Answer:

we need to find out if the following get x = 2 as a final product

-2(x-4) = 4

-2x + 8 = 4

-2x = -4

x = 2

so it is a solution

26/x = 13

26 = 13x

x = 26/13

x = 2

so it’s a solution

-3.8x = -7.4

x = 7.4/3.8 ≠ 2

you get ≈ 1.95

so it’s not a solution

4(x-1) - 3(x-2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -10

so it’s not a solution

A bag contains blue and yellow counters.

ale4655 [162]

Answer:

5.25 : 1

Step-by-step explanation:

If 84% of the counters are blue, then 16% of the counters are yellow.

percentage of yellow counters = 100% - 84% = 16%

blue counters : yellow counters = 84 : 16 (we don't write %)

Now divide with 16, so the second number becomes 1.

$\frac{84}{16} : \frac{16}{16} = 5.25 : 1$

Terry is drawing isosceles triangles with side lengths a, b, and c such that

My name is Ann [436]

9514 1404 393

Answer:

{2, 2, 2}, {2, 3, 3}, {2, 4, 4}, {3, 2, 3}, {3, 3, 2}, {3, 3, 4}, {3, 4, 3}, {4, 2, 4}, {4, 3, 3}, {4, 4, 2}, {5, 2, 5}, {6, 2, 6}

Step-by-step explanation:

The requirement that side lengths be greater than 0 means that ...

y > x > 0

y > z > 0

Then possible values for x and z are 1, 2, 3, and possible values for y are 3, 4, 5, 6, 7.

When we list the possibilities, and exclude those that do not give isosceles triangles, we find the values of {a, b, c} can be those listed above.

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)?

Gwar [14]

Answer:

0, -11

Step-by-step explanation:

y-4=-3(x-(-5))

y-4=-3x-15

y=-3x-15+4

y=-3x-11 the ordered to the origin is -11

the y-intercept is at the point (0, -11)

Hope this helps

Find the missing side of this triangle 6 x 10

IrinaK [193]

Answer:

√136 units

Step-by-step explanation:

We are given that;

The provided triangle is a right triangle.
The measure of the legs are 6 and 10 units.
The hypotenuse of the right triangle is x units.

Since the provided triangle is a right triangle, we can use pythogoras theorem to determine the missing side length of the triangle.

<h3>What is the pythogoras theorem and it's formula?</h3>

Pythogoras theorem is a formula that is used to determine the missing side length of a right triangle, with the following given;

Two side lengths (Legs)
A hypotenuse (Longest side)

Pythogoras theorem is denoted as;

(c)² = (b)² + (a)²

Where, "c" is the hypotenuse; "b" and "a" are the legs.

When we substitute the measure of the two legs and the hypotenuse of the triangle, we get;

(x)² = (10)² + (6)²

Now, let's simplify the equation to determine the value of "x".

⇒ (x)² = 100 + 36 [Evaluating the squares]
⇒ (x)² = 136 [Simplifying the right-hand-side]
⇒ √(x)² = √136 [Taking square root both sides]
⇒ x = √136 ≈ 11.66 units (2 d.p) [Taking square root both sides]

The measure of the missing side is √136 units.
