4 0

Answer:

75 + 20 = 5 (15 + 4) = 5 × 19 = 95

Step-by-step explanation:

The prime factors of 75 are 3 × 5 × 5.

Again, the prime factors of 20 are 2 × 2 × 5

Therefore, the greatest common factor of 75 and 20 is 5.

Now, 75 + 20

= 5 × 15 + 5 × 4

= 5(15 + 4) {Using the distributive property of multiplication}

= 5 × 19

= 95 (Answer)

14. Given: 5x + 4y = 24, x + 7y= 11; Prove: y= 1<br> Statements<br> reasons
Semenov [28]

Answer:

Step-by-step explanation:

We can use the process of elimination as

5x + 4y = 24

5(x + 7y = 11) —>          5x + 35y = 55

5x + 4y = 24

-(5x + 35y = 55)

—————————

-31y = -31

-31y/-31 = -31/-31

y=1

Between which two ordered pairs does the graph of f(x) = one-halfx2 + x – 9 cross the negative x-axis?
Anit [1.1K]

Answer:

Step-by-step explanation:

we have that

f(x) = x^2 + x - 9

Using a graph tool

see the attached figure

The function represent a vertical parabola that open up

the vertex is a minimum-------> is the point (-0.5, -9.3)

The x-intercepts are the points when the y coordinate is equal to zero

The x-intercepts are the points (-3.5, 0)  and (2.5, 0)

so

the function cross the negative x-axis at point

therefore, the answer is

(-4, 0) and (-3, 0)
