-7(x^2-5x+3) is the same as -7x^2-35x-21

Answer:

m perpendicular = −3 / 2

Step-by-step explanation:

y = m x+b

where m represents the slope and b, the y-intercept.

−3 y = −2 x + 5

divide all terms by - 3

−3 y − 3 = − 2 − 3 x + 5 − 3

y = 23 x − 53

in slope-intercept form

slope = m = 23

The slope of a perpendicular line is the

negative reciprocal of m

Answer: $10.7

Step-by-step explanation:

The following can be deduced from the question:

Total cost of items = $130

Percentage of Sales tax = 8.25%

Sales tax = Sales tax percent × Cost

Sales tax = 8.25% × $130

Sales tax = 8.25/100 × $130

= 0.0825 × $130

= $10.725

= $10.7

Answer: d) acute isoceles

Step-by-step explanation:

it has 2 acute angles and it's isoceles because it has 2 sides of equal length

Answer:

d. acute isosceles

Step-by-step explanation:

ABC had two sides that are equal so it is an isosceles triangle

<B = 90-44 = 46

A and C must be equal

A + B + C = 180

A + 46 + B = 180

2A = 180- 46

2A = 134

A = 67  so C = 67

All angles are acute

Answer:

r = 8

Step-by-step explanation:

Given

r + 6 = 14 ( subtract 6 from both sides )

r = 8

Answer:

Answer:

Step-by-step explanation:

[(3/2)⁰]⁻³

apply the exponent rule: (aᵇ)ˣ = aᵇˣ, a≥0

= (3/2)⁰ ⁽⁻³⁾

note that 0 * (-3) = 0 so,

=(3/2)⁰

apply exponent rule: a⁰ = 1, a≠0

= 1

Answer:

6 feet

Step-by-step explanation:

Let's form a proportion;

24                    x

____    =      _____ ,

 9                   2.25

24(2.25) = 9x,

54 = 9x,

x = height of soldier = 6 feet

Answer:

6 feet

Step-by-step explanation:

[tex]\frac{height of object}{length of shadow}[/tex]

Let the hight of the soldier be x

[tex]\frac{24}{9}[/tex] = [tex]\frac{x}{2.25}[/tex]

x = (24×2.25)/9 = 6ft

Answer:

c = -25

Step-by-step explanation:

8c + 120 = -180

Subtract 20 from both sides.

8c = -200

Divide both sides by 8.

c = -25

Answer:

C = -25

Step-by-step explanation:

Start by getting C alone, subtract 20 from the left side of the equal sign and subtract 20 from the right. (what you do on one side you MUST do to the other) this gives you 8c= -200. Divide 8 from 8c on the right side and divide 8 from -200 on the left side. This will give you c= -25

Answer:

A = 0.5714

basically the answer is option (d)

Answer:

1,75 m

Step-by-step explanation:

The radius is by definition half of the diameter and so the half of 3.5 m is 1.75 m

Answer:

1.75m

Step-by-step explanation:

d=3 ½

r=d÷2

so 3 ½ ÷ 2= 1.75

Answer:

130

Step-by-step explanation:

angle DEC and angle GHE are corresponding so they would be congruent or equal.

Answer:

130

Step-by-step explanation:

angle DEC and angle GHE are corresponding angles and they are same if they sit in parallel lines.

Answer:

1 1/3 = y

Step-by-step explanation:

12 = 6x + 3y

12 = 9y

12/9 = y

1 1/3 = y

Given :

Maria needs 23 ounces of water and 57 gallons of milk.

The cost of the milk is $9.20 per gallon and the cost of the water bottles is $2.99.

To Find :

How many ounces is the milk going to be measured in and how much would it cost.

Solution :

We know, 1 gallon = 128 ounces.

So, 57 gallon of milk = 57×128 = 7296 ounces.

Cost of 1 gallon milk = $9.20 .

So, cost of 57 gallon is = 57×9.20 = $524.4

Therefore, volume in ounces is 7296 and cost is $524.4 .

Hence, this is the required solution.
