Answer:
-5/4
Step-by-step explanation:
The slop is rise over run
which means we need to find the rise over run of this equation:
So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)
So, you go down 5 times which means the top of the slope is -5
Now, how many times do we need to run to get the next plot?
You need to run 4 times to the right to get the next point now we have all the things to solve the problem:
Slope=rise/run
Answer: -5/4
Hope this helps!
Ajar containing only nickels and dimes contains a total of 60 coins. The value of all the coins in the jar is $4.45. If n represents the number of nickels and d
represents the number of dimes, which of the following systems of equations can be used to represent this situation.
O A n+d=4.45
0.05n+0. 10d=60
OB. n+d=60
5n+100=4.45
OC. ned=60
0.05n+0.10d=4.45
O D. 0.05n+0.10d=60
0.05n+0.10d=4.45
Answer: A. N+D=4.45
Step-by-step explanation: We don't know how many nickels or dimes in the jar, so to represent the unknown, we put a variable, N for the nickels, and D for dimes.

What is the slope of the line that passes through the points (2, -3) and (2, 13)
Write your answer in simplest form.
Answer:
The answer is undefined
Step-by-step explanation:
The slope of the line that passes through points (2, -3) and (2, 13) is not defined.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The line that passes through points (2, -3) and (2, 13)
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Plug the values to find the slope of the line:
m = (13 + 3)/(2-2) = 16/0 = not defined
Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.

Find the value for y so that PQ is perpendicular to RS
P(6.–2). Q(-2,8). R(-1.3), S(-9.y)
-1
0
1
2.
Answer:
A. -1
Step-by-sep explanation:
If PQ is perpendicular to RS, therefore, the slope of RS would be the negative reciprocal of PQ.
Slope of PQ:
P(6,-2), Q(-2, 8)
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 -(-2)}{-2 - 6} = \frac{10}{-8} = -\frac{5}{4} [/tex]
Slope of RS:
Slope of RS is the reciprocal of the slope of PQ, since they are perpendicular.
⅘ is the reciprocal of -⁵/4. Therefore, the slope of RS = ⅘.
Use the slope formula to find the value of y in R(-4, 3), S(-9, y).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Plug in the value
[tex] \frac{4}{5} = \frac{y - 3}{-9 -(-4)} [/tex]
[tex] \frac{4}{5} = \frac{y - 3}{-5} [/tex]
Cross multiply
[tex] (4)(-5) = (y - 3)(5) [/tex]
[tex] -20 = 5y - 15 [/tex]
Add 15 to both sides
[tex] -20 + 15 = 5y - 15 + 15 [/tex]
[tex] -5 = 5y [/tex]
Divide both sides by 5
[tex] \frac{-5}{5} = \frac{5y}{5} [/tex]
[tex] -1 = y [/tex]
y = -1

Find the value of x. Then, find the measure of each labelled angle.
x=_
(7x+10)°=_
(15x+16)°=_
Answer:
x = 7deg
Step-by-step explanation:
7x + 10 + 15x + 16 = 180 (angles adjacent to each other in a //polygon are supplementary)
22x = 154
x = 7deg
This is a question on polygons and angles. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
Robert has fish, chickens, and dogs. There are 28 eyes total and 16 legs total. Also, there are twice as many fish as chickens. How many dogs are there?
Answer:
There are 2 dogs
Explaination:
If there are 28 eyes in total,
Dogs- 4 eyes
Chickens- 8 eyes
Fishes - 16 eyes
In total they have 28 eyes
if there are 16 legs,
Dogs- 8 legs
Chickens- 8 legs
Fishes- 0 legs
So,
2 Dogs
4 Chickens
8 Fishes
( the problem even said that there are twice as many fish as chickens)

Which expression is equivalent to -3(4c-2) -2c
A. -8c
B. 8a -34
C. -26a
D. 8a + 7
Answer:
-3(4c-2) -2c = -14c+6
Step-by-step explanation:
We need to find the equivalent expression for -3(4c-2) -2c.
First we open the brackets as follows :
-3(4c-2) -2c
= -12c+6-2c
=-12c-2c+6
=-14c+6
So, the equivalent expression is -14c+6.
Halla el perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm respectivamente
Answer:
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.
Step-by-step explanation:
Para empezar debes tener en cuenta que las medidas tienen que estar en la misma magnitud; por lo tanto en este caso la unidad de medida elegida a utilizar es centímetros. Por lo que el lado que mide 6,3 dm será expresado en cm. Entonces se puede aplicar la siguiente regla de tres simple: si 1 dm equivale a 10 cm, entonces 6,3 dm a cuántos cm equivale?
[tex]cm=\frac{6,3 dm*10 cm}{1 dm}[/tex]
cm=63
Entonces 6,3 dm= 63 cm
El perímetro es la distancia alrededor de una figura, mientras que el área es las unidades cuadradas dentro de una figura.
El Perímetro de un rectángulo es igual a la suma de todos sus cuatro lados. Un rectángulo siempre tiene dos pares de longitudes iguales. Entonces en este caso se obtiene:
63 cm + 63 cm + 48 cm + 48 cm= 222 cm
El área de un rectángulo es el producto de la longitud de los lados. Entonces en este caso se obtiene:
63 cm* 48 cm= 3024 cm²
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.
How many meters Penelope jogs in 3 laps
How far, in meters, will a car travel in 20 seconds at an average speed of 20 m/s?
Answer:
400 seconds
Step-by-step explanation:
To find the distance, you have to multiply. Since each second=20 meters, you have to multiply 20 x 20 because there are 20 seconds.

Step-by-step explanation:
Robert is working two summer jobs, making $10 per hour babysitting and making
$25 per hour tutoring. In a given week, he can work no more than 10 total hours and
must earn a minimum of $130. If Robert worked 4 hours tutoring, determine the
minimum number of whole hours babysitting that he must work to meet his
requirements. If there are no possible solutions, submit an empty answer.
Answer:
3 hours
Step-by-step explanation:
The equation will be
10b+25t ≤ 130 (b = hours of babysitting, t = hours of tutoring)
Plug in the 4 hours of tutoring
10b+(25 times 4) ≤ 130
= 10b+100 ≤ 130
10 times 3 = 30, which answers the question
Since 100 + 30 = 130
Therefore, the answer to the minimum amount of hours Robert has to tutor
to make a minimum of $130 is . . .

A line passes through the points (–3, –4) and (6, 2)
What is the x-intercept of this line?
please help ahhh
9514 1404 393
Answer:
(3, 0)
Step-by-step explanation:
The line through these points intersects the x-axis at x=3.
The x-intercept is (3, 0).
_____
The x-intercept can be computed from ...
x-intercept = x1 -y1(x2 -x1)/(y2 -y1)
= -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6
x-intercept = 3
__
Here, it is simple enough to plot the points and see where the line crosses the x-axis.

Find the distance from A(15,21) to the line 5x +2y=4. Round your answer to the nearest tenth
Answer:The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
