Hey there!!

Let us take the first number as ' x '

According to the question

The second number exceeds the first number by 15

hence, the second number = x+15

The sum of both the numbers = 69

which means

x + x + 15 = 69

2x+15 = 69

Subtracting by 15 on both sides

2x + 15 - 15 = 69 - 15

2x = 54

dividing by  2 on both sides

x = 27

first number = 27

second number = 27 + 15

= 42

Hope my answer helps!

Answer:  The graph becomes narrower

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k   where

  • |a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
  • (h. k) represents the vertex

A vertical stretch means the curve gets narrower.

A vertical shrink/compression means the curve gets wider.

Can someone please solve this problem for me?
statuscvo [17]

Answer:

5 and 7.

Step-by-step explanation:

Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:

*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.

x *(x+2)=35

Expanding, you get:

x^{2}+2x = 35.

And moving the 35 to the other side, you get a simple quadratic.

x^{2}+2x -35 =0.

Solving by factoring:

(x+7)(x-5)

This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).

The sum of eight times a number and fifteen is seven
asambeis [7]
8x+15=7

In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.

Which value of x is in the solution set of -3X+8≥14? ) A. -3 B. -1 C. 0 D. 3 ​
romanna [79]

Answer:

A

Step-by-step explanation:

Solving for x:

-3x + 8 ≥ 14

-3x ≥ 6

x ≤ -2

Notice the sign gets reversed when you divide or multiply by a negative number.

The only option less than -2 is -3, A.

Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation.  This can save time on tests like the SAT or ACT.

Let's try it:

-3(-3) + 8 = 9 + 8 = 17

-3(-1) + 8 = 3 + 8 = 11

-3(0) + 8 = 0 + 8 = 8

-3(3) + 8 = -9 + 8 = -1

So you can see the answer is A.
