Find the slope and y intercept of the graph . Please help ! Thank you
Answer:
Slope: [tex]-\frac{1}{2}[/tex]
Y-intercept: 3
Equation: [tex]y =-\frac{1}{2} x + 3[/tex]
Step-by-step explanation:
The line intercepts the y-axis at the point (0, 3).
The line appears to be rising by -1 and running by 2. This gives us the slope, [tex]-\frac{1}{2}[/tex].
We can use these two parts to put together the equation: [tex]y =-\frac{1}{2} x + 3[/tex]

11. If a motorist travels 100km in 2'/2
hours, what is his average speed in
km per hour?
The average speed in km per hour is 40 km/hour if a motorist travels 100km in 2 1/2 hours the answer is 40 km/hour.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
The complete question is:
If a motorist travels 100km in 2 1/2 hours, what is his average speed in
km per hour?
We have:
The distance; a motorist travels = 100 km
The time he takes = 2 1/2 hours
or
The time he takes = 5/2 hours
or
The time he takes = 2.5 hours
The average speed in km per hour = distance/time
The average speed in km per hour = 100/2.5
The average speed in km per hour = 40 km/hour
Thus, the average speed in km per hour is 40 km/hour if a motorist travels 100km in 2 1/2 hours the answer is 40 km/hour.

What is the value of x?
Answer:
8
Step-by-step explanation:
You have to set up a proportion for this!
Because ABC and PAQ are similar triangles (same angles and PQ || BC), you can assume that all the equivalent sides are proportional!
If you solve the proportion for x:
[tex]\frac{x}{40} =\frac{7}{35}[/tex]
x = 8

Answer:
196
Step-by-step explanation:
70/252= 3.5
56x3.5=196
The length of the smallest side of Δ DEF is 196 units.
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths.
Given that, triangles ABC and DEF are similar. the lengths of the sides of ABC are 56, 64, and 72. the length of the largest side of DEF is 252.
Largest side of Δ ABC = 72 and that of Δ DEF = 252
We know that, corresponding sides of similar triangles are in equal proportion,
Therefore, the scale factor = 252 / 72 = 3.5
The smallest side of Δ ABC = 56
Therefore, the smallest side of Δ DEF = 56 x 3.5 = 196
Hence, the length of the smallest side of Δ DEF is 196 units.

In triangle ABC, the measure of angle B is 50 degrees. Give possible values for the measures of angles A and C if ABC is a right triangle.
9514 1404 393
Answer:
A = 90°, C = 40°A = 40°, C = 90°Step-by-step explanation:
In a right triangle one angle is 90° and the other angle is the complement of the acute angle given.
Angles A and C are not specified, but we know the other two angles are 40° and 90°. The values can be assigned two ways:
A = 90°, C = 40°
A = 40°, C = 90°

Step-by-step explanation:
So we know that it has to be less than or equal to $21 because that's all she has to spend. So we can automatically rule out the equations with ≥ because that means greater than.
We can also rule out the equations that have 50 at the very end because that's just how far she wants to travel.

Answer:
Value of slope is -2 and y-intercept is 1
Step-by-step explanation:
We can see that the values in the table have a linear relationship.
A linear function is a straight line written as:
y = mx+b
Here,
m is the slope and b is the y-intercept
The slope is calculated by:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
We can take any two consecutive pairs in the table to calculate the slope.
Taking first two input-output pairs.
(x1,y1) = (-3, 7)
(x2,y2) = (-2, 5)
Putting the values
[tex]m = \frac{5-7}{-2+3}\\m= -2[/tex]
Putting the value of m in the general form
[tex]y = -2x+b[/tex]
To find the value of b, we will put any pair of input-output (x,y) in the equation
Putting the first pair
[tex]7 = -2(-3) +b\\7 = 6 + b\\b = 7-6\\b = 1[/tex]
Hence,
Value of slope is -2 and y-intercept is 1
Please help meeee I don't know this
Answer:
[tex]\boxed {m = -\frac{5}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to determine the slope of two given points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First Point: [tex](x_{1} , y_{1})[/tex]
Second Point: [tex](x_{2}, y_{2})[/tex]
-Substitute both points:
First Point: [tex](5, 11)[/tex]
Second Point: [tex](19, -1)[/tex]
[tex]m = \frac{-1 - 11}{19 - 5}[/tex]
-Solve for the slope:
[tex]m = \frac{-1 - 11}{19 - 5}[/tex]
[tex]m = \frac{-10}{14}[/tex]
[tex]\boxed {m = -\frac{5}{7}}[/tex]
Therefore, the slope is [tex]-\frac{5}{7}[/tex]

mario is taking a $2,900, 2-year loan with an APR of 5.44%. what is the montly payment for this loan? round to the nearest cent
Answer:
The monthly payment for this loan is $127.80
Step-by-step explanation:
The formula of the monthly payment is
[tex]M.P=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}[/tex]
P is the initial amount of the loanr is the rate in decimaln is the period of the timet is the time of the loan∵ Mario is taking a $2,900, 2-year loan with an APR of 5.44%
∴ P = 2,900
∴ t = 2
∵ ART means annual percent rate
∴ r = 5.44% = 5.44 ÷ 100 = 0.0544
∴ n = 12
→ Substitute all these values in the formula above
∵ M.P = [tex]\frac{2,900(\frac{0.0544}{12})}{1-(1+\frac{0.0544}{12})^{-(12)(2)}}[/tex]
→ use your calculator to find the answer
∴ M.P = 127.7992528
→ Round it to the nearest cent ⇒ 2d.p
∴ M.P = 127.80
∴ The monthly payment for this loan is $127.80
