4,7

Step-by-step explanation:

17x+6=19x-2(being vertically opposite)

6+2=19x-17x

8=2x

x=8/2

x=4

10x-5=9+8x(being corresponding angle)

10x-8x=9+5

2x=14

x=14/2

x=7

Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form. What is the value of c in her equation

Zolol [24]

Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form

The standard form of quadratic equation is

$y= ax^2 + bx + c$

When y=0 then the standard equation becomes

$0= ax^2 + bx + c$

Now we compare the given equation $0 = -x^2 + 4x - 7$ with $0= ax^2 + bx + c$ and find the value of a, b,c

-x^2 can be written as -1x^2

$0= ax^2 + bx + c$

$0 = -1x^2 + 4x - 7$

a= -1 , b=4 and c=-7

The value of c is -7

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

The school is 625 meters far from Alex house. It took him 15 minutes to go from home to school, and run back to home in 10 minut

anygoal [31]

It is given in the question that

The school is 625 meters far from Alex house. It took him 15 minutes to go from home to school, and run back to home in 10 minutes.

Total distance is 625 meters and total time taken is

$(10+15) minutes=25minutes$

Average speed is

$\frac{total \ distance \ travelled}{total \ time \ taken}$

$= \frac{625}{25}meter/minute = 25 meter/minute$
