Answer:

B) -2.5

Step-by-step explanation:

2x^2 + 5x -3 = 0

(2x - 1)(x + 3) = 0

2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1

x + 3 = 0, so x = -3 = ROOT 2

Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.

Answer:

$0.035

Step-by-step explanation:

Using distance between two points, it is found that Jose traveled 25 units of length to football practice.

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

First, Jose goes from his house, at (-6,8), to Tyrell's house, at (6,8), thus:

[tex]D_1 = \sqrt{(6 - (-6))^2 + (8 - 8)^2} = \sqrt{12^2} = 12[/tex]

Then, he goes from Tyrell's house, at (6,8), to the football field, at (6, -5), thus:

[tex]D_2 = \sqrt{(6 - 6)^2 + (-5 - 8)^2} = \sqrt{13^2} = 13[/tex]

The total distance is:

[tex]D = D_1 + D_2 = 12 + 13 = 25[/tex]

Jose traveled 25 units of length to football practice.

MARK ME BRAUNLIST PLZ.

Answer:

228cm^2

Step-by-step explanation:

Multiply 18cm by 10cm:

18 x 10 = 180cm^2

So we have the area of the biggest/top part: 180cm^2

For the bottom part:

You've said the length of the bottom side is 8cm.

We know the length of the biggest side: 24cm. And we know the length of the opposite side: 18cm. So, to find the length of the missing side, it's simple subtraction:

24cm - 18cm = 6cm

So now we have lengths for 2 sides: 8cm and 6cm.

Multiply these to give the area:

8cm * 6cm = 48cm^2

Add these areas of both shapes together to give total area:

180cm^2 + 48cm^2 = 228cm^2

Step-by-step explanation:

7 gold : 4 silver

It gives you 36 silver.

to get from 4 silver to 36 silver you multiply by 9.

you multiply the gold by the same amount 9.

7*9= 63

you can see that for every 7 gold pieces there is 4 silver pieces. they keep piling up the pieces until there's 36 silver pieces. now they wanna know how much gold there is.

that is really, really simple.

h(-3) means that we put the argument (-3) into the formula of the function everywhere where there is x.

h(x) = -3x - 10

so,

h(-3) = -3×-3 - 10 = 9 - 10 = -1

Answer:

-1

Step-by-step explanation:

h(x) = -3x - 10    

h(-3)            means to replace the x in the problem with the value of -3 and  

                   solve.

h(-3) = -3(-3) - 10

h(-3) =  9 - 10

h(3) = -1

Step-by-step explanation:

The number of overtime hours Bolton will need at his new position in other to make the same monthly income ls 10 hours per week.

New position :

Let the number of overtime hours required weekly = t

Hence,

(14.90 × 40) + 22.35t = 820

596 + 22.35t = 820

22.35t = 820 - 596

22.35t = 224

t = 224 / 22.35

t = 10

Therefore, he'll need 10 hours of overtime.

Answer:

X = 40°

Step-by-step explanation:

The triangle on the left is an Isosceles triangle which means it has 2 equal sides. So, to find the third angle, u have to minus 180 and both the base angles.

180° - 35° - 35°

= 110°

Then, minus 180 with the right triangle base bcs a straight line is 180°.

So,

180 - 110

= 70°

Now u got the right triangle base which is also an isosceles triangle so both angles are 70°

Now to find the third angle, minus 180 to both the base angles

180 - 70 - 70

= 40°

And that's your answer.

As mentioned in the question,
To raise the fraction to its highest terms by supplying the missing numerator.7/8=x/240.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
according to the question,
7 / 8 = x / 240
x = 7/8 × 240
x = 7 × 30
