Someone please help me❤️ Urgently with at least 1

Oksanka [162]

Answer:

See step-by-step explanation

Step-by-step explanation:

Question 3: (4, -3)

Solving through elimination: Multiply the first equation by -3.

-3x+6y=-30

3x-5y = 27

Add. The x drops out.

y= -3

Substitute -3 in for y.

x-2y=10

x-2(-3)=10

x+6=10

x=4

Question 4: (2,5)

Solve through elimination: Multiply the second equation with 3.

$\frac{3}{2} x+y=8$

$\frac{9}{4} x-y=-\frac{1}{2}$

3/2= 6/4

15/4x=7.5

x=2

3/2 (2) + y = 8

3+ y =8

y=5

Question 5: (6,4)

Use your graph to graph.

$y=-\frac{1}{3} x+6$

Slope of -1/3

Y-intercept of 6 (0,6)

X-intercept of 18 (18,0)

$y=\frac{3}{2} x-5$

Slope of 3/2

Y-intercept of -5 (0,-5)

X-intercept of $\frac{10}{3}$ (

Question 6: (5, -7)

$Ax+2By=-41$

$4Ax-By=88$

$3A+2B(4)=-41$

$4A(3)-B(4)=88$

Solve by substitution:

How do I solve this math problem

Angelina_Jolie [31]

Answer:

Cross Multiply.

Step-by-step explanation:

Multiply the denominator (3) of one side and the numerator (n).

Then, multiply the numerator (2) of on side and the denominator (4) of the other.

3n = 8

You divide both sides by 3 to have n be by itself, equaling ~2.6 or 8/3.

The midpoint of RS is M(1, 2). One endpoint is R(-6, 6). Find the coordinates of endpoint S.

AysviL [449]

Answer:

The coordinates of point S are (8,-2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x1+x2}{2},\frac{y1+y2}{2})$

Let

Point S(x2,y2)

substitute the given values

$(1,2)=(\frac{-6+x2}{2},\frac{6+y2}{2})$

<em>Solve for x2</em>

$1=(-6+x2)/2\\2=-6+x2\\x2=2+6=8$

<em>Solve for y2</em>

$2=(6+y2)/2\\4=6+y2\\y2=4-6=-2$

therefore

The coordinates of point S are (8,-2)

Can you help me find the area?

pav-90 [236]

Answer:

52.72m

Step-by-step explanation:

half-circles)

$c = \pi {r}^{2} \\ c = 3.14 \times 16 = 50.24 \div 2 = 25.12$

rectangle)

$4 \times 6 = 24$

triangle)

${3}^{2} + {2}^{2} = {c}^{2} \\ 9 + 4 = 13 \\ \sqrt{13} = 3.6$

Add everything-

$3.6 + 25.12 + 24 = 52.72$
