Find the x - and y -intercepts of the graph of the linear equation -4x+8y=-16 .

Answers

Answer 1

Answer:

x: (4, 0)y: (0, -2)

Step-by-step explanation:

To find the x-intercept, set y=0 and solve for x. That will mean dividing by the coefficient of x:

-4x +0 = -16

x = -16/-4 = 4 . . . . the x-intercept

To find the y-intercept, set x=0 and solve for y. That will mean dividing by the coefficient of y:

0 +8y = -16

y = -16/8 = -2 . . . . the y-intercept

The x- and y-intercepts are (4, 0) and (0, -2), respectively.

Additional comment

The standard form equation of a line, ax+by=c, is especially nice for finding the intercepts, as they are always (c/a, 0) and (0, c/b). Once you see this, you can do a question like this in your head.

25/100

then you find what number multiply by 25 gives 150

which is 600

or 150 ÷ 25/100 which also gives 600

so 600 is the number

h(x)=2x+5 for h(x+3)

pls help aaaaaaaaaaaa i

Answers

Answer:

According to transitive Property of equality : If a =b and b = c then a = c

In this problem you are given with 2 equations:

h(x) = - 2x + 5 ---- 1

h(x) = 3 ------ 2

Apply transitive Property of equality to equation 1 and 2

- 2x + 5 = 3 Now solve for x.

-2x + 5 - 5 = 3 – 5 subtract 5 on both sides.

-2x = -2

(-2x)/(-2) = (-2) / (-2) Divide with -2 on both sides.

X = 1

Which of the following lines has a negative slope?
Is it Red
Is it Black
Is it Blue

Answers

Answer:

black line <3

Step-by-step explanation:

the slope is -2 :)

A negative slop occurs when the rate of change is negative. Looking at the options we have, we can pick a point from each line. The Red line will display a positive slop, the Blue line will display a positive slope, but the Black line will display a negative slope. Therefore, the Black like has a negative slope.

Which product is greater than 63?

7/8 x63
3/2 x 63
4/5 x 63
2/3 x 63

Answers

Answer:

The answer is 3/2 x 63

Step-by-step explanation:

3/2*63 = 189 / 2 = 94.5

7/8*63 = 441 / 8 = 55.125

2/3*63 = 126 / 3 = 42

4/5*63 = 252 / 5 = 50.4

Therefore the answer is 3/2 x 63 because it’s product is greater than 63.

Answers

Step-by-step explanation:

the triangle is an Isosceles triangle

let the another two angles be 2x

and apply angle sum property of triangle here

2x + 72° = 180

2x = 180 - 72

2x = 108

x = 108/2 = 54

therefore,

angle 2 = 54°

a/q

angle 2 = -9 + 7x

now,

54° = -9 + 7x

-9 + 7x = 54°

7x = 54 + 9 = 63°

x = 63/7 = 9

x = 9

therefore, value of x is 9.

His grandmother is sick, so Hassan is making a pot of bean soup to bring for dinner. The recipe calls for equal amounts of 3 kinds of beans: kidney, pinto, and black. In all, Hassan uses 2 1/4 cups of beans in the soup.

Use an equation to find the amount of each kind of bean Hassan uses in the soup.

Answers

Answer:

0.75 cup

Step-by-step explanation:

K + p + b = 2 1/4

K = p = b

Sence all beans are equal we can divide 2 1/4 by 3

2 1/4 / 3 = 3/4

Finite geometric series:

Hi, I want to ask a question, is about... for example, take the sequence 1,2,4,8,... Notice that each number is twice the value of the previous number. So, a number in the sequence can be represented by the function f(n) = 2^n-1. One way to write the sum of the sequence through the 5th number in the sequence is E^5 n-1^2n-1. This equation can also be written as S5 = 2^0 + 2^1+2^2+2^3+2^4. If we multiply this equation by 2, the equation becomes 2(S5) = 2^1+2^2+2^3+2^4+2^5.

What happens if I subtract the two equations and solve for S5? Can I use this information to come up with a way to find any geometric series Sn in the form E^a n-1^bn-1?

The algebraic expression that represents twice the sum of some number and 3 is?

2(n + 3)

2 + n + 3

2n + 3

Answers

Answer:

2(n+3)

Step-by-step explanation:

The sum to 3 = n+3

That sum doubled (~twice) = 2(n+3)

Answer:

2(n+3)

Step-by-step explanation:

Let's look at the statement:

'twice the sum of some number and 3'

Twice means 2 multiplied by something.

What is that something? It is the sum of some number and 3.

Let's replace the some number with variable n.

So it becomes the sum of n and 3, which translates to n+3.

So you put the two parts together:

2 multiplied by (n+3), rewritten as 2(n+3).
