Answer:

7^5

Step-by-step explanation:

According to the Product Rule for Exponents, \frac{a^m}{a^n} = a^{m-n}

a = 7

m = 9

n = 4

So,

\frac{7^9}{7^4} = 7^{9-4} = 7^5

So, the answer is 7^5.

Hope this helps!!!

How would you substitute 2x+3y=12 and 4x=10+y
Helen [10]

Answer:

<h2>x = 3, y = 2</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}2x+3y=12\\4x=10+y&\text{subtract 10 from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=12&(1)\\4x-10=y&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\2x+3(4x-10)=12\qquad\text{use the distributive property}\\2x+(3)(4x)+(3)(-10)=12\\2x+12x-30=12\qquad\text{add 30 to both sides}\\14x-30+30=12+30\\14x=42\qquad\text{divide both sides by 14}\\\\\dfrac{14x}{14}=\dfrac{42}{14}\\\\x=3

\text{Put it ot (2):}\\\\y=4(3)-10\\y=12-10\\y=2

3 − m = −2 (m + 6); m = −15 Yes or No
Nimfa-mama [501]

Answer:

3 − m = −2 (m + 6); m = −15    Yes

5 (p + 3) = −35; p = −4            No

8q = 3 (10 + q); q = 6             Yes


Step-by-step explanation:

3 − m = −2 (m + 6)

3 - m = -2m - 12

m = -15

Answer is Yes


5 (p + 3) = −35

5p + 15 = -35

5p = - 50

p = -10

Answer is  No


8q = 3 (10 + q)

8q = 30 + 3q

5q = 30

q = 6

Answer is  Yes

Determine the zeroes of the quadratic function whose graphs are given below:​
eimsori [14]

Answer:

1. zeros are -2 and 1

2. zeros are -1 and 3

3. zeros are -3 and 1

4. zeros are -1

5. no zeros

6. no zeros

Step-by-step explanation:

Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
