State the slope and y intercept of this Y= -5x -1
Answer:
Slope: -5
y-Intercept: -1
Step-by-step explanation:
In the equation y = mx + b (its the form of a linear equation) the slope is m and the y-intercept is b. Comparing that to the problem, we can see that m = -5 and b = -1. So, the slope is -5 and the y-intercept is -1.
Answer:
y= -5x -1
y=mx+b
b- is y intercept
m-is slope

Sylvia needs to work at least 19 hours.
Step-by-step explanation:
Inequality: 10x + 120 ≥ 310
Subtract 120 from both sides;

Divide both sides by 10;
x ≥ 19
Solve by completing the square.
[tex]x^{2} -8x-5=-3[/tex]
Type in the step before you square both sides.
format ex. [tex](x+2)^{2} =-87[/tex]
Answer:
x^2 -8x -5 = -3
x^2 -8x -2 = 0
We complete the square by:
1) Moving the "non X" term to the right:
x^2 -8x = 2
2) Dividing the equation by the coefficient of X²
The coefficient of x is 1 so we don't do anything
3) Now here's the "completing the square" stage in which we:
• take the coefficient of X
that is -8
• divide it by 2
-8 ÷ 2 = -4
• square that number
-4*-4 = 16
• then add it to both sides of the equation.
x^2 -8x +16 = 2 +16
That becomes
(x -4)^2 = 18
we take the square root of both sides:
(x -4) = sqr root (18)
x1 = sqr root (18) +4
AND
(x+4) = sqr root (18) -4
x1 = sqr root (18) +4 = 4.2426406871 + 4 = 8.2426406871
x2 = sqr root (18) -4 = = 4.2426406871 - 4 = .2426406871

What are the solutions to the quadratic equation?
Answer: Choice C) [tex]x = 4\pm2\sqrt{10}[/tex]
This is the same as saying [tex]x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}[/tex]
=============================================================
Explanation:
First get everything to one side
x^2 + 13 = 8x + 37
x^2 + 13 - 8x - 37 = 0
x^2 - 8x - 24 = 0
Here we have a quadratic in the form ax^2+bx+c = 0
Note how a = 1, b = -8, c = -24
Those values are plugged into the quadratic formula below
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-8)\pm\sqrt{(-8)^2-4(1)(-24)}}{2(1)}\\\\x = \frac{8\pm\sqrt{160}}{2}\\\\x = \frac{8\pm\sqrt{16*10}}{2}\\\\x = \frac{8\pm\sqrt{16}*\sqrt{10}}{2}\\\\x = \frac{8\pm4*\sqrt{10}}{2}\\\\x = \frac{2(4\pm2\sqrt{10})}{2}\\\\x = 4\pm2\sqrt{10}[/tex]
This shows the answer is choice C.
The plus minus breaks down that equation these two solutions
[tex]x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}[/tex]

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.1%. How much will the customer earn in one year?
Given:
Principal amount = $3000
Rate of simple interest = 1.1%
To find:
The amount that the customer will earn in one year.
Solution:
Formula for simple interest is
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time in years.
Substituting P=3000, r=0.011 and t=1, we get
[tex]I=3000\times 0.011\times 1[/tex]
[tex]I=33[/tex]
Therefore, the customer will earn $33 in one year.

The solution is, ΔABC ≅ ΔFDE by SAS congruence rule.
The correct option is (1).
What are congruent triangles?Congruence is a phrase used frequently in mathematics to refer to a harmonious connection, comprehension, or correlation. A geometric figure is said to be congruent or to be in the relation of congruence if it is feasible to superimpose it on another so that their whole surfaces match. Two triangles are said to be congruent when two sides and their included angles in one triangle are equal to two sides and their included angles in the other.
here, we have,
As per the given data:
In ΔABC :
∠A = 63°
AC = 2.2
In ΔFED :
∠F = 63°
FE = 2.2
By using the distance formula, we can find AB and FD.
From the coordinates, as we can see in the diagram
FD = 2 units
Similarly,
AB = 2 units
Now from SAS congruence rule:
AB = FD (Both are 2 units)
∠A = ∠F (given)
AC = FE (given)
Hence, ΔABC ≅ ΔFDE by SAS congruence rule.

