67.8^{0}[/tex]
a = [tex]\frac{67.8^{o} }{2}[/tex]
= [tex]33.9^{o}[/tex]
The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =
Thus,
m<J ≅ m<L = [tex]33.9^{o}[/tex]

t÷5/12= -3/10
Thank you if you help :)
Answer:
t = -1/8.
Step-by-step explanation:
t / 5/12 = -3/10 Invert the 5/12 and multiply:
12t / 5 = -3/10
Cross multiply:
12t * 10 = 5 * -3
120t = -15
t = -15/120 = -1/8.
