(10x^2+10x^3-9x^4)-(4x^3+?-8x^2)=-19x^4+6x^3+18x^2

Answer:

10x - 12y = 192

Step-by-step explanation:

Given the equation :

-5/8x + 3/4y = 12 - - - (1)

8x + 12y = 11 ___(2)

The equivalent form of the first equation which can eliminate the y term :

Multiply (1) by - 16 :

-5/8x * - 16 + 3/4y * - 16 = 12 * - 16

10x - 12y = 192

Hence, Adding the obtained equation and equation(2) will eliminate.

Answer:

G(x)=2/15x-6

Step-by-step explanation:

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,

x/(-6) + y/45 = 1

- 15x + 2y = 90

y = (15/2) x + 45

g(x) = (15/2) x + 45

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

-9+1/2 , -9-1/2

-8/2 , -10/2

-4,-5

Answer:

(x+4)(x+5)

Step-by-step explanation:

Let's factor x2+9x+20

x2+9x+20

The middle number is 9 and the last number is 20.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Addd together to get 9

multiply together to get 20

Can you think of the two numbers? hmmmmmm :D

Try 4 and 5:

4+5 = 9

4*5 = 20

Fill in the blanks in

(x+_)(x+_)

with 4 and 5 to g.et...

(x+4)(x+5)

Hope this helps :D

Answer:

At least $15.50

Step-by-step explanation:

Omar is planning to buy some new baseball shoes. He has already saved $22.50

The shoes cost at least 38 dollars.

At least means, greater than or equal to which is represented by the sign

≥

The inequality is given as

22.50 + x ≥ 38

x ≥ 38 - 22.50

x ≥ 15.5

Therefore, he would need to save at least $15.50

Answer:

-8

Step-by-step explanation:

What is the value of this expression? 6 + (-9) - (-5)

6 + (-9) - (-5)

= 6 - 9 + 5

Following the rules of BODMAS, addition comes first before subtraction

= 6 - 14

= - 8

6 + (-9) - (-5) = -8

Note:

- * - = +

- * + = -

+ * - = -

+ * + = +

Then using BODMAS

B - bracket

O - of

D - division

M - multiplication

A - addition

S - subtraction

Answer:

32 : 24 is smaller

Step-by-step explanation:

32 : 24 = 32/56, reduced is 4/7

30 : 22 = 30/52, reduced is 15/26

a common denominator is 182:

4/7 = 104/182

15/26 = 105/182

The answer is Part B I think. I'm not fully sure, but it sounds much more logical in my opinion.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Part A:

Mark did not round to the nearest hundreds, he rounded to the nearest tens.

Option A (Incorrect):

271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.

Option B (Incorrect):

271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.

Option C (Incorrect):

271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.

Option D (Correct):

271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.

Part B:

There are two ways to solve this question:

One way:

271 + 582 = 853

Round 853 to the nearest hundred for 900

(Note: Round 853 to the nearest tens for 850.)

Second way:

271 + 582

Round Numbers:

300 + 600

= 900
