Answer:
[tex]y=\dfrac{5}{4}x+1[/tex]
Step-by-step explanation:
Slope intercept form a equation of a line is given by the following formula:
Slope intercept form:
[tex]y=mx+c[/tex]
Given that, a point is (-4,-4)
i.e.
[tex]x=-4,\\y=-4[/tex]
Slope, [tex]m =\frac{5}{4}[/tex]
Putting the given values in the Slope intercept form equation:
[tex]-4=-4\times \dfrac{5}{4}+c\\\Rightarrow -4=-5+c\\\Rightarrow c =1[/tex]
Putting the value of [tex]c[/tex] and [tex]m[/tex] in the slope intercept form:
[tex]y=\dfrac{5}{4}x+1[/tex]

Let u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩. Kelcy incorrectly determined 3u – 5(v + w) to be ⟨32, –26⟩. Review her steps as shown.
3u – 5(v + w)
3⟨9, –2⟩ – 5[⟨–4, 3⟩ + ⟨5, 1⟩]
⟨27, –6⟩ – 5[⟨–1, 4⟩]
⟨27, –6⟩ + ⟨5, –20⟩
⟨32, –26⟩
What mistake did Kelcy make?
She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.
She did not correctly distribute 3 to both components of u.
She should have distributed –5 to both v and w before adding.
She should have subtracted ⟨27, –6⟩ and ⟨5, –20⟩, rather than adding.
Answer:
A
Step-by-step explanation:
-4 +5 is 1 not -1 lol
The incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.
How to add two vectors?Suppose that two vectors are given as:
[tex]x = \: < a,b > \\y= \: < c,d >[/tex]
Then, their addition is given as:
[tex]x + y = \: < a +c , b + d >[/tex]
For this case, we can see that when Kelcy added <-4,3 > and <5,1>, she didn't add -4 and 5 correctly, as it results in +1, and not -1,
Thus, <-4,3> + <5,1> = <1,4>
Thus, wrong addition caused error in the solution.
Thus, the incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.

Answer:
17.5
Step-by-step explanation:
175% is written as 175/100. If you move the decimal at the end over twice you get 1.75/1 which is just 1.75. You then multiple 10 by 1.75 and you get 17.5

If the product (2x + 3)(x + k) is 2x2 + 13x + 15, what is the value of k?
Given:
The product [tex](2x + 3)(x + k)[/tex] is [tex]2x^2+13x+15[/tex].
To find:
The value of k.
Solution:
According to the question,
[tex](2x + 3)(x + k)=2x^2+13x+15[/tex]
Using distributive property, we get
[tex]2x^2+2xk+3x+3k=2x^2+13x+15[/tex]
[tex]2x^2+(2k+3)x+3k=2x^2+13x+15[/tex]
On comparing both sides, we get
[tex]3k=15\text{ and }2k+3=13[/tex]
[tex]k=\dfrac{15}{3}\text{ and }2k=13-3[/tex]
[tex]k=5\text{ and }2k=10[/tex]
[tex]k=5\text{ and }k=5[/tex]
Both value of k are same, i.e., 5.
Therefore, the value of k is 5.
Tyler bought 3 calculators and 7 pens for $67.80. Barbra bought 6 calculators and 2 pens for $92.40. How much does each pen cost?
Answer:
Each pen costs $3.60 (Each calculator costs $14.20).
Step-by-step explanation:
Let c represent calculator
Let p represent pen
3c + 7p = 67.8
6c + 2p = 92.4
Step 1: Solve 3c + 7p = 67.8 for c:
3c + 7p = 67.8
3c + 7p + −7p = 67.8 + −7p (Add -7p to both sides)
3c = −7p + 67.8
3c/3 = −7p + 67.8/3 (Divide both sides by 3)
c = −7/3p + 22.6
Step 2: Substitute −7/3p + 22.6 for c in 6c + 2p = 92.4:
6c+2p=92.4
6(−7/3p + 22.6) + 2p = 92.4
−12p + 135.6 = 92.4 (Simplify both sides of the equation)
−12p + 135.6 + −135.6 = 92.4 + −135.6 (Add -135.6 to both sides)
−12p = −43.2
−12p/−12 = −43.2/−12 (Divide both sides by -12)
p = 3.6
Step 3: Substitute 3.6 for p in c = −7/3p + 22.6:
c = −7/3p + 22.6
c= −7/3(3.6) + 22.6
c = 14.2 (Simplify both sides of the equation)
Answer:
c = 14.2 and p = 3.6

En una clase, 1/3 de los estudiantes eligieron estudiar español como segundo lenguaje vivo. 1/9 eligió italiano, el resto eligió alemán. Qué fracción de los estudiantes de la clase eligieron estudiar alemán? Si hay 15 estudiantes estudiar alemán, ¿cuántos estudiantes no estudian alemán?
Answer:
5/9
12
Step-by-step explanation:
La clase entera es 1.
1/3 estudian español.
1/9 estudian italiano.
1 - 1/3 - 1/9 estudian alemán.
1 - 1/3 - 1/9 = 9/9 - 3/9 - 1/9 = 5/9
5/9 de los estudiantes estudian alemán.
n = numero total de estudiantes en la clase.
5/9 n = 15
9/5 * 5/9 * n = 15 * 9/5
n = 27
Hay 27 estudiantes en la clase.
27 - 15 = 12
12 estudiantes no estudian alemán.
-1/2(2n + 4) + 6 = –9 + 4(2n + 1)
Answer: 1/3=n
Step-by-step explanation:
-1/2(2n + 4) + 6 = –9 + 4(2n + 1)
Distribute:
-1n-2+6=-9+8n+4
Combine like terms:
-1n-2+6=-9+8n+4
-1n+4=-5+8n
Add 1n on both sides:
-1n+4=-5+8n
-1n+1n+4=-5+8n+1n
4=-5+9n
Add 5 on both sides:
4+5=-5+5+9n
9=9n
Divide 9 on both sides:
9/9=9n/9
1=n

Answer:
6.75
Step-by-step explanation:
A of rectangle = 2*1.5=3
A or triangle= (7-2)*1.5/2 = 5*1.5/2 =3.75
Area trapezoid =A rectangle +Atriangle = 3+3.75=6.75
Answer:
C : 6.75 yd.
Step-by-step explanation:
first, you divide the trapezoid into two shapes, a square, and a triangle. For the square's area, you multiply 2yd and 1,5 yd to get 3 yd. Then for the triangle's area, since the bottom side of the trapezoid is a side for both the triangle and the square, the square already took 2yd if that makes sense. You multiply 5yd and 1.5 yd to get 7.5 yd. Since its a triangle, you divide the area of the triangle by 2, which is 3.75 yd. To get the total area of the trapezoid, you then add 3yd plus 3.75 yd to get 6.75 yd. ²
