Answer:

3/4 =x        -7=x

Step-by-step explanation:

y = (4x - 3)(x + 7)

To find the x intercepts, set y=0

0 = (4x - 3)(x + 7)

Using the zero product property

0 = 4x-3    0=x+7

3 = 4x           -7=x

3/4 =x        -7=x

Answer:

x - intercepts are (3/4 , 0) &  (-7 , 0)

Step-by-step explanation:

y = (4x - 3)(x + 7)

At x-intercept, y=0

(4x - 3)(x + 7) = 0

4x - 3 = 0    ;  x + 7 = 0

  4x = 3       ; x = -7

    x = \dfrac{3}{4}      ; x = -7

Answer:

The value of x is -29 and the value of y is -26

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding angles and its corresponding sides are congruent

so

The length of the corresponding sides must be equal

-2x+2y=6 ----> equation A

-7x+8y=-5 ----> equation B

Note

The length of one side of the triangle equal to -5 is not logical, however we will continue with the resolution of the problem for didactic purposes.

Solve the system by graphing

Remember that

the solution of the system of equations by graphing is the intersection point both graphs

using a graphing tool

The solution is the point (-29,-26)

see the attached figure

therefore

The value of x is -29 and the value of y is -26

Wich method can you use yo decide wich of several integers has the greatest value?
serg [7]

Answer:

C

The integer with the greatest value is the one that is farthest to the right hand side of the number line

Step-by-step explanation:

The number line is constructed in a way such that we have a center point of zero with positive values to the right of the number line and negative values to the left of the number line.

Moving deeper right, we have an increase in positivity, with the more positive values rightwards, indicating an increase in the numbers to the right

Moving to the left, we have an increase in negativity, but a decrease in value. The negative numbers closer to zero are more positive and command higher values than the values which are farther from zero.

What these indicates is that the more rightward a number, the greater its value

The area of a square in 169 square centimeter. What's its perimeter? Pls explain how you found the answer​
Lubov Fominskaja [6]

Answer:

Since the area of the square is 169 you think what times what equals 169 which is 13, so 13*13=169,

which makes your length and width 13 so 13*4= 52centimeters

52 centimeters
