Example problem: Name thex and y intercepts for y=-2x + 1
x-intercept 0= -2x +1 y intercept y = -2(0)+1
-1 = -2x
y= 1
0.5 = x
Find the x and y intercepts for y = 8x-4
O x=8, y = 4
x = 0.5, y = -4
O x=2,y=-4
O x= -4, y = 8

Answers

Answer 1

Step-by-step explanation:

for x=8,y=4

4=8x-4

8x=4+4

8x=8

x=1

y=8 (8)-4

y=64-4

y=60

for x=0.5, y= -4

-4=8x-4

8x= -4+4

8x=0

x=0

y=8 (0.5)-4

y=4-4

y=0

for x=2,y=-4

-4=8x-4

8x=4-4

8x=0

x=0

y=8 (2)-4

y=16-4

y=12

for x= -4,y=8

8=8x-4

8x=8+4

8x=12

x=1.5

y=8 (-4)-4

y= -32-4

y= -36

Identify square root of 3 as either rational or irrational, and approximate to the tenths place.

Answers

Answer:

Irrational

[tex]\sqrt{3}[/tex] = approx. 1.7

Step-by-step explanation:

The square root of 3 is irrational, because 3 is not a perfect square.

For example, 4 is a perfect square, so the square root (2) will be rational.

The square root of 3 is 1.73205080757,

What is the inverse relation of the function whose equation

is y = 3x – 2?

oy = x

o y = 3x + 2

o y = 2x - 3

x + 2

y =

3

Answers

Answer:

The inverse of the function is;

x = (y + 2)/3

Step-by-step explanation:

Here in this question, we shall be calculating the inverse of a function.

The function is;

y = 3x - 2

Firstly, let w = x;

y = 3w -2

y + 2 = 3w

w = (y + 2)/3

Now replace w by x

x = (y + 2)/3

This is the inverse of the function

Solve the following equation for x? -5(1-5x)+5(-8x-2=-4X-8x

Answers

Answer:

-5

Step-by-step explanation:

-5(1-5x)+5(-8x-2) = -4x-8x

-5+25x-40x-10 = -12x

-15-15x = -12x

-15 = -12x + 15x

-15 = 3x

x = -15 ÷ 3

∴x = -5

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 14x - 2. The value of x is 7. The value of the expression at x =7 will be calculated as:-

E = 14x - 2

E = 14 x 7 - 2

E = 96

Therefore, the value of the expression at x = 7 will be 96.

What is the slope intercept form for this?

Answers

Slope intercept form is y=-2x-1


EXPLANATION

when you use distributive property, you get y=-2x+2-3 and when you combine like terms, you get y=-2x-1

(The reason it is +2 instead of -2 is because when you multiply negative by a negative they cancel each other out)

Simplify each using the distributive property and/or combining like terms:

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes. What is the largest number of groups she can have?

Answers

Given :

Miki has 104 nickels and 88 dimes.

She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.

To Find :

Largest number of groups she can have .

Solution :

In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .

Now , factorizing both of them , we get :

[tex]104=1\times 2\times 2\times 2\times 13[/tex]

[tex]88=1\times 2\times 2\times 2\times 11[/tex]

Form above , we can say that common factors are :

[tex]HCF=2\times 2\times 2=8[/tex]

Therefore , the largest number of groups she can have is 8 .

Hence , this is the required solution .

Find the midpoint of a segment with the given endpoints.
W(-2,5), X(3,-17) =

Answers

Answer:

The answer is

[tex]( \frac{1}{2} \: , \: - 6)[/tex]

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

W(-2,5) and X(3,-17)

The midpoint is

[tex]M =( \frac{ - 2 + 3}{2} , \: \frac{5 - 17}{2} ) \\ = ( \frac{1}{2} \: , \: - \frac{12 }{2} )[/tex]

We have the final answer as

The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=a+m n=m−a n = a − m n = −m − a

Answers

Answer: Option B.

Step-by-step explanation:

The given formula is

[tex]a=m-n[/tex]

where,

a = actual cost of an item.

m = Original price

n = Amount of coupon

We need to solve the formula for the amount of the coupon (n).

In means, we need to isolate n in the given formula.

We have,

[tex]a=m-n[/tex]

Subtract m form both sides.

[tex]a-m=m-n-m[/tex]

[tex]a-m=-n[/tex]

Multiply both sides by -1.

[tex]-(a-m)=n[/tex]

[tex]-(a)-(-m)=n[/tex]

[tex]-a+m=n[/tex]

So, [tex]n=m-a[/tex].

Therefore, the correct option is B.
