Answer:

your answer is -285,112

Step-by-step explanation: first you do this

[tex]\frac{y1}{y2} \frac{x1}{x2} \\[/tex]

the numders should go like this

[tex]\frac{-15}{-16} \frac{-7}{19}[/tex]

then you cross multiply

[tex]-15*(19)\\-7*(-16)[/tex]

the answers to the multiplication

[tex]-15*(19)= -285\\-7*(-16)=112[/tex]

the answer is

-285,112

Answer:

[tex]y = -5x - 3[/tex]

Step-by-step explanation:

The data in the question are not properly presented.

See attachment for graph

To determine the graph, first we need to calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where x and y are corresponding values:

When x = -1; y = 2;

This implies [tex](x_1,y_1) = (-1,2)[/tex]

When x = 0; y = -3

This implies [tex](x_2,y_2) = (0,-3)[/tex]

So:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-3 - 2}{0 - (-1)}[/tex]

[tex]m = \frac{-3 - 2}{0 +1}[/tex]

[tex]m = \frac{-5}{1}[/tex]

[tex]m = -5[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x-x_1)[/tex]

Where:

[tex]m = -5[/tex]

[tex](x_1,y_1) = (-1,2)[/tex]

[tex]y - 2 = -5(x -(-1))[/tex]

[tex]y - 2 = -5(x +1)[/tex]

[tex]y - 2 = -5x -5[/tex]

Make y the subject

[tex]y = -5x - 5 +2[/tex]

[tex]y = -5x - 3[/tex]

Please note that the graph I attached may/may not be the right graph to your question.

However, if you follow the steps I used in answering this question, you'll get the right answer to your question.

Answer:

18.5

Step-by-step explanation:

It says

IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.

so HF is 10 cm .. half of that is 5 cm

GH is 13 cm.. Half of that is 6.5 cm

now we have IJ = 7 cm given

add all those.. you get 18.5 cm

Answer:

18.5

Step-by-step explanation:

35.

Segment IJ is a midsegment of triangle FGH, so

2HI = 2FI = FH

2HJ = 2JG = GH

FG = 2IJ

Perimeter of triangle IJH = IJ + JH + HI

IJ + JH + HI = 7 + 6.5 + 5 = 18.5

Answer:

14°

Step-by-step explanation:

We know that ∠PQS is a right angle.

We also know that ∠PQR is 76°.

So, to find ∠RQS, we can do 90°-76° = 14°

x° = 14°

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{x = 14 \degree}}}}[/tex]

Step-by-step explanation:

♨ First , let's know about complementary angles :

✎ Now, set up an equation and solve for x :

Move 76° to R.H.S ( Right Hand Side ) and change it's sign

➺ [tex] \sf{x \degree = 90 \degree - 76 \degree}[/tex]

➺ [tex] \boxed{ \bold{ \sf{x \degree = 14 \degree}}}[/tex]

And we're done !

Answer:

$0.44

Step-by-step explanation:

We find the unit rate for each taco

$1.32/3 for Pacos tacos

$4.20/5 for Taco Bell

We will then get

$0.44 per taco for Pacos tacos

$0.84 per taco for Taco Bell

$0.44 < $0.84

Pacos tacos is the better deal

Step-by-step explanation:

hope this answer will help u

The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

let the weight of basic kit be x and weight of designer kit be y.

The weight of 2 basic kites and 2 designer kites are 400g.

and, the weight of 4 basic kites and 1 designer kites are 440g.

So, the system of equation is

2x + 2y = 400.............(1)

4x + y = 440

y = 440 - 4x.............(2)

Solving equation (1) and (2), we get

2x + 2(440 - 4x) = 400

2x + 880 - 8x = 400

-6x = -440

x = 73.33

and, y= 440 - 4(73.33)

y = 146.68

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5

Answer:

First Number is 13

Second Number is 27

Step-by-step explanation:

let x = first number

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Step-by-step explanation:

He can row 3.5 miles in .25 hours.

If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.

Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.

3.5*4= 14 miles.

Answer:

0.33696

Step-by-step explanation:

Given that:

Probability of showing up head (p) = 0.6

Number of flips = number of trials = 5

Probability of getting more than 3 heads

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x> 3) = p(4) + p(5)

P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592

P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776

Hence,

0.2592 + 0.07776

= 0.33696

Following are the calculation to the probability:  

The probability to see the head [tex](p)= 60\%= 0.60[/tex]

Amount of flips = amount of tries = 5

Chances of getting and over three heads:

            [tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]

Hence,

                       [tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]

Therefore, the final answer is "0.34"

Answer: none

Step-by-step explanation:

Hey there!

3x - 5x + 5 = 20

• First COMBINE your LIKE TERMS

(3x - 5x) + (5) = 20

3x - 5x = -2x

• NEW EQUATION:

-2x + 5 = 20

• SUBTRACT by 5 on BOTH SIDES

Like: -2x + 5 - 5 = 20 - 5

Cancel out: 5 - 5 because that gives you a 0

Keep; 20 - 5 because it helps us solve for your x

**20 - 5 = 15**

• NEW EQUATION:

-2x = 15

• DIVIDE by -2 on BOTH SIDES

2x/-2 = 15/-2

Cancel out: -2x/-2 because that gives you 1

Keep: 15/-2 because it helps us solve for x (it also gives the value of “x”)

**AFTER SOLVING ABOVE WE FOUND OUR ANSWER**
