Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The first step you need to do is plug in the numbers...

4(5)+(-4)

Then you will distribute the positive 1 but that won't change much...

4(5)-4

Then you'll have to multiply the 4 and 5 to get....

20 -4

Now from here should be a piece cake, so the answer is...

16\\

−10x − 5y ≥ 15 x + y ≤ −1 what are the quadrants containing a solution to the above system of linear inequalities.
Paraphin [41]
Let's convert these inequalities to Slope Intercept Form so that we can graph them easily.

<span>−10x − 5y ≥ 15
Add 10x to both sides.
-5y </span>≥ 10x + 15
Divide both sides by -5 and flip the inequality sign.
y <span>≤ -2x - 3

</span><span>x + y ≤ − 1
Subtract x from both sides.
</span><span>y ≤ -x − 1

When graphed, the solutions lay in Quadrants II, III, and IV. You can see this in the picture I've included.</span>

A straight line passing through A(3,2) and B(5,y) has gradient -2. find the value of y​
astraxan [27]

Step-by-step explanation:

gradient \:  =  \:  \frac{y2 - y1}{x2 - x1}

y2 = y , x2 = 5

y1 = 2 , x1 = 3

- 2 \:  =  \:  \frac{y - 2}{5 - 3}

-4 = y-2 ==> y = -2

What is the slope of the line?<br><br> 3(y-1)=2x+2
Aleks [24]

Answer: 2/3

Step-by-step explanation:

3(y-1) = 2x + 2

Expand: 3y - 3 = 2x +  2

Isolate the y by adding 3 to both sides: 3y = 2x +5

Isolate the y by dividing 3 from both sides: y = 2/3x +5/3

Remember, in y = mx + b, m = slope.

So, 2/3 is the slope.

F(x) = 2x2 + 12x + 1<br> Determine the vertex
Gnom [1K]

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 *  -1

2*-1

-2

(-3,-2) is the vertex