5.- Andrés se comió 1/5 de los bombones de una caja y Ana 1/2 de la misma. ¿Qué fracción de bombones se comieron entre las dos?. Si quedaron 12 bombones, ¿cuántos bombones tenía la caja? (Solución)
Answer:
La fracción de bombones que se comieron entre los dos es [tex]\frac{7}{10}[/tex]
La caja tenía 40 bombones.
Step-by-step explanation:
Sabes que Andrés se comió 1/5 de los bombones de una caja y Ana 1/2 de la misma. Para conocer la fracción de bombones que se comieron entre ambos, debes sumar las fracciones que comieron cada uno:
[tex]\frac{1}{5} +\frac{1}{2}[/tex]
Para hacer suma de fracciones con distinto denominador, lo primero que hay que hacer es determinar un denominador común. Para eso debes calcular el mínimo común múltiplo (mcm) entre los denominadores.
En este caso, el mcm entre 5 y 2 es 10.
Ahora tienes que multiplicar cada numerador por el número que hayas multiplicado el denominador. Para ello, dividís el m.c.m entre el denominador inicial y el resultado se multiplica por el numerador de esa fracción:
10÷5= 2 ⇒ 2*1= 2 Por lo tanto, 2 es el numerador de la primera fracción.10÷2= 5 ⇒ 5*1= 5 Por lo tanto, 5 es el numerador de la segunda fracción.Entonces:
[tex]\frac{1}{5} +\frac{1}{2}=\frac{2}{10} +\frac{5}{10}[/tex]
Ahora simplemente sumas los denominadores:
[tex]\frac{1}{5} +\frac{1}{2}=\frac{2}{10} +\frac{5}{10}=\frac{7}{10}[/tex]
La fracción de bombones que se comieron entre los dos es [tex]\frac{7}{10}[/tex]
Sabes que quedaron 12 bombones en la caja. Representando 1 la cantidad total de bombones, y si se comieron 7/10 de la caja, entonces quedaron:
[tex]1-\frac{7}{10}[/tex]
Restando de manera similar al procedimiento usado para la suma se obtiene:
[tex]1-\frac{7}{10}=\frac{3}{10}[/tex]
Finalmente podes aplicar la siguiente regla de tres: si 3/10 representa los 12 bombones que quedaron en la caja, entonces en 1 (que representa la cantidad total de bombones) cuantos bombones hay?
[tex]cantidad total de bombones=\frac{1*12}{\frac{3}{10} }[/tex]
cantidad total de bombones=40
La caja tenía 40 bombones.

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−3, −4). Which map shows the correct location of the movie theater?
1; A coordinate grid with a point at 3 units to the right and 4 units down from the origin labeled movie theater.
2; A coordinate grid with a point at 3 units to the left and 4 units down from the origin labeled movie theater.
3; A coordinate grid with a point at 3 units to the right and 4 units up from the origin labeled movie theater.
4; A coordinate grid with a point at 3 units to the left and 4 units up from the origin labeled movie theater.
Answer:
The 1st choice
Step-by-step explanation:
Let a point is defined as P(a,b).
If a>0, then point is a units right from origin and if a<0, then then point is a units left from origin.
If b>0, then point is b units up from origin and if b<0, then then point is b units down from origin.
It is given that the location of the movie theater is at (2, −3).
In the given point a=2>0 and b=-3<0.
A coordinate grid with a point at 2 units to the right and 3 units down from the origin labeled movie theater.

so an inequality would be t is greater than or equal to 0, and you can write this as t [tex]\geq[/tex] 0
4 is just saying what t [tex]\geq[/tex] 0 in word form: t is greater than or equal to 0
