Answer:

[tex]\boxed{\boxed{\sf x=-3}}[/tex]

Step-by-step explanation:

[tex]\sf y = -3x - 2[/tex]

[tex]\sf y=7[/tex]

We'll substitute y into the equation:

[tex]\sf 7 = -3x - 2[/tex]

Switch sides:

[tex]\sf -3x-2=7[/tex]

Add 2 to both sides

[tex]\sf -3x-2+2=7+2[/tex]

[tex]\sf -3x=9[/tex]

Divide both sides by -3:

[tex]\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}[/tex]

[tex]\sf x=-3[/tex]

Therefore, the value of x/solution is -3

Answer:

To determine which equation has a maximum at y =5, you will need to compare their graphs looking only at the x-values between 0 and 27.

Step-by-step explanation:

n= smallest integer

n+2= middle integer

n+4= largest integer

n + n + 4 = 36

2n+ 4 = 36

2n=32

n= 16 which means that the smallest integer is 16

then you substitute it into the equation for the largest integer

n+4=20

16, 18, 20 is the answer

Answer:

cost for 18 apples:  $3.38

$5 will buy 26 apples

Step-by-step explanation:

let 'a' = apples

1.50/8 = cost per apple

$0.1875 for one apple

cost for 18 apples:  0.1875 x 18 = $3.38

5.00 / 0.1875 = number of apples for $5  → 26

Answer:

2/7

Step-by-step explanation:

The solution of fractions after multiplying the two fractions would be [tex]\dfrac{2}{7}[/tex].

Given that,

Multiply the two fractions,

[tex]\dfrac{1}{2} \times \dfrac{4}{7}[/tex]

Used the concept of multiplication which states that,

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, simplify the fractions by multiplying,

[tex]\dfrac{1}{2} \times \dfrac{4}{7}[/tex]

[tex]\dfrac{4}{14}[/tex]

Simplify for the simplest form,

[tex]\dfrac{2}{7}[/tex]

So, the solution is [tex]\dfrac{2}{7}[/tex].

Using the normal distribution, it is found that the correct option is:

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

P(Y < 16) is the p-value of Z when X = 16, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{16 - 20}{2.3}[/tex]

[tex]Z = -1.74[/tex]

[tex]Z = -1.74[/tex] has a p-value of 0.041.

This is valid for the entire population, hence, the correct interpretation is:

Answer:

The equation is 6(x + 10) = 60, and the answer to the equation is 0

Step-by-step explanation:

Start by formatting the problem as [tex]6(x+10)=60[/tex]. Then, use the distributive property so that the problem is [tex]6x + 60 = 60[/tex]. After this, subtract 60 from both sides to isolate the variable, making the problem [tex]6x=0[/tex]. Finally, divide both sides by 0, which will get you an answer of [tex]x=0[/tex].

Answer:

The GCF of 42 and 63 is 21. To calculate the greatest common factor (GCF) of 42 and 63, we need to factor each number (factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42; factors of 63 = 1, 3, 7, 9, 21, 63) and choose the greatest factor that exactly divides both 42 and 63, i.e., 21.
