What are equivalent expressions for 6(y-1) and 64x+80

snow_tiger [21]

To find equivalent expressions, distribute the first one and factor the second one.

$6(y-1) \\ (6*y)+(6*-1) \\ 6y-6 \\ \\ 6(y-1)=6y-6 \\ \\ 64x+80 \\ 16( \frac{64}{16}x+ \frac{80}{16}) \\ 16(4x+5) \\ \\ 64x+80=16(4x+5)$

Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).

siniylev [52]

Answer:

Option b Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$A(-4,-2)\\B(-7,-7)$

step 1

substitute the values in the formula

$d=\sqrt{(-7-(-2))^{2}+(-7-(-4))^{2}}$

step 2

Simplify

$d=\sqrt{(-7+2)^{2}+(-7+4)^{2}}$

step 3

$d=\sqrt{(-5)^{2}+(-3)^{2}}$

step 4

$d=\sqrt{25+9}$

step 5

$d=\sqrt{34}$

therefore

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Find the value of x.

miskamm [114]

Answer:

Step-by-step explanation:

Since we have two secants,

Use this theorem,

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

In other words,

$x + 18 = \frac{130 - 4x + 22}{2}$
