Answer:

(−2, −8)

Step-by-step explanation:

Write the problem as a mathematical expression.

y = 7x + 6

4x − 3y = 16

Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16

y = 7x + 6

Simplify 4x − 3 (7x + 6).

−17x − 18 = 16

y = 7x + 6

Solve for x in the first equation.

Move all terms not containing x to the right side of the equation.

−17x = 34

y = 7x + 6

 Divide each term by −17 and simplify.

x = −2

y = 7x + 6

Replace all occurrences of x with −2 in each equation.

Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6

x = −2

Simplify 7 (−2) + 6.

y = −8

x = −2

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−2, −8)

The result can be shown in multiple forms.

Point Form:

(−2, −8)

Equation Form:

x = −2, y = −8

The equation Ax+By=10 goes through the coordinates (6,5) and (-2,-5).What are the values of A and B
wolverine [178]

Given:

The equation Ax+By=10 goes through the coordinates (6,5) and (-2,-5).

To find:

The values of A and B.

Solution:

We have,

Ax+By=10

It goes through the coordinates (6,5) and (-2,-5). It means these points will satisfy the equation.

A(6)+B(5)=10

6A+5B=10       ...(i)

A(-2)+B(-5)=10

-2A-5B=10       ...(ii)

Adding (i) and (ii), we get

(6A+5B)+(-2A-5B)=10+10

4A=20

Divide both sides by 4.

A=5

Put A=5 in (i), we get

6(5)+5B=10

30+5B=10

5B=10-30

5B=-20

Divide both sides by 5.

B=-4

Therefore, the values of A and B are 5 and -4 respectively.

jim is building a model of a square pyramid for a class project the side length of the square base is 12 inches and the slant he
yulyashka [42]
Surface area of a square pyramid is the area of the base + 4 times the area of one of the slanted sides.
Area of base = side length * side length
Area of side = (1/2) * side length * slant height
Don't forget that you have to multiply the area of the side by 4!

Step 1: 12 x 12 = 144
Step 2: 12 x 20 = 240 divided by 2 = 120
Step 3: 144 + 120 x 4

How do i do this question? someone help
lesya [120]
There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60
