The slope-intercept form of the line through (-3,1) parallel to y=-4/3x-1 is y = (-1/2)x - 2 while through (-3,-5) perpendicular to x+2y=-4 is y = 2x + 1.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given,
The slope of y = -4/3 x - 1 is -4/3.
Since parallel lines have the same slope thus,
y = (-4/3)x + c
Put (-3,1) into the above equation,
1 = (-4/3)(-3) + c
c = -3
Thus, equation will be y = (-4/3)x - 3
As per the given perpendicular line,
x+2y=-4
y = (-1/2)x - 2
Slope = 2
Put (-3,-5) into the above equation,
-5 = 2(-3) + c
c = 1
Thus, the equation will be y = 2x + 1
Hence "The line through (-3,1) parallel to y=-4/3x-1 has a slope-intercept form of y = (-1/2)x - 2, while the line through (-3,-5) perpendicular to x+2y=-4 has a slope-intercept form of y = 2x + 1".

Solve each triangle for the missing values shown. Show all work necessary. Use exact values
3)
[tex] Cos 60°= \frac{1}{2} = \frac{Adjacent} {Hypotenuse} = \frac{y} {10} \\\\ 2y=10 \\\\ y=5 [/tex]
Now, use Pythagoras theorem to find x
[tex] x^2+y^2=10^2 \\\\ \to x^2+5^2=10^2 \\\\ \to x^2+25=100 \\\\ \to x^2 = 100-25 \\\\ \to x^2= 75 \\\\ \to x= \sqrt{75} \\\\ \bf 5 \sqrt{3} [/tex]
Similarly,
4)
[tex] Sin 45°= \frac{1}{\sqrt{2}} = \frac{Opposite} {Hypotenuse} =\frac{2 \sqrt{2}} {a} \\\\ a= 2 \sqrt{2} \times \sqrt{2} \\\\ a=4 [/tex]
Now, use Pythagoras theorem to find b
[tex] b^2+(2 \sqrt{2}) ^2=a^2 \\\\ \to b^2+8=4^2 \\\\ \to b^2=16-8 \\\\ \to b^2 = 8\\\\ \to b= \sqrt{8} \\\\ \bf b=2 \sqrt{2} [/tex]
You can solve all of them in a similar way.

6. The height distributions of two different classes at Dover Elementary School are shown below. Both groups have the same interquartile range (IQR). Dover Elementary School Class Heights Third grade Fourth grade + 46 + 47 + 48 + 49 + 50 + 51 + 52 + 53 54 '55 which class has the greater median height?
Answer:
G.fourth grade
Step-by-step explanation:
The media is the line inside the box that’s the middle
In third grade the median is 50 but in fourth grade the median is 52 so therefore your answer is fourth grade

Question 3 (5 points)
Which of the following statements must be true about parallelogram ABCD?
Answer:
<C = <A
Step-by-step explanation:
In parallelograms, opposite angles are congruent. This means that <C=<A and <B=<D. Additionally, adjacent angles are supplementary; so when added they equal 180.

Step-by-step explaintion
150, 300, 450, 600, 750
250, 500, 750
375, 750
Answer:750
Step-by-step explanation:
a) 3∕5= 60∕100= 40% (resolvido) b) 11∕4= c) 4∕20= d) 9∕5= e) 10∕200= 5∕100= 5% (resolvido) f) 8∕200= g) 30∕300=
Answer:
En cada expresión queremos obtener 100 en el denominador.
Notar que en la primer eq. tendríamos:
a) 3/5 = (20/20)*(3/5) = (20*3)/(20*5) = 60/100 = 0.6 (corresponde a 60%)
b) 11/4 = ?
Acá el denominador es 4
tenemos que encontrar un número k tal que:
k*4 = 100
k = 100/4 = 25
Entonces podemos multiplicar denominador y numerador por 25.
11/4 = (25/25)*(11/4) = (25*11)/(25*4) = 275/100 = 2.75 (corresponde a 275%)
c) 4/20
el denominador es 20, entonces tenemos que resolver:
20*k = 100
k = 100/20 = 5
multiplicamos denominador y numerador por 5:
(5/5)*(4/20) = (5*4)/(5*20) = 20/100 = 0.2 (corresponde al 20%)
d) 9/5
el denominador es 5, entonces debemos resolver:
5*k = 100
k = 100/5 = 20
Debemos multiplicar denominador y numerador por 20
(20/20)*(9/5) = (20*9)/(20*5) = 180/100 = 1.8 (corresponde a 180%)
e) 10/200 = 5/100 = 0.05 (corresponde al 5%)
f) 8/200
Se resuelve de similar forma al de arriba (que ya tenias resuelto).
Aca el denominador eso 200, entonces tenemos que tener:
200*k = 100
k = 100/200 = 1/2
Entonces multiplicamos numerador y denominador por 1/2
(1/2/1/2)*(8/200) = (8*1/2)/(200*1/2) = 4/100 = 0.04 (corresponde al 4%)
g) 30/300
aca el denominador es 300
Entonces:
300*k = 100
k = 100/300 = 1/3
Multiplicamos numerador y denominador por 1/3
(1/3/1/3)*(30/300) = (30*1/3)/(300*1/3) = 10/100 = 0.1 (corresponde al 10%)

1.) y3
Step-by-step explanation:
Evaluate y=x/7+15 when y=21
Answer:
x = 42
Step-by-step explanation:
y = x/7 + 15 ; y = 21
21 = x/7 + 15
21 - 15 = x/7
6 = x/7
x = 6 × 7
x = 42
Thus, The answer is 42

Triangle ABC is similar to triangle FED, find the measure of x. A. X = 9 B. X = 11 C. X = 110 D. X = 231
Answer:
[tex]A+B+C=130[/tex]
[tex]F+E+D=273[/tex]
Step-by-step explanation:
From the question we are told that:
Dimension of ABC
A=9
B=11
C=110
Dimension of FED
D=231
Generally the equation for the similar triangles is mathematically given by
[tex]\frac{A}{F}=\frac{B}{E}=\frac{C}{D}[/tex]
Therefore solving for F
[tex]\frac{9}{F}=\frac{110}{231}[/tex]
[tex]F=\frac{9*231}{110}[/tex]
[tex]F=18.9[/tex]
Therefore solving for E
[tex]\frac{11}{E}=\frac{110}{231}[/tex]
[tex]E=\frac{11*231}{110}[/tex]
[tex]E=23.1[/tex]
Measure of [tex]\triangle ABC[/tex]
[tex]A+B+C=130[/tex]
Measure of [tex]\triangle FED[/tex]
[tex]F+E+D=273[/tex]

In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?
Answer:
8.45 grams
Step-by-step explanation:
In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?
1 mg = 0.001 g
8450 mg = x
Cross Multiply
= 8450 × 0.001 g
= 8.45 g
Therefore, Shelly should enter 8.45 grams

Answer:
If you are round the answer, you would get 15.7 cm. If not, you would get around 16 cm.
Step-by-step explanation:
The diameter is 5 and π is 3.14. You multiply those two together to get 15.7 cm. If the teacher asks to round, you will get 16 cm.
How to solve this triangle, please help me.
Answer:
sum of angles in a triangle is 180
so 70+60+ 8x+2 = 180
132+ 8x = 180
8x = 180-132
x = 48/8
x= 6
then find the angle by substituting value of x
8x + 2
8*6 + 2
= 50°
