Please take your time but I really need anyone's help!!!!

Answer:

a=12 b=9

Step-by-step explanation:

u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you

a+3/4a=21

a=4/4a

4/4a+3/4a=21

7/4a=21

4/7(7/4a=21)

a=12

plug in 12 for a in either equation

b=3/4*12

b=9

(21=12+b) -12

9=b

Answer:

Area of Rectangle = 28 cm²

Step-by-step explanation:

Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.

To find - What is the area of the shaded rectangle?

Solution -

The graph of the rectangle is as follows :

From the diagram, e can see that

Length of Rectangle = 7 units (cm)

Breadth of Rectangle = 4 units (cm)

We know that,

Area of Rectangle = Length × Breadth

                              = 7 × 4

                              = 28 cm²

⇒Area of Rectangle = 28 cm²

Step-by-step explanation:

1. Slope

2. Hypotenuse

Answer:

D

Step-by-step explanation:

all answers are x = 0. If we put 0 instead of X.

y=0^4+3×0^3-2×0+7

y=0+0+0+7

y=7

Answer:

5.6

Step-by-step explanation:

The equation is put in y = mx + b

where m = slope ( rate of change ) and b = y intercept

5.6 = m and 7 = b

Hence the rate of change for y = 5.6x + 7 is 5.6

Answer:

a Answers is A

b Answer is D

Step-by-step explanation:

he sayed that the X doubles in the first one so its ×2

and in the second one he sayed that the x is only triples so we dont have to Multiply we have to devide it 5/x/3=5/x ×1/3

Answer:

Component Form: v = <-1,6>

Magnitude of v: ||v|| = √37

Direction of v: θv = 100° (to the nearest degree)

Step-by-step explanation:

Component Form: v = <(5-6),(3-(-3))> = <-1,6>

Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37

Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.

Step-by-step explanation:

In order to find out what g is equal too,u must subtract 19 from both sides of the equation to get

g +19-19=38-19

the nineteens cancel out getting

g=38 -19

g=19

Answer:

28/3

Step-by-step explanation:

Dividing a fraction is the same as multiplying it by the reciprocal.

First, convert 4 and 2/3 to an improper fraction.

You get 14/3. Multiply that by the reciprocal of 1/2 (2/1) to get your answer.

14/3 * 2/1 = 28/3

Answer: M-2 or M substracted by 2

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

convert mixed number into improper fraction

15/2÷3/4

to divide by a fraction multiply by the reciprocal of that fraction

15/2×4/3

reduce the numbers with the greatest common factor 3

5/2×4

reduce the numbers with the greatest common factor 2

multiply the numbers

5×2=10

10 is your answer

Answer: 414628192

Step-by-step explanation: ok, so take 5+5=10

10+ 6355334= 6355344 + 64= 6355408

then do  463454432/2 which = 231727216 then

646355408-231727216=  414628192

Have a good day (^_^)

Answer:

y= -3/2X + 2

Step-by-step explanation:

we get the gradient by picking any two points from the graph( it a linear graph)

using the point:

(x,y)= (-2,5) , (4,-4)

using M= (y2-y1)/x2-x1)

we get our gradient to be -9/6 which is

-3/2

using the equation of a straight line graph which is

y-y1=m(x-x1) and the point (4,-4)

we get

y-(-4)=-3/2(x-4)

----> y+4= -3/2x + 6

make y subject of the formula to take the form

y=mx+c

we get :

y=-3/2x + 2
