Answer:

x=63

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given

3 - 4x = - 60 + 3x ( subtract 3x from both sides )

3 - 7x = - 60 ( subtract 3 from both sides )

- 7x = - 63 ( divide both sides by - 7 )

x = 9

Answer:

If we rent the same car from both companies it would take 8 days

Step-by-step explanation:

Johnson's   50+2x

Martinez     30+4x

a) [tex]10[/tex] additional days are required for both to cost the same.

b) The cost is [tex]70[/tex]$.

At Johan's Rental:

Rent[tex]=(50+2x)[/tex]$

At Martinez Rent:

Rent[tex]=(30+4x)[/tex]$

For both the cost same

[tex]50+2x=30+4x[/tex]

[tex]2x-4x=30-50[/tex]

     [tex]-2x=-20[/tex]

         [tex]x=10[/tex]

[tex]\therefore[/tex] [tex]10[/tex] additional days are required for both to cost the same.

Cost[tex]=(50+2x)[/tex]

       [tex]=50+2\times 10[/tex]

       [tex]=50+20[/tex]

       [tex]=70[/tex]

Answer:

Slope is - 2 because The slope-intercept form is y=mx+b where m is the slope value. In the equation y=-2x , the m value is - 2 .

Step-by-step explanation:

f(x) = 2x^2 - 7x + 3

f(0) = 2(0)^2 - 7(0) + 3

= 0 + 0 + 3

= 3

f(x) = 2x^2 - 7x + 3

f(-2) = 2(-2)^2 - 7(-2) + 3

= 8 + 14 + 3

Answer:

[tex]\huge\boxed{\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%}[/tex]

Step-by-step explanation:

Two ways.

1. Convert to the decimal:

[tex]\dfrac{4}{7}=4:7=0.\overline{571428}\\\\\dfrac{5}{8}=5:8=0.625\\\\0.7=0.7\\\\72\%=\dfrac{72}{100}=0.72[/tex]

therefore

[tex]0.\overline{571428}<0.625<0.7<0.72}[/tex]

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

2. Convert to the fractions with common denominator.

[tex]\dfrac{4}{7};\ \dfrac{5}{8}\\\\0.7=\dfrac{7}{10}\\\\72\%=\dfrac{72}{100}=\dfrac{18}{25}[/tex]

[tex]LCD=7\cdot8\cdot5\cdot5=1400\\\\\dfrac{4}{7}=\dfrac{4\cdot200}{7\cdot200}=\dfrac{800}{1400}\\\\\dfrac{5}{8}=\dfrac{5\cdot175}{8\cdot175}=\dfrac{875}{1400}\\\\0.7=\dfrac{7}{10}=\dfrac{7\cdot140}{10\cdot140}=\dfrac{980}{1400}\\\\72\%=\dfrac{72}{100}=\dfrac{72\cdot14}{100\cdot14}=\dfrac{1008}{1400}\\\\\dfrac{800}{1400}<\dfrac{875}{1400}<\dfrac{980}{1400}<\dfrac{1008}{1400}[/tex]

therefore

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

Answer:

That their milkshakes need more caramel or less ice cream.

Step-by-step explanation:

We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.

But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.

Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.

Answer:

D

Step-by-step explanation:

The solution is, the value of x is, D) x ≤ -30.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

x + 20 ≤ -10

now, we have to solve this,

at first we subtract 20 from both sides, we get,

x + 20 - 20  ≤ -10 -20

or, x  ≤ -30

Hence, The solution is, the value of x is, D) x ≤ -30.

Answer:

35/6

Step-by-step explanation:

The result of dividing 5/6 by 1/7 is 35/6.

Here, we have,

To divide fractions, we can use the following rule:

To divide one fraction by another, we multiply the first fraction by the reciprocal of the second fraction.

In this case, we have:

(5/6) ÷ (1/7)

To find the reciprocal of a fraction, we simply flip the fraction by swapping the numerator and denominator.

Therefore, the reciprocal of 1/7 is 7/1.

Now, we can rewrite the expression as a multiplication:

(5/6) * (7/1)

Multiplying the numerators and denominators:

(5 * 7) / (6 * 1)

Simplifying:

35/6

Therefore, the result of dividing 5/6 by 1/7 is 35/6.

  x = -1/32y^2

Step-by-step explanation:

Since the focus is to the left of the vertex at a distance of 8 units, the equation can be written as ...

  x -h = 1/(4p)(y -k)^2 . . . . with vertex-focus distance of p and vertex (h, k)

  x = -1/32y^2

The value of  g(x) = 2x² - 4, when g(-2) = 4

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

g(x) = 2x² - 4

The above function is a quadratic function.

The solution of when g(-2):

Substituting the value of x = -2

 g(x) = 2x² - 4

g(x) = 2(-2)² - 4

g(x) = 8 - 4

g(x) = 4

Therefore, the value of g(-2) = 4.
