Answer:

Step-by-step explanation:

1) You have to create an equation by combining like terms. In the first one, it shows that 5*x + 2 is the same as or equal to 17. So, 5x+2=17. Then, all you have to do it simplify. Move the apples and oranges over (the different terms) so you get 5x=17-2 (whenever you move the numbers across the = sign, it turns into the opposite). 5x=15. X=15/5. X=3

also, for some reason, I can’t view the other images. Is there a way you can put them all into one or something if you want more answers?

Dilate the figure by a scale factor of 0.5 with the origin as the center of dilation. What are the vertices of the image?

Mashutka [201]

Answer:

4. F '(3, 2.5), G '(5, 0.5), H '(1, 0.5)

Step-by-step explanation:

The formula for dilations are

$\left(x_{1}\cdot t_{1},\ y_{1}\cdot t_{1}\right)$ where t1 is the scale factor

F has coordinates (6,5) so you can write

$(6*0.5,5*0.5)$

Multiply 6 by 0.5 and 5 by 0.5 to get

$(3,2.5)$

Next, do G. It has coordinates (10, 1) so you can write

$(10*0.5, 1*0.5)$

Multiply 10 by 0.5 and 1 by 0.5 to get

$(5, 0.5)$

Finally, point H has coordinates (2, 1) so you can write

$(2*0.5, 1*0.5)$

Multiply 2 by 0.5 and 1 by 0.5 to get

$(1, 0.5)$

Hope this helps. Feel free to ask any follow-up questions.

Have a great day! :)

Solve step by step solution then only i can do it plxx

Answer:

<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>

Here angle B is 90°

So $\triangle ABC$ and $\triangle ABD$ Are right angled triangle

So we use Pythagoras thereon for solution

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

First in triangle ABC

perpendicular=p=8cm

Hypontenuse =h =10cm

We need to find base=b

According to Pythagoras thereon

${\boxed{\sf b^2=h^2-p^2}}$

Substitutethe values

$\longrightarrow$ $\sf b^2=10^2-p^2$

$\longrightarrow$ $\sf b={\sqrt {10^2-8^2}}$

$\longrightarrow$ $\sf b={\sqrt{100-64}}$

$\longrightarrow$ $\bf b={\sqrt {36}}$

$\longrightarrow$ $\sf b=6$

$\therefore$ $\overline{BC}=6cm$

BD=BC+CD

$\longrightarrow$ $BD=9+6$

$\longrightarrow$ $BD=15cm$

Now in $\triangle ABD$

Perpendicular=p=8cm

Base =b=15cm

We need to find Hypontenuse =AD(x)

According to Pythagoras thereon

${\boxed {\sf h^2=p^2+b^2}}$

Substitute the values

$\longrightarrow$ $\sf h^2=8^2+15^2$

$\longrightarrow$ $\sf h={\sqrt {8^2+15^2}}$

$\longrightarrow$ $\sf h={\sqrt {64+225}}$

$\longrightarrow$ $\sf h={\sqrt {289}}$

$\longrightarrow$ $\sf h=17cm$

$\therefore$ ${\underline{\boxed{\bf x=17cm}}}$

A, B & C form a triangle where ∠ BAC = 90°.

earnstyle [38]

Answer:

12.9

Step-by-step explanation:

To solve this, you need to use the Pythagorean Theorem: a² + b² = c²

Substituting the numbers into the formula:

(9.4)² + (8.9)² = c²

(88.36) + (79.21) = c²

167.57 = c²

12.9 ≈ c
