Answer:
0.404 . . . cm/daythe average growth per day in cmStep-by-step explanation:
The slope is the x-coefficient in the equation, 0.404.
The slope is the rate of change of the dependent variable (height) with respect to the independent variable (number of days). In this case, it is the average increase in the plant's height each day, in cm.

solve x,
[tex]\frac{3x}{2} -7 = 5[/tex]
Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
Given
[tex]\frac{3x}{2} -7 = 5[/tex]
Required
Solve for x
[tex]\frac{3x}{2} -7 = 5[/tex]
Multiply through by 2
[tex]2(\frac{3x}{2} -7) = 5 * 2[/tex]
[tex]2*\frac{3x}{2} -2 * 7 = 5 * 2[/tex]
[tex]3x - 14 = 10[/tex]
[tex]3x = 14 + 10[/tex]
[tex]3x = 24[/tex]
Solve for x

5x + 12 + x = 90
Answer:
5x +12 =90
5x +12+ 90=180
90 + 5x +12 + x = 180

Solve for x in the triangle below.
Please help me guys please
Answer:
48
Step-by-step explanation:
Given is an isosceles triangle:
[tex] \angle Y \cong \angle Z (isosceles \: \triangle \: theorem) \\
m\angle Z = m\angle Y=x\\
\therefore 84\degree + x\degree +x\degree = 180\degree \\
\therefore 84\degree + 2x\degree = 180\degree \\
\therefore 2x\degree = 180\degree - 84\degree \\
\therefore 2x\degree = 96\degree \\\\
\therefore x\degree = \frac{96\degree}{2} \\\\
\therefore x\degree = 48\degree \\
\therefore x = 48 \\

A carpenter is making a backyard deck. In the measurements, he has determined that he needs to make a support triangle with an area of 22m2. He knows that the base must be 1 less than 3 times the height. If the base is represented by 3x-1 and height equals x. Find the equation that correctly shows the area of the triangle.
Group of answer choices
1/2x(3x - 1) = 11
x(3x -1) = 11
x(3x - 1) = 22
1/2x(3x - 1) = 22
Answer:
Base=3x-1
height =x
As we know that in a triangle
[tex]{\boxed{\sf Area={\dfrac {1}{2}}\times Base \times Height }}[/tex]
Substitute the value[tex]\qquad\quad {:}\longrightarrow\sf 22={\dfrac {1}{2}}(3x-1)(x)[/tex]
[tex]\qquad\quad {:}\longrightarrow\sf x (3x-1)=44 [/tex]
[tex]\qquad\quad {:}\longrightarrow\sf 3x^2-x=44 [/tex]
Correct option is option DThe equation that correctly shows the area of the triangle is 1/2x(3x - 1) = 22. Correct option is d.
To find the equation that correctly shows the area of the triangle, we use the formula for the area of a triangle:
Area = (1/2) * base * height
Given that the base is represented by 3x - 1 and the height is x, the area of the triangle is:
Area = (1/2) * (3x - 1) * x
Now, we are given that the area of the triangle is 22m^2:
(1/2) * (3x - 1) * x = 22
To solve for x, we can multiply both sides by 2 to eliminate the fraction:
2 * (1/2) * (3x - 1) * x = 2 * 22
x * (3x - 1) = 44
Now, we have the equation that correctly shows the area of the triangle:
x(3x - 1) = 44
So, the correct answer is:
x(3x - 1) = 44

MODELING REAL LIFE The graph shows the numbers of prescriptions filled over time by a pharmacy.
a. Find the slope of the line.
The slope is ____
Answer:
Slope = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Slope of a straight line passing two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Line is passing through two points (20, 5) and (80, 20),
Therefore, slope of the line will be,
m = [tex]\frac{20-5}{80-20}[/tex]
m = [tex]\frac{1}{4}[/tex]
The slope is [tex]\frac{1}{4}[/tex].
The number of deaths of children ages 1 to 14 in 1985 compared to 1991 for 10 states was gathered. (10 points) State Number of Child Deaths in 1985 Number of Child Deaths in 1991 1 33 51 2 53 33 3 58 51 4 73 44 5 88 89 6 130 142 7 212 195 8 213 215 9 275 269 10 313 312 Part A: Determine and interpret the LSRL. (3 points) Part B: Predict the number of child deaths in 1991 for State 11 if the number in 1985 was 65. Show your work. (3 points) Part C: Calculate and interpret the residual for State 11 if the observed number of deaths in 1991 was 42. Show your work. (4 points)
Solution :
From the output of regression equation given by
Number of death of children in 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]
Now, number of death of children in the year 1991 = [tex]$-5.21226+1.003538 \times \text{ No. of child death in 1985}$[/tex]
For x = no. of deaths of children in the year 1985 = 65
So substituting in the regression equation,
No. of deaths of children in year 1991 = [tex]$-5.21226+1.003538 \times 65$[/tex]
= [tex]$60.01771$[/tex]
≈ 60
Now residual = [tex]$\text{observed y - predicted y}$[/tex]
= [tex]$42-60$[/tex]
[tex]$-18$[/tex]
Part(a): Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
Part(b):
The number of child deaths in 1991 is 60.
Part(c): The observed is -18.
Part(a):
The given data can be solved by excel as,
From the output regression equation is,
Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
Part(b):
Number of child deaths is,
[tex]1991=-5.21226+1.003538\times[/tex] number of child deaths in 1985
For x=Number of child deaths in 1985=65
Number of child deaths in 1991 is,
[tex]-5.21226+1.003538\times65=60.01771\\=60[/tex]

To make a shade of paint called jasper green, mix 4 quarts of green paint with 53 cups of black paint. Select an equation that calculates how quarts of green paint, , are mixed with a given amount of black paint, .
Answer:
g = 12b /5
Step-by-step explanation:
Given that:
Quarts of green paint = 4
Cup of black paint = 5/3
Quartz of green paint to be mixed with a given proportion of black paint.
Let proportion of black paint = b
Quartz of green paint = g
4 quartz = 5/3 cups
g quartz = b
Cross multiply :
4 * b = (5/3) * g
5/3 * g = 4b
g = 4b ÷ 5/3
g = 4b * 3/5
g = 12b /5

Answer:
y=2x-5
Step-by-step explanation:
Answer and explanation is in the picture.
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line that passes through the point (3, 1) and (1, -3) is
y = 2x - 5.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c
(3, 1) = (a, b)
(1, -3) = (c, d)
Slope:
= (d - b) / (c - a)
= (-3 - 1) / (1 - 3)
= -4 / -2
= 2
m = 2
Now,
We can choose any point and set it as (x, y) and substitute it in the equation.
(3, 1) = (x, y)
y = mx + c
1 = 2 x 3 + c
1 = 6 + c
c = 1 - 6
c = -5
Now,
m = 2
c = -5
The equation of the line that passes through the point (3, 1) and (1, -3) is
y = 2x - 5.
