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:

Good luck!

For what value(s) of p will the equation x^2=p have 2 real number solutions? Explain your reasoning?
Stolb23 [73]

Answer:

p > 0

Step-by-step explanation:

x² = p

x² - p = 0

A = 1, B = 0, C = -p

For 2 real roots:

B² - 4AC > 0

0² - 4(1)(-p) > 0

4p > 0

p > 0

In the given figure, the area of △ADE is 16 units. What is the area of △ABC?
Sunny_sXe [5.5K]

Answer:

(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.

Ratio of DE to BC is 4:6 => 2:3

To find area, we need to raise the ratio of length to power 2

(2/3)² = 16/x

4/9 = 16/x

x = (16*9)/4

x = 36cm²

Therefore, area of triangle ABC is 36cm²

(ii) Ratio of DE to BC is 4:8 => 1:2

(1/2)² = 25/x

1/4 = 25/x

x = 25*4

x = 100cm²

Therefore, area of triangle ABC is 100cm²

I'm not sure about the third question, sorry

Please help! find the distance of AG if A (4,4) and G (-1,-1)
DochEvi [55]

{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

By using distance formula :

\qquad \sf  \dashrightarrow \:  \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2}  }

\qquad \sf  \dashrightarrow \:  \sqrt{(4 - ( - 1)) {}^{2} + (4 - ( - 1)) {}^{2}  }

\qquad \sf  \dashrightarrow \:  \sqrt{(4  + 1) {}^{2} + (4  + 1) {}^{2}  }

\qquad \sf  \dashrightarrow \:  \sqrt{2(5) {}^{2} }

\qquad \sf  \dashrightarrow \: 5 \sqrt{2 }\:  \: units
