Answer:

[tex]x > 5[/tex]

Step-by -step explanation:

Solving inequalities is similar to solving equations.

[tex]5x + 10 > 35[/tex]

Subtract 10 from both sides.

[tex]5x > 25[/tex]

Divide by 5 from both sides to isolate the x.

[tex]x > 5[/tex]

Step-by-step explanation:

[tex]5x + 10 > 35 \\ \: 5x > 35 - 10 \\ 5x > 25 \\ x > 5[/tex]

8.7 is greater than 8.5 because the 7 is more than the 5 and the number 5 is less. Hope this helps :)

Answer:

Step-by-step explanation:

a) Si se suman las probabilidades de venta, es decir:

Probabildad de vender 0 auto ( es decir que no vendió) = 0,19

Probabildad de vender 1 auto                                              = 0,38

Probabildad de vender 2 autos                                            = 0,29

Probabildad de vender 3 autos                                            =0,15

Da por resultado:  1,01

1,01 > 1  

Ninguna probabilidad puede ser mayor que

b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad

d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras  tipo ( diamante, trebo, corazones y el otro).

La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.

La probabilidad de que sea corazones y negra s 1/4*1/2  = 1/8

Luego no hay error en esta aseveración

Answer:

D

Step-by-step explanation:

It cannot be A or B because you already have both of your angles, and it cannot be C because the sides do not line up. By the process of elimination it will be D.

Answer:

D

Step-by-step explanation:

AAS = angle angle side

we already have the 2 angles so it cant be A or B. we need to find the equal corresponding side lengths.  C is incorrect because side BC is not corresponding to side DF. therefore, it is D. sorry im bad at explaining but i hope this helped :)

[tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ), then

the product of the roots = [tex]\frac{c}{a}[/tex]

2x² + 4x + 7 = 0 ← is in standard form

with a = 2, c = 7 , thus

product of roots = [tex]\frac{7}{2}[/tex]

Answer:

y=14x-12

Step-by-step explanation:

in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.

Answer:

a. Plan B; $4

b. 160 mins; Plan B

Step-by-step explanation:

a. Cost of Plan A for 80 minutes:

Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:

f(80) = 8

This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.

Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.

Plan B will cost $12.

Therefore, Plan B cost more.

Plan B cost $4 more than Plan A ($12 - $8 = $4)

b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.

At 160 minutes, they both cost $16

The plan that will cost less if the time spent exceeds 160 minutes is Plan B.

Answer:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Step-by-step explanation:

Madelyn and her children went into a movie theater and she bought $39 worth of bags of popcorn and pretzels. Each bag of popcorn costs $6.50 and each pretzel costs $3.25. She bought 4 times as many pretzels as bags of popcorn. Graphically solve a system of equations in order to determine the number of bags of popcorn, x,x, and the number of pretzels, y,y, that Madelyn bought.

\underline{\text{Variable Definitions:}}

Variable Definitions:

​

the number of pretzels

One bag of popcorn costs $6.50, so xx bags of popcorn cost 6.50x.6.50x. One pretzel costs $3.25, so yy pretzels cost 3.25y.3.25y. The total 6.50x+3.25y6.50x+3.25y equals \$39:$39:

6.50x+3.25y=39

6.50x+3.25y=39

Since Madelyn bought 4 times as many pretzels as bags of popcorn, there are more pretzels, so if we multiply 4 by the number of bags of popcorn, we will get the number of pretzels, meaning yy equals 4x.4x.

y=4x

y=4x

The xx variable represents the number of bags of popcorn and the yy variable represents the number of pretzels. Since the lines intersect at the point \left(2, 8\right)(2,8) we can say:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Answer:

The coordinates of the point P is (0,0)

Step-by-step explanation:

Here, we want to find the coordinates of point P which divides the segment MN in the ratio 2 to 1.

Mathematically, what we shall use here is the internal division formula;

The internal division formula is given as follows;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

From the question;

x1 = -4

x2 = 2

y1 = 4

y2 = -2

m = 2

n = 1

By substituting, we have;

(1(-4) + 2)2))/(1 + 2) , (1(4) + 2(-2))/(1+2)

= (-4 + 4)/3 , (4-4)/3

= (0,0)

Answer:

Step-by-step explanation:

Proportional relationship means,

x ∝ y

x = ky

[tex]\frac{x}{y}=k[/tex] where 'k' is the proportionality constant.

From table (1),

[tex]\frac{1}{5}=\frac{2}{9}\neq \text{Constant}[/tex]

Therefore, relationship is not proportional.

From table (2),

[tex]\frac{1}{6}=\frac{3}{18}=\text{constant}[/tex]

True.

So the relationship will be proportional.

From table (3),

[tex]\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}[/tex]

Which is constant.

Therefore, relationship will be proportional.

From table (4),

[tex]\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103[/tex]

Which is constant for every term.

Therefore, relationship will be proportional.
