5(y + 2/5) = -13
what is the value of y

Answer:

y=x

Step-by-step explanation:

slope intercept form:

y= mx +c, where m is the gradient and c is the y-intercept.

Let's rewrite the given equation in the form of y=mx+c, so that we can determine the gradient of the line.

y-4= x-6

y= x -6 +4

y= x -2

Thus, the gradient of the given line is 1.

the product of the gradients of perpendicular lines is -1.

(gradient of line)(1)= -1

gradient of line= 1

Thus, m=1.

y= 1x +c

y= x +c

To find c, substitute a coordinate.

When x= -2, y= -2,

-2= -2 +c

c= -2 +2

c=0.

Thus the equation of the line is y=x.

D)5

Explanation:

opening the bracket, you get :2x+3 = 4x-4

solving further you ,that is collecting like times you will get 2x-4x = -4-6

Therefore,-2x = -10

Dividing both sides by -2,xis equal to 5.

The calculated value of the gcf of 64 and 144 is 16

From the question, we have the following parameters that can be used in our computation:

Expressions = 64 and 144

Expand both expressions

So, we have

64 = 2 * 2 * 2 * 2 * 2 * 2

144 = 2 * 2 * 2 * 2 * 3 * 3

Multiply the common factors

GCF = 2 * 2 * 2 * 2

Evaluate

GCF = 16

Hence, the gcf of 64 and 144 is 16

Answer:

x ≥ 4

Step-by-step explanation:

There is a closed circle at 4 so it means equals

The line goes to the right so that means greater

x ≥ 4

Answer:

D or x≥4

Step-by-step explanation:

The number has to be 4, since the dot lies on it, so that excludes A and B.

It is greater, because the arrow is pointing right instead of left.

Since the circle is closed, then it means that it includes 4.

So, C would not be the answer, because it is read as " x is greater than 4"

it should be D, which is " x is greater than or equal to 4" (since the circle is closed).

Thus, D is the answer

Answer:

A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).

Step-by-step explanation:

The y-intercept of the graph is the height of the leaf at the beginning, that is, 12 ft. This means that point (0, 12) is on the line.

The leaf falls to the ground at a rate of 0.25 feet per second, this means that after 8 seconds, the leaf travel 8*0.25 = 2 ft. Given that it started at 12 ft, its height is 12 - 2 = 10 ft. In other words, the point (8, 10) is on the line. Similarly, its height after 16 seconds is 12 - 16*0.25 = 8 ft, that is, the point (16, 8) is on the line.

Answer:

the answer is D

A line is passing through (0, 12), (8, 10), and (16, 8).

Step-by-step explanation:

When there is one x-intercept, the discriminant is zero.

__

The discriminant is used to compute the difference between the roots. When it is positive, the real roots are different, so there are two x-intercepts.

When the discriminant is zero, there is no difference between the roots, so there is one x-intercept (as here).

When the discriminant is negative, there are no x-intercepts and the two roots are complex.

Step-by-step explanation:

i did this assignment

The types of statement can be used to explain the steps of a proof is postulate and theorem.

A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument is used to prove a theorem by using the deductive system's inference rules to show that the theorem follows logically from the axioms and other theorems that have already been proven.

Guessing and Conjecture is just striking some ideas without any definite conclusion.

A claim that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block.

Thus, the statement used in proof is Postulate or Theorem.

Answer:

√95 cm

Step-by-step explanation:

To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2

The hypotenuse is the c and let one leg be b. You can write:

a^2 + 7^2 = 12^2

a^2 + 49 = 144

Now, you need to solve for a:

a^2 = 144 - 49

a^2 = 95

a = √95 cm, or about 9.75cm
