PLEASE ANSWER IN POINT SLOPE FORM
Answer:
y-4 =-5(x+1)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y-4 = -5(x- -1)
y-4 =-5(x+1)
Answer:
y-4 = -5 (x- (-1))
Step-by-step explanation:
blank 1 = -4
blank 2 = -5
blank 3 = -1

Hint: Remember to rationalize the denominator.
Answer:
[tex]\rm \dfrac{\sqrt2}{2}[/tex]
Step-by-step explanation:
A right angled ∆ is given to us and we need to find out the value of cos 45° ( with rationalized denominator ) . As we know that in a right angle ∆ , the value of cosine is ,
[tex]\rm\implies cos\theta =\dfrac{base}{hypotenuse} [/tex]
In the given triangle ,
Value of base = 1 Value of hypotenuse = √2On substituting the respective values ,
[tex]\rm\implies cos45^\circ =\dfrac{1}{\sqrt2} [/tex]
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
[tex]\rm\implies cos45^\circ=\dfrac{1(\sqrt2)}{(\sqrt2)(\sqrt2)} [/tex]
Simplify ,
[tex]\rm\implies \boxed{\pink{\frak{ cos45^\circ=\dfrac{\sqrt2}{2} }}}[/tex]

Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax. What is the total price of the television? A. $74.69 B. $298.74 C. $348.87 D. $448.12
Answer:
B
Step-by-step explanation:
349 ---100%
x ------ 20%
x= (349×20)÷100
x=69.8
349-69.8=279.2
279.2 ---100%
x-----7%
x=(279.2×7)÷100
x=19.54
Final result
279.2+19.54=298.74
And final result is B
The total price of the television is B. $297.74
Given that,
Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax.Based on the above information, the calculation is as follows:
[tex]= (\$349 \times (1- 0.20) + \$349 \times (1- 0.20) \times 0.07)\\\\= \$279.20 + \$19.544[/tex]
= $297.74

Which number line represents the solution set for the given inequality?
x + 1 ≤ -3 or -4x < -8
The solution to the system of equations is x≤ -4 and x > 2. Find the number line attached below:
Given the set of inequalities expressed as;
x + 1 ≤ -3 or -4x < -8
For the inequality expression x + 1 ≤ -3
x ≤ -3 - 1
x ≤ -4
For the inequality expression:
-4x < -8
Divide both sides by -4
-4x/-4 > -8/-4
x > 2
Hence the solution to the system of equations is x≤ -4 and x > 2. Find the number line attached below:

two complementary angles are in a ration of 2 3 find the measure of each angle
A complementary angle is 90 degrees. The ratio is 2:3 so the equation would be:
2x+3x=90
5x=90
x=18
One of the angles would be 2(18) or 36 degrees and the other angle would be 3(18) or 54 degrees.
36+54 is equal to 90 degrees so it checks out.

Hansen thinks his pet goldfish, Finn, might be lonely. So, Hansen buys another goldfish to keep Finn company. He also buys a large 10-gallon tank so the two fish can swim together. If Finn currently lives in a 2-quart fish bowl, how many times bigger is his new tank than his old bowl?
Answer:
Well, 1 gallon is 4 quarts so if Finn lives in a ½ Gallon tank divide 10 by 0.5 and you get 20, so his new tank is 20 times bigger than his old bowl.

Step-by-step explanation:
Using the formula
P = 2 (l + w)
Solving for w
w = P
2﹣l = 82

Step-by-step explanation:
69 total planks divided by 5 for each bookshelf.
That would be 69÷5=13.8
Seeing as you can't make .8 of a shelf, those planks would just be extra.

x2 - 6x + 9=-13+ blank
Answer:
to complete the square, you add (b/2)^2 on both side. in this case, b is -6, half of -6 is -3, -3 squared is 9, so:
x^2-6x+9=-13+9
(x-3)^2=-4
This quadratic equation have unreal solutions

Step-by-step explanation:
To complete the square, divide the coefficient of x by 2.
6 /2 = 3
Take square of 3 and add to both sides
3*3 = 9
x² - 6x + 9 = -13 + 9

Answer: 270
Step-by-step explanation:
1) Find DE
1 : 6
17 : x
Cross multiply
x = 17 * 6
x = 102
DE = 102
2) Compare the two triangles
1st (ABC)
side = 45
base = 17
2nd (ADE)
side = x
base = 102
[tex]\frac{x}{45} = \frac{102}{17}[/tex]
Cross multiply
17x = 102 x 45
17x = 4590
x = 4590/17
x = 270

¿Cuál es el perímetro de un rectángulo, si su diagonal mide 37 m y el ancho mide 12 m ?
Answer:
94 m
Step-by-step explanation:
Sea L definido como
L = la longitud del rectángulo, en unidades de metros.
Así, según el Teorema de Pitágoras, tenemos que
12 ^ 2 + L ^ 2 = 37 ^ 2
L ^ 2 = 37 ^ 2-12 ^ 2
L ^ 2 = (37 - 12) (37 + 12)
L ^ 2 = 25 * 49, de modo que
L = 5 * 7 = 35.
Por lo tanto, el perímetro = 2L + 2W = 2 (L + W) = 2 (35 + 12) = 2 (47) = 94 m

I went to the movies and bought 4 tickets. It cost me 23 dollars for the tickets after I applied my 5 dollar Tuesday discount. Create an equation for this situation where x is cost of each ticket. How much did each ticket cost? (answer asap pls)
Answer:
x= 5.75$
Step-by-step explanation:
23 divided by 4 = 5.75$ (without the discount it is 10.75$)
Answer:
each ticket=$7.
x=7
Step-by-step explanation:
The total price of your tickets AFTER applying your $5 discount was 23.
Therefore, the price of 4 tickets would be 23+5, aka 28.
We can first begin with,
4x-5=23
4x=23+5
4x=28
x=7.
