What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)

Answers

Answer: y=4x+6

Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.

Answer:

[tex]y = 4x+6[/tex]

Step-by-step explanation:

Equation of a line

The equation of a line can be written in the form:

[tex]y = mx+b[/tex]

Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:

[tex]y = 4x+b[/tex]

To find the value of b, we use the point (0,6):

[tex]6=4*0+b[/tex]

Solving:

[tex]b=6[/tex]

Thus, the equation in slope-intercept form of the required line is

[tex]\boxed{y = 4x+6}[/tex]

Find 3 ratios that are equivalent to the given ratio. 6/9

Answers

Answer:

2:3

12:18

18:27

Step-by-step explanation:

Answer:

In order to get equivalent ratios, we can just multiply by a factor! Lets use the factors of 2, 3, 4.

So we have:

[tex]2 * \frac{6}{9}=\frac{2*6}{2*9}=\frac{12}{18}[/tex]

As well as:

[tex]3 * \frac{6}{9}=\frac{3*6}{3*9}=\frac{18}{27}[/tex]

And finally:

[tex]4 * \frac{6}{9}=\frac{4*6}{4*9}=\frac{24}{36}[/tex]

Doreen Schmidt is a chemist. She needs to prepare 32 ounces of a 12% hydrochloric acid solutionFind the amount of 16% solution and the amount of 8% solution she should mix to get this solution

Answers

ANSWER: 16 ounces of the 11% solution and 12 ounces of the 7% solution should be used.

Explanation: Let x be the number of ounces of the 14% solution and 28 - x be the number of ounces of the 7% solution.

The equation you must set up shows the number of ounces of acid added from each solution equals the number of ounces in the 11% solution.

The key thing to remember is that the number of ounces of acid is the amount of solution times the concentration of acid it contains.

Thus,

.11x + .07(28-x) = .11(28).

You can solve this in the usual way, but it helps to clear the decimals by multiplying both sides by a suitable number.

So here goes,

.14x + 1.96 - .07x = 3.08

Multiply both sides by 100:

14x + 196 - 7x = 308.

Now finish solving:

7x = 308 - 196 = 112
x = 112/7 = 16

Then 28-x = 28 - 16 = 12.

Add. Simplify your answer.

A jet and a light plane leave the same airport at the same time and travel in opposite directions at 960 km/h and 560 km/h, respectively. In how many hours will they be 4560 km apart?

Answers

The jet travels a distance of

(960 km/h) t

after time t, while the light plane travels a distance of

(560 km/h) t

The jet is faster than the light plane, so the distance between them is

(960 km/h) t - (560 km/h) t = (400 km/h) t

so the time it takes for them to be 4560 km apart is

(400 km/h) t = 4560 km

==>  t = (4560 km) / (400 km/h)

==>  t = 11.4 h

What is the answer to 6x + 7= -x + 70

Answers

Answer:

x = 9

Step-by-step explanation:

6x + 7 = -x + 70

~Subtract 7 to both sides

6x = -x + 63

~Add x to both sides

7x = 63

~Divide 7 to both sides

x = 9

The area of a rectangle is x²-4x-21
Write down an expression for the width and the length of
the rectangle.​

Answers

Answer:

Step-by-step explanation:

Area of rectangle= Length x Width

and the given Area is a quadratic expression

A=[tex]x^{2} -4x-21[/tex]

We use the factorization method so,

we need 2 numbers that when multiplied we get -21 and when we add/subtract we get -4 so,

A=[tex]x^{2} -7x+3x-21[/tex]

now we simplify,

A=[tex]x(x-7)+3(x-7)[/tex]

A=[tex](x-7)(x+3)[/tex]

This looks familiar doesn't it, when we write the formula for the area of rectangle its

A= Length x Width and the equation here shows that

A= [tex](x-7)(x+3)[/tex]

So the expression for the length is x-7 and

the expression for the width is x+3 i think u have missed maybe some information on the question as such that the perimeter might be missing because length could be either x-7 or even x+3 same goes for width maybe someone can correct me if im wrong

Hey there!

75° + 28° + angle KFG = 180°( being linear pair)

103° + angle KFG = 180°

angle KFG = 180° - 103°

Therefore, angle KFG= 77°

Now;

angle KFG + 28° +22° + X= 180°{ co-interior angle}

77°+28° + 22°+x= 180°

X = 180°-127°

Therefore, X = 53°

y == X+22°= 75° { being alternate angle}

angle KFG+x+z = 180° {sum of interior angle of triangle}

77°+53° + z = 180°

z = 180° - 130°

z= 50°

Therefore, X= 53°, y = 75° and z= 50°.
