Can someone please help me !!

Answer:

-1

Step-by-step explanation:

8x - 10 = 70

8x = 70 + 10

8x = 80 / : 8

x = 10

Answer:

600

Step-by-step explanation:

Note that 600 is exactly half way between 400 and 800, and conclude therefore that 600 is the midpoint.

Answer:

361/50 or 7[tex]\frac{11}{50}[/tex]

Step-by-step explanation:

7.22 = 722/100 = 361/50 = 7 11/50

The number 7.22 can be written using the fraction 722/100 which is equal to 361/50 when reduced to lowest terms.

It is also equal to 7 11/50 when written as a mixed number.

You can use the following approximate value(s) for this number:

7.22 =~ 7 2/9 (if you admit an error of = 0.030779%)

361/50 =~ 7 1/4 (if you admit an error of 0.415513%)

7.22 =~ 7 (if you admit an error of -3.047091%)

Answer:

45

Step-by-step explanation:

Answer:

Step-by-step explanation:

First choose two points on the line,

Let the points are A and B.

From point A to B we are moving downwards by (5 - 1 = 4 units)

Therefore, Rise = -4

Horizontal distance between A and B = 2 units

Therefore, Run = 2

Since, slope of a line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

Slope = [tex]\frac{-4}{2}[/tex]

          = -2

Answer:

B(-2,7) r=6

Step-by-step explanation:

Circle Equation:

(x−h)^2+(y−k)^2 =r ^2

h= -2

k= 7

r=sqroot of 36 which is 6

Answer:

k = anything that is less than 2, so 1, 0, -1, -2, -3, -3 1/4, etc.

Answer:

I think the answer is 200 feet

Step-by-step explanation:

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A right-angle triangle has sides with lengths 200 ft and 200 ft.

By Pythagoras theorem, we have

H² =  P² + B²

H² = 200² + 200²

H² = 40000 + 40000

H² = 80000

H  = 200√2

H  = 282.84 ft

Alma is going to walk through the park from Point A to Point B is 282.84 ft.

Answer:

the length of the unknown side of the right angle triangle is 1 cm

Step-by-step explanation:

The computation of the length of the unknown side of the right angle triangle is shown below:

= √9^2 - √8^2

= √81 - √64

= 9 - 8

= 1 cm

Hence, the length of the unknown side of the right angle triangle is 1 cm

Answer:

[tex]f(x) = {x}^{2} - 13x + 30[/tex]

Step-by-step explanation:

A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).

f(x) = (x-3)(x-10)

f(x) = x^2 - 13x + 30

Answer:

number of hours is 64

amd number of washes is 12

Answer:

12(4) +6

48+6 = 54

y=54

Step-by-step explanation:

Step-by-step explanation:

Given function: y = 12x + 6

Input: x = -4

Replacing the value of x in function y,

y = 12 x (-4) + 6

y = -48 + 6

y = -42

Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!
