Answers
The slope of the line is -3/4.
Here there are two points (0,7) and (4,4)
We have to find the slope of the line.
The formula for the slope is:
slope(m) = [tex](y_{2} - y_{1} ) /( x_{2} - x_{1})[/tex]
[tex](x_{1} , y_{1} )[/tex] = (0,7)
([tex]x_{2} , y_{2}[/tex]) = (4,4)
Putting the value we have,
m = (4-7)/ ( 4-0)
= -3/ 4
Therefore the slope of a line is -3/4.

Elenaspends less than $50 ond pounds of dried chili peppers and h pounds of cornhusks. Here is a graph that represents this situation.Scorn husks (pounds)4682dried chilis (pounds)
Answers
SOLUTION
3.a. From the question, we can know that chilli pepper cost $16.95 per pound and corn cost $6.49 per pound, and she has to spend less than $50 on d chilli pepper and h corn,
This means that d represents pepper and h represents the corn, So we have
[tex]\begin{gathered} (16.95\times d)+(6.49\times h)<50 \\ 16.95d+6.49h<50 \end{gathered}[/tex]Hence the inequality that represents this is
[tex]16.95d+6.49h<50[/tex]3.b. Now from the equation, we have that
[tex]\begin{gathered} 16.95d+6.49h<50 \\ so\text{ we will substitute d for 2 and h for 4} \end{gathered}[/tex]If we get less than 50, then the answer is yes. We have
[tex]\begin{gathered} 16.95d+6.49h \\ 16.95(2)+6.49(4) \\ 33.9+25.96 \\ 59.86\text{ } \end{gathered}[/tex]Hence the answer is No because based on our calculation, she will spend $59.86 which is greater than $50.
3.c. We will again substitute 1.5 for d and 3 for h into the equation and see if we get less than 50, we have
[tex]\begin{gathered} 16.95d+6.49h \\ 16.95(1.5)+6.49(3) \\ 25.425+19.47 \\ =44.895 \\ =44.90 \end{gathered}[/tex]Hence the answer is YES because based on our calculation, she will spend $44.90 which is less than $50.

A side of the triangle below has been extended to form an exterior angle of 135°. Find the value of xx.
Answers
For the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.
As given in the question,
In a given triangle,
Measure of exterior angle is equal to 135°
Exterior angle +Adjacent interior angle = 180°
⇒ 135° + Adjacent interior angle = 180°
⇒ Adjacent interior angle = 180° -135°
⇒ Adjacent interior angle = 45°
In a triangle,
Sum of opposite interior angles = Measure of exterior angle
⇒ x° + 112° = 135°
⇒ x° = 135° -112°
⇒ x° = 23°
Therefore, for the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.

Which function has the greatest y-intercept?Group of answer choicesf(x)g(x)h(x)All three functions have the same y-intercept.
Answers
Three functions are given. It is required to find the greatest y-intercept of the three functions.
To do this, find the y-intercept of each function and check which of them has the greatest value.
The given equation for f(x) is:
[tex]f(x)=-3x-5[/tex]Notice that this is a linear function in the slope-intercept form, y=mx+c.
Where m is the slope and c is the y-intercept.
Compare to the given equation; it follows that the y-intercept of f(x) is c=-5.
The y-intercept of f(x) is -5.
The graph of g(x) is given.
Recall that the y-intercept is the point where the graph of a function intersects the y axis.
Hence, the y-intercept of g(x) is -3.
The equation for h(x) is:
[tex]h(x)=2\cos\left(2x-\pi\right)+4[/tex]To find the y-intercept, substitute x=0 into the equation:
[tex]\begin{gathered} h(0)=2\cos\left(2(0)-\pi\right)+4 \\ \Rightarrow h(0)=2\cos\left(0-\pi\right)+4=2\cos(-\pi\rparen+4 \\ \Rightarrow h(0)=2(-1)+4=-2+4=2 \end{gathered}[/tex]Hence, the y-intercept of h(x) is 2.
It follows that h(x) has the greatest y-intercept.

The constant of proportionality that Busy Bee store bottles of fresh jars of honey is 12 hours.
What is the constant of proportionality?The rate at which the fresh jars of honey is stored increases with time. This means that there is a direct proportional relationship between the jars of honey stored and time.
When there is a direct proportion, the two variables move in the same direction. As time increases, the jars of honey stored increases.
The equation that is used to represent direct proportion is:
y = bx
Where:
y = dependent variable = jars of honey stored b = constant of proportionality x = independent variable = number of hours36 = b3
