Answer:

x= 70 y= 70

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

x+y = 5

Put this equation in slope intercept form y = mx+b where m is the slope

y = -x +5

The slope of the line is -1

Perpendicular lines have slopes that multiply to -1

-1 * m = -1

m = 1

The slope of the perpendicular line is 1

Answer:

No, for any number to be divisible by 2, the one and only rule is that it's even. This number is odd

Answer:

245

Step-by-step explanation:

multiple the amount of rooms on each floor (35) by the amount of floors (7)

35x7=245 rooms

here,

a= 7 and b=10

then,

ab

= a × b

= 7 × 10

(replace a and b by its value)

= 70

therefore, ab =70......

Answer:

33.11 hope this helps

Step-by-step explanation:

she needs to pay $33.108 In order to leave a 24 percent tip.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Josefina's check at Sun Bistro is $26.70. she wants to leave a 24% tip

Bill of josefina = 26.70

Bill after 24% tip = 26.70 * (1 + 24%)

Bill after 24% tip = 26.70 * 1.24

Bill after 24% tip = 33.108

Therefore, In order to leave a 24% tip she needs to pay $33.108.

Answer:

As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.

First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]

z2=−4±42−4×1×16√2×1=−4±16−64√2

=−4±−48√2=−2±12−−√i=−2±23–√i

=4(−12±3√2)i

=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2

=4e2kiπ3

As this is the value of z2 , whereas we want z , we need to take the square roots of both sides

z=4–√ekiπ3+nπ , where n∈0,1

=2e(k+3n)iπ3

=2cis((k+3n)iπ3)

As we have two values of k and two values of n , this gives us four solutions.

Writing these angles in terms of degrees, we have: 60, 120, 240 and 300

Evaluating, we end up with the four solutions

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Step-by-step explanation:

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a

X1,2=(-4+-√[16–16*4])/2

After you solve that you substitute back z^2 = x

180° - 95° = 85°

x = 180° - 85° - 60°

Answer:

B

Step-by-step explanation:

Since the line bisect PQ then the length of the left segment must be equal to the right segment.

Hence

[tex]5x-3 = 11 -2x\\5x + 2x = 11 +3\\7x = 14\\x = 2[/tex]

When x = 2 we have

[tex]PM = 5(2) -3 = 10 -3 =7.[/tex]

So the answer is B

Answer:

b. B

Step-by-step explanation:

PM = RM

[tex]5x - 3 = 11 - 2x[/tex]

[tex]5x + 2x = 11 + 3[/tex]

Answer:

if i am rightthe two other angles arre 39

Step-by-step explanation:

if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102

180-102= 78

then since you need the other two angles all you do is divide it by 2

so 78/2= 39 so the two missing anlges are 39

Answer:

Answer:

(-2.5 , 1)

Step-by-step explanation:

the x- coordinates :

[(3×(-2)) + (1×(-4))] /(3+1)

= (-6 +(-4))/(4)

= -10/4

= -2.5

the y-coordinates :

[(3×(-2)) + (1×10)] / (3+1)

= (-6+10)/(4)

= 4/4

= 1

so, the coordinates are (-2.5 , 1)

Answer:

Step-by-step explanation:

Directed line segment from (−4,10) to (-2, -2).

The ratio = 3/1.

The coordinates are:

The domain is the set of all the x-values/inputs used by the function.  

The range is the set of all y-values/outputs used by the function.

For #1:

The domain is { 1, 0, -1, 4 } because those are the x-values.

The range is { 3, 5, 7, -6 } because those are the x-values.
