8* x + y + y; use x=9, and y = 10​

Answer:

-8

Step-by-step explanation:

Create this equation into a y=mx+b form

8x-3y=24

-8x       -8x           -8 to solve for -3y

-3y=-8x+24

----    ---   ---              divide by -3 to leave y by itself

-3      -3   -3

y= 8

    --- x-8

     3

y intercept is -8

Answer: −8

Step-by-step explanation:

Subtract 8x from both sides of the equation.

−3y=24−8x

Divide each term by −3 and simplify.

y=8x/3−8

Reorder terms.

y=8/3x−8

Y-INTERCEPT = -8

Answer:

Step-by-step explanation:

The set up is a right angles triangle where;

Height of the building = 30feet (opposite)

Angle of elevation = 70 degrees

Length of the ladder (hypotenuse) = x

Using SOH trig identity;

sin theta = opp/hyp

sin 70 = 30/x

x = 30/sin 70

x = 30/0.9397

x = 31.93feet

Hence the ladder must be 31.93 feet long to reach the top of the building

Answer:

Distance is 6.7units to the nearest tenth.

Explanation:

To solve this problem, we the distance formula. And this is given as:

[tex]D = \frac{|a x + b y + c|}{\sqrt{a^2 + b^2}}[/tex]

We were given the equation:

y = 2 x + 4

This can also be rewritten as:

y – 2 x – 4 = 0.

Therefore, a = -2, b = 1 and c = -4

Also, we were given the points:

(x, y) = (–4, 11)

Making use of the above formula for distance, we have:

[tex]D = \frac{|-2\times -4 + 1\times 11 + -4|}{\sqrt{-2^2 + -4^2}}[/tex]

[tex]D = \frac{15}{\sqrt{5}}[/tex]

D = 6.7units (to the nearest tenth)

Answer:

The florist can make 11 regular bouquets and 21 mini bouquets

Step-by-step explanation:

The number of roses the florist has = 118 roses

The number of peonies the florist has = 226 peonies

The number of roses in each regular bouquet = 5 roses

The number of peonies in each regular bouquet = 11 peonies

The number of roses in each mini bouquet = 3 roses

The number of peonies in each mini bouquet = 5 peonies

1. The equation that gives the total number of roses to be used in both kinds of bouquet is given as follows;

Let r represent the number of regular bouquet the florist can make and let m represent the number of mini bouquet the florist can make, we have;

5·r + 3·m = 118...(1)

2. Similarly, we have;

11·r + 5·m  = 226...(2)

Making m the subject of the formula of both equations, and equating both values of m to find a common solution, we have;

m = (118 - 5·r)/3

m = (226 - 11·r)/5

(118 - 5·r)/3 = (226 - 11·r)/5

5 × (118 - 5·r) = 3 × (226 - 11·r)

590 - 25·r = 678 - 33·r

33·r - 25·r = 678 - 590 = 88

8·r = 88

r = 88/8 = 11

r = 11

The number of regular bouquet the florist can make = r = 11

m = (118 - 5·r)/3 = (118 - 5×11)/3 = 21

m = 21

The number of mini bouquet the florist can make = m = 21

The number of regular bouquet the florist can make = 11 bouquets

The number of mini bouquet the florist can make = 21 bouquets.

Answer:

Donna swims 8 km each week.

Step-by-step explanation:

To be able to find the answer, you have to consider that 1 km is equal to 1000 meters and with this, you can use  rule of three to find the kilometers in 8000 meters:

1 km  →  1000 meters

  x    ←   8000 meters

x=(1*8000)/1000=8 km

According to this, the answer is that Donna swims 8 km each week.

Answer:

Mr. Martin's statement is correct.

Step-by-step explanation:

First we select a value of q that is less than 6:

q = 3

Then we write the equation:

And solve for x:

The solution is positive because x > 0.

--

Then we select a value of q that is not less than 6:

q = 9

Then we write the equation:

And solve for x:

The solution is negative because x > 0.

The value of the polynomial's constant term is -4

Step-by-step explanation:

Given polynomial;

= -2m³ + m² - m + c

where;

c is the constant term

factor of the polynomial = m+1

then, f(m+1) = 0

m = -1

Substitute the value of m in the given polynomial and solve for the constant term "c";

-2m³ + m² - m + c = 0

-2(-1)³ + (-1)² - (-1) + c = 0

2 + 1 + 1 + c = 0

4 + c = 0

c = -4

Therefore, the value of the polynomial's constant term is -4

Answer:

Check whether the two ratios form a proportion or not: (i) 6 : 8 and 12 : 16; (ii) 24 : 28 ... 3. The first, third and fourth terms of a proportion are 12, 8 and 14 respectively. ... 5. If a : b = 4 : 5 and b : c = 6 : 7; find a : c. Solution: a : b = 4 : 5. ⇒ a/b = 4/5.

Answer:

Let the fourth term be x

7/14=25/x

7x=14*25

x=350/7

x=50

What is an Equation?

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.

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 data ,

The total number of schools = 5 schools

Let the schools be A , B , C , D , E

One of the schools sent boys and girls

The number of boys A = 16 boys

The ratio of boys to girls is = 1 : 2

So , the number of girls = 2 x number of boys

The number of girls A = 2 x 16

                                     = 32 girls

Now , the equation will be

The number of students sent to conference by school A = 16 + 32

The number of students sent to conference by school A = 48 students

Now , the equation will be

All the schools sent the same number of students

So , The total number of students = Total number of students in A x 5

The total number of students = 48 x 5

                                                 = 240 students

Therefore , the total number of students is 240 students

Hence , The total number of students who went to the conference was 240 students

Answer:

y=$3.75x

Step-by-step explanation:

$50 is equal to 'y'. 'x' is the number of days Mia goes to the coffee shop. For every day Mia goes to the coffee shop, she spends $3.75 on her favorite drink

The required expression for the balance gift card is y = 50 - 3.75x.

Given that,
Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shop she spends $3.75 on her favorite drink. To determine an equation to represent the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Total money spent on the drink = 3.75x
Money left in the gift card after paying 3.75x from the $50 gift card is = 50 - 3.75x.

So,
y = 50 - 3.75x

Thus, the required expression for the balance gift card is y = 50 - 3.75x.
