Answer:

12-14i

Step-by-step explanation:

[tex](-1-3i)(3+5i)\\\\=-1(3)-1(5i)-3i(3)-3i(5i)\\\\=-3-5i-9i-15i^2\\\\= -3-14i-15i^2\\\\[/tex]

here we know that i^2=-1

[tex]=-3-14i-15(-1)\\\\=-3-14i+15\\\\=12-14i[/tex]

Answer: 11+23i

Step-by-step explanation:

(i+5)(3+4i)

First foil

3i+4i^2 +15+20i

Then combine like terms

23i+15+4i^2

i^2 = -1 so,

23i+15+4(-1)

11+23i

Answer:

32 x 3 - 5 = 91

Step-by-step explanation:

First multiply because of order of operations (PEMDAS,) to get 96. Then subtract 5 from 96, to get 91.

Answer:

yes

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

2+0<2is wrong if that's what you mean then the right answer is 2+0=2

the sign < means the number after it is bigger than the number before thus sign so its not the answer

Answer:

0.5

Step-by-step explanation:

the first significant figure is the non zero

Answer:

x (19) is your answer okkkkkk

Answer:

7250

Step-by-step explanation:

145,000

x

0.05

145000 / 100 = 1450.

1450 x 5 = 7250

Answer: 50% would be the correct answer.

Answer:

its x>-249

Step-by-step explanation:

this should be the answer cause x is 0 on the line and the 249 is negative so its much less than 0

Answer:

x>-3 (if the = is meant to be +)

Step-by-step explanation:

Distribute the 2: 2x+10>4

Subtract 10 from both sides: 2x>-6

Divide both side by 2: x>-3

Answer:

Undefined

Step-by-step explanation:

If a linear equation is organized in the form x=[a number], we know straight away that this line is a vertical line. This form is actually [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept of the line. Vertical lines do not have a y-intercept because they are parallel to the y-axis.

The slope of vertical lines is undefined.

Answer:

Approximately 50 square feet (50.24 to be exact)

Step-by-step explanation:

If you're using 3.14 for π, and the area of a circle is A=πr2,

(3.14)(4)^2 =?

(3.14)(16) = 50.24

Therefore the answer would be about 50 square feet.

Answer:

Y=-3x+0 or Y=-3x

Step-by-step explanation:

Y=mx+b

m=slope

b=y-intercept (where the line crosses the y axis)

The line crosses the Y axis at (0,0), so:

Y=mx+0 or

Y=mx

Slope:

Rise/run= Change in y/Change is x= 9/-3=-3

So:

Y=-3x+0 or

Y=-3x

Answer: 3x + y = 0

Step-by-step explanation: Remember that slope is represented by

rise over run from one point to the next on our graph.

To get from the point (0, 0) to (3, -9), we go down -9 units

so our rise is -9 and we run 3 units so our run is 3.

Our slope therefore or m = -9/3 or -3.

Our y-intercept is represented by the point where this line

crosses the y-axis which in this case is up 0 units.

So our y-intercept or b = 0.

Since we have the slope and y-intercept of our line,

we can now write its equation in y = mx + b form.

Since m = -3 and b = 0, that gives us y =-3x + 0.

Now we convert this equation to standard form.

Just add 3x to both sides to get 3x + y = 0.

So the equation of this lie is 3x + y = 0.

==========================================

Work Shown

45 girls : 15 boys

45/15 girls : 15/15 boys .... divide both parts by 15

3 girls : 1 boy

This tells us there are three times as many girls as there are boys.

We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.

Answer:

Part(A): The expression which represents the number of hours Matthew played soccer in a full week is [tex]5h + 6.5[/tex]

Part(B): the expression models her purchase is [tex]35.79-3b[/tex].

Step-by-step explanation:

Consider the provided information.

Part(A):

Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.

So the required expression is: [tex]5h + 6.5[/tex]

Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.

Part(B):

Mariah purchases three hair barrettes by using a gift card.

Let the cost of each barrette is b.

So the cost of 3 barrettes is: [tex]3b[/tex]

She uses a gift card with a balance of $35.79. Therefore subtract  [tex]3b[/tex] from $35.79.

Her purchase can be expressed as:

[tex]35.79-3b[/tex]

Hence, the required expression is [tex]35.79-3b[/tex].

Answer:

5h + 6.5

Answer:

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

Answer:

x     f(x)

-5   -30

-1    -10

2    5

3    10

4    15

Step-by-step explanation:

Let us solve the question

∵ The function f is defined by the rule f(x) = 5x - 5

∵ x = -5

→ Substitute x in f by -5 to find the value of f(-5)

∴ f(-5) = 5(-5) - 5 = -25 - 5 = -30

∴ f(-5) = -30

∵ x = -1

→ Substitute x in f by -1 to find the value of f(-1)

∴ f(-1) = 5(-1) - 5 = -5 - 5 = -10

∴ f(-1) = -10

∵ x = 2

→ Substitute x in f by 2 to find the value of f(2)

∴ f(2) = 5(2) - 5 = 10 - 5 = 5

∴ f(2) = 5

∵ x = 3

→ Substitute x in f by 3 to find the value of f(3)

∴ f(3) = 5(3) - 5 = 15 - 5 = 10

∴ f(3) = 10

∵ x = 4

→ Substitute x in f by 4 to find the value of f(4)

∴ f(4) = 5(4) - 5 = 20 - 5 = 15

∴ f(4) = 15

Answer:

y = -1/4x+2

Step-by-step explanation:

The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.

Answer:

A, y-intercept = (0,24)

Step-by-step explanation:

The y intercept is the one without a variable. You have to solve to find it in the other options.

Answer:

The first choice would be the best one.

Step-by-step explanation:

The y intercept occurs when x = 0 of the given polynomial.

All 3 answers will give you the correct answer. The y intercept is (0,24)

but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.

2x^2 when x = 0 is 0

16x when x = 0 is 0.

That only leaves m(0) = 24 found just by looking at it.

The second one also works. 2 (0+4)^2 -  8 = 32 - 8 = 24

And the third one as well 2(6)(2) = 24
